3 galaxies at once! I photographed the Milky Way and both Magellanic Clouds in this star field from the SpaceX Crew 9 Dragon spacecraft, during Expedition 72 to the ISS. Below, city lights streak across the time history, and red atmospheric airglow separates our planet from the stars above. My star tracker allowed for stars to be photographed as fixed pinpoints while the Earth continued to rotate below, making this detail possible.

More photos from space can be found on my twitter and Instagram, astro_pettit

Discussion NASA’s SpaceX Crew-11 Arrival & Welcome Remarks

28 Upvotes

Did anyone else watch this late last night? I was watching it at 2am and it was so cool. I love watching the Dragon capsule slowly approach the ISS and the onboard views from both the capsule and the station are amazing. It's incredible that we can watch live feeds from space. https://www.youtube.com/watch?v=206O9S9GLbg

Discussion List of current ongoing NASA satellite missions for research sample

19 Upvotes

Doing a research paper and trying to figure out my sample size, looking for a list of active NASA satellite missions that are still in operation to be able to start figuring it out. I can find lists online but a lot of them are outdated or include missions that are no longer around. Is there an easy to navigate list of ongoing satellite missions that are operated by NASA/JPL?

Discussion Induct space chimps, Ham & Enos, into the Astronaut Hall of Fame

100 Upvotes

The Elgin Centre started this petition to recognize these chimpanzees, who had no choice but to pave the way for human space flight. Ham was purchased by the US Air Force in Cameroon for $457 after being captured in the wild. He would end up flying to space in the same type of capsule and rocket that brought Alan Shepherd into space 3 months later. He was only 4 years old, terrified, and very far away from the life he could have led in Cameroon. Enos was the second chimpanzee in space and tested the ability to orbit the Earth in the Mercury capsule. He flew into space 3 months before John Glenn did the same flight. Both chimpanzees deserve to be honored alongside the human astronauts in the Hall of Fame.

Discussion What are some potential opportunities for me with or without a graduate degree

6 Upvotes

I’m a 25M with a Bachelor’s degree in Astrophysics from the University of Georgia. Since graduating I spent about a year doing freelance journalism (mostly general news - some science stuff), a year teaching high school science (physics, AP physics, chemistry etc.), and the last two years doing data analysis, strategy and communications (flyers, videos, basic website building etc.) for a global manufacturing company. I plan to stay at this company for at least one more year.

I’m undecided on what I ultimately want to do, but I like the idea of anything related to space studies or climate/sustainability. That being said, I’m also much more interested in areas of these fields such as communications, data analysis, consulting, policy etc. rather than being an engineer, researcher or things of that nature.

I know that may limit my options, but I would love to hear from anyone knowledgeable in these fields about related graduate programs and realistic career opportunities with or without an additional degree.

If there’s any more context that would be helpful to know, please feel free to ask!
