2024: Ham Radio in China, Soon Chinese Hams in Space

I’ve talked with Chinese hams during some of my overseas postings — as 7J6CBQ in Okinawa, Japan and as 7Q7DFC in Lilongwe, Malawi — though not yet from my home station in Virginia. During my ten years working as a US diplomat in the PRC I wasn’t able to get a ham license but did follow ham radio some in the pages of the Chinese electronics/radio magazine Wuxiandian (無綫電 Wireless) which had…

9 Out-of-This-World Moments for Space Communications & Navigation in 2023

How do astronauts and spacecraft communicate with Earth?

By using relay satellites and giant antennas around the globe! These tools are crucial to NASA’s space communications networks: the Near Space Network and the Deep Space Network, which bring back science and exploration data every day.

It’s been a great year for our space communications and navigation community, who work to maintain the networks and enhance NASA’s capabilities. Keep scrolling to learn more about our top nine moments.

The SpaceX Falcon 9 rocket carrying the Dragon spacecraft lifts off from Launch Complex 39A at NASA's Kennedy Space Center in Florida on Thursday, Nov. 9, 2023, on the company's 29th commercial resupply services mission for the agency to the International Space Station. Liftoff was at 8:28 p.m. EST.

1. In November, we launched a laser communications payload, known as ILLUMA-T, to the International Space Station. Now, ILLUMA-T and the Laser Communications Relay Demonstration (LCRD) are exchanging data and officially complete NASA’s first two-way, end-to-end laser relay system. Laser communications can send more data at once than traditional radio wave systems – think upgrading from dial-up to fiber optic internet. ILLUMA-T and LCRD are chatting at 1.2 gigabits per second (Gbps). At that rate, you could download an average movie in under a minute.

NASA’s InSight lander captured this selfie on Mars on April 24, 2022, the 1,211th Martian day, or sol, of the mission.

2. Data analyzed in 2023 from NASA’s retired InSight Mars lander provided new details about how fast the Red Planet rotates and how much it wobbles. Scientists leveraged InSight’s advanced radio technology, upgrades to the Deep Space Network, and radio signals to determine that Mars’ spin rate is increasing, while making the most precise measurements ever of Mars’ rotation.

3. We set a new high record! The TeraByte InfraRed Delivery (TBIRD) payload – also demonstrating laser communications like ILLUMA-T and LCRD – downlinked 4.8 terabytes of data at 200 Gbps in a single 5-minute pass. This is the highest data rate ever achieved by laser communications technology. To put it in perspective a single terabyte is the equivalent of about 500 hours of high-definition video.

4. This year we celebrated the Deep Space Network’s 60th anniversary. This international array of antennas located at three complexes in California, Spain, and Australia allow us to communicate with spacecraft at the Moon and beyond. Learn more about the Deep Space Network’s legacy and future advancements.

5. We are bringing humans to the Moon with Artemis missions. During expeditions, astronauts exploring the surface are going to need internet-like capabilities to talk to mission control, understand their routes, and ensure overall safety. The space comm and nav group is working with international partners and commercial companies to develop LunaNet, and in 2023, the team released Draft LunaNet Specification Version 5, furthering development.

The High-Rate Delay Tolerant Networking node launched to the International Space Station in November and will act as a high-speed path for data.

6. In addition to laser communications, ILLUMA-T on the International Space Station is also demonstrating high-rate delay/disruption tolerant networking (HDTN). The networking node is showcasing a high-speed data path and a store-and-forward technique. HDTN ensures data reaches its final destination and isn’t lost on its path due to a disruption or delay, which are frequent in the space environment.

The Communications Services Project (CSP) partners with commercial industry to provide networking options for future spaceflight missions.

7. The space comm and nav team is embracing the growing aerospace industry by partnering with commercial companies to provide multiple networking options for science and exploration missions. Throughout 2023, our commercialization groups engaged with over 110 companies through events, one-on-one meetings, forums, conferences, and more. Over the next decade, NASA plans to transition near-Earth services from government assets to commercial infrastructure.

