It just seems worth saying, and I hope it doesn't come across as too preachy, but the astronauts servicing Hubble are literally risking their lives, from the moment they climb on top of the world's most powerful rocket, through the spacewalks, and back to Earth, and all of humanity owes them thanks for the risks they're taking to advance our understanding of the universe.
It's pretty amazing that there are people who are not only willing, but excited and proud, to put their lives on the line for science and discovery. This isn't like working on a terrestrial telescope. This is life and death for people with families and friends and communities and a thousand meaningful connections. They're putting that all on the line so that we can advance as a civilization and I'm deeply thankful.
Thank you. You're appreciated.
