Use a Deep Hole? 

I was thinking about saying you couldn’t dig a mile deep. There are boreholes, up to 12 miles deep. The boreholes aren’t more than a foot or two wide. What would we do with a mile deep shaft? My first thought was a rail gun using electromagnetic rails on all four sides to push a ball out of the hole to the top and blast it into orbit.  Then I saw this video, I was crushed, then again, what about…

"Into the Sunlight: NASA's Solar Sail Revolution"

[smellslikejail]

Sam lurched forward onto the desk, arms catching himself before he face planted. "What'd you say dad?" He looked away from the desk and to the door he entered. He froze. This...this was not the same room. "Dad?" Sam called a little louder.

He eased off the chair and noticed something. All his clothes looked brand new, but in all black. The bold print of his Michael Jordan shirt was gone. "Oh..."

The rest of the way back into the Arcade was the same, just...really empty. And clean! He'd never seen the Arcade this clean before. "Dad?!" Sam yelled. No reply. "D...dad?" The last call for his dad was quiet and scared. The Arcade was so empty and sad. The Tron cabinet was blank, just like all the other ones.

A loud sound blasted overhead and Sam booked it to the other side of the room. There was a small Sam sized hole between one of the cabinets and the wall. Good for hiding from fathers. He shoved himself in and waited. ---- Dyson was just as bored as Clu was. Rinzler seemed that way too. They both stood outside the Line where the Solarsailer was finishing up it's first load of supplies to be shipped to the Outlands. Dyson wanted to make sure nothing went wrong. The rebels in the City were becoming more and more of a nuisance.

"Alright, let's go meet them at-" He heard the sound of the portal before he saw it. Both of the programs spun around and saw the beam of light radiating from deep in the City. A moment later they got dual pings from Clu. Dyson looked at Rinzler. Rinzler looked back. [User]. "My thoughts exactly." The both ran and activated their lightcycles. At least something interesting was happening.

The cycle had started like any other that his processor could recall. Oh there were the early cycles where he'd almost anticipate Flynn's arrival. So they could work together. He was not that naive anymore. Clu had risen up against his User, for the safety of the System and the Programs in it. Clu had driven the User out of the System and kept him out.

He'd Purged the ISOs and destroyed their cities. With them gone, the Gridbugs had dwindled in numbers. There were swarms every now and again but those could be easily driven back out into the Outlands.

Flynn wasn't so easily deterred. He'd try but Clu had changed the permissions. He had to get by him first and Clu wasn't about to let that happen anytime soon.

But he was puzzled as he looked at the console. This was not Flynn. Clu recognized Flynn's keystrokes. This was...impulsive beyond even Flynn. At first he had denied the requests and became amused as they kept coming. He tapped his lips with a gloved finger as he considered.

If this wasn't, in fact, Flynn, then who was it? Obviously someone Flynn trusted at the console. The possibility that it was the famed Alan_One crossed his processor and wouldn't that be something? To match wits with the User that had created Tron. But that possibility didn't match up with the apparent keystrokes.

The cycles had gotten...tedious. There was the Resistance. Led by some mechanic called Beck who loved playing dress up and a Commander that had gone rogue. They'd suffered a serious setback at the loss of Tron. The Security Program had surrendered willingly for Flynn's safety.

Clu raised a brow at the Access Approved line. He hadn't approved that. And then he pinched the bridge of his nose as he sent pings Dyson and Rinzler's way. And for good measure, he sent pings to any Sentries or Black Guard that were in the vicinity of the Portal's entrance. The Admin had meant to move the entrance somewhere more strategic but that hadn't occurred yet. Well, he wanted something different to happen this cycle.

(🇮🇹 nel primo commento😊) 🇬🇧 Let's go back to talk about the physics phenomenon of radiation pressure! (I'm referring to my second post😉) When a comet comes near a star it starts releasing gases in a process called outgassing. This produces a visible "coma" and sometimes a tail: the one we see in every single comet representation 🌠 This coma feels a force exerted by the star's radiation pressure, that causes the formation of a tail oriented in a way that it always points away from the star. It may feel a little counterintuitive but the tail does not "follow" the path of the comet but stays radial to its orbit around the star! This is because the pressure of the star's radiation literally pushes the particles of the coma and tail away (#socialdistance at its finest guys, the tail can reach a length of 3.8 astronomical units!!). Here I chose to show you the beautiful C/2019 Y4 (or ATLAS Y4), a comet discovered on December 28 2019 that fragmented on April 9. Swiping left instead you can watch a little animation about the behaviour of the tail of a comet! - Credit:ATLAS, Wiki - #physics #astrophysics #solarsail #spacecraft #spacemission #esa #nasa #eso #solarsystem #earth #space #popularscience #popscience #popsci #science #comet #atlasy4 #atlas #comettail #radiationpressure #orbit #star #sun https://www.instagram.com/p/B-9NdB9pAIG/?igshid=utezxqisplpa

