JWST

You must pretty proud, Chuck! It's wonderful that the wealthiest nation on earth (I think!) spends the money on something as incredible as this rather than just bombs. This stuff is important. Real "makes you feel small" stuff. Mind blown!

If you can make an extra cold air-conditioning work way up in space then my overdrive pedals must be a walk in the park.

NASA had help from CSA & ESA. Its a fair bet that NASA paid for the lion's share.

I'll bet that was one happy lion.

JWST's MIRI is experiencing some unexpected friction with the filter wheel.

NASA has convened an Anomaly Review Board to determine the cause & corrective action. Here's a video of the qual model Filter Wheel in action.

Well, they should have taken my advice on using Penrite instead of using Amazon Basics!
Don't they watch Project Farm!!!

Selecting a lubricant that will work for 20 years, in a vacuum, not contaminate optics, and remain slippery at cryogenic temperatures is no easy task.

I went on Penrite's website and tried to select an oil for JWST. Under vehicle type, "Space Telescope" was notably absent.
