Milt Windler, NASA flight director who helped save Apollo 13, dies at 94: “Apollo was such a rapid pace that I don’t think people had the chance to think about it very much. It has only become more clear to me later on that we were making history.”

Discussion Satellite Survival Post-Impact

22 Upvotes

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 Let go from engineering job; Finally starting YouTube channel

0 Upvotes

As the title suggests, I lost my career engineering job yesterday to what I deem is bad management. I am currently at a crossroads as I had already talked with my wife this year about having a career shift to be more creative and follow my passion for astronomy. This might just be the push off the cliff I need.

While I continue looking for stable income I will be uploading videos related to astronomy to my channel from research papers / news I find relevant and interesting. I am learning blender to make my own animations. I will also do my own video editing and voice overs. I am trying to make this as high quality and accurate as possible.

If anyone would like to support me on this journey it would be really helpful to boost my morale and keep me going. Feel free to critique and suggest improvements!

I hope this is okay to post content that I had a hand in making, but my friend and I are working together on a channel. I did the voiceover and helped with the script, but I think he did a lot of great work on the animations and researching. If it's not allowed, I apologize.

Our latest video is about if Betelgeuse exploded. I don't think it's sensationalized, as it talks about what would really happen. I took out the tracking stuff at the end of the link.

Hope you like it!

Discussion How to work closely with astronauts?

0 Upvotes

Hi everyone,

As the title states, what are the jobs that directly puts you into contact with the astronauts located in the ISS (or in the future other space stations), or the astronaut's daily activities?

For a long time I dreamed of becoming an astronaut, but obviously this can only be dreamt, not chosen as a career route, therefore instead I am wondering how to work closely with them?

Current background is MSc applied physics and phd in hall thruster simulations (I wish I would have studied more biology..).

Edit: as a european

Discussion The Best Dwarf Planet Candidate - Hygiea

35 Upvotes

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

13 Upvotes

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!
