I'm aware that the Russian language requirement is to be able to operate the Soyuz spacecraft on the ISS. Given NASA's plans to retire the ISS and the introduction of new spacecraft that don't require Russian for operation, will astronauts still need to learn Russian? Would learning Russian still be beneficial for someone aspiring to be an astronaut? Thanks!

Hello I received this pin from my grandmother, she said her father received it from NASA after working there for a number of years. I couldn’t find anything online and have been searching. He was working for nasa during the 60s through the 70s if that is any help at all.

Is there an official or authoritative program/ curriculum (structure) available how NASA (Nasa) astronauts learn Russian?

OTV vs OMV vs Space tug ....these terms seems to be used interchangeably. Do these space vehicles only differ on their payload mass capability?

Hi everyone,

I'm looking to make a CFD simulation of the Human Lander rocket nozzle. Is the nozzle profile available to us or is it top secret? I am a University Student. I just need the shapes of the inner bell wall and the combustion chamber. I don't need anything beyond that. Well, maybe some projected pressures and velocities. Thanks!

With so much interest in the upcoming solar Eclipse on April 8, we've decided to create this megathread to use as a focal point for discussions. Please use this thread instead of starting your own.

Hiiiiii, with the solar eclipse coming soon, I keep seing a lot of information about the phenomen, but there is an information that I keep reading and I'm not sure if I can trust it.

I know that you are not supposed to look at the eclipse without the proper equipment, but I've seen that it is okay to look at it with the naked eye when the eclipse is complete for like 1 minute since the color when it's complete is apparently magnificient.

Is it really safe or should I keep the pair of glasse on my eyes the whole time?

Thank you :D

How does the falcon 9 booster slow itself down so much that at landing, it always reaches 0 speed right as it touches the ground? is there some special math to this or just perfect timing?

Because of commercial crew they don't need the soyuz anymore, and spacex is cheaper than using the soyuz. In addition, spacex is american, and soyuz is russian. So why do NASA astronauts still go up on soyuz?

Hi all!

So, in waiting for the total solar eclipse event right around the corner...while I have myself a set of eclipse glasses, I was searching around the web for an answer regarding use of my Google pixel 8pro to take photos/videos of the event. And the answers are very conflicting to one another making me all the more confused and my questions still remains unanswered.

So can the phone be used as it is to take the photos/videos?, Will it damage the phone, Or will the phone be safe?, if it won't be safe, do I need to "special solar filter" for my phone too or will one of the the eclipse glasses I have be enough and do to trick?

2/3 articles and a person at my worksite said today's phones with their cameras don't need any such filter and r safe to use as they r and then there's the news of NASA releasing an app (sunsketcher, currently not available in Canada) to record videos of the event from phone...

But then there r articles claiming the direct opposite of this and saying the phone and/or the camera will be severely damaged because of the heat and infrared light. Even the instructions paper that came with the "Soluna 5 pack eclipse glasses" states not to use the glasses with another optical device during the event (but there is not specification as to which "devices" does it mean, does it mean cameras or does it mean eye shades/specks??)

I do have a tripod and a Nikon D3400 DSLR but I don't have a solar filter for the dSLR making me very hesitant to use it...

Please do let me know asap y'all!

Thanks and kindly 🙏🏼

--EDIT--

Just rediscovered that CBC (sciencenotes.org) article that's talking about using eclipse glasses as a filter for the phone to take the total solar eclipse photos and videos... https://www.cbc.ca/news/canada/total-solar-eclipse-phone-photos-2024-1.7149062 / https://sciencenotes.org/how-to-use-a-smart/ --> is this true??

I was inspired by the Neptune poster I posted about a few days ago, and wanted to make one over my favorite exoplanet! Let me know what you all think, and any ways to improve! This is my first attempt at making a poster, so it's definitely a learning experience.
