It is interesting to know exactly at what instance the landing sequence is activated and will it be activated from the control center on earth? the 14 minute delay in the signal transmission makes the whole maneuver very interesting.

Looking at what you've mentioned about landing the rover using a rocket propelled "remote controlled" sky crane, a question that occur to me: Is it the manual control from Earth to control the sky crane? If yes, then how much delay in the response of that "sky crane" will be after the commands are sent? This looks not possible to me.

Here's video of a related space development: SpaceX conducting a full duration test firing of its Merlin 1D engine: http://www.youtube.com/watch?v=976LHTpnZkY&feature=youtu.be

The complexity of this undertaking is mind boggling. Lowering the rover down on a tether from a rocket propelled remote controlled vehicle? Indeed, no evidence of the K.I.S.S. principle here. That 14 minute delay to find out if all went according to plan is going to be brutal at mission control. Great video, BTW.

We'll find out if that's true in about six weeks.

Personally, I would want samples from the crater. Data of Mars would be advanced quickly, from the back splash of magma displacement. Look for unique elements from the planet and the striking body to correlate with future samples. And that's before you leave the crater.

I was at Aerojet in Sacramento during the moon landings. Aerojet produced the engine (that fired behind the moon) to bring the men back from moon orbit. The live feed was put on the Aerojet phone system, and we all sat there holding our breaths. There was a voice-over countdown that reached zero a couple of seconds before we heard the signal from the capsule. Perhaps those were the 2-second telemetry delay (while we sat there without oxygen to our brains for 2 seconds). The engine never failed, but perhaps some of our hearts did.

Mars missions have curses. The mission team here multiplied the curse 100x by failing to adhere to one fundamental principle: K.I.S.S.

They have had orbiters photographing the Martian surface for a decade now, and they can spot things smaller than existing rovers. They chose the landing site partly to be boringly flat.

"...then gently deposit it on it's wheels on the surface." (ie. deploy at 20m then descend to 7m) Looks easy in the animation... (haha) Liked the way he added "...on its wheels..." Wonder how they are going to determine when it is on the ground and not high centered on a big boulder...
