That has to be the coolest promotional video ever produced by NASA. The Battlestar Galactica style camera work. The sound of the wind whistling over the Martian plains. Just fantastic.

We were talking about how to interest people in space exploration? This is it, my friends.

Actually it seems like they've added on 20 seconds to the end.

Speaking of cool, Mars and the Bowie classic always works well:



That's a personal thing I have about videos like this. General public need something they know before they'll even bother watching videos like the MSL one.

This linked video has 33,000 views and I bet 90 percent of those views weren't people searching for Mars Rovers.

I know its juvenile but I just love the laser at the end :D

The whole thing is very cool. MSL looks like an all round larger more capable vehicle than the MER's, but still based on the obviously proven and robust MER tech. Still, watching all those moving parts in that dusty environment makes me nervous.

There seems to be several versions of the video, the longest seems to be 7 1/2 mins with a rock core sample being taken and analysed at the end.

That is definitely a neat video. Well synched to the lyrics. If I had made it, though, I would have cut off the song before the second half. It definitely becomes a lot more downbeat there and I don't think that's the message the creator wanted to send...

I take your point about needing something to entice people to watch the video. However, you also have to offer them a certain amount of information once you have the eyeballs there. Someone watching the Bowie video might not necessarily know that it was showing real probes at the beginning, what stage of development they were in, who was launching them etc. The video mixes reality and fantasy, which is great for viewers like us, but if you're hoping to do publicity for NASA then you have to offer a little more.

It's cool to see how this gets to the surface. Any reason why they aren't bouncing this one with airbags?

Too big.  MER was near the limit of the airbag method

Too heavy. Airbags don't scale up well. Pathfinder was small enough to use airbags alone, but even the MERs required some rocket braking.

Great piece of kit. Have NASA/JPL produced any comprehensive presentations on the MSL?

Wow.  That was a lot more detailed than the video from a few months ago.  All that ChemMin sampling stuff looks very prone to failure.  Good stuff.  I can't wait to see this thing fly.

Not really - other than what's at the MSL web pages. The rover still hasn't been fully built or tested yet, and they're still fine-tuning the descent stage design (including the 'skycrane maneuver' hardware); also, JPL/MSL folks still have to finalize their landing location (because MRO is still taking full detailed images of the large # of proposed MSL landing sites).

The period after aeroshell release with crane and rover under retros looks particularly dicey, especially with weight/COG issues due to combined vehicles. Not to mention the hover/repell maneuver. Bravo to software program designers if they pull this off.

That is really impressive...and it looks like a much more complex landing than MER.

By the way, not to hijack the thread...are the MERs still chugging along? (I haven't heard anything that said they died)

Propery "descent stage and rover"

I can't wait for the documentary on PBS (in HD, of course) showing the testing.

I wonder how well the crane can hover in a strong crosswind.