Testing Sunjammer, new Solar Sail by NASA

Testing Sunjammer Solar sail, it is a term defined by science fiction short story “Sunjammer” whose writer is Arthur C. Clarke in his 1964. In his story, he named Sunjammer is a method of powering small spacecraft without the use of an expensive propellant. It is a method for the propellant-free population and is quickly carving out space in the future of spaceflight. For testing a new type of solar sail system NASA has teamed up with NanoAvionics which run the mission by NASA’s Ames Research Center called Advanced Composite Solar Sail System (ACS3) in Silicon Valley. It is a small satellite move to low Earth orbit with a solar sail that unfolds around 800 square feet. The mission ASC3 will work to replace rocket propellants by developing and testing newly designed solar sails by using sunlight beams to give the nanosatellite velocity. NASA is an old technology, has thrown a solar test before in the year 2011. It is the second attempt of a flight test called Sunjammer that was canceled in 2014. The Planetary Society of Non-profit scientific organizations flew its own crowd-funded solar spacecraft last year. The NanoAvinic’s who have designed and constructed a 12U bus at its Columbia and according to research news Testing Sunjammer Solar Sail NASA. NASA’s Langley Research Center in Hampton, Virginia is also participating in the project. A Solar Sail is basically just like a sailing ship from the old clipper ships. You see in the movies but instead of the physical wind, a solar sail in space is a sail that reflects sunlight. People don’t realize as the light reflects from you it’s actually pushing on you and that’s because light doesn’t have rest mass but it does have momentum. When demonstrated, sun based sail innovation could empower a large group of adaptable space missions. Including flying a propelled space climate cautioning framework to all the more rapidly and precisely ready satellite administrators and utilities on Earth of geomagnetic storms brought about by coronal mass discharges from the sun. The innovation additionally could help expel a portion of the in excess of 8,000 bits of orbital dispatch refuse and jetsam ringing the planet. Lead station-keeping activities, or float at high scopes above Earth for correspondences and perception; and drive an assortment of fuels, profound space investigation, and gracefully shipping missions. They give a slight push to it. If you stick a light enough and big enough metallic sail near the sun, away from Earth’s gravity it’s going to move. The object gets closer to the sun, it gets a lot more push from a sail and if the object cut the distance in half, it will go half away toward the sun from the earth. From the initial push, the object moves faster than a rocket. The fact that light pushes objects has been known for quite some time but the fact that it could be used for propelling a spacecraft. It discovered until the Marine missions which were a bunch of probes in the 60s. F Brent Abbott CEO of NanoAvionics North America said: “I’m very happy & excited that NanoAvionics will be a part of Nasa’s effort. Eventually leading to more marvelous deep-space missions following the first interplanetary CubeSats Marco-A and B (Mars Cube One). The solar sail teamed up with NanoAvionics will build. Its system at new Columbia in Illinois with the final integration to be done under Nasa Ames facilities. Read the full article

The Astroknights

The Astroknights came about when I tried to combine the two coolest things: Astronauts and swords.

downloaded a new brush i really wanted to try out, so i did something for solarsail! i got him way back when i was a newbie from a friend and he’s one of my main coli fighters, but i don’t think i’ve ever actually drawn him in the 5+ years he’s been in my lair rip

left is his current appearance, right is what i’ve got planned and what i went off when drawing him

also fabric is still a nightmare to draw i don’t know how y’all pull it off

strange new worlds!!!

I watched the first seven episodes of strange new worlds and I'm here to TALK about them incoherently.

Look, after disco season 3 and picard season 2, I had basically had my heart broken twice. Make me love a show, make me bond with a crew, then fuck it all over with bad writing, poor decision making and shoddy showrunning.

Is it happening again??? oh, probably. But much as in 2017 when I was at rock bottom disco provided me with what I needed, in 2022 it did it again, just what I needed this time was some by the numbers star trek.

some of the perennial problems of modern trek are still present: characters have to have big secrets as well as tragic backstories. too many coincidences that just happen to tie into classic trek a little too evenly. However, a lot of that is excused: these are characters we know and they are connected.

I am very glad that this is it though, there isn't a big overriding mystery yet. Disco especially couldn't work out whether it wanted to be a show with a big mystery or lots of small mysteries and instead just piled mystery upon mystery until everyone was just suffocated.

I love the decisions that have been made: the gorn being the token scary baddies is a good choice. Fleshing out Spock and T'Pring's relationship is delicious, T'Pring is glorious. I'm waiting for her to ask Spock to fuck her like a human and how much that will bsod his brain to the point I will probably write it.

