Title: Mars 2020/Perserverence landing tonight.
Post by: tonycollinet on February 18, 2021, 10:30:16 am
Am I the only one massively excited for this landing at shortly after 8:45 our time tonight.

Not only bringing the first powered flight to another planet, but set up for the multimedia generation with 23 cameras. Hoping for amazing imagery from this one, including mutual photos taken of each machine by the other. Audio being recorded also.

Landing in the bed of an ancient lake in a search for signs of life. Taking core samples for a future (launching 2026) return to earth mission with return about 10 years from now..

I have have full time Nasa Tv on today.

I hadn't realised it was happening until last night when we watched a Facebook thing from the South Downs National Park.

A talk from Chichester planetarium about the night sky and Mars.

I originally got muddled wrt time zones and was ready to watch from about 9 this evening through to midnight. Luckily saw on the BBC news site this morning that it's more like 7PM to 9PM that I want NASA live loaded. A mix up between PST and EST on my part I think.

Which actually works better for me as I possibly have to be up early Friday morning.

Looking forward to it.

And a helicopter. In space. Equipped with frikkin lasers.

That's pretty much on the awesomest end of awesome.

I've always made a point of never getting excited about any Mars landing until the thing is down and transmitting. This one's much the same, and the media continually bleating "seven minutes of hell" is downright tedious.

getting excited about the landing ahead of time seems like an entirely avoidable source of stress! Once it's down and producing results is the time to get excited. Investing lots of heartbeats and emotional energy in it before that is the preserve of those who are paid to make it work.

You are looking at a feed of data, and potentially it is already smashed to pieces  ;D

Depends whether you want to see all the trailers or wait for the main feature. 20:48 is what they were saying a few days ago

Likewise - since a small piece of my handiwork got smashed into a trillion pieces.

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.

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.

12 minute light speed delay. So when our 7 minutes of terror starts, it will already either be smashed to a million pieces spread over the surface of mars, OR safely landed calling home.

OR

Will it Schroedinger style exist simulteneously in both states untill we hear the tiny "Hello? Hello? I've Landed"

:D

I had this for about 6 out of 10 questions at the end of a staff forum earlier. I think it’s a way of making the eventual “I don’t know” sound better.

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, 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 bet Tom Hanks will be in the film adaptation, trying to put a round thing into a square hole

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.
