I felt the urge to rewrite my introduction so I thought I’d use it as a starting point for a Subscription Meme, as I haven’t seen one going around for a while.

I’ve made a template, which I’ve filled out very wordily below. Please feel free to adapt it to your wishes, and please link this post wherever you like. (Please participate or share? I'm going to feel very sad if this entry sits here alone with 0 comments...)

[personal profile] emelbe and I set our alarms for 02:30 and 02:35 respectively, just to be sure we got up in time to walk over to Caltech for the end of mission. We dressed and poured coffee into ourselves, made sure we had our badges, and got out the door in plenty of time to arrive before 04:00, the official start of the event and NASA TV coverage.

Walking up to Beckman Auditorium (aka the wedding cake) from the south.

As it happened. )
Thursday was meant to be a quiet day, since we all knew we had to be up and at Caltech by 4 AM for the thing we’d all been preparing for: the actual end of mission.

In reality, there were some impromptu science meetings at Caltech, one of which I attended in the morning. I slipped out just before noon, because I had someone to meet.

I headed down from Beckman to South Mudd to see my former JPL postdoctoral supervisor, from back in those heady days when I was still a lab scientist, for lunch. I hadn’t seen him since 2006. I eventually remembered where his Caltech office was. I could’ve found the JPL one much more easily, but it would have required me to check in and get a badge, which seemed a lot of faff for lunch. Besides, there are nicer places to eat in Pasadena. Once in the correct corridor, I spotted his technician hovering outside the door, plus another UK person from the physical chemistry community whom I’d never met but knows the bloke pretty well. There were lots of smiles and hugs, and we decided to head down to a restaurant over on Lake Street.

We had a very pleasant hour of conversation, reminiscing and catching up. I had a shock on hearing that their children, whom I remembered as children or young teenagers, were now grown up and had careers of their own. Of course I knew that would have happened in the intervening decade-plus, but it’s not until you actually speak together about these things that they’re driven home to you. They were equally shocked on learning that Humuhumu has started school - and has a younger sibling! The bloke and I had been remiss in our communication, clearly. We talked of science, of course, and of politics and its effects on research direction, and of our worries about the future due to Brexit and the current US administration.

I am still kicking myself for forgetting to take a photo. You must instead picture me with a group of men: one starting to disappear into the frailty of old age, peering out earnestly from large-framed glasses, one solid and grey-haired and mostly silent with twinkling blue eyes, and one cheeky-grinned middle-aged bear of a chap with a shock of brown hair and a beard. All sitting together in a booth of a Japanese restaurant, eagerly shoveling the contents of bento boxes into our faces, occasionally bursting into roars of laughter while cheesy ‘90s music played in the background.

We parted with promises not to let another eleven years pass before we met again. I was left with the warm glow you get from (re)connecting with friendly, kind, intelligent people. It was a lovely way to buffer against the excitement and strain of what was to come on Friday morning.

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.

Tour, with side trips down memory lane )
I flew into Los Angeles on the Sunday before the last-while-Cassini-is-still-in-orbit-around-Saturn Project Science Group meeting began. I was feeling dodgy when I got up at 6 AM, but I napped in the taxi and took some ibuprofen, and hoped that the feeling would go away.

It did not.

I made sure my usual mobile pharmacy (ibuprofen, paracetamol, Rennie) was stocked in my rucksack before I boarded the plane, and was glad I'd done so about three hours into the flight when my fever started spiking. I alternated ibuprofen and paracetamol every two hours. The flight attendants kindly granted all of my requests for cold water/cans of ginger ale, which were frequent. It was one of the most miserable long-haul flights I've ever had.

I spent nearly all of Monday in bed apart from a brief foray out to get a hot Thai curry into my belly for lunch. This paid off on Tuesday, and I was able to spend half a day at Caltech to dial into the penultimate operations meeting. (There will be one more after the crash, but obviously we’ll no longer have an instrument status to report.) I was excited about this, because I had been saving up something for a very long time.

In fine fettle was the other option )

First, I received my Cassini Grand Finale stickers from the delightful [instagram.com profile] marka_design. I put one of them on my 15th and final Cassini lab notebook, and I plan to put the other on my laptop and take a photo of it when I'm at the end-of-mission events next week.

There was a JUICE meeting at my institute this week. It was not for our instrument team, but for another that we work closely with. They convinced the project scientist to attend. He gave us an informative and exciting presentation, but most importantly, he brought a small stack of the very first official ESA mission stickers. I actually didn't snaffle one because I went off with my counterpart on the other team for an hour and a half splinter meeting. However, the PI from their team kindly saved us each a sticker.

The first official JUICE mission sticker, showing Jupiter, the Galilean moons and the JUICE spacecraft. This will go straight onto my new laptop when I receive it. It seems oddly fitting to be retiring one laptop and beginning to use another right at the end of the Cassini mission.

This is Sad Batman. Sad Batman, a black crayon rendition on orange construction paper who looks a lot like a Christmas tree with a bat head, is sad, "because he lost Wildstyle and Emmett". This is a reference that will make no sense if you haven't seen The Lego Movie and hence will not make you LOL as hard as I did.

