The FIA will be utilising existing wearable-tech – such as the Cypher Pro Micro Cooler produced by Chillout Motorsports.

The devices combine a shirt with nearly 50 metres of tubes that pump cooled fluid stored in a dedicated box that houses a micro-processor and the technology needed to keep the relevant temperatures down around a driver’s torso.

The temperature at which this will need to be used has now been set at 31C ambient temperature on the FIA sensors placed around a typical F1 venue (there are four weather stations erected at each race), rather than being measured on how hot conditions are in car cockpits, which can quickly reach 50-60C.

In 2026 this system will be mandatory in the cars but for 2025 as the system only will be retro-fitted to cars when the 31C mark is reached, drivers have been given the option of not using it.

But if a driver chooses not to wear a cooling vest in 2025, it is understood they must still carry an extra 500g in ballast within their cockpits to ensure they do not gain a competitive edge by choosing to take this approach.

Hey, everyone living in hot and humid places? We have a tool you might find useful!

This is a calculator from the US government that calculates the wet bulb temperature if you plug in ambient temperature, pressure, and humidity.

If you don't know what the wet bulb temperature is, that's alright, it's not a very well-known term. It's a really simple measurement, though, and it's a useful number to have. It is the temperature that a thermometer would read if its sensor was fully wrapped in wet cotton, and it measures the absolute limit of purely evaporative cooling in given atmospheric conditions.

If the wet bulb temperature is equal to the ambient temperature, do not attempt to cool yourself off with evaporation, and try to minimize sweating as much as possible. In an environment like that, sweat and water can actually heat you up by conducting ambient heat into your core.

Now, let me clarify: you can always cool yourself down if you have access to water that is colder than your body temperature. Pouring that on yourself will wick away heat. But if the wet bulb temperature is equal to ambient, you should dry yourself off immediately after doing so.

If the wet bulb temperature is lower than ambient, though, it means that evaporative cooling is possible. In that case, sweating and getting yourself wet are both helpful.

Hey IPS-N, The "Check Generator" light comes on

when I am running the Drake in extremely cold climates. The light ticks off after about 15 minutes of running, but should I be concerned about any functional issues?

Hello!

That is a known issue in which the thermal sensor designed to detect plasma abnormalities erroneously picks up on the cooler ambient temperatures. If you routinely find yourself working in cold climates, you can recalibrate the sensor to the new normal ambient, but otherwise don’t worry about it.

This story reminds me of a movie I heard about when my Dad was still flying the SR-71 called “The Russians are coming! The Russians are coming!

In 1977, Buz Carpenter and John Murphy’s TDY at Mildenhall, United Kingdom, was extended to support the air tattoo celebration of the Queen's silver jubilee open house. This would be the first public display of an SR-71 since the record-setting speed record in 1974 from New York to London in under two hours

The SR-71 would be part of the static display but roped off so that people could not touch the aircraft. We were advised that, indeed, the Russians were coming. To prevent the Russians or anybody else from exploiting the display. No sensors were left on the aircraft, all fuel had been removed from the tanks, and the plane was heat-soaked to an ambient temperature to prevent infrared cameras from discovering the aircraft's secrets, internal structure, and support systems. We four crewmembers Buz Carpenter, John Murphy, JT Vida, and Tom Alison were standing around the aircraft, answering questions from the crowd when sure enough the Russians showed up in numbers. They took numerous regular and infrared photos. Some of the Russians even had hidden microscopes.

They were a site to see coming up like a convey of quails. It looks like the Salvation Army had outed them. Their dress sense was from a 1930s movie about American mobsters. They were wearing double-breasted suits made from a rougher cloth than one normally sees.

The head of the Soviet delegation is a former MiG-23 fighter pilot who’s quite relaxed and talkative in his demeanor. He asked John and me to drop in on Vladivostok ( the USSR) as a gesture of peaceful relationship.

We just quipped “please forward that request to our state department” 😆. Buz Carpenter

I found this story in Paul Crickmore‘s new book Lockheed Blackbird Beyond the Secret Missions, the missing chapters.

Green Thumb Trinkey springs into existence 🌱💧🌞

With recent work to improve our soil moisture sensing, it could be a nice time to design an 'all-in-one' board for plant and garden hacking. This board has a USB C, so you can plug it right into your computer and read the capacitance of the soil, as well as the ambient light level and temperature + humidity of the onboard AHT20. A QT sensor and 'standard Stemma QT' mounting holes mean you can plug in a VOC, CO2, UV, or PM.2 sensor. The SAMD21E18 can run Arduino or CircuitPython, but we'll also ship it with an example that just spits out CSV data over the serial port for instant interfacing. Coming soon.

Spirktober 2023, Day 4: Water

Two in one day! Who is she? She's powerful! I chose water for the theme of today because the idea of Spock learning to swim was irresistible. I hope you enjoy!

Also posted on AO3 here.

☆ ☆ ☆

Kirk had promised Bones that there was nothing on this planet that could possibly impact their away mission, which, upon reflection, was nearly certainly why things had gone sideways as soon as the shuttle entered the atmosphere. 

It was a milk-run day, as the bridge crew called their less eventful assignments from HQ. They were on the edges of Alpha Quadrant, taking samples of air and water and microbiological life forms from a planet that hadn’t so much as developed a millipede yet. 

The funny thing was, Kirk mused, as Spock carefully guided their dead shuttle towards the endless ocean beneath them, was that if they had decided to beam down to the surface instead, everything would have been fine.

