[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.

Now that is a space artifact. I've seen flight spares, and (successfully returned) shuttle payloads. Also a little UV telescope once flown on the X-15. But this...

That is so cool. And somehow, landing in a swamp and getting found by a legionnaire makes it even more cool.

Industrial archaeology of a sort and you know me and industrial archaeology! :o)

That is a very cool little piece of space history.

Ooh, awesome.

Also, how good is Grimes? And she's what - twelve?

I'm totally geeking out! Very, very cool! Doubly so that it has such an unusual history...

Neat SPACE object there! Maybe that helped show off the coolness of STEM to several of the women and girls in the crowd.

It looks well reserved given what it went through. (Not that I know anything about fluxgate magnetometers!)

I am unreasonably pleased that a flux magnetometer is a true thing, given the iconicity of the "flux capacitor" in SF (Back to the future movies; it was the MacGuffin enabling time travel).
