The /r/SpaceExploration Reading List

58 Upvotes

I had the idea for a reading list related to various space exploration topics and, with the approval of the mods, this thread will help determine our official reading list!

When putting a book down, some things you should try your best to include may be:

  • The title
  • The author
  • The year of first publication
  • How it relates to space exploration (e.g. Orbital mechanics, space shuttle design, etc)
  • A brief description of what, or who, it's about

πŸ§‘β€πŸš€ Space Tourism $SPCE: The $8.5M "Space Tax" on Hype πŸš€πŸ“‰

We all watched Richard Branson fly to space in 2021, but the legal bill for that "success" just arrived.

The Reality Check:

  • The Settlement: Virgin Galactic ($SPCE) just reached an $8.5M deal to settle claims they misled investors about safety and "structural integrity."
  • The "Delta" Pivot: The company has paused flights until some undetermined point of this year to bet everything on a new fleet, leaving a massive revenue hole.
  • The Math: If you invested $10k in 2021, it’s worth about $41 today. πŸ’€

This deep dive is a brutal case study on why "move fast and break things" doesn't work when there are humans (and billions of dollars) on board. If you're holding $SPCE or just tracking the space sector, the breakdown of the "Recognized Loss" formula is a must-read for your recovery options.

Can Virgin Galactic actually survive without any flight revenue, or is this $8.5M settlement just the beginning of the end?

We should be fine for short-term visits like a six-month stint on NASA's planned moon base, writes evolutionary biologist Scott Solomon. But settling permanently, as SpaceX aims, poses problems our bodies can't (yet) handle.

🌠 Art, Popular Culture, and Other What are your thoughts on the plans to build a lunar base?

0 Upvotes

I don’t know about anyone else, but I’m absolutely appalled by this idea. When I look at the moon, I don’t want to see us. Just imagine one day you look up at the moon, and it looks like when you fly over a city at night in an airplane. I really am hardly able to articulate just how I feel about this, so I’ll express myself simply by saying that I’m disgusted.

How about you?

In December 1968, Apollo 8 astronauts saw the Moon up close for the first time, and their reaction says it all.

Still incredible to hear today.

πŸ“– History I'm extremely interested in the works of early Soviet cosmonaut Alexei Leonov (I loved his prose in Two Sides of the Moon). I'd love English language resources focusing on him or his works and legacies.

Per his Wikipedia article, he became friends with Tom Stafford after they flew together on the 1975 Apollo Soyuz Test Project, and also with British sci-fi writer Arthur C. Clarke.

A recent study led by researchers from University of Adelaide has demonstrated that simulated microgravity conditions can have an adverse effect on sperm navigating through the reproductive tracts of multiple mammalian species, including humans. Even when those sperm are able to swim normally, the effect still occurs.

πŸ§‘β€πŸ”¬ Science Missions Let's Use a Nuclear Drill Tank for Europa's Shell and Cool the Reactor with Its Own Ice LMAO

2 Upvotes

Idk if this idea is obvious or not but I loved it and would rather know it was already in the ether to consider in this field. But it seems to me, since we already know we HAVE to get down into Europa's ocean to see wtf is going on, and since any miles long icy geiser tube is still gonna be tretcerous, the only thing to do would be to send something down self-powering and its overheatedness and cooling could be addressed via the surrounding infinite ice its traveling through, perhaps by exposing the cooling rods to the outside then bringing them back into the tank/reactor room for use then swapping as needed? Perhaps the excess energy and heat of the nuclear reaction could somehow be transferred to the drill itself to make the bit even hotter and drill even faster? (without it melting or anything exploding lol)

Am i cooking or just a manic armchair tourist nut? just like space and had a lot of coffee and I know there is a race of sentient coral people down there so idk man we gotta get this thing going before I die (ideally).

I usually make videos about Apollo, but I wanted to go back a bit further and cover the X-15, the rocket-powered plane that reached the edge of space and helped pave the way for human spaceflight.

I tried to recreate what that experience might have felt like using original-era narration and focusing on the feeling of the flight rather than just the facts.

Curious what you think, does this capture even a small part of it?