On a completely different note, check out who's fashion-ready for the Cassini End of Mission. We were at Marks & Spencer buying school clothes last weekend when Humuhumu spotted this white fluffy jumper with pink sequin ringed planet. I couldn't resist.

(I meant to post this yesterday but ran out of oomph. Er, maybe it's still Thursday somewhere?)

I realise this is not the most exciting photo in the world, but my Fun Space History Fact of the Day for Throwback Thursday is that the Cassini spacecraft distributed operations computers OS of choice is...Solaris. Note the countdown clock in the upper right corner of the screen. Only two weeks left.

Side note: I love those weird eye-bendy default backgrounds in Solaris. They remind me that my first experience learning to use *nix properly was on the Sun Sparc 5 workstations in the Von Karman library basement at the University of Southern California.

Yesterday, we celebrated the retirement of one of my lab colleagues (second from right). He spent 52 years working as a technician in our lab. Power supplies he built for dozens of space missions are scattered throughout the solar system. He is a (largely) unsung hero of space history, Hauksbee Award notwithstanding. Trevor Beek, I salute you. I hope you enjoy many years in contemplation of a job well done.
Hello, I'm not so good at posting this week, due to it having been a bank holiday weekend which was also possibly the last gasp of summer, the bloke returning home from Nairobi and us turning around immediately afterward to go camping in Devon, and then back to drowning in work. We actually have some hardware in our hot little hands for the Engineering Model of our instrument for the JUICE spacecraft, and orders being placed for more, and that feels good.

I want to write up the camping weekend properly but for now, a preview from the dairy farm's ice cream stand.

From left to right: S, Humuhumu, Keiki and S's younger brother J*, sitting on a simple wooden bench eating ice cream in cones. Backdrop is the beautiful Devonshire countryside.

* J, believe it or not, is only a few months older than Keiki. He is enormous.
It is now just over three weeks until Cassini plunges into Saturn’s atmosphere and the mission (but not the Project) comes to an end. I grow a little sentimental.

This is the flight spare of Cassini’s fluxgate magnetometer sensor, which will live on. We use it for command simulations on the ground.

This is a 1:25 scale model of the Cassini spacecraft, with the Huygens probe attached to its side. It includes the magnetometer boom, which is hidden in this view. These were distributed to the payload teams. It's been in our group longer than I have (>11 years).

I recently ordered a big perspex display box for the model, so we can have it on show at the upcoming Imperial Fringe festival, post-mission-end. I’ll be giving a talk at the Farewell to Cassini exhibit. Details to follow (on the Londoners filter) when they’re confirmed and the web site for event registration is live.

This is a screenshot of NASA Eyes on the DSN that I took on 4 August. DSS-14 at Goldstone (the antenna in white on the left) is receiving data from Voyager 1 (spacecraft shown on the right). I accompanied this with “We’re still listening” on [instagram.com profile] magnetometrist on Instagram.

NASA has a poll, open until Tuesday 29 August, to choose a 60-character-or-less #MessagetoVoyager, to be sent on 5 September. If you want to vote on a message, go here.
On the previously mentioned trip to Amsterdam, the bloke and I stayed on a canal barge in the Westerdok.

This was the much bigger cousin of the holiday barges that pootle up and down our Worcestershire canal. The main bulk of the hull served as the home of the bloke who ran the B&B. We were in the wheelhouse, overlooking the canal. The docks seem to serve as pretty much permanent moorings for the barges in this area. Each one had a small garden, and there was even a floating children’s play area.

It was surprisingly quiet given that the location is a mere 15 minute walk from Centraal Station. We could hear a distant roar of traffic, but mostly we heard the hangry cheeping of two adolescent coots and the occasional quack of a duck. We also found a great crested grebe nesting a few boats down. It was definitely brooding, as we never saw the nest unoccupied.

Urban great crested grebe nest
The nest itself was a rather wonderful construction, being a mix of urban rubbish and plant detritus, with a few hollyhocks artfully arranged around the edges. The grebe had two female mallard bodyguards, who immediately came to circle the nest at a careful distance, giving me the side-eye when I hopped down on to the dock from the pavement to take photos.

The barge proprietor tiptoed in every morning to leave us breakfast on the table next to the wheelhouse. It included a bottle of freshly squeezed orange juice, muesli, yoghurt, and hardboiled eggs nested in knitted cosies. Much as I wanted to sleep in, the prospect of getting that into my belly when I heard his footsteps got me out of bed pretty early both mornings. We received so much food at breakfast that we were able to make sandwiches from the bread and cheese to squirrel away for later. We ate these in the Vondelpark on the first day, and for supper on the second after the lunch at Rijks.

Apart from the sheer pleasure of walking around Amsterdam, we also indulged in a trip to a Michelin-starred restaurant for a very belated birthday treat for me. We spent three and a half hours eating lunch at Rijks, which is next to the Rijksmuseum. The bloke had mentioned that it was my birthday when he made the booking. As a result, in addition to our pudding, I got a white chocolate candle with sorbet and a little message inside. We sampled both white and red wines, all by Dutch winemakers “from everywhere in the world” (e.g. New Zealand and South Africa).
