Next Stop Mars

Kubrik's classic from '68 - hard to believe - and perhaps at the peak of our technology optimism with films like Logan's Run and Star Wars to come.

I am following NASA's $2.5B Mars landing "Curiosity" on twitter.  This is real sci-fi stuff : to drop the one-ton probe on Mars (distance 352 millions miles from Earth), Curiosity separates from its spacecraft and enters Mars' atmosphere at 13,200mph; it has 78 miles to decelerate for a soft landing . . .peak temperatures reach 3,800F.  Thrusters ignite to halt spin and engage heat shields while friction slows the vehicle by 90%; further thrusters keep the capsule on track.  A parachute deploys to slow the descent further.  Four minutes into landing procedures the heat shield separates and radar looks for a landing surface (5 miles out, 280mph).  The back-shell, with parachute attached, jettisons and eight rockets fire for the final manoeuvre (1 mile, 180mph).

Within 100 feet a skycrane spools out nylon cords to lower Curiosity onto Mars. Once touchdown, the cords sever and the skycrane flies away to crash nearby.

It kind of makes me wonder why I have such a hard time clearing the garage or, for that matter, doing anything.
