How to bring a 3.3 tonne laboratory from 21,240km/h to zero in 7 minutes... - Page 15

I studied first year physics at uni so I know what I'm talking about - you can bring a 3.3 tonne laboratory from 21,240km/h to a complete stop by firing a 3.3 tonne laboratory at it at 21,240km/h in the opposite direction.

Yeah they did that, theres a 2nd rover just hovering somewhere

Wouldn't they then impart their energy into each other and bounce apart?

Apparently they have some 720p footage of the rover descent. Cant wait for that footage.

Actually Nasa said they are dunes.

I feel lucky to be alive to see images like these come from another planet. It's just mind blowing.

Imagine what else is out there.

More of the same most probably.

Full size panorama from MSL. Not sure why they're missing some bits, or why they didn't cut it out properly (excess whitespace) - but I love the clarity!

censoring the Mysteron bases no doubt.

I'm pretty sure that's a photo that was constructed by stitching together all thumbnail images together

You will have to wait for the real photos a little bit longer

No, because the kinetic energy of the lab is reduced to 0 by impacting with an opposite energy by the other one. There WOULD be some elasticity in the collision, you wouldnt get a fused mass with 0 kinetic energy, but the majority of it would be expended. When two cars crash do they bounce apart and go backwards or do they come to a complete stop with a few small bits flying off. Go look on liveleak for some examples.

So the censorship is done by Spectrum then?

sad really

Are you kidding? Reading about this got me all excited and eager to watch any clips possible. I do not care for the Olympics. Sports are.. sports, still don't get how its entertaining

Possibly. But I think they used a samsung lcd and thats just a few dud pixels. Nothing to worry about.

The Chinese are talking about putting a satellite at a Langragian point to monitor space weather.

Though the Chinese are good at making up all sort of missions for the next 50 years which probably won't all eventuate..

I said "Most Australians" as in the average Australian, OCAU members tend to be a bit more educated and smarter than the average Australian to be honest!

For example I'm willing to bet my left nut that more Aussies watched Big Brother last night than watched Curiosity decent live!
