The US simulated the same way ;)

Do you have pictures/videos of it? I'd love to see more of those contraptions

I have a lot spreaded across my website https://wikiarchives.space

Here's the famous Walter Cronkite testing it ! https://www.wikiarchives.space/picture.php?/17430/category/2215

This one from your collection is amazing, given my interest in Bell #RocketBelt history.

Someone is wearing a #jetpack rig to explore flying or hopping under lunar gravity. It seems to be fed by the plumbing & pressure vessel in the background. There is water all over the place.

I know of paper studies for lunar backpack rocket devices, but nothing about hardware tests!

Bell did test a lunar rocket platform at Langley. LIFE took photos, and I once conversed with a pilot involved in this work.

WOW that's so smart 🤯

The transfer to the lander was off the scale

There any good reason why no recent lander missions have consider the "hold down jets"?

Bouncing indicates a rigid landing gear that responds elastically to a hard landing. Soft landing and energy dissipation in the gear obviates the need. Apollo had a crushable, aluminum honeycomb material in the gear that absorbed enegry; Armstrong landed so softly it didn't crush at all.

I didn't know that about Armstrong!

The LK Lander had some crushable material on the base of the footpads, this seems to have been removed for the LKM heavy advanced version.

You listen to the audio of the moonwalk, and he mentions the high step from the surface to the first rung. He tried it at the beginning to make sure it wasn't a problem later. They had expected it to be lower.

As Pete Conrad of Apollo 12 said, “Whoopee! Man, that may have been a small one for Neil, but that's a long one for me.”

Here's the transcript, from the Apollo 11 Lunar Surface Journal.

I don't know.

Given that one lander ended up upside down, it's not hard to see the value!