But there was something in the atmosphere that had changed the combustion rate of the engine (“A 0.00085% chance of occurrence, captain,” Spock had said calmly as the engine stuttered into silence) and had derailed their plans for an uneventful couple of hours on the surface of the planet. They hadn’t even taken security officers. Spock’s favorite scientists were monitoring some high-touch fungi growth experiment, and Kirk knew that Spock himself was curious to study a planet so early in its development, so they had elected to go, just themselves. Like a date, Kirk thought, watching Spock expertly slow their fall with the shuttle’s emergency parachute, deploy the inflatable underlayer of the shuttle, and bring them to a careful landing on the surface of the ocean. Naturally our first date goes to hell immediately. 

Spock checked the readouts from the dashboard of the shuttle and raised one eyebrow. God, Kirk loved that eyebrow. “The composition of both the ocean and the air are astonishingly similar to Earth, captain. Certainly M-class, with a breathable atmosphere for oxygen-reliant life forms and a sodium-heavy ocean. Ambient temperature reads at ninety-five degrees Fahrenheit, and water temperature at seventy-eight. ”

“So it’s safe to go outside?” 

Spock hesitated. “Insufficient data. I am unable to determine what factor would have prevented the engine from continuing on impulse power.” 

“But I am not an engine on impulse power, Mr. Spock,” Kirk said, and smiled. He pulled his comm from his belt and flipped it open. “Kirk to Scotty. How are things up there?”

“Oh, just fine, captain,” Scotty’s voice said from the comm. “Everything alright down there? Looked like your engine turned off mid-flight.”

“Something like that, Mr. Scott. Is there anything on the Enterprise’s sensors about the atmosphere that we should be aware of?”

“Negative, captain. All normal readings for an M-Class planet, according to our Mr. Chekov. Shall we beam you up immediately?”

“Oh, leave us for a moment, won’t you? I don’t think there’s anything down here to cause us too much harm.” 

“As you like, captain. I’m sure Mr. Spock would appreciate the chance to take what readings he can.” Spock inclined his head towards the comm, but if Scotty’s consideration of his desires took him by surprise, his face didn’t reveal it. 

“Alright. We’ll check in by the hour. Someone ask Bones to be on standby, if you don’t mind.” 

Spock looked up, eyebrow at high alert, as Scotty asked, “Problem, captain?”

“Not yet, Mr. Scott. But I’d hate to waste the opportunity for a swim, and better safe than sorry. Spock says the water’s warm.” 

Spock spluttered, “I said no such thing, captain,” as Scotty’s cheerful laughter burbled over the comms. “I’ll let him know, captain. Enjoy yourself.” 

“Thank you, Mr. Scott. Kirk out,” Kirk said, and snapped his comm shut with his hip as he pushed himself out of the navigator’s seat. 

“Captain, your leaps of logic never fail to astound,” Spock said, hovering a half-step behind him as Kirk shrugged out of his tunic and pants into just his undershirt and boxer briefs. 

“Come on, Mr. Spock,” Kirk said, and turned to smile at him. “We’re already here. You wanted to take readings of the water. The water is perfectly warm, and it’s a sunny day. There’s not even so much as a jellyfish on this planet to sting me.”

They climbed out on top of the shuttle. The sun was warm against the black of Kirk’s t-shirt, and a light breeze from the direction he thought might have been landward ruffled the surface of the water. Spock, still dressed in science blues and even his boots, relaxed minutely in the warmth. 

“Nice weather, isn’t it?” Kirk said cheerily, and stepped towards the edge of the shuttle. It was less than five feet from the top of the shuttle to the surface of the water. He had dived from higher platforms on Earth for fun before. Spock peered over the edge of the shuttle next to him. 

“Will you join me, Mr. Spock?” Kirk asked. “You’ll have to get closer to the water than this if you care to take samples.” Spock gave the water a side-eyed glance that bordered on distaste, and then it dawned on Kirk. 

“You don’t know how to swim!” 

“Vulcan is a desert planet, captain,” Spock said stiffly. He had his tricorder gripped tightly between both hands. “Swimming would have been an illogical use of a limited and necessary resource.”

“Well, this doesn’t look like a limited resource to me.” Kirk sat on the edge of the shuttle’s roof and slid down towards the inflated platform that kept the shuttle from sinking. It rather reminded him of an inner tube from his childhood. It was rough under his bare feet, and the water that splashed up was pleasantly warm. 

Spock peered down at him from where he remained on top of the shuttle. Kirk looked up at him and planted his hands on his hips. “How were you planning on taking these samples without getting in the water, Mr. Spock?”

“Starfleet standard-issue boots are waterproof, captain. I would have merely remained on the shore and taken samples from the shallowest points.” 

“Ah, but then your samples would have been half-sand, anyway. If you come down here, you’ll get water. Better for your research, I think.” 

Spock narrowed his eyes. He knew when Kirk was teasing him, but Kirk didn’t think he minded as much as he used to. “Come on, Spock,” Kirk said, and held his hand out. “I’m not going to let you drown.” 

Spock didn’t take his hand, but that didn’t surprise Kirk. He did carefully slide down the side of the shuttle to join Kirk on the inflatable, however. “I am significantly more dense than you, captain. Should I fall off and sink, you’d be better off asking Mr. Scott to beam us out.” He levered himself carefully to a seated position, cross-legged, with his back against the shuttle and his tricorder pointed at the water. For a moment, Kirk had a mental image of a child-sized Spock, sitting cross-legged in the desert, watching some sort of insect under a magnifying glass, and his heart twinged. He turned away from his science officer and dipped one foot in the water. It was warm, and slightly gritty---just like he remembered oceans on Earth. He launched himself off the inflatable and into the water. When he resurfaced, Spock was wiping water off his tricorder screen with the edge of his sleeve and frowning at him. 

