Rob Manning and I swopped emails last night - and we think it might make sense to pool all the questions people have about MSL (and specifically MSL's EDL ) into one thread - and then answer as many as make sense either via a Q'n'A in the style of the previous ones I've done with Steve and Jim - or via Rob's typing fingers.
It'll be a few weeks till we sort this out - but submit-away until then Doug |

Hey, Rob! Thanks for the update. (Surprising how the devil is always in the details for even the smallest things like the naming of names...<clink exp 40> lawyers. ) Appreciate the effort to answer this firestorm of questions, but please take your time; we all know you have much much more important things to do!
My big concern is touchdown/separation event sequencing. Based on dvandorn's previous questions, it seems like the fail-safe approach would be to receive weight-on-wheels inputs from at least three squat switch sensors for a fixed, albeit brief period--0.5 sec?-- (and at least one of said inputs from an opposing side of MSL) before cutting the bridles. This would ensure parallel ground placement and hopefully wash out spurious 'jerk' switch actuations from other events such as parachute deployment and 'sky_crane' engine max thrust during deceleration. -------------------- 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.
