The gopro (whatever brand of "ruggedized commercial camera" they used) footage possibly being sent home tonight will be... nothing short of epic.

Tomorrow: "Um, well, it turns out that Tim forgot to take the lens cover off before we launched the rocket, so...."

They will deploy it tomorrow and do checkouts -- they'll do an initial flight within thirty days.

Um... Doesn't Mars have weather?

They're gonna leave some ultra light flying craft sitting on the ground for 30 days

 

Ok, yeah.  Kickass landing aside - that's definitely NASA. =/

They are not deploying the helicopter tomorrow - they need to spend several weeks making sure the rover is ready to move and observe, and drive to a suitable location.

Yeah I must have misunderstood something in the stream.

Weather is generally a problem because dust storms can cover solar panels, but the dynamic pressure from wind is basically negligible due to the low atmospheric density.

Okay - but when I watched 'The Martian'

they made weather on Mars look exciting.

Andy Weir (the author) admitted that this was the most deliberately inaccurate thing in the book. For thematic purposes he wanted the initial crisis to be caused by Mars, rather than human error, and the only one he could come up with was a storm. He knew that the Martian atmosphere is so thin that storms have very little force (even though they have very high wind speed), but for plot purposes he just ignored that.
