Okay, we're off and running! Please post all comments relating to MSL's transit to Mars here.


--------------------
A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

From what I thought was a very informative article in the January 2011 issue of Aerospace America from the AIAA:

"Things begin to happen fast at backshell and parachute separation, but the first thing the sky crane and Curiosity do is nothing." ohmy.gif "The contraption is programmed to free-fall for 1 sec to be well clear of the ... parachute canopy, risers, and backshell."

"Next (after MLE ignition) the vehicle maneuvers laterally to prevent having the backshell and parachute collide in midair or land on top of each other - the worst of luck 150 million miles from Earth."

This may have changed, although some kind of collision avoidance must still be included.
