One of the tweets said it’s cleaner than it started, by shaking off a fair amount of dust. I expected it would make its own cleaning events one...

Here are the questions I asked, four? five? six? Too many times to bother keeping track . . . including earlier today: ...

Who is that statement directed to? Because you certainly have not answered mine. There is no room for ambiguity, here - you haven’t come anywhere...

I hadn’t heard this before. From: https://www.bbc.com/news/science-environment-56799755 Ingenuity even carries a small swatch of fabric from...

Just a bit of a qualifier there: I believe the evidence is that most of the radiation coming from the Moon is due to secondaries produced by GCR...

Yes, well, I guess we can say “we were there at least as much as possible.” I get a kick that I was watching on my tablet (something that was...

Over now. This was historic enough to get me to stay up to watch. The first aircraft flight on another planet.

Now the view from Perseverance.

IT DID IT! First flight on another planet, I’m seeing its shadow on the surface.

I was thinking the same thing, and no doubt NASA teams have thought about it and modeled it, but Ingenuity is designed to be light and it does have...

:rofl: I know others have commented on this, but after all this discussion about the ubiquity of radioactive substances, I’m impressed and...

Ironic to see you saying that. A science article you provided showed you to be wrong, but you have yet to acknowledge it. You’ve been presented...

You most certainly did not! I even quoted that entire post in my response in #306. In fact, in #227 you claimed: You have not provided one bit...

Just a thought - there are now thirteen separate Director’s Keyboard threads, and they are weekly. Within a year there would be 52 more. They are...

Oh, they have considered it. There are tests of panel coatings that could electrostaticly repel dust, or drones much like Ingenuity that would hover...

Here’s three: ...

Any random bit of dirt *is* radioactive, because it *will* contain some radionuclides. From Wikipedia: ...

It does have blades that are to move at considerable speed to move a fair amount of the very thin atmosphere and it is supposed to move through the...

What’s really sad is I quoted from the Spence et al peer reviewed article (not NBC popular press stuff) that Lord Foul linked to in the first place...

Did you even read my first question in that post? You’re just repeating your “it’s radioactive” claim without qualification. That is meaningless....

I’m glad it works, but I’m not really that interested in suborbital. Get the passenger cost down to no more than $10,000 and I’d be willing to take...

I watched a YouTube video and learned a new word, the “onosecond.” That’s the second after you make a devastating typo or mistake (especially well...

Most of my questions involved your claims that you made without supporting evidence or calculations, focusing on your general claim that the Apollo...

I’m an American and I don’t recall ever hearing that joke. Makes sense, though. It really does look different from regular aircraft especially at...

I didn’t say I couldn’t. I even gave hints, it’s not like GCR has been a foreign subject in this thread. But this is something you should do,...

You’ve already been given links and information on GCR and mission radiation doses. Anyway, this is your CT thread, you are the one that claimed the...

I really don’t understand what Bezos is thinking. I’d like to see another nimble, innovative and hungry New Space competitor but Blue Origin feels...

First, are you claiming that a massive body like the Earth or the Moon could not block GCR? Because that would be utter nonsense. The practical...

Another important point from the Spence et al article linked above: https://agupubs.onlinelibrary.wiley.com/doi/10.1002/2013SW000995 Here is a...

What, in your opinion, is the relevance of this statement to the current discussion? I have some suspicions on how you might be interpreting it, but...