“I’m sorry, Mr. Spock,” Kirk said, laughing. “Did I ruin your readings?” 

“No,” Spock said stiffly. Kirk smiled at him and tipped his head back, allowing the air in his chest to pull him upwards so that he was floating on the water. Sunshine, and water, and a breeze---these were not normally things he missed while in space. Normally the sight of the stars around him and the comforting hum of the Enterprise’s engine were enough for him. But now, while he had the comforts of gravity and water and warmth, he found it surprisingly pleasant. So, listening to the familiar rustle of Spock doing some sort of science just a few feet away, he closed his eyes and allowed himself to drift.

When he opened his eyes a few minutes later, Spock had taken off his boots and rolled up his pants and was sitting with his feet dangling from the side of the inflatable into the water. Kirk paddled over and treaded water nearby. “What do you think, Mr. Spock?” 

“A curious sensation, captain, but not an unpleasant one.” Spock swung one leg forward, then the other, creating little ripples in the water. 

“I’ll teach you to swim, if you want to get in,” Kirk said. Spock hesitated. “It’s not hard, I promise. Human children can be taught to swim at only a few months old.” 

“I find that difficult to believe, captain.”

“It’s true! Something about it being a familiar environment after nine months in utero.” Spock considered this, and looked up at the sun in the sky above them. 

“I won’t let you drown,” Kirk said again. “I’m a good swimmer.” 

Slowly, so slowly that Kirk was certain that Spock was still considering the logic of submerging his desert-bred self into a body of water, Spock lifted the strap of his tricorder over his head and set it carefully aside. He tucked it against the wall of the shuttle and patted it once, like he wanted to be sure it wouldn’t fall off and float away, taking all his readings with it. Then Spock shuffled himself further towards the edge of the inflatable, peering down at the water. Kirk smiled at him encouragingly, and Spock gave one short, sharp nod. Then he shoved himself off the inflatable and dropped down into the water. 

Something that Kirk had noticed about his first officer in the two years they’d been working together was that the man was graceful beyond reason. Something about his height, his posture, or his strength made his movements seem measured, as careful as his speech was, every action intentional. Sometimes, when they sparred together or Kirk was able to see Spock fighting on missions, Kirk thought he was wasted as a Starfleet officer. He should have been a dancer instead. It was distinctly humorous, then, that the same grace did not translate to Spock in water. Spock’s head broke the surface only a second after vanishing; not even enough time for Kirk to have to dive down to grab him. His hair was a mess, matted down around his eyebrows, the pointed tips of his ears breaking through the black. He spat water out and immediately swallowed more, his wildly swinging arms created waves around them. 

“How are you doing, Mr. Spock?” Kirk asked, staying clear of his arms. He could only imagine that his legs were doing the same beneath the surface, and didn’t care to be kicked. 

“Poorly, captain,” Spock said. Kirk laughed until he cried. 

☆ ☆ ☆

Spock learned quickly, and after a few minutes was floating next to Kirk, looking up at the sky. The composition of the atmosphere was different enough that the sky was not the blue of Earth but closer to a teal, a color Kirk found most pleasing. He could feel the occasional swish of Spock’s hands through the water as he adjusted his equilibrium. 

The moment was broken with the crackle of his comm, and with a sigh he pulled himself back to the inflatable. He grabbed the comm and flipped it open. “Kirk here.” 

“Sorry to ruin your party, captain, but new orders just arrived. Someone --- or something --- crossed the neutral zone. We’re to rendezvous with the U.S.S. Valiant in two days, and Admiral Archer wants to speak with you.”

“Alright, Scotty. Give us a minute to prepare and then we’re ready for beam-up.” 

“Apologies, captain,” Scotty said, and then Kirk heard the disguised laughter in his voice. “But Archer wants you right this moment.” 

“Tell the admiral---” Kirk started, 

“No can do, captain,” Scotty said, and Spock sat upright as a peal of Uhura’s laughter came through the comm as well. “Locked onto your signal, beaming you up now.” 

“Scotty, I swear to---” 

Kirk and Spock materialized, dripping wet, in just undershirts and boxers, onto the transportation pad in front of a laughing Scotty and Chekov. Kirk was standing, as he’d had the good fortune to be upright when the beam started; Spock, who had been mostly horizontal in the water, was laying flat on his back. Kirk offered him a hand, which Spock roundly ignored in favor of climbing to his bare feet while his clothing squelched around him. He straightened and clasped his hands behind his back; the dignified posture did nothing for his hair, which dripped water steadily onto his forehead and down his nose. 

“Truly, my apologies, captain,” Scotty said, wheezing. “But Archer said immediately, and we’ve already got the shuttle in a tractor beam.” 

“Please ensure the safekeeping of my tricorder, Mr. Scott,” Spock said, in funereal tones. 

“Yes, Mr. Spock,” Scotty said. “Shame to lose any of the work you did.” 

“Indeed,” Spock said. He inclined his head to Kirk. “Excuse me, captain.” He walked away, and every step left a watery footprint behind until the door to the transporter room slid shut behind him. Only when Spock was gone did Kirk allow his own laughter to bubble out. 

