By coincidence I'm doing all this NASA photo archive research stuff for a copywriting contract and this is bar far the BEST demo they've ever produced. They must have gotten the memo that they're PR sucks.
Originally David Attenborough made all the space noises but American audiences couldn't understand the accent so they tried using subtitles but the focus group thought they were alphabits and kept trying to eat them.
They ended up using sounds made by Oprah and Sigourney Weaver during a lesbian porn foley session.
Also that this clip isn't a TECH concept video, it's a "concept" video in the "this technology has been engineered, tested, the actual rovers and vehicles are built and loaded into a rocket and we've shot them into space yesterday and this is how it's supposed to work and it might look like this" sense.