Middle and high school students solve a coding experiment during NASA's Office of STEM Engagement App Development Challenge. 

8. Every year, NASA’s Office of STEM Engagement sponsors the App Development Challenge, wherein middle and high school students must solve a coding challenge. This year, student groups coded an application to visualize the Moon’s South Pole region and display information for navigating the Moon’s surface. Our space communications and navigation experts judged and interviewed students about their projects and the top teams visited NASA’s Johnson Space Center in Houston!

A SpaceX Falcon 9 rocket soars upward after liftoff at the pad at 3:27 a.m. EDT on Saturday, Aug. 26, from Kennedy Space Center’s Launch Complex 39A in Florida carrying NASA’s SpaceX Crew-7 crew members to the International Space Station. Aboard SpaceX’s Dragon spacecraft are NASA astronaut Jasmin Moghbeli, ESA (European Space Agency) astronaut Andreas Mogensen, JAXA (Japan Aerospace Exploration Agency) astronaut Satoshi Furukawa, and Roscosmos cosmonaut Konstantin Borisov.

9. The Near Space Network supported 19 launches in 2023! Launches included Commercial Crew flights to the International Space Station, science mission launches like XRISM and the SuperBIT balloon, and many more. Once in orbit, these satellites use Near Space Network antennas and relays to send their critical data to Earth. In 2023, the Near Space Network provided over 10 million minutes of communications support to missions in space.

Here’s to another year connecting Earth and space.

What are you wearing?

[rorybluez]

one of the joys of finishing children of time is a bunch of fans making sure to reply to almost every single "woah! Portia spiders are so intelligent" comment with an "allow me to introduce you to CoT books!!" and promote them with the vigour of a bachelor in marketing degree. You can nearly feel the overly enthusiastic desire to infodump behind their comments (tbh same). Shout-out to those meme spreading fellow spider fans, I salute you.

i cant post Tune without also posting Odyssey. do not separate.

Odyssey is an engineer, formerly the director of Mission Control, and before even that e did field work. Now, e’s supposedly retired from all duties, but Odyssey refuses to leave. E wont let the new owners run the team into the ground. (and e’s still holding onto some distant hope of finding es best friend alive, or at least closure)

-> Originally Odyssey was a field researcher alongside es queerplatonic partner Tune in their 20s, until the risks of such work became apparent. E then went on to develop systems to communicate with and coordinate the research team and monitor the Otherworld from safely on the ‘reality’ side of the portal. E established Mission Control, and led it for decades.

-> Tune and Odyssey were very close for a very long time, having met in their school years. They were best friends, partners for life, two halves of a whole. It’s been some years now since Tune’s disappearance, and Odyssey’s mostly come to terms with it, but still feels his absence keenly.

-> Odyssey’s a generally kind individual but not particularly nice. E’s gruff, immensely stubborn, with a mean sarcastic streak. Some coworkers might describe em as cantankerous. But at the end of the day e’s well-intentioned and altruistic.

-> Odyssey is very, VERY bitter about the investors who bought ownership of the team from the original founders a couple years back. E hates them. E’s just WAITING for the chance to prove there’s something unscrupulous happening, e can FEEL it. E hasn’t had results yet but the vibes are rancid.

-> Though formally retired, Odyssey continues to do much of the same work e’s been doing for decades, out of spite and because e trusts few people with the systems e built. E adamantly refuses to cooperate with anyone associated with the company, which is probably directly related to es early ‘retirement’. Odyssey’s not happy about it and won’t do them any favours.

-> Odyssey is only middle aged but e feels so much older. E’s so tired. And so worried. E hopes for the best but is always prepared for the worst.

-> Odyssey’s role as director was succeeded by Maven, who e mentored. Odyssey treats them as a ward and as a friend. E respects and trusts them, but…… When the Storm hit, it was one of Maven’s first missions directing with little input from Odyssey. It was supposed to be that, anyway, before that disaster. Odyssey doesn’t blame them for what happened, but but can’t seem to talk them out of beating themself up over it. Directing the EEG is no longer Odyssey’s job so e tries to step back and let Maven make their own decisions, but they’ve obviously not dealt well with the pressure, and Odyssey can’t leave well enough alone. E has a tendency to step in and take over es old duties at the first sign of trouble in a misguided attempt to shield Maven from the trauma of handling another crisis. E doesn’t mean to imply that they’re not capable, but unfortunately they are not helping Maven’s shattered confidence and fear of making mistakes by taking control from them.