“I’d like to be a fly on the wall when an ensign dares to do a double-take at him, gentlemen,” Kirk said. “Now let’s go see who’s starting trouble.”

In the far future, you have your own personal robotic companion! And let's just say, you've made particular modifications to it~ Nothing so relaxing as coming home after work, stripping down, and crawling inside your robot for a nap inside its padded synthetic belly with calming music/asmr playing, temperature control, a soothing belly massage routine; like a mobile sensory deprivation tank, as it goes about house chores with you inside~

These robot companions are amazing! Their base model is for helping around the house but you are able to add on mods that can change them to your specifications. To my excitement I'm able to add in a special compartment in their "stomach" panel that are able to work as a womb of sorts. It has special settings as well that make it even more comfortable whenever I need some time away from the world.

My robot has the plush body, expandable "womb", extra womb padding, noise machine, health metrics monitor, and temperature regulation. It's the perfect place to hang out in my opinion. My sweet robot seems to have a ball carrying me around any time I need to forget about my life to hide away. I always feel their hands rubbing around their belly, eager to feel how their body has changed and check on how I'm doing. Sometimes I wonder if there is something extra with the robot since they seem to really enjoy carrying me around.

With all the monitors and sensors they know when I need to eat, drink, and get out to use the bathroom. It is a bit complicated while "in utero"—there are two panels, one for the womb and the second for the stomach, that have to opened in order for anything to comd in or out. Or when it's packaged snacks and bottled/canned drinks my robot swallows them and they are brought straight into the womb. What's really strange is when I get hungry the robot automatically has a stomach growling noise to alert them of my hunger. They're attuned to my body's needs. It was weird when they originally had to integrate with me (strange futuristic technology that I still can't understand) but now I don't forget to take care of myself. Someone else does it for me!

My favorite part about the womb is how I could make it feel as if I were really in a womb. I keep myself at a perfectly warm temperature that is pleasantly comfortable, being lulled to sleep more than I'll readily admit. The ambient noises are interesting as well. With the long list of options I often find myself picking the heart beat because it is the most soothing sound. The womb even pulsates as if there was a heart pumping blood throughout the body. Sometimes I add on a breathing noise that makes my stays even more peaceful. It takes a too much coaxing from my robot for me to leave when I am too stubborn to leave. They always promise me that there's always tomorrow to hideaway in their womb. It's addictive to be huddled away in my robot.

I don't ever want to leave. I'm not really sure that my robot wants me to either.

AMBIENT TEMPERATURE SENSORS: ENHANCING SOLAR ENERGY PERFORMANCE

In the realm of solar energy, maximizing efficiency and performance is a constant goal. One often overlooked yet critical component in achieving this is the ambient temperature sensor. These sensors play a pivotal role in monitoring and managing the environmental conditions that directly affect the performance of solar panels. Understanding the importance of ambient temperature sensors can help optimize solar energy systems and ensure they operate at peak efficiency.

What is an Ambient Temperature Sensor?

An ambient temperature sensor is a device that measures the temperature of the air surrounding a particular environment or system. In the context of solar energy, these sensors provide real-time data on the atmospheric temperature around solar panels. This information is crucial for assessing the impact of temperature on the efficiency and longevity of solar panels.

How Ambient Temperature Affects Solar Panels

Solar panels convert sunlight into electricity through photovoltaic cells. While this process is highly efficient, it is also sensitive to temperature changes. The performance of solar panels is affected by ambient temperature in several ways:

1.      Efficiency Drop at High Temperatures

Solar panels are typically tested and rated at a standard temperature of 25°C (77°F). However, as the ambient temperature rises, the efficiency of the photovoltaic cells decreases. This is because higher temperatures increase the resistance in the solar cells, reducing their ability to convert sunlight into electricity.

2.      Increased Degradation Rate

Prolonged exposure to high temperatures can accelerate the degradation of solar panels. Over time, this can lead to a significant reduction in their overall performance and lifespan. Monitoring ambient temperature helps in identifying and mitigating these effects.

3.      Impact on System Components

Not only do the solar panels themselves get affected by high temperatures, but other components of the solar power system, such as inverters and batteries, can also experience reduced performance and increased wear and tear.

The Role of Ambient Temperature Sensors

Ambient temperature sensors are crucial for monitoring and managing the thermal conditions around solar panels. Here are some key roles they play in enhancing solar energy performance:

1.      Real-Time Monitoring and Data Collection

Ambient temperature sensors provide continuous, real-time data on the atmospheric conditions around solar panels. This data is essential for understanding how temperature variations affect the performance of the solar power system. By analyzing this information, operators can make informed decisions to optimize system performance.

2.      Improving Efficiency

By integrating ambient temperature data with the overall monitoring system, solar power operators can adjust the operation of the panels to maximize efficiency. For instance, during peak temperature hours, it may be beneficial to adjust the angle of the panels or implement cooling mechanisms to reduce the impact of heat on the system.

3.      Preventive Maintenance

Regular monitoring of ambient temperature helps in identifying potential issues before they become significant problems. For example, if a solar panel consistently operates at high temperatures, it may indicate that the cooling system is not functioning correctly or that the panels need cleaning to reduce heat absorption.

4.      Enhanced System Design

During the design and planning phases of solar power installations, ambient temperature data is used to select appropriate materials and technologies that can withstand the local climate conditions. This ensures that the solar power system is built to perform optimally throughout its lifespan.

