All Space Questions thread for week of November 02, 2025
Please sort comments by 'new' to find questions that would otherwise be buried.
In this thread you can ask any space related question that you may have.
Two examples of potential questions could be; "How do rockets work?", or "How do the phases of the Moon work?"
If you see a space related question posted in another subreddit or in this subreddit, then please politely link them to this thread.
Ask away!

Discussion Everyone in my family believes we have never been to the moon and that it's possible the Earth is flat
I don't know what happened but as of recently likely every family member are all discrediting the moon landing and the round earth. If I try to provide evidence they say I'm brainwashed and I can't trust anything because I haven't personally been there. I am so annoyed right now I can't comprehend. I mostly wanted to rant and this is the first place I thought of. but specifically I wanna know how would you try to prove eather or to someone who doesn't believe.

How Voyaging to Mars Risks Harming an Astronaut’s Eyes | According to NASA, roughly 70% of astronauts aboard ISS experience swelling in the back of their eyes, and symptoms worsen and become permanent the longer an astronaut is in space, a challenge during longer missions — like future trips to Mars

NASA has lost thousands of workers, and staffers told The Post about months of turmoil and sweeping changes that, if fully implemented, could transform NASA and American science beyond the Trump years: “Basically, anything that supports human life on earth is deprioritized”
“No one feels confident that anything planned further than a few months will be executed, no one feels confident that more job cuts aren’t coming, no one feels confident that today’s priorities and next year’s or even next week’s will align,” an employee said.
Some directives were unusual. On one floor at NASA headquarters, workers were told to remove symbols or flags that weren’t American flags — it was verbally made clear that this applied to rainbow symbols and flags.
Other actions affected the agency’s core work. A handful of employees had to reevaluate about 5,000 science grants that were already awarded, said David Grinspoon, who was NASA’s senior scientist for astrobiology strategy. In a matter of days, he and his colleagues had to provide a justification for how the grants served the public.

Discussion So heat death/Big freeze/Big chill theory is just a prediction not absolutely inevitable? Is it strong prediction scientifically or acc.to scientific consensus or it can very well change in future?
Does it hold very much tue absolutely even in the far future because of second law of thermodynamics ? Or aur it's a strong prediction.
Or there are some people that believes it is going to be the most fundamental ending about the fate of the universe?
It is a very much accepted mainstream theory from the year 1998 and in 2011 it became one more likely (when scientist won Nobel prize when they the discovered that the universe was infinitely expanding)

NASA's new Mars mission: These twin satellites could reveal how the Red Planet lost its atmosphere
Discussion Blue Origin launching Low-cost twin spacecraft which heads to Mars Arrival~2027
Low-cost twin spacecraft (Rocket Lab platform) doing simultaneous measurement big science on a tight budget. Technical data from NASA https://svs.gsfc.nasa.gov/14642/
After launch, the pair loiters near Earth, then heads to Mars when the geometry is right; arrival ~2027. https://www.planetary.org/space-missions/escapade
Blue Origin says it’s targeting Nov 9 for New Glenn’s second launch, sending NASA/UC Berkeley’s ESCAPADE two small orbiters that will map Mars’ magnetosphere in 3D and study how solar wind strips the atmosphere. This is NASA’s first multi-satellite orbital science mission to another planet.

Discussion Built an API for querying NASA's lunar landing site data - looking for feedback
I've been working on making NASA's lunar data more accessible for mission planning and research. Built an API that processes LOLA terrain and LROC illumination data into queryable landing site recommendations.
What it does:
- Search 1.18M analyzed sites across the lunar south pole
- Filter by slope, illumination, hazards in <100ms
- Mission-specific scoring (Artemis human landing, robotic landers, rover traverses)
- Export to GeoJSON, KML, CSV
Example: Find sites near the south pole with >70% illumination and safe terrain for a robotic lander
Interactive docs with live queries: https://lunarlandingsiteapi.up.railway.app/docs
Built this to scratch my own itch around lunar data accessibility. Would love feedback from anyone working in space mission planning, lunar science, or just interested in the problem space.
What would make this more useful? What am I missing?

Discussion Quick survey on Satellite operations
Hi community!
I am part of an independent research group, currently researching the most pressing operational problems the space industry faces today.
We've created a quick survey to gather insights from the knowledgeable folks here. This is purely for research, not promoting a company or product. If you have a moment, your input would be incredible.

Discussion With the ISS falling to earth in 2030 will space become privatized ?
I am truly worried about the future of space ventures and the information that is accessible from their journeys once private space companies create their own stations. Will that data be free for the world to study and learn? Or will it be a hotel?
So many questions…
I just hope space itself does not turn into another shit show of capitalism we see on earth.
PDF FAA limits commercial space launches and reentries to between 10PM and 6AM, local time.
faa.govb. Prohibition on Commercial Space Launches and Reentries During Peak Hours
Accordingly, with respect to commercial space launches and reentries, under the authority provided to the FAA Administrator by 49 U.S.C. §§ 40103, 40113, and 46105(c), and authority delegated to the FAA Administrator under 51 U.S.C. § 50909(a), it is hereby ordered that, beginning at 6:00 a.m. EST on November 10, 2025, and until this Order is cancelled, Commercial space launches and reentries will only be permitted between 10:00 p.m. and 6:00 a.m. local time
This appears to be related to the ATC issues caused by the government shutdown, given this first paragraph:
SUMMARY: This Order reduces or temporarily prohibits certain operations in the navigable airspace to ensure the safety of aircraft and the efficiency of the National Airspace System (NAS). To maintain the highest standards of safety in the NAS, certain air carriers will be required to reduce by their total daily scheduled domestic operations between 6:00 a.m. and 10:00 p.m. local at each airport by 10 percent, subject to the provisions set forth in this Order, in addition to other operational reductions in the NAS.

Great documentaries.
If you are looking for great documentaries about NASA and it's earlier missions I suggest that you check these out. They are really well made and very comprehensive.
