If a moon lander lands on the moon does it make a sound?

Question

"that giant leap so fragile that it hardly made a sound" --Walk on the Moon (By Great Big Sea)

My first thought was something like "there's no sound in space, dummy."

But then I realized (not a moment too soon) that when they landed it seems logical that there would be sound waves propagating through the air where the people were.

Am I right?

Would it be loud or soft?

Answer 1

The blasting rockets would be absolutely silent unless they hit your ear then you would hear a h**l of a roar.

Answer 2

There would be sound but only within the lander itself.  The surface of the Moon is almost a complete vacuum so sound waves would have no medium to travel through. The answer is no if you mean for someone on the surface watching a lander touch down.

Answer 3

The air inside the spacecraft could still propagate sound waves, yes. But after the landing, they waited a while to go outside so that they could finish up post-landing procedures. When they depressurized the lander, the air would have been far to tenuous outside (and constantly getting more so) to be able to hear anything.

Answer 4

Outside the spacecraft, no.  Sound waves can't travel through space.  But sound waves can still travel inside the spacecraft.