5.      Energy Yield Predictions

Accurate ambient temperature measurements contribute to more reliable energy yield predictions. By factoring in temperature variations, solar power operators can provide more accurate forecasts of energy production, which is crucial for grid integration and energy management.

Choosing the Right Ambient Temperature Sensor

When selecting an ambient temperature sensor for a solar power system, several factors should be considered:

Accuracy: High accuracy ensures reliable data collection and analysis.

Response Time: Fast response times are essential for real-time monitoring and adjustments.

Durability: The sensor should be robust and capable of withstanding harsh environmental conditions.

Integration: The sensor should easily integrate with existing solar monitoring systems for seamless data collection and analysis.

Conclusion

Ambient temperature sensors are vital components in the quest for optimizing solar energy performance. By providing real-time data on environmental conditions, these sensors enable solar power systems to operate more efficiently, enhance their longevity, and ensure reliable energy production. As the demand for renewable energy continues to rise, the role of ambient temperature sensors in maintaining and improving the performance of solar power systems will become increasingly important. Investing in high-quality ambient temperature sensors is a strategic move towards achieving sustainable and efficient solar energy production, ultimately contributing to a greener future.

Wearable tech for space station research

Many of us wear devices that count our steps, measure our heart rate, track sleep patterns, and more. This information can help us make healthy decisions—research shows the devices encourage people to move more, for example—and could flag possible problems, such as an irregular heartbeat.

Wearable monitors also have become common tools for research on human health, including studies on the International Space Station. Astronauts have worn special watches, headbands, vests, and other devices to help scientists examine sleep quality, effectiveness of exercise, heart health, and more.

Warm to the core

Spaceflight can affect body temperature regulation and daily rhythms due to factors such as the absence of convection (a natural process that transfers heat away from the body) and changes in the cardiovascular and metabolic systems.

A current investigation from ESA (European Space Agency), Thermo-Mini or T-Mini examines how the body regulates its core temperature during spaceflight. The study uses a non-invasive headband monitor that astronauts can wear for hours at a time.

Data from the monitor allow researchers to determine the effect on body temperature from environmental and physiological factors such as room temperature and humidity, time of day, and physical stress. The same type of sensor is already used on Earth for research in clinical environments, such as improving incubators, and studies of how hotter environments affect human health.

Thermolab, an earlier ESA investigation, examined thermoregulatory and cardiovascular adaptations during rest and exercise in microgravity. Researchers found that core body temperature rises higher and faster during exercise in space than on Earth and that the increase was sustained during rest, a phenomenon that could affect the health of crew members on long-term spaceflight.

The finding also raises questions about the thermoregulatory set point humans are assumed to have as well as our ability to adapt to climate change on Earth.

To sleep, perchance to dream

Spaceflight is known to disrupt sleep-wake patterns. Actiwatch Spectrum, a device worn on the wrist, contains an accelerometer to measure motion and photodetectors to monitor ambient lighting. It is an upgrade of previous technology used on the space station to monitor the length and quality of crew member sleep.

Data from earlier missions show that crew members slept significantly less during spaceflight than before and after. The Actiwatch Sleep-Long investigation used an earlier version of the device to examine how ambient light affects the sleep-wake cycle and found an association between sleep deficiency and changes during spaceflight in circadian patterns, or the body's response to a normal 24-hour light and dark cycle.

Follow-up studies are testing lighting systems to address these effects and help astronauts maintain healthy circadian rhythms.

Wearable Monitoring tested a lightweight vest with embedded sensors to monitor heart rate and breathing patterns during sleep and help determine whether changes in heart activity affect sleep quality. The technology offers a significant advantage by monitoring heart activity without waking the test subject and could help patients on Earth with sleep disorders.

Researchers reported positive performance and good quality of recorded signals, suggesting that the vest can contribute to comprehensive monitoring of individual health on future spaceflight and in some settings on Earth as well.

These and other studies support development of countermeasures to improve sleep for crew members, helping to maintain alertness and lessen fatigue during missions.

(Not) waiting to exhale

Humans exhale carbon dioxide and too much of it can build up in closed environments, causing headaches, dizziness, and other symptoms. Spacecraft have systems to remove this substance from cabin air, but pockets of carbon dioxide can form and be difficult to detect and remove.

Personal CO2 Monitor tested specially designed sensors attached to clothing to monitor the wearer's immediate surroundings. Researchers reported that the devices functioned adequately as either crew-worn or static monitors, an important step toward using them to determine how carbon dioxide behaves in enclosed systems like spacecraft.

Radiation in real time

EVARM, an investigation from CSA (Canadian Space Agency), used small wireless dosimeters carried in a pocket to measure radiation exposure during spacewalks. The data showed that this method is a feasible way to measure radiation exposure, which could help focus routine dosage monitoring where it is most needed. Any shielding and countermeasures developed also could help protect people who work in high-radiation areas on Earth.

ESA's Active Dosimeter tested a radiation dosimeter worn by crew members to measure changes in their exposure over time based on the space station's orbit and altitude, the solar cycle, and solar flares. Measurements from the device allowed researchers to analyze radiation dosage across an entire space mission.

The Active Dosimeter also was among the instruments used to measure radiation on NASA's Orion spacecraft during its 25.5-day uncrewed Artemis I mission around the moon and back in 2022.

Another device tested on the space station and then on Artemis I, AstroRad Vest is designed to protect astronauts from solar particle events. Researchers used these and other radiation measuring devices to show that Orion's design can protect its crew from potentially hazardous radiation levels during lunar missions.

