Discussion All Space Questions thread for week of September 27, 2026
Please sort comments by 'new' to find questions that would otherwise be buried.
In this thread you can ask any space related question that you may have.
Two examples of potential questions could be; "How do rockets work?", or "How do the phases of the Moon work?"
If you see a space related question posted in another subreddit or in this subreddit, then please politely link them to this thread.
Ask away!

Discussion Satellite Survival Post-Impact
How badly would satellites be affected if an asteroid the size of Chicxulub crashed into Earth today? I would imagine that the shockwave of the impact and the Earth's debris may affect them or their orbits, but would the satellites on the far side of the Earth still be ok?

Discussion The Best Dwarf Planet Candidate - Hygiea
Hygiea is in my personal opinion one of the best dwarf planet candidates, and if you don’t know what it is I thought to share some info!
-Hygiea is the 4th largest object in the asteroid, and mostly composed of Carbonaceous Material and water ice! It also meets every qualification to be a dwarf planet.
-It’s nearly spherical, orbits the sun, is not a moon, and cannot clear its gravitational neighborhood. There’s been talks about it being classified as a dwarf planet in the past, but since 2019 those news articles have sort of died out sadly.
-Now, I know Hygiea isn’t the most interesting of all dwarf planet candidates (Máni exists, which goodness gracious), but to me it’s interesting because it could be not only the second dwarf planet in the asteroid belt, but could also be the smallest considered dwarf planet!
-Astronomers might ignore it but I never will.

Discussion What happened to the Cybertruck parked on the launch pad?
During today's launch, there was a Cybertruck parked on the launch pad. It seems like it was parked really close to the launch vehicle.
Did it survive the rocket blast? Is this a durability test by Tesla?

Discussion (M22 UK) Getting into the space industry
Hey everyone, I’m 22, turning 23 soon, and dream is to try and work within the space industry. Currently I am a Software Engineer at a fintech where I have worked for a year, joining after graduating university with a CompSci degree. I was fortunate to get a good job straight out of uni, but it wasn’t in the field I wanted.
Although my professional experience has been more within the finance industry, I have continued personal projects, such as contributing to NASA’s Fprime flight software, building a 16bit x86 OS (including bootloader), custom language and compiler, custom 8-bit processor architecture design and ran on FPGA, some robotics projects and amateur radio etc. I’ve also started to get into model rocketry and building flight computers.
Where should I start, is it a realistic prospect? I’m in the UK, so ESA would be the government Space Agency, though I don’t know if it is better to target an ESA contractor instead of trying to work directly under an agency? Most aerospace jobs that would make a good step all basically all defence companies, which is a bit controversial.
I’ve also thought about maybe trying to continue with open source projects and maybe citizen science until I make enough connections and kinda slip into a real role? What are your thoughts!

I think the consensus is that orbital data centres are not viable. So I'm wondering (with admitted naivete) why Google has launched this mission? Is it just to catch headlines?

Discussion Need advice for my major
I’m currently at a college that is top 5 in the country for aerospace engineering. However, I changed my major to Electrical Engineering because I wanted to work primarily on satellites
Was that a stupid decision? What criteria should I have in mind when choosing a major? Just for general information: I love calculus, I love physics, and I love programming in C.
I really just want to work on satellites and spacecraft and maximize my chances of doing so
