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.

What if you could launch normally, but when you separate the final stage, what if you left the liquid O2 tank, but with things added? You could then unpack things into the tank and connect it to the crew area and use it as lots of extra space. Would that work? If not, tell me why.

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?

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?

Hi, I am part of a high school team doing a tech demo of the accuracy of an STM32U5 microcontroller's peripherals. We only wanna test the relevant ones, though. We noticed that STM32U5 has the Serial Audio Interface (SAI). But, one thing to note is that there is no natural sound in space. Not sure if it can operate in a vacuum either. Sure, there's sonification to consider, and maybe some stuff with radio communication systems. Though another thing to note is that if STM32U5 was ever used in space - it would probably only be for simple missions - and I'm pretty sure most simple missions wouldn't involve audio. Also not sure if SAI would be good enough in general for audio in space. So my main question is - would it be worth it to demo STM32U5's SAI interface in our in-orbit tech demo? Any insights, especially with scientific explanations or linked resources would be greatly appreciated. Thanks!

It’s a JAXA-ESA phobos lander and sample return launching THIS MONTH. if it works this’ll be the first phobos lander and the furthest ever rock samples

I know the picture is a little grainy, it was an enlarged picture from who knows when. The thrift store was in Jacksonville FL. I know it's super close to Kennedy Space Center.

Disclosure: I’m involved with Scienshell, and this question grew out of a film project about future space infrastructure. For a realistic cislunar-to-deep-space transportation network, which should come first: a propellant depot, a repair-and-resupply station, or a crewed transfer habitat? What near-term missions would justify it, and which bottleneck—propellant, power, docking, maintenance, or traffic volume—should determine its location?