The International Space Station serves as an important testbed for these technologies and many others being developed for future missions to the moon and beyond.

Weaponized (Jedi: Survivor)

For @incorrectpizza. Thank you for the prompt! Here's what I came up with:

BD-1 receives new information about Cal on Nova Garon, and he struggles to understand what this means for Cal. BD perspective, ~1800 words, angst, dark side powers. And major Jedi: Survivor spoilers!

incorrectpizza asked:

BD, Nova Garon, shivering? Not sure if that combo will make anything click in your fic writer brain, but figured I'd send something just in case...everything on your prompt list was really great, so hard to pick three.

-

Multiple data streams coursed through BD-1 at any given moment, analytical processes compiling, sorting, categorizing to create an understanding of a situation.  He perched on Cal’s back in Bode’s Imperial officer quarters on Nova Garon, and he was forced to compile many, many things at once.

The easiest thing he needed to understand was the map, and the way back to the ship.  That was all surface level, simple calculations BD could handle even when powered down.  That was easy.

Far more complex was the problem of understanding Bode.  Bode had taken his daughter and ran from a confrontation with Cal, and BD was attempting to process what had happened.  

Cal had tried to talk, and Bode Akuna had fled.  Bode Akuna, who had always treated BD-1 with kindness.  Bode Akuna, who had called Cal important words like “brother.”  Bode Akuna, who had pulled BD’s Master Cordova aside, who had aimed a blaster at him, who had fired at point blank range.  Bode Akuna, who had threatened BD-1 after he tried to help his master.  Bode Akuna, who Cal said had caused Cere to die.

Dead meant no return.  It meant no rebooting, no correction, no healing, no recovery.  It meant gone.  His friends Master Cordova and Cere were gone.

BD did not, could not understand it.  He ran the information backwards and forwards, a whir under the surface that did not rest.  He had had many empathy circuits added, treasures from Master Cordova installed long ago.  But he did not have -- rage.  Anger.  He could not calculate them, and instead there was only a terrible hollowness arcing through his circuits.  A sense of something -- someone -- missing.  It was a feeling he had never identified before in all his cycles.

But missing Master Cordova, and Cere, and the bubbling confusion about Bode, it all hummed in the background.  For now he clung to the back of Cal’s clothing, a stolen Imperial officer’s uniform, and BD knew that something was very wrong.

Biometrics from Cal were easy to pick up from this close vicinity.  Respiration, heart rate, body temperature, they were all simple to read at this distance.  It helped him to help Cal; countless times he had had a stim ready to go, waiting only for Cal’s command, as he watched vital signs spike to dangerous levels.  

Cal ran from Bode’s quarters.  There were no troopers here, not yet, though BD knew that they were coming.  BD also knew that Cal was physically unharmed.  Yet Cal’s heart rate climbed, higher and higher.  He panted, shoulders rising and falling so steeply that BD kept having to readjust his grip.  He shook as if he was desperately cold, but the ambient temperature was adequate for humans.  Every metric suggested that Cal was badly, badly wounded.

Cal charged forward into the next room, and BD braced himself for the wave of troopers coming at them.  Cal drew his lightsaber.

“Get out of my way,” he snarled.

And Cal changed.

BD’s sensors never told him, exactly, when Cal used the Force.  It was a thing that could never be sensed by his kind.  But BD had learned when to suspect it, and he was frequently correct.  Sometimes it came when Cal’s heart rate rose with effort, and sweat beaded on his head; other times his heart rate lowered as Cal focused and connected in silence.  When Cal felt a memory through the Force, BD knew sometimes it staggered him, shifted his balance, disoriented him; BD would wait patiently for Cal to come back.  All of this was familiar to him after these many rotations together.

BD had never seen him use the Force like this.

It was all BD could do to hold on tight as Cal stormed through the room, lightsaber flashing, his breath fast and choppy.  He was used to Cal moving unpredictably by what his parameters listed as normal human standards, jumping higher and farther and faster than they were supposed to, recovering more quickly, withstanding more injury.  

Even with that baseline for reference, Cal whirred through the room at speeds that seemed impossible for an organic, while the droids and troopers surrounding them moved sluggishly as if paralyzed.  BD knew how many swings and parries it should take for certain enemies to fall when Cal engaged them.  Their training and armor, as well as Cal’s own fighting style, created a reliable average.  They were not following the average now.

Trooper after trooper fell after a single blow, their arms severed, their circuits sparking, their bodies limp.  BD clung tighter.  After less than a minute, Cal stood in the center of the room, surrounded by the dead.

Cal normally took a moment after a battle to stop.  He called it centering himself.  He would usually check in with BD, patch up, and meditate briefly -- a few seconds -- enough to help himself “reset.”  For an instant, BD waited for the pause, hoping it would help Cal’s vitals normalize.

He did not rest.  He did not reset.  He screamed “Bode!” in a strained, terrible voice, and he ran.  

He only skidded to a stop in front of a vast blast door, triple-locked with massive round bolts. BD tried to beep a warning to Cal.  These doors didn’t look sliceable with his regular setup.  They would have to find another way --

Cal flung out his hands, fingers curling and shaking with effort.  He twisted his hands into the air, groaning, and the doors groaned too, their massive locks straining, shearing, sparking.  With a growl Cal hurled his hands wide and the door shrieked open, the gnarled wreckage of the locks flying into the walls with a loud clatter.

Cal was running again.  “Have to hurry,” he spat. Troopers, Purge troopers, and probe droids poured from the next doorway towards him.  BD readied a stim.  