-> Odyssey is legally blind, and though es glasses can help em make out some shapes in the right conditions, in unfamiliar spaces and bad lighting e utilizes a cane to get a feel for es surroundings. While es poor eyesight is likely hereditary, e became an amputee following a severe injury on es last field mission. E opts not to use any prosthetics, finding them uncomfortable and unwieldy. E’s often accompanied by one or both of the spider shaped robots e designed and programmed to assist the exploration team, which have been retired from the field as well since suffering some damage in the Storm. Odyssey is very fond of them.

-> The larger robot, Marie, was named after Odyssey’s cousin Mariner, who also worked for the EEG for a time. The two used to be close, but have had a falling out coinciding with Tune’s presumed death and Mariner’s retirement. Xe pushed for Odyssey to quit as well, but despite xer desperation xe wouldn’t confess why xe was so adamant about it.

-> The loss of Tune hit Odyssey very hard, and e’s become quite reclusive. E tends to stick to es room when not doing other work, and would spend a lot of time alone if not sought out by the other people who are close with em.

-> Spirit, Tune’s sibling, can probably best understand what Odyssey’s going though. The two have always gotten along well, having met through Tune. When Odyssey was injured, they requested Spirit join the team in es place, providing a glowing recommendation to the then owners. E’s always thought highly of Spirit, as a skilled and reliable member of the team (and someone e could trust to keep an eye on Tune where e couldn’t).

-> Spirit’s been different, recently. Odyssey has slowly tried opening up to them to talk about their shared loss, after es initial attempts to distance emself from the team in es grief. But any attempt seems stilted and awkward, so usually Odyssey never gets around to that part, and sticks to shallow small talk and talking At them about other problems. Honestly e just wants their company, and e feels they could use it, too. Odyssey worries for Spirit’s physical wellbeing in the Otherworld, and their mental wellbeing in the wake of losing their sibling. But they’re still capable of looking after themself, so e doesn’t push too hard. E just figures… well. Spirit probably needs the same kind of help e does, and e’s trying to be that for them.

-> If there’s a coworker that Odyssey really Does Not get along with, it’s Curiosity. In the past they’ve had a standard and respectful relationship. But with Tune M.I.A. and the EEG’s new ownership, Odyssey’s being phased out of the team though circumstance and es own actions and e’s feeling quite frustrated. E projects a lot of those frustrations into Curiosity, the new de facto leader of the field team and symbolic of the changes Odyssey rejects. Curiosity, for her part, isn’t keen on sitting around and taking flak from Odyssey.

-> Mostly they try to avoid each other, and that turns out fine. But when they do interact, Odyssey is… difficult about it. E will nitpick any plan of hers to test how it holds up, always double-checks her work, tries to pull rank/seniority regardless of relevance.. all in all, nothing malicious, but instead unreasonably hypercritical. E claims e’s only making sure she’s up to handle whatever the Otherworld throws at them next.

-> Phoenix on the other hand is a long time friend of Odyssey and Tune, having also met them through school before he dropped out. They’ve been a sturdy pillar of support for Odyssey through es grief, and regularly checks up on em to make sure es looking after emself. Though Phoenix, like Curiosity, is ambivalent about the new ownership, he is unlike Curiosity in that he is in good standing with Odyssey and is privy to sooo many rants about it. They talk often. Phoenix is really the only other person Odyssey trusts with maintaining the systems e built.

-> Phoenix and Odyssey had a brief romantic fling as young adults, which Odyssey now finds very amusing. Even moreso because Phoenix is kind of embarrassed about being ‘something of a headstrong dumbass’ at that age, in their own words. It’s one of the few things Odyssey and Curiosity (who also once dated Phoenix) can agree upon. It’s all in good fun.
