Sunshield deployed!

Not quite. The booms are out, but it hasn't been tensioned yet. The tensioning is one of the most complicated parts of the deployment. They are currently looking at the temperatures of some of the motors involved along with the power systems.

I was watching a docu on the Perseverance rover last night. I'm surprised there aren't more burnouts.

Seems to be working too. The average temperature difference between the hot and cold side is 368 F (205 C).

Deployment of the secondary mirror has started.

With that much heat radiation, they could have powered it with a steam engine.

Somebody let me know if it spots intelligent life anywhere in the universe.

I don't know if it could do that even if pointed at Earth.

Not usually hot enough to generate steam, but a Sterling engine might work.