Cal wrapped his arms around himself tightly, then pushed out.  BD did not need the Force to understand that Cal had used it again, to see the way he flew and struck and shattered the enemies before them.  BD dug in deeper against Cal’s back, hoping Cal would remember that he was there, but Cal’s vitals crested even higher, into the red.  

The last stormtrooper crumpled beneath his lightsaber, and Cal bellowed, “Bode!”

BD watched as Cal approached another sealed blast door, as he strained and ripped the door apart. He struggled to assimilate this new data.  Perhaps these were simply new powers in the Force that Cal had acquired.  It had happened many times during their journeys together, that suddenly Cal moved in an unexpected way or the environment changed around them abruptly.  Usually all it took was a simple “Broop?” from BD for Cal to explain something had shifted, that he had remembered something old, or learned something new.

He tried a little beep.  It went unanswered, and he clung to Cal, bouncing on his back as Cal sprinted.

Again, the lightsaber flashed.  The troopers fell, their falls unnaturally slow.  Again Cal’s heart rate spiked uncomfortably high.  Cal took a hit and staggered back, clapping a hand to his shoulder.

“I need a stim, BD!” Cal snapped.

BD tossed him the readied stim as quickly as ever, but his circuits whirred, analyzing Cal’s voice.  BD knew he didn’t understand all of the intricacies of human vocalizations, but… Cal didn’t talk that way to BD.  

He just didn’t. 

Cal took the stim, and he kept fighting.

--

BD hopped up to Cal’s back.  Cal stood over Commander Denvik, who lay choking on the ground, his breath ragged.

“Give the Inquisitors my regards,” said Cal, his voice flat and cold.  He turned away to head them back to the Mantis, and BD’s processors whirred mightily, trying to create sense of everything that had just happened. 

Bode had hurt Cal.  He had hurt all of them.  He was trying to keep them from finding a place safe from the Empire, from Tanalorr.

Cere and Master Cordova were dead.  Gone.  This had hurt Cal more than many injuries.  

Tanalorr was being taken away from Cal and their friends, and they were scared.

This information all made sense, though there were still some parts that were confusing.  BD did not know if he would ever understand what had made Bode do these things.  He did not know if he could understand what Cal was doing, either.

Cal had hurt Commander Denvik.  Cal had to hurt many people to survive, to protect his family.  BD understood that much.  But he had never seen Cal hold a person in the air like this with the Force.  He had never seen him scream like that.

He had seen Inquisitors do that.

Even Merrin, who BD knew used the Force in a different way than Cal and Cere and Master Cordova, had been frightened.  Though BD was not usually close enough to get her vitals, he still recognized that normally Merrin was calm and cool.  The way she had pled and shouted for Cal to stop was not normal.  

BD did not know if he could feel fear like an organic could.  But he felt something twitching through his circuits, a collation of the data, a worrisome conclusion.  Cal was hurt on the inside, where a stim or a friendly beep could not help him.  He was hurt very badly.

Cal stalked towards the exit, sensing the right path without needing BD’s map.  BD leaned his head over Cal’s shoulder, tapping him with one leg.  “Boop?” he asked.  Are you okay?

“I’m all right,” said Cal, struggling with the words.  His shoulders heaved; he was still trying to catch his breath.

“Beep?”  Are you sure?

“I’m fine, buddy.”  He swallowed.  His voice cracked.  “You don’t have to worry about me.”

BD cared very much about Cal.  If his empathy circuits produced something like love, love was absolutely what he felt for Cal.  He would always love him, no matter what.

But he knew worry, now.  Worry that Cal was different.  Worry that all the hurt showing in his vitals could come out, that the hurt itself could be a weapon. Not only that, but perhaps the weapon was one that Cal did not know how to control.  A weapon that scared Merrin; a weapon that could hurt Cal, too.

BD-1 settled down against Cal’s shoulder, thrumming with twin streams of love and worry.  He let out one more little beep.  Please be careful.

Cal stopped, reaching up to touch BD’s foot.  He took a deep breath.  His heart rate slowly, slowly lowered, and when he spoke, he sounded like Cal again.

“I will, Beedee.  …Promise.”

Since there has been some interest in my current intake, here is it broke down. I have tried numerous setups but this custom OEM+ version is the best and passes stupid SMOG visual check.

I also intensely studied the 2.5RS forums and looked at dyno charts showing that this IS the best when combined with a 2.25" cat back exhaust and equal length headers. Trust me!

This was a lot work as well as trial and error and willingness to start over again and redo it again several times. I think this was also the lightest combo if you trying to reduce weight.

One of a kind custom intake for the naturally aspirated Subaru EJ25D....

First up is you need the intake tract/duct and hoses from an earlier model Subaru Impreza or any Subaru that has this intake tube vs the stock version with the "torque box" behind the throttle body. Junkyard is your best buddy.

I had expensive high performance mandrel bent blah blah blah intakes which I constantly struggled with keeping the metal tubing cool (I used a laser temp gauge). This plastic is basically the same but rarely gets too hot to touch. So, actually a cold air intake if you keep reading.

Since the entire manifold needed to come out, I painted it wrinkle red and polished the runners and throttle inlet.

The reason I removed the manifold was to install stainless studs to make installing the 10mm thick teflon spacers and 2 sets of gaskets easier. Similar to 8mm Grimmspeed phenolic (previously installed) but thicker. This mod makes a big difference, the entire manifold now stays cool. No more engine block heat soak, only ambient engine bay heat.

