ESA's Space Telescope Euclid has recently been having a problem with ice building up on one of its mirrors. How did it get there, and how are we removing it?

Stuff that goes side ways in and out of space craft then brain power overcoming problems with limited tools at distance is a wow .
Thanks for making this video! It's so fascinating that we have sent out super-expensive observatories into distant orbit where we'll never be able to repair them ourselves. I'm so impressed by the work done by our space agencies.
All while on a politically motivated budget with barely any guarantees. Funding gets axed, programs slow, then suddenly there's an influx of cash but most of it has to be used on premier projects with specific vendors and contractors in mind, and then all the wonderful projects that get by on life support finally get done but cost three times as much as just quickly and fully funding these smaller projects from the start. People make fun of SLS, but NASA was legislated into a corner by Congress to repurpose shuttle technology to supposedly save money, but the actual point was to keep the same shuttle era companies and contractors in business. Jobs. Then they're working on lots of infrastructure that needs to work with old and new technology. That's just a little bit of the bureaucratic and political madness that somehow sends us to the moon and let's us map spacetime and fly on Mars.
Clear and fun to learn! Thanx!
Great news! Well told!
Damn, thanks for the excellent explanation.
Water is described as a universal solvent, effectively it can ‘get into’ anything. Your video, Chris, was a fascinating account of why and how ice may be formed on some mirrors of telescopes in space, and how through sublimation it is possible to rectify the problem. A fascinating account. Many thanks
The various failure modes that are anticipated by the designers and provided solutions for is fascinating to me. When Hubble had her teething problems, we sent astronauts up in a shuttle, captured the telescope, swapped out the offending parts and let her fly again. Obviously that was never an option with the Voyagers, nor the Parker Solar mission, nor with those machines we park at L2, so mission planning is far more dicey. And yet they are so well designed that we nearly always exceed the mission durations by incredible amounts, and in the end we gain so much additional knowledge about our cosmic neighborhood.

Thanks Chris, keep it up! ❤
How about placing super-chilled plates near the mirrors (on future space telescopes) to draw the moisture onto them?
Excellent explanation!! Could a specialty valve be installed in future telescopes to vent the heated vapor back to space?
Where will these water molecules go? Staykng inside ... condensing else where disturbing functionality? Or condensing at a planned surcace staying there ... or beeing "transferred" to space?
Very interesting again! If the lense on my camera on my star tracker in my back garden complains about fog, I just get my wife's hairdryer to heat it up and I am fine 🤩!
I will think about this next time I'm tempted to complain dramatically about having to scrape my car windshield in the morning.
I thought water boils and then dissipates in every direction in a vacuum.
Yeah. I wonder about it. I don't think that the telescope is pressurised. So, the (gaseous) water molecules should eventually find their way out, right?
What about starship? I’m sure that Elon for a small price would have starship visit the satellite in just a couple months! Starship can do anything! Starship is gonna be ready immediately! All you need to do is to put FSD (full self driving) on your starship and it will go anywhere you say in the universe! Starship! Starship! Starship!
What in the actual fudge-round is a "smart-way" and a "windscreen"? Oh you mean circuit and windSHIELD? Got ya "mate" A telly mean for viewin' tha Currant Bun has a lot of Bottle & Stoppa in it yeah? 😂
Spot on chris 🚀🛰🛰🌙🌞🌞🌞
