Picture of a metal box with frames for PCBs (printed circuit boards).

I realise this may not be the most thrilling photo ever, but I'm not ashamed to say that I almost cried when I saw this metal box. This box represents 18 months' worth of work on my part (and others', but a lot of it was on me to coordinate) to get A Certain Space Agency to approve our soldering qualification plan for our flight electronics for the JUICE mission. The existence of this box means that we have been allowed to manufacture actual physical hardware rather than just endlessly iterating on bits of paperwork describing the hardware. It's not just spreadsheets and Word documents any more! There is a METAL BOX, and we will Put Things Into It, and heat them up and freeze them repeatedly, and shake the box around violently to ensure that bits don't fall off of it.

I may shed tears when the PCBs arrive and we can put them into the frames.

METAL BOOOOOX \m/

This is a photograph of two children's Stage 2-3 car seats. This may not look exciting to you, but believe me, I was thrilled, because Keiki is no longer in one of those five-point harness jobs (Stage 0/1). It has never been a joy getting him into that seat, especially once he was big enough to figure out that he could make it really difficult to get the harness fastened just by leaning forward/leaning backward/sitting on his foot/trying to lick your face/insert any annoying activity, he's guaranteed to have tried it.

I will clean up and donate his old seat. I was, however, sorely tempted to stage an "Office Space printer" execution [link goes to YouTube video, 01:38] for it. It should be grateful I don't own a baseball bat.

When this photo was taken, we were on Package #10 of 12 of the Lego Saturn V. As usual, I am Assembly Engineer and the bloke is Integration Engineer. We are drinking tea out of what are possibly the world's nerdiest mugs: The Grand Challenge Equations (courtesy of the San Diego Supercomputing Centre some 15 years ago) and the Cassini Grand Finale commemorative cup. Telstar is helping us.

We now have only Package 12 left, with the lunar module and nose cone.

Leiden Centraal to Noordwijk
A selfie I took on the bus from Leiden Centraal to Noordwijk. The bus takes about 45 minutes, so most people opt for a taxi when they’re visiting ESTEC. I like the bus, though. It’s a really pretty route through the city and out into the countryside. Plus, it only costs 4 euros.

While I’m on the subject of space agencies, here are a few links.

  • Want to holiday like an Elder God? Try these lethal exoplanet destinations! Galaxy of Horrors (h/t to [personal profile] redsixwing)

  • For a more soothing experience, you can watch a mildly animated page of the Deep Space Network stations uplinking and downlinking data from different spacecraft. I sometimes do this. I mean, I have a PDF with all the scheduled DSN passes for Cassini, but let’s face it, this is much prettier. Eyes on the DSN.

  • And finally, in Geeky Space Swag news, the Rosetta mission shop has been updated with new shirts and hoodies that include the cartoon spacecraft from the “Once Upon a Time” video series about the mission. Best of all, you can get your mitts on a cuddly/plushy toy of Rosetta and Philae, or donate one to be sent to a primary school.

Autumnal or vernal, depending on your hemispherical orientation.

Also, it is my birthday and this morning I opened my gifts with two eager assistants. We were all very pleased by the cuddly Jupiter which arrived without sender designation. Mystery sender has since been identified as Dear Friend Josh. \o/


Me, Humuhumu and cuddly Jupiter. Two of the three of us sporting some outstanding bedhead. Photo processed with the "Saturn" filter in Google Photos.
I'm spoiler-immune AND I read the book before I went to see the film, so I will do everyone who is spoiler-sensitive a favour and simply put this entire post behind a cut.

Spoilers, spoilers everywhere I'm sure )

Still, A++++, will def get on DVD and watch again.

Humuhumu in an astronaut outfit, with Telstar.

Meant to post this on Caturday, but there was no time, what with the parkrun and going to look at bicycles and gardening and general parenting of one very active toddler and one baby who's just learnt to crawl and has markedly more suicidal tendencies than his sister, including a blatant disregard for the spikeyness capabilities of the cat.

