The /r/SpaceExploration Reading List

56 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

Full study: https://journals.sagepub.com/doi/10.1089/ast.2024.0165

Scientists have long assumed the Moon would quickly destroy most microbial stowaways. After all, it’s barren, lifeless rock for a reason. But a new NASA-led study is here to say: β€œNot so fast…”

Near the poles, craters and other terrain create patches of permanent or prolonged shadow, shielding microbes from the Sun’s lethal ultraviolet radiation. In some of these spots, Earth bacteria and fungi could remain alive for days, weeks, or potentially longer.

Now that’s a problem. Contamination could make it harder to distinguish pristine lunar chemistry from material humans introduced.

Yet if biological contamination cannot be eliminated, researchers argue that carefully tracking it could turn the Moon into an extraordinary experiment in how life survives beyond Earth.

They focused on five organisms likely to accompany humans into space: Bacillus subtilis, Staphylococcus aureus, the famously radiation-resistant Deinococcus radiodurans, several species of Fusarium fungi, and Aspergillus niger, a common fungus already found in bathrooms, HVAC systems, and even aboard the International Space Station.

The Moon’s poles offer very different conditions from the equatorial sites visited during Apollo. Because the Sun sits extremely low on the horizon there, crater walls and ridges cast long shadows. Some crater floors never receive direct sunlight at all.

I got stuck a few hours on this universe exploration website https://galaxium.app. I thought this subreddit might like it (mod sorry if not, please delete this post, this isn't my app at all).

It's like travelling from solar system planets up to the Milky Way and beyond. Was mind blowned on being able to travel between planets, moons, stars, and galaxies, and seeing satellites updates in real time.

πŸ§‘β€πŸ”¬ Science Missions best theoretical methods of propulsion for a long-term interstellar journey?

9 Upvotes

So I'm writing a sci-fi novel, I wouldn't say it's extremely "hard" sci-fi and I won't bore y'all with specifics but I want most of the science to at least hold up to a little bit of scrutiny. So I wanted to get some opinions/ideas of how the vessel could be propelled? It preferably needs to be renewable since the journey would take a long time (several generations by the time the story takes place). I've been heavily inspired by Andy Weir's body of work (particularly PHM and Artemis), the webcomic Space Boy by Stephen McCranie, with a few hints of the Starstruck universe (Lee & Kaluta).

I'm in sort of the beginning steps of writing and researching and I am doing my own research too but I thought I would ask reddit as well.

As a rule I've been trying to not get too hung up on the science but I really would like to have an answer to the question of propulsion. (And if anyone wants to give their two cents on how artificial gravity could work I'd be ever so thankful!!)

He was so eloquent, insightful, and inspiring -- the perfect person to command this mission.

Unfortunately, Rise was not there. The first thing Reid did after he sat down was explain that Rise is with Christina right now. The crowd was audibly disappointed.

Videos to follow in the comments.
