For those interested, Curiosity is landing on Mars in about 2 hours. See NASA tv here
. It should land at 1:31 Eastern Daylight Time (5:31 UT), August 6th.
What makes this landing so interesting is that it will be done a la Rube Goldberg. See Seven Minutes of Terror
, which refers to the fact that it takes seven minutes for Curiosity to go from the top of the atmosphere to the ground, but signal from Mars will take 14 minutes to get to earth. So, when we get the signal that Curiosity has started its descent, it will have already been on the surface for 7 minutes...hopefully in one piece. Tension will be rather high till they hear (which I just learned could take a few hours to three days depending on how a number of factors come together).