There was a dress-up day for charity at Humuhumu's nursery last week. Every girl in the toddler room was a princess.
The bloke brought home an infrared camera from the forest he's doing experiments in at the moment. Naturally we set it up in the back garden overnight.

And we learnt we have hedgehogs!

Less surprising was the discovery that we have a Telstar.

This evening he said he had to nip to Homebase to get some supplies for tomorrow's forest experiment. This is what he came home with.
  • hose clamps
  • gaffer tape
  • cable ties
  • heavy-duty plastic sheeting


Currently trying to decide whether or not I should be worried.

Keiki and I spent two part-days visiting Smithsonians in Washington DC whilst we were staying in Silver Spring, MD, for [livejournal.com profile] dizzykj’s wedding. I’ve wanted to go to a Smithsonian (any of them!) since I read about them as a child, and I was as thrilled to be able to go this May as I would have been thirty years ago.

On our first expedition, we rode the Red Line from Silver Spring to Judiciary Square, and walked from there to the Air and Space Museum. Judiciary Square was eerily deserted. I got the feeling it was a bit like being in the City (in London) at the weekend: places that are absolutely heaving Monday through Friday are completely empty on Saturday and Sunday.

+15, Air & Space Museum )

After all the tech, I wanted to spend a little time appreciating nature so we headed for the nearby Botanic Gardens. I was hoping to get a cup of tea there, but it turns out to be pretty much the only place on the Mall that doesn’t have a cafe. I had a quick spin through the glass houses and then went back to the Smithsonians.

+5, Botanic Gardens )

I chose to have my late lunch and very delayed cup of tea in the National Museum of the American Indian. I later discovered that I’d chosen one of the best of the overpriced Smithsonian cafes to eat in, according to the locals in the wedding party. I did think my enchiladas were pretty good at the time, but it was still nice to have my unintentional good judgment validated!


The very beautiful internal architecture of the mostly harrowing National Museum of the American Indian. I didn’t take any other photos inside, just experienced all the exhibits, which apart from the modern ones designed by Native Americans, were pretty unremittingly depressing. It’s kind of hard for them not to be when the treatment of native peoples by the US government was (is…) appalling for most of the US’s history.

Keiki sat with me and quietly watched a fifteen minute film about the tragic nineteenth century removals of native peoples from their land, so when he took a shine to a rattle in a Navajo design in the shop afterward, I got it for him. It’s now one of his favourite toys.

I was marking lab notebooks this evening when this bit of paper fell out of one of them.

Click to embiggen to readable size


A tiny, pedantic part of me was annoyed because it's Allen key, not alan key. A larger part of me was giggling over his love for his ruler. But the biggest portion of me was bemused because his lab partner fell only slightly to the right of his lukewarm feeling for a bit of curly wurly. I'm sorry, what? His lab partner is a rather attractive redhead, where "rather attractive" is just this side of "Pond in a short skirt". (I hasten to add that the young lady in question was always appropriately attired for laboratory activities, e.g. not in a sexy policewoman outfit. I also hasten to add that the students' appearances have no bearing upon my marking. I am fair and objective in intellectual matters.) She was quite a good experimentalist, too. I'm dying to ask him about this carefully constructed graph, but unfortunately I'm afraid we will have rather a lot of other things to talk about in his interview, such as a certain absence of observational data having to do with the actual experiment.

Then again, I may have just hit upon the explanation for that.

I leave you with a couple of jokes from the Kohn Award lecture delivered by Lord Martin Rees, Master of Trinity College at Cambridge University and Astronomer Royal, at Imperial last night.

Joke 1: A member of the audience asked Lord Rees how long it might be before humans can develop beings that are more intelligent than we are. The postdoc sitting next to me leaned over and muttered wryly, "About nine months."

Joke 2: Lord Rees displayed a diagram of an Ouroboros with the size scale of the universe from micro- to macroscopic arranged around its body. He then said there was another scale on which "99% of scientists and all biologists" work, which is that of complexity.

(Joke 2 might only be funny if you're not a biologist. In fact, it might only be funny if you're a scientist. On further consideration, it's probably only funny if you're a cosmologist with a superiority complex.)
