Why were there missing rungs on the Lunar Lander’s Ladder?

Something about the Apollo missions always confused me, sure, the step off of the lunar lander’s 91 cm footpad was a small step, but the step just before that was actually enormous!
I’m talking about this, the huge gap between the last rung on the ladder and the ground. Why on the Moon is that gap so huge?! Isn’t it dangerous to require an astronaut to jump down onto the surface and jump back up?
The lunar lander’s ladder had nine rungs all spaced 22.8 cm (9”) apart, but the gap between the last rung and the ground was about three times that at a whopping 76 cm (30”)! So really, the ladder wasn’t missing one rung, it was missing two!
I mean sure, the gravity’s only 1/6th that of Earth’s, but wouldn’t it have been so much safer if there was even one more rung to close that gap up a little?
So today we’re going to look into why NASA and the Lunar Lander’s manufacturer Grumman, chose a ladder of this length, we’ll talk about design considerations of the hardware, the unknown conditions of the lunar surface, and the astronauts who were basically too smooth of pilots to get the ladder’s last rung any closer to the surface of the moon.

Amazingly compelling evidence that man on moon landings were faked; amazing that the 3 astronauts that walked on the moon resigned a few days later.. all 3.. and then Neil Armstrong never spoke about it again, only giving a very cryptic interview about "uncovering truth" many years later. And the moon landing director resigned 3 days before they supposedly landed on the moon!

Apollo 17's time on the Moon also featured some singing & physical comedy, and it ended with a lovely speech and Mission Control nailing the shot of the lunar ascent from the rover camera.

Fascinating, I was wondering about hinged ladder - maybe NASA thought that might be something to go wrong (and maybe too heavy)

@samsignorelli 5 жыл бұрын

Perhaps a worry that it wouldn't deploy or that the hinge would fail and the lower half of the ladder would break off? There were so many unknowns that the simplest and least problematic solution would be the one to go with.

Aye! There's so much to learn about Apollo, I didn't know about the nozzle extension for Apollo 15, or that they considered using ropes to disembark. Sad thing is so many preliminary concepts and designs were never digitalised, and they live in the engineers attics gathering dust, I wish we could collect all the information together and put it in once place for safe keeping.

Ladders have been held short to make sure that even when tilting or eventual sinking into the moon will not affect the stability of the platform. And: saving weight everywhere is a factor as well. So, a bigger step down from the ladder could be afforded.

@Wombat1916 5 жыл бұрын

David Forbes In 1961 Arthur C. Clarke wrote a SF Story "A Fall of Moondust" where it was postulated there were patches of VERY deep dust, based on the studies of dust descending from space. YECs said it proved the Universe was young! However, careful examination of the experiments carried out shewed that much of the dust was terrestrial in origin and that there was little from space - hence not so much on the Moon either.

@animistchannel2983 5 жыл бұрын

At the time, prospective micrometeor & dust accumulation calculations suggested that the moon could be covered in an average of several meters of fluffy, almost liquid-like powder. I think it was Robert Heinlein who even wrote a story based on it, describing dust-pits and avalanches that could pour across the surface to bury or otherwise cripple vehicles, or lure a driver into a deep fall into a crater. When the moon turned out to be much more bare, scientists had to go back to the drawing board on the matter, and a different theory/mechanism of surface dynamics emerged as the best. Of course, for years, the Young Earth Creationists were touting the lesser amount of dust as proof that the moon was only 6000 years old...