"For every 5 degree reduction in temperature, increases power by 1%"

You have to extend the EGR tube and possibly grind your ignition coil pack mounts lower. Because the entire manifold assembly will be sitting ~12mm higher.

I was fortunate enough to work with the gasket maker. So he made 10mm teflon intake manifold spacers and a matching prototype 10mm throttle body spacer! Again 2 gaskets to ensure no leaks. Not sure if these were ever made available afterwards since I was the first car.

This spacer combo increased plenum volume as well as helped to keep heat transfer drastically reduced.

Using my custom ported, polished and knife edged throttle body that I did myself with the coolant hose permanently bypassed and the cruise control bits removed. Keep in mind you will need longer bolts if you use a spacer here. Definitely improved throttle response after just the throttle body swap.

I scored this GC8 v3 factory resonator/cold air intake inlet from the UK. It's what goes with those fender plugs. Grabs cold air from inside the fender behind the corner light up high, so no chance of sucking up water. FWIW, You really shouldn't just delete the "snorkus", seriously, it's just gonna mess up your MAF sensor.

I was also able to make the resonator from a SVX work in the 04 Outback with some persuasion. It too takes air from the same location but the box was hard to cram in the fender.

The intake tract will work with whatever air filter box but in order to use the EUDM WRX intake inlet/resonator you will need the matching filter housing box from an earlier model or have to drill a new mounting hole. You will need both halves!

BEST panel filter on the market IS made by Grimmspeed! Don't waste your money on any other filter! I also added a Filter Wears waterproof inlet cover/pre-filter to the resonator just incase of water spray. The factory option fender plug fills that hole.

And I'm not sure if this was an upgrade or not but here is the JDM JECS MAF I am also using. Used DEI gold heat reflective tape to keep it cool and extend the life. Possibly more consistent/accurate readings?

The only other things installed are a Weapon R catch can to the PVC, which DOES keep some crap out of the intake tract and off the throttle body but probably no real performance advantage. Plus a heat/flame resistant "sock", same as around my fluid reservoirs, over the bendy/flexible bit of the intake tract just after the MAF. That area is prone to splitting/cracking with heat and age!

Now for treasure at the end of the rainbow! I am actually gonna give you nerds the mother fucking part numbers! These can be life savers when searching for parts.

*You might have to make or reuse your PVC, crankcase, IAC valve hoses. So grab whatever is attached if your at the junkyard or hit up the auto parts store.

SR-71 pilot recalls when a Soviet MiG-23 pilot asked him to bring his Blackbird at Vladivostok as a gesture of peaceful relationship. He answered him to forward his request to US state department.

The Blackbird 🐦‍⬛

What aviation geek doesn’t love speed, new technologies, advanced manufacturing methods, and the mysteries of a secret government program? Many aircraft embody these features, but none come close to the Lockheed SR-71 Blackbird.

It could fly over Vietnam in eight minutes, its electronic counter measures were so advanced that they are still in use today on other airplanes and remain top-secret, had tires filled with nitrogen, and was made from one of the most expensive metals on earth. And, it’s still the world’s fastest plane.

CLICK HERE to see The Aviation Geek Club contributor Linda Sheffield’s T-shirt designs! Linda has a personal relationship with the SR-71 because her father Butch Sheffield flew the Blackbird from test flight in 1965 until 1973. Butch’s Granddaughter’s Lisa Burroughs and Susan Miller are graphic designers. They designed most of the merchandise that is for sale on Threadless. A percentage of the profits go to Flight Test Museum at Edwards Air Force Base. This nonprofit charity is personal to the Sheffield family because they are raising money to house SR-71, #955. This was the first Blackbird that Butch Sheffield flew on Oct. 4, 1965.

For speed, innovation and secrecy, no aircraft of its era came close to the SR-71 Blackbird.

First public display since the 1976 record-setting speed record

As told by Paul Crickmore in his book Lockheed Blackbird: Beyond the Secret Missions – The Missing Chapters, in 1977, Blackbird pilot Buz Carpenter and RSO John Murphy’s TDY at Mildenhall, United Kingdom, was extended to support the air tattoo celebration of the Queen’s silver jubilee open house. This would be the first public display of an SR-71 since the record-setting speed record in 1976 from New York to London in under two hours.

Carpenter recalls;

‘The SR-71 would be part of the static display but roped off so that people could not touch the aircraft. We were advised that, indeed, the Russians were coming. To prevent the Russians or anybody else from exploiting the display. No sensors were left on the aircraft, all fuel had been removed from the tanks, and the plane was heat-soaked to an ambient temperature to prevent infrared cameras from discovering the aircraft’s secrets, internal structure, and support systems. We four crewmembers Buz Carpenter, John Murphy, JT Vida, and Tom Alison were standing around the aircraft, answering questions from the crowd when sure enough the Russians showed up in numbers. They took numerous regular and infrared photos. Some of the Russians even had hidden microscopes.

Soviet MiG-23 pilot asks to bring an SR-71 at Vladivostok

‘It looks like the Salvation Army had outed them. Their dress sense was from a 1930s movie about American mobsters. They were wearing double-breasted suits made from a rougher cloth than one normally sees.

‘The head of the Soviet delegation is a former MiG-23 fighter pilot who’s quite relaxed and talkative in his demeanor. He asked John and me to drop in on Vladivostok (the USSR) as a gesture of peaceful relationship.

‘We just quipped “please forward that request to our state department.” Buz Carpenter.’