I ADORE Una and La'al. I didn't think I'd like La'al, mostly because I'm sick of everyone must be one degree of separation, but I love her so much. I love Una and Pike's relationship. I am BESOTTED with Chapel. Baby Uhura is adorable. Ortega is great. Hemmer is...you don't need me to spend ages talking about Andorians/Aenar because I read all those beta canon books (DRINK), just to say though I love him.

So far all seven episodes are great, probably the weakest was the pilot, though it was good. The commitment to self contained episodes and the old A/B plotting just is a reminder that the structure is a classic for a reason. Also, they did body swap!!! Body Swap and Enterprise Bingo! In one episode!

Quick reviews of each episode:

strange new worlds: pike's beard is awful, spock's body is incredible, light touch tie into disco, I miss Michael too, and a retconning of star trek history that would have been better coming before picard but that I'm still mildly annoyed about because it still doesn't really make sense to pretend that the diversion point between us and star trek is yet to happen but also not ugh just FINE BE THAT WAY.

children of the comet: could be mid-tier forgettable tng episode and I mean that as a compliment.

ghosts of illyria: echoes of tng episodes past collide with beta canon and two characters having secrets. genuinely loved this episode, una being illyrian is something I was annoyed was apparently changed but nah. Also discussing augments and eugenic war legacy oh my its like christmas.

memento mori: SO GOOD just so good. Ambushes! Gorns! Cat and mouse in space! Character development!!! Creepy shit!!! Hemmer!!! Creative uses for things!! Mind melds!!!

Spock Amok: BODY SWAP!!!!!!! ENTERPRISE BINGO!!!! Interesting diplomacy B plot! The solarsail ship! A definite great.

lift us where suffering can't reach: this is just an adaptation of 'those who walk away from omelas' but I am glad they did it, even if now the show is doomed to be sued by ursula k leguin for plagiarisms. but does her story have topless pike? no. so this episode is obviously the superior 'powered by a forsaken child' story.

the serene squall: shipbait and a great villain who overall sells a filler episode. good job. also: sybok!!!!!! the return of sarek: galaxy's worst dad maybe???

anyway this show is good I don't know why people aren't talking about it. also there's loads of kissing, absolutely loads of it. it didn't cure my depression but it did make me feel a bit better to lie in bed, watch star trek and eat crisps.

🇬🇧First English, a seguire in italiano! 🇮🇹 🇬🇧This is a period of anniversaries so I'm going to talk about Yuri Alekseyevich Gagarin (Юрий Гагарин). 51 years ago he was the first human to journey into outer space in his capsule: Vostok 1. He was a Soviet Air Force Pilot and was 34 when he completed his mission. What not many people know is that the mission with the Vostok 1 was his only one, even if he served as a backup crew to the Soyuz 1 mission, that ended in a tragic crash. His only flight lasted 1 hour and 48 minutes and gave him fame and success, bringing him to become deputy training director of the Cosmonaut Training Centre. The first picture in this post was taken by me in June 2019 at the London Science Museum, where there was an exhibition celebrating 50 years from the Moon Landing😊🚀🌕 🇮🇹 Oggi cade l'anniversario della missione Vostok 1, dove il cosmonauta Yuri Alekseyevich Gagarin passò 1 ora e 48 minuti orbitando nello spazio attorno la nostra bella Terra. Gagarin era un pilota dell'aviazione dell'Unione Sovietica 3 questa missione lo rese così famoso che fu la sua unica, anche se fu chiamato come membro di scorta per la missione, finita in tragedia, Soyuz 1. Infatti dopo la sua epica impresa fu chiamato ad addestrare al Centro Addestramento Cosmonauti fuori Mosca, che prese il suo nome in seguito alla sua morte. La prima foto del post è una foto che ho scattato io nel giugno scorso al Museo della Scienza di Londra. Infatti c'era una esibizione temporanea per celebrare i 50 anni dall'allunaggio 😊🚀🌕 #physics #astrophysics #solarsail #spacecraft #spacemission #esa #nasa #solarsystem #earth #space #popularscience #popscience #popsci #science #yurigagarin #firstcosmonaut #fka #rka #firstspacejourney #ЮрийГагарин https://www.instagram.com/p/B-39OdCJbAq/?igshid=tb9ufcvy7cc1

With Stephen Hawking as a board member, the Russian physicist billionaire Yuri Milner announced Project Breakthrough Starshot - a research and engineering initiative to launch a fleet of small satellites (called StarChips) to our nearest star systems. At a speed of about 15% the speed of light, Starchips would be able to reach the Centauri system (4.37 light years away) in about 30 years. These small probes could be powered by a multi-kilometer space based laser array system that would use photons to impart momentum on the Starchip’s solar sail. A mothership containing these small satellites is expected to be launched by around 2036. Thus, by 2070s, we may have extremely detailed information about possible habitable exoplanets such as Proxima Centauri b. .
