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.

It's interesting to note that he was still on the pad when he delivered that line, while Armstrong's were actually delivered on the moon regolith. I suspect a few other "first words" were not actually delivered from the surface either.

Slavish dedication to metric units when Apollo used imperial units for everything 😏 its actually kind of jarring after listening to the flight loops

[@1pcfred]

The USA never used Imperial units. We used US Customary Units. They were developed by Thomas Jefferson in 1789 Our unit of length was actually based on what metric was supposed to be based on. But after Jefferson left the talks they changed it. Trans Atlantic communication back then was not too good either.

[@jeffvader811]

The flight computer ran off metric but converted to imperial for the Astronauts.

[@wrightmf]

Yes, how come they didn't use a folding ladder like the Soviets? Another item is it was a Grumman engineer in early 1960s that decided the commander and not the pilot be the first to step on the moon. Door was made to open inward, the engineer was right handed like most people. Because the guy on the right doesn't have enough room to climb over the door, it was the guy on the left.

Yes a hinging ladder or a ladder that had its bottom few rungs on a slide would have been easy solutions. I wonder why the rungs had to be so close together anyway.

[@feelingzhakkaas]

great video. Why ladder could not be telescopic? For the Apollo 12 and beyond...they could have made ladder longer.

[@Jan_Strzelecki]

A telescopic ladder would've been heavier than the non-telescopic one. Also, NASA had no guarantees that every other astronaut would land as gently as Armstrong did. And since it turned it to be a non-issue (both Aldrin and Armstrong could jump up the ladder), there was no reason to change the design.

Peter Conrad was referring to the studio in 1g, if they were really on the moon that's nothing in 1/6g. There is no indication of them being in 1/6g in any video, it's just slow motion video with the odd visible wire. There's just no height and all the movements are sluggish - it all just looks like a half speed video on earth.

Ok, I thought they removed two rungs to compensate for the weight of the flag and flagpole. Glad there was a better explanation :-)

Hi Tim, me again, can you do a video on the Dragon Capsule's parachutes? How do they work? Why are they attached on one side of the capsule and not on both sides? How do they open slowly? And the history behind of capsule parachutes...And so on...

[@Gibson99]

i second this - parachutes for returning space vehicles are a lot more complex than a skydiver's chutes. i remember seeing a documentary on Curiosity and how their chute testing was difficult and had lots of failed tests because it had to open at such high speeds though with a thinner atmosphere.

[@Wombattlr]

We need this video! I third this!

[@Gibson99]

Apparently SpaceX published a video of a Crew Dragon parachute test last night! kzbin.info/www/bejne/eGrIinZ9hNGla7s

[@StreuB1]

In the SpaceX Dragon video. If anyone is curious what the big black round things are on the "lines" near the Dragon capsule that the chutes are attached to. Those lines are called the risers and the "things" are called "riser guillotines" and they cut the risers in the event a main failure is sensed or they only have a partial deployment. They fire the riser guillotines to cut that chute assembly away and then fire the backup.

[@ernestosaboia]

@@StreuB1 Thanks for the explanation, I develop experimental model rockets and one of the most crucial and difficult part is the recovery system, hence my respect and admiration for the science behind it.
