Euclid Updates
I’m travelling back to Barcelona today, later than planned because I’ve had a heavy cold that I struggled to shake off and didn’t want to infect fellow passengers on the flight. While I’m in transit I thought I’d share some updates about the European Space Agency’s Euclid mission.
The first thing to share is a piece by Knud Jahnke with news about Euclid’s issue with ice in the optical system. The latest intervention has led to an improvement, but since it is a closed system ice will probably form again – though perhaps not in the same place – and further procedures will probably be necessary in future. In the meantime, though, the survey resumes.
Now for some short videos -three, to be precise – about the Early Release Observations mentioned here. I posted another one in this series here. I think the titles are self-explanatory:
And if that isn’t enough, for those of you who like simulations here is another video about the Euclid Flagship simulation described in this paper.

I’ve read Knud’s two pieces, but why on earth (geddit?) can’t they include some dessicant compound, so that when a water molecule lands on it during its random walk then it stays there? I’ve not watched the Q&A video with Schimer but the list of questions at its start seems not to raise this possible way of dealing with it.

Don’t ask me, guv. I’m just a simple-minded theoretical astrophysicist.
