Dominion can handle it with the help of the Chinese...
BSOD on the Red Planet?
Purple Rain.
They had a watchdog timeout that rebooted the drone; it happened when they tried to spin the rotors up to 2400 rpm (which I have to admit is pretty fast for blades that big).
It struck me as pretty remarkable that something as fundamental as a watchdog timeout would have happened “at the job site,” so to speak, but you can’t catch every detail. Especially when the environment is as radically different as the surface of Mars.
I hope they can fix it with the new software. Bit of a long data link, but that’s why error-correcting codes were invented. NASA controlled the New Horizons spacecraft at a much longer distance.
Lot of good verbiage, but shouldn’t his have been anticipated back on earth a long time ago?
I bet the IT guy does not show up today.
They had a contest to name this little flyer. I thought it should have been called ‘Mayfly’ because it won’t fly for very long. It MAY not even FLY at all!
1202 error?
There is no better instructor than reality...............
I bet he has an Indian accent....................
I’ve been watching the fascinating videos about the Apollo Guidance Computer and how “restart on failure” has been one of the cardinal rules for space software ever since. Because you just can’t test and guard against everything...
Thanks to the brilliance of Margaret Hamilton.
And his name is Hank.
They probably didn’t test the power-up sequence at -60°C and in a near vacuum atmosphere.......................
Margaret Hamilton?........................... Oh, not THAT Margaret Hamilton!.....................

From the article:
“...move the new software through the rover
to the base station and then to the helicopter...”
-
I know what the rover is,
and I know what the helicopter is,
but what is “the base station”?
I think they did, in a big vacuum chamber. But they couldn't simulate the exact solar conditions they'd have on the Martian surface, and the temperature soak conditions, as you alluded.
They probably left it with some items "to be determined," knowing they could reprogram it in situ. I'm sure they had a list of parameters that they could settle before launch, and another list of parameters that might have to wait till they could do site testing.
A real nail-biter, I'm sure. If they can fly and recover it without tipping it over, it will be very impressive.
I think the Gil Scot Heron song Whitey On The Moon pretty much guaranteed that U.S. Government-sponsored planetary exploration will be done by robots.
Margaret Hamilton reminds me of someone I once liked very much.
