I'm no expert, but Mars' thin atmosphere (which is less than 1% of earth's) would make even a tiny gun effective. This would also mean that the gun would need to be able to handle the pressure, so maybe it wouldn't really effect the weight. But what are the weight requirements on this...

I have heard of them(I forgot about Polaris Dawn 3 using a Starship, though). Artemis also depends on it, but they only need Starship as a spacecraft, not a launch vehicle. I'll admit that I don't know exactly how this is regulated, but they might only certify the upper stage. Artemis plans on...

I remember hearing NASA only gave Boeing more because they asked for more, and that SpaceX said that if they knew Boeing would ask for so much, then they would have asked for more. An interview from 5 months ago says that the crewed version of Dream Chaser won't be inside the fairing. I'm...

New Glen is a launch vehicle. Dream Chaser, Starship, and Orion are the only other American orbital crew capsules in development that I know of. I don't think Starship will be crew-rated anytime soon (If ever), and Orion might be used exclusively for the Artemis program. I'm excited for Dream...

I don't think we're missing the point. Half of the problem is detecting the meteoroid early enough, and the other half is dealing with it. I think it's easier, and more fun, to talk about dealing with it. You're right about the detection being very important, though. By the time we detected...

If such a laser can be reasonably built, then I think it'd be the better solution. But I don't know whether that's the case. I think DART and Starlink prove that the impactor method is practical, though. Assuming Wikipedia is right, and all Starlink satellites are V1, then SpaceX has deployed a...

The primary constrain with deflecting meteoroids seems to be time. If NASA had a 10-year warning, then there's no doubt in my mind that we would find a solution with current technology. IDK if it's sufficient, but We already have a system to track meteoroids. So what should our Earth Meteoroid...

The forums (or are they sub-forums?) "Our Solar System", "Cosmology", "Space Travel & SpaceX", "International Space Station", and "Telescopes, Star Charts, & Planetariums" lack text when you hover over them. I had to web search what cosmology was because there wasn't hover-text saying "The...

I do not "love reminding folks of the rules.", but I will point out when a conversation I'm having begins to drift from the topic, e.g., right now. I'll also preemptively point out when one of my posts might lead to political debate, because some people get political quickly, and it might be a...

This is an awesome success, but there was only 51.2 g inside the capsule? If it was only the stuff inside, then this mission wouldn't meet their 60 g hopes. Was this because the sample was a finer grain than expected? If all went to plan, then would they have gotten what they wanted? Did they...

I apologize. I didn't mean that everything you two posted in this thread was part of the "useless small circle of argument". I was just pointing out the repetition in #54, #59, #60, and #62. When I said cost, I meant "A negative consequence or loss that occurs or is required to occur.", not...

I can't wait for a spacecraft to pull an Opportunity, and operate long after its initial mission. Let's just hope it doesn't also pull an OSIRIS-APEX, and rename itself every time it gets a new objective.

I don't understand half of your posts. I'm assuming English isn't your first language. My meaning is that billslugg and arturo.v.dominguez@gmail. were uselessly arguing in a small circle. billslugg would say "space is too slow/expensive, conventional means are the best solution, at least in the...

I assume you're clarifying post #30:

Image you had a jar full of infinite money, and you're dangling over a fire by a thread. Do you open the jar first, or save your own life? No one here thinks that human spaceflight is useless. What I think billslugg is saying is that we can't realistically solve our problems with spaceflight in...
