Did anyone catch the Daily Show (January 18th) segment on Stardust?
Priceless!

On Mars there is less gravity, which should mean that there is less impact forces because the equipment doesn't weigh as much. It also bounces around a few times after it touches down.Aquila Hawk wrote:Another thing that comes to mind in respect to the landing, why was the helicopter idea used instead of someother landing technique? The first thing that comes to mind for me is the airbag system used on the MERs and Pathfinder. Combined with parachutes that remained deployed until touch down, there should have been sufficient protection for the return vehicle. However, since the probe's chute did not deploy, this really is all speculative, but it seems like a less risky recovery. I have to also say that the probe failing to deploy it's chute, falling over a hundred kilometers through an atmosphere known for reducing metors to the size of peables, crash landing, and still have viable scientific material says a lot about the durability of the spacecraft and it's design.
Well, the reason that wouldn't work is because we're not on Mars. We have almost two and a half times the gravity, we have to worry about changes in pressure from even a small change in altitude, etc.Aquila Hawk wrote: Another thing that comes to mind in respect to the landing, why was the helicopter idea used instead of someother landing technique?

I LOVE the Daily Show, and I watch EVERY episode, but that was I while ago, and I can't remember it.albutterworth wrote:and back to Stardust
