One of the shaggy ponies and a horse, trotting in sync across their snowy paddock. Feeding time!

Spring has most definitely arrived now, so even though this was taken a mere 10 days ago, I think it can be considered a throwback Thursday entry. The transition from subzero temperatures, driving wind and snow to mild showery conditions has been very abrupt this year.

One of the fun things about visiting the parental abode is going through and labelling old photographs. Here I share a selection of those featuring me at various stages of my childhood.


Here I am sitting in the frame of what would become my aunt and uncle's house. I have no idea what image I was actually trying to achieve here, but I can't look at this without thinking of Heathers.

( It gets better. Or worse, I dunno. )

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 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.

[Image of a fluxgate magnetometer in its housing with its frayed MLI-coated cable curled round it. The destroyed connectors can be seen. The whole assembly is sitting on top of an antistatic envelope. The sensor housing reads: "CLUSTER-FGM SENSOR 08 FM1", where FM means "flight model".]

I gave an outreach talk at an open day this morning, to about a hundred A-level students, their parents and their teachers. The talk was focused on the Cassini end-of-mission science, but I managed to sneak in this bit of space history when explaining what a magnetometer does.

The fluxgate in the photo above actually went into space for a few brief seconds. It got about 5 km up before it was unceremoniously returned to the Earth. The Ariane 5 rocket that launched the spacecraft whose payload it was part of had exploded, showering the swamps of French Guiana with wreckage.

This sensor sat in that swamp for a good few weeks before a French Foreign Legionnaire fished it out.

I'm afraid that being blown up and mouldering in a tropical pond was, in fact, enough to kill it, but it's still a pretty cool object, and the students seemed to like seeing it very much.

This is me, my mum and my grandma at Hanalei Valley in Kauai, Hawai'i, USA. I believe we have stopped at a Point of View along the road into the valley. Items of special interest in this photo: my mum's glasses, my grandma's flowery dress and my yellow bonnet.

In the second installment of Weird Metal Contraptions I Was Placed In As A Baby, I give you my baby bouncer. At least this one features floral print fabrics instead of black leather like my high chair. The bouncer was modified by my grandfather (also pictured) so that he could bounce me with minimal effort. We’re on the lanai (porch) in my grandparents’ house in Honolulu, here.

For Throwback Thursday, here's a scanned photo of me flopped out on my maternal grandmother, who is bottle-feeding me. I think I'm only a few months old here. She was like a second mother to me when I was growing up, until she began to suffer from dementia when I was a teenager. I don't have a lot of photos of her, as she was not fond of having lenses pointed in her direction, so I treasure all the snaps I have of her.
