Congratulations to all concerned. TBH I wasn't 100% convinced it would work, but they managed to do it, so well done.

That number was prior to flyaway, so remaining fuel had to be used for that function.
I'm looking forward to the computed distance from 'Curiosity' that the stage would have landed, now given the burn time. Ditto range to heat shield and parachute, The hunt for orbital images of all these objects now begins. Depending on terrain, one or more may leave indications visible from the rover, or be targets for early translation over to, to examine fresh-dug dirt,
Yes, glad I am not the only one who is looking for those numbers! Let us know if you get them

If you were watching the video from mission control, you can surmise that no one in there was 100% convinced it would work either, based on how excited they were that it seems to have gone perfectly.

Does anyone have the miss distance that PAO stepped on?
Assuming that's what they were talking about, initial calculation was 2.27 km.
Target ellipse is 20km long. I don't know how wide.
Roughly 2 km. And the ellipse was almost due east-west, so they are either 2 km west or east of the target point. Either way, MSL is right in between the walls and central peak of Gale Crater.
That's in the neighborhood of the accuracy you need for a human mission to Mars.

1.4 kg of fuel left onboard
I heard it as 140.6 kg
It was 1.4Kg, can't be 140Kg- too much.
Jim
Yeah, I figured that number was too high. They must have mis-reported it.
I'm sure I heard 140.6kg. Remember the descent stage started out with 390kg propellant aboard so seems a good number to me, given a smooth descent without complications.
You did hear 140.6, as I did. That's right. Going from memory, 4 thrusters at 800 lbs each (3200 lbs) and hydrazine Isp at 230 gives about 14 lbs/sec (6.4 Kg/sec). So, they had about ten seconds of propellant left. Seems about right. Certainly NOT 1.4 kg.

Like a boss. That's five successful Mars EDLs in a row! With 4 different EDL techniques! JPL has this /down/. Time to give them the task of a manned Martian lander...

Got an idea for a cartoon (wish I could draw) A beefy, grinning, confident Curiosity taking the baton from a wheezing, exhausted, small Opportunity, its tongue hanging out. Curiosity says; "Thanks, brother - I'll take it from here!"

Not so fast. What's Curiosity's nuc power profile timeline for the out years, compared to Opportunity's solar power with dust cleaning?
