I find it vaguely amusing to see the people in Mission Control (or whatever it is called) flicking through mahoosive ring binders full of dead trees.

Redundancy- having an analogue copy of the flight and mission plans is what they do, in case the hamster faints or the elastic band breaks.

Is Mission Control on this one in TX or are they being sensible and running it from for e.g. the JPL?

It's a good job mission control isn't in Houston, they'd be doing this by candlelight.

Outstanding though, I can't throw a ball and hit a nearby wall.

Well, seeing as how, within the next hour and a quarter, a device, manufactured on earth, that has my name microscopically laser engraved on it somewhere will either be sitting pretty in Jezero Crater, Mars OR  spread across the Martian landscape in a several of pieces, I for one am a little exited.
You've one-upped me there dude. I'm stoked for you :fistBump:

Not too rare as there are a few thousand names engraved but knowing one of them is mine is quite chuffalicious.

I'm blown away by this stuff.  As a child of the Apollo 11 era who became an engineer, anything like this has me hook line and sinker. Hell, my first boat was called Apollo XI !

Well, despite my world-weary cynicism earlier, I watched the whole thing and got hugely excited about it. Of course. It was brilliant, and I am really pleased for them. Loved the first picture on Twitter within a couple of minutes of landing!

We forgot about it until almost too late, and switched on just in time to catch the jubilation. Sorry I missed it.  I hope some novel data will come out of it now.

They're going to turn it into a book?

I watched a bit of a Nat Geo documentary about the design and build of Perseverance.

They had problems with the sample return tubes, which sit inside the drill bit when boring cores. Some of the tubes were getting jammed inside the drill bit.

It turned out that the cleaning regime to ensure samples were not contaminated in any way by earth originating factors were so effective that there were no hydrocarbon layers left to 'lubricate' the tube/ drill bit interface. They termed the state Unearthly Clean.

They had to adapt the cleaning regime so that the final solvent wash only cleaned the very end of the tube outer- the bit that might contaminate samples.

The devil is in the detail.

Very cool indeed. And I really can't wait till we landing things close enough to other things that they can film it from the "outside", as it were.

I was well impressed with the photo of the unit and parachute descending taken from another satellite. A good deal of calculation required to point the camera in the right direction I would think.
