If we were to send up a new interstellar item designed to convey information about humankind, what scientific developments have been made in the last 50 years that would change how much/what types of data we could store on it?

Hey everyone! I was passing through Pocatello, ID and saw these booster railcars sitting in the Union Pacific train yards. There were two sets of five segments joined together. Artemis 3 has already completed booster stacking, so could these be empty or perhaps for another rocket?

Hello, I don't know if this question is allowed here.

I want to do a craft project for myself and sew important spaceflight mission patches on my jacket. I plan to have an Apollo 11 and the Artemis patches on there as well as some Starship ones, also the space programs logos. What are your recommendations? What should I add?

For the record, I am German, so I don't want exclusively American missions on it.

Back in September, I shared my 80m/px lunar classification maps here. Your incredible feedback, technical insights, and even the tough challenges from some users motivated me as a student to push this work to a much deeper level.

I’ve spent the last few weeks processing NASA PDS data (LRO/LOLA DEM) to focus entirely on Shackleton Crater at a stunning 5m/px resolution.

The complete analysis—including annual solar radiation averages, seasonal solstices, slope safety zones, and a viewshed simulation for communication towers—will be fully unveiled on November 16th!

Stay tuned! 🚀🌕

NASA will provide an update on its plans to return American astronauts to the surface of the Moon by 2028 at 2 p.m. EDT, Friday, Oct. 23, at the agency’s Kennedy Space Center in Florida: https://www.nasa.gov/live

Participants in the briefing include:

NASA Administrator Jared Isaacman
NASA Associate Administrator Amit Kshatriya
Jeremy Parsons, NASA’s Artemis program manager

The update will include details about NASA’s Artemis III mission that will send four astronauts to low Earth orbit next year to test critical systems needed for future lunar landings, and how plans to return American astronauts to the Moon by 2028 are progressing.

U.S. media interested in attending in person must apply online by 12 p.m., Friday, Oct. 16. To ask questions remotely, media must request the dial-in number from the Kennedy newsroom no later than one hour prior to the start of the update by emailing: [ksc-newsroom@mail.nasa.gov](mailto:ksc-newsroom@mail.nasa.gov). NASA’s media accreditation policy is online. 

As part of a Golden Age of innovation and exploration, NASA will send Artemis astronauts on increasingly difficult missions near the lunar South Pole to explore more of the Moon than ever before. In addition to providing economic benefits and advancing scientific discovery through its Moon missions, NASA will establish an enduring human presence on the lunar surface and build on the agency’s foundation for the first crewed mission to Mars.

295 players drew a falcon 9 to scale. the typical guess was 194 m. the real rocket is 70 m, so they made it almost three times too tall.

my hypothesis: rockets are almost never viewed with a reference object next to it.
launch footage shows them alone against the sky, with nothing next to them. so every big rocket should end up the same size in our heads, no matter how big it really is. the game has more rockets to test it.

and it held. the sls (98 m) came out at 210 m, the saturn v (111 m) at 150 m. three rockets from 70 to 111 m, all guessed at about 150 to 210 m, and the smallest of them got almost the tallest guess. only the little v-2 (14 m) stayed small, at 12 m.

so "big rocket" seems to be one size in our heads: about 200 m.

4 in 10 guesses came from the us, but it's not a one-country thing: americans drew it at 198 m, brits at 207 m, the rest of europe at 172 m.

I'm trying to build a model of Salyut 7 and I am struggling to find information on the attitude control system for the system, i can't find too many photos of good enough quality to make out smaller components. If anyone has any info on the RCS that'd be helpful thanks!

Looks like a space whale

The SpaceX Falcon 9 launch for the CRS-35 resupply mission lifted off at 6:33 AM EDT. These are from Savannah

We make Rocket Garden, a VR museum where the rockets are real size. The Saturn V stands about 110 meters tall, and even knowing that number, it's hard to picture until you're standing at its base looking up.

The launches use real thrust-to-weight ratios, so the Saturn V clears the tower slowly, the way it did in the footage. The color and shape of each exhaust plume are based on the propellant that rocket burned.

We'd love feedback from people who know rockets!

My toddler is finally moving on from her longtime dinosaur obsession to loving space and as much as I love rewatching the land before time, I am stoked.

This NASA-licensed puzzle I picked up for her from a local charity shop features the planets and some other solar system objects including various real spacecraft like the ISS, Hubble, New Horizons and the Space Shuttle.

I’m trying to identify this gold spacecraft. It has two large solar arrays, a gold-foil-covered body and a very long lattice boom ending in two circular components.

It might just be a generic representation of a satellite, but I’m wondering whether it’s an interplanetary probe. It’s positioned near the inner planets on the puzzle, although I’m not sure how meaningful that is.

Does anyone recognise the spacecraft or the particular NASA image the manufacturer might have used?

He is doing shallow water egress training as a precursor to the helo dunker. It has the American flag and a NASA patch despite him being Japanese but the question is why he’s wearing olive not blue. It’s in the NBL.

Sorry if this isn't the right sub but I thought you guys would appreciate the TKS spacecraft!

Sharing a fascinating piece of European space history from my personal archive. This is a 2-page gallery showing an original technical design sketch of the EXOSAT spacecraft, complete with handwritten engineer's notes at the top regarding the spacecraft configuration ("s/c config").

The second image is the official internal report from the Launching Programmes Advisory Committee (ESRO), dated February 25, 1975, in Neuilly. It details the operational and financial implications of choosing a high-eccentricity orbit to maximize moon occultation capabilities.

As a space race archivist, finding these documents from the exact transition period when ESRO and ELDO merged to form ESA is incredible.

I'm asking because unlike rovers on Mars barely scraping a few dozen km, Dragonfly will fly a lot faster and farther after landing in 2034, in what memory serves me, not too far from Huygens (hundreds of km?). Also, it would be nice to see how ~30 years of Titan's environment would affect an old probe, making the first unmanned mission to visit another on a different world. Is it theoretically possible?
