back to article NASA unveils eye-popping molten moon and luna tour videos

NASA has released two videos to celebrate the 1,000th operational day of its Lunar Reconnaissance Orbiter (LRO). The first vid, dubbed "Evolution of the Moon," traces the likely origin of the Moon, starting around 4.5 billion years ago when it is thought a chunk of Earth was knocked into orbit after a major collision. The Moon …

    NASA in the first video ...

    seems to be admitting that sound travels in space with all the crashing sounds ..

    "The first vid, dubbed "Evolution of the Moon," traces the likely origin of the Moon, starting around 4.5 billion years ago when it is thought a chunk of Earth was knocked into orbit after a major collision."

    the video does in no way show that origin .. did the author actually watch the video which starts at the cooling phase of a well formed round moon and shows nothing to indicate it's earthly origins, nor, really, anything about the moon's origins ?

      I, too, had been hoping for a moon-formation aspect, with a nice big chunk of Earth being knocked free into orbit.

      The sound effects add a nice bit of drama to it, IMHO.

      Since impact ejecta can often travel vast distances, I wonder what it might *really* sound like as fine-grain debris thumps into a microphone. Speeded up massively, of course, like the video itself.

      Animations like this rarely show how things might appear in real time because, although asteroids can move fast, 20 or 30 miles a second, on the scale of something as large as the Moon, the apparent motion would appear quite a lot slower than watching a second hand moving around the perimeter of a watch face.

      There is considerable debate as to the detailed mechanics of the Moon's very early origin. The video is reporting on what is pretty much known for sure.

    Nimoy

    I really wanted it to be Nimoy's vocals on this video when it started....

      In the middle of the moon

      In a land born in fire

      Lives a brave little hobbit

      Whom we all admire

      With his long wooden pipe

      And his fuzzy woolly toes

      He lives in a hobbit hole

      And LRO sees him

    Sound in space

    Contrary to popular belief space is not enough of a vacuum to _totally_ prevent sound propagation. Look it up.
