Cassini End of Mission events, Part 2 of ?

On Wednesday morning, [personal profile] emelbe and I saddled up and drove over to the Jet Propulsion Lab for a tour. We put her trusty sat nav on, and I noticed that instead of a car, the little icon was an x-wing. She turned the audio on. “Driven well you have,” said Yoda. “In a quarter of a mile, turn left. It is your destiny.”

It was decided that it was fitting for Yoda to be allowed to direct us to JPL.

There were banners for the Cassini Grand Finale up all over campus. This one is in the courtyard outside the science building, where I used to work, and go for a coffee in the mornings.

We filed into the Pickering Auditorium, next to the Flight Projects Center, to watch a short and slightly dated film about the Solar System, narrated by Harrison Ford. I have to admit that I was a little distracted whilst watching it, because the first scientist to appear in it, to talk about Mercury, was Claudia Alexander. She died of cancer, when in her fifties, a couple of years ago. I only met her a few times, but it was sufficient to discern that she was an absolutely delightful human being as well as a successful researcher. Despite my relatively small stature on the Cassini team, she always remembered my name. My eyes filled with tears when she appeared and they never quite cleared up.

Our next stop was the Mars Rover test facility.

I used to come here occasionally at lunch when I worked at JPL. Keep in mind this was back when they were testing Spirit and Oppy. (I’m getting old.) In those days pretty much the entire floor was covered in red rock and dust, but a couple of years ago, the engineers got fed up with constantly cleaning pulverised dust out of everything, and switched to the current setup. This has a contained pit filled with crushed garnet that apparently does an acceptable job of simulating most Martian terrain, and also features a nice swathe of clean linoleum so they can actually pull test vehicles out of it and do work on them without having to spend half a day dragging them somewhere else and cleaning them off.

I was happy to see that whatever the vehicle they’re currently testing, they still use Marvin the Martian as a calibration target.

We then traipsed up the hill to Mission Control. This building is tucked away behind the much more impressive edifice that is Building 180 (where the pomp and circumstance usually takes place at JPL). Mission Control had been redone in the eleven years since I last visited JPL, so I was chuffed that we were going to be allowed in.

“Space Flight Operations Facility has been designated a national historic landmark. This building possesses national significance in commemorating the history of the United States of America. 1985, National Park Service, United States Department of the Interior.”

We filed into the operations room, where we got to sit at the desks of the flight team on the condition that we touch nothing.

You’d better believe it was Selfie Central in there!

20170913_185232
Don’t you worry, I got mine too.

20170913_185444
Sun Microsystems, oh yes.

Call it in.

I don’t know how well it can be seen, but in the centre-left of this image is a set of three digital clocks with white digits on a black background. The top clock is UTC, the bottom clock is time since Juno JOI (Jupiter Orbiter Insertion) and the middle one is the Cassini Plunge countdown: 1 day, 18 hours, 18 minutes and 40 seconds when I took the photo.

You can also see where the Voyager ACE (mission controller) sits. People have been occupying that chair nearly continuously for forty years. Is that not a delightful thought?

20170913_190630
In the foyer, where there is a model of Cassini suspended from the ceiling, [personal profile] emelbe took what is now in my top five favourite photos of me of all time. I am pointing at the most important instrument on board Cassini and wearing my serious face.

Our final stop was the Spacecraft Assembly Facility or SAF building. I don’t think this has changed since I last visited it. It is pretty much just a gigantic clean room.

It is big.

20170913_191848
Very big. But, as it turns out, not actually big enough for the Cassini spacecraft, which had to be assembled in a different, even larger building.

20170913_192551
I spent a lot of time peering out the end window of the viewing gallery in the company of a small girl with a comfort-pillow. We were the only two to spot the person who climbed up the ladder to a small platform and then fished up their bucket after themselves. (The version of this video on Instagram is better but I can’t figure out (a) how to embed that here or (b) how to get the darn thing to back itself up to Flickr even though all my IG photos do automatically.)

We meandered slowly back toward reception - and the gift shop. We may not have quite cleaned the place out of Cassini swag, but we certainly gave it a go.

Yoda took us back to Caltech, and thence to the flat, where another afternoon spent horizontal was necessitated due to illness-related weakness. Nevertheless, the tour was definitely worth the expense of precious energy.

How extremely cool.

*jawdrop* I did not know about the Voyager ACE. That is a delightful thought. (Of course someone would have to be coordinating it, even still. Wow.)

I have the shot where Saturn's rings are backlit by the sun, and some of Saturn is illuminated by ringlight, as my desktop wallpaper right now in honor of Cassini.

Oof. That's a lot of sleepless nights.

I tune into DSN Now occasionally, but have no real idea of how often one might get data back - which leads me to consider a lot of sleepless nights when you may not even expect contact.

...nnnnnope.

I don't respond to every one, but I love these posts of yours about your work (and related topics). They'd make a great coffee-table book if you printed them all out and bound them all up together - a personal perspective on the space program or so some such, I dunno. Whatever; they're exceedingly cool, and thank you so much for sharing them!

Marvin the Martian! Voyager mission controller seat! These posts are amazing - thank you for sharing.

This is really cool. Thank you for sharing this; it's so neat to see how much goes into these missions.

Those are lovely photos, and I'm excited to see all the science all at work. (Goodness, forty years of Voyager data and still cooking...)

Also, Marvin is an excellent calibration target!

Also an excellent choice for calibration. And encouragement, hopefully.

Ohmai. Sun Microsystems. The plant outsourced to the UK was in my town. The town seriously panicked when it seemed Oracle wouldn't keep the plant open. Still makes me smile when I see java popups on my comp :P

Ooooyh. My friend has a wee boy. He's 10. He is space obsessed. It is wonderful. Thing is that he's So So clever with it that most of the time people are just like ....I...don't know...anything you just said?

But last time we met I got him to engage in a debate about Pluto. I basically said 'well my generation grew up with it as a planet so it was weird for us to be told it wasn't even if we understand X, Y, Z'. So we chatted. I was just about able to follow.


I met him yesterday and he was came at me with all these reasons as to why Pluto is not a planet and he had me lost about three sentences in but I just tried to engage and make him feel part of the gathering and important as best I could. The only reasons I knew that whatever he mentioned was smaller than a neutron was because it sounded like neutron with a language suffice that meant smaller. F. M. L.

But I try keep this kid engaged.

Well yesterday he also asked me what my fave planet was and was not impressed when I said is was Earth cause you know, we live here. Is ...is Ad-something and 5 million somethings away in cause you wondered. So I said my next was Saturn because A, its pretty epic and B, because I had a friend who worked on the Cassini mission and now I'm the dog's bollocks' tbh.


But then he kept asking me Saturn questions and I was just like Idk I just know she knows and she was there at the end yay?

I'm just so glad he's into it though.

Oh wow. That all looks rather special. And <3 Voyager. I remember Voyager fly-bys from my childhood - they were some of the things that excited me about Space! (Space.)
