Got tired of the topic. Apollo 1 killed another 3. Tom Hanks was on 13.
NASA has too many old people who believe: Any landing you can ambulate away from (regardless of how fast you have to move) is a good landing and that it is a great landing if you can use the vehicle again.
Took a while...I get it. Good one!
I can spin with the best of them...
Lol.
This happened to the other lander too.
Coincidence? I think not!
Maybe it was the same moon monster that attack the Apollo 18 crew... : )

At least it won’t catch fire, no air.
When it comes to tipping over centre of gravity is a key concept. :)
The center of mass determines at what angle it would tip over, and that doesn’t change with gravity.
Or like Biden falling down the stairs.
When in doubt blame it on ALIENS.
Right. It didn’t make any sense to me.
Yes. The wonderful all-knowing media…./s
A big gust of wind got it. ... Oh, wait.
It snagged a rock or something. It is basically a success.
Almost doing what JPL/Hughes Surveyor 1 did on June 2, 1966 .
There you go with that STEM stuff again. What is importan is how they felt about it and that it was diverse and equal and that everybody was included in the plan. I suppose you also think engineering would have made some kind of difference for the Titan too? /s if needed.
I think that the 25,000 mph number is the velocity required to escape the earth’s gravitational pull and get to the moon. 25,000 mph is the initial velocity. You will decelerate after the final de-orbit burn due to the earth’s gravity and continue to decelerate until the moon’s gravitational pull is greater than the earth’s. The trick is to calculate what that point is and fall into lunar orbit at precisely the right velocity to require only a minor correction in velocity. Too fast and you will zip by and enter into an elliptical orbit (at best). Too slow and you crash into the moon.
Right you are. 17,500 mph achieves Earth orbit, and 25,000 mph escapes it.
The author of the article states that it takes 25,000 mph to escape the Moon’s gravitational pull. I don’t think that’s correct. I’m sure it’s much less. There are calculators online that will determine what it is, but in metric terms. I’m too lazy at the moment to figure it out in mph, lol. Math wasn’t my strong suit in school, but maybe later on I’ll take a crack at it.
My point was that the author, either through ignorance or carelessness, stated it wrong.
But don’t you agree that this craft should be shorter, thus the center of gravity closer to the moon’s surface?
