The probe is shielded. And it's not so much about being powered up as the total voltage/current experienced by the circuit, which is probably larger if the device is on during the event where more is induced. For example, if a big enough coronal mass ejection hit Earth, the electric grid, basically being a giant unshielded antenna at that scale, would be fried no matter what was going on.

NASA's seven-year OSIRIS-REX mission ended on Sunday with the return of regolith from the carbon-rich asteroid Bennu. Researchers hope this pristine space dirt will reveal clues about the birth of our solar system and the genesis of life on Earth. https://nyti.ms/48vo5Gz

I bet we're going to yeet the biggest telescopes of all time into space in the next ~20 years. Like, multi-satellite telescopes with fairly large fields of view that are built to detect and track small, cold objects in our solar system.

If we get space construction going, then sure, but is robotic construction in space even in serious development atm? I would think there would need to be a decade, or at least many years, of in space testing to get the tech good enough to build something that has such small tolerances as those telescopes.

My bet is that we'll be creating some massive space telescopes that can fit on a Starship and yeet them up. No extra construction from multiple-launches required. The JWST's diameter is 6.5 meters, it looks like the Very Large Telescope is 8.2 meters. It probably won't be that hard to beat these. Like, as in a huge team of scientists working on that project as their pinnacle achievement can do it.

I went to Idaho to see the total eclipse in 2017. Well worth it. The totality was so far beyond the experience your brain is calibrated for it just cuts out for a while. I'm going to Indianapolis for a mini family reunion to see the one next year.
As some astronomer said, the difference between seeing a partial and total eclipse is like that between almost and totally losing your virginity.

Yeah, my wife's family is in Southern Illinois and we went for the 2017 one, and it's also getting the 2024 one. I'd say it should be a bucket list item for everyone, because it's fucking crazy. Gets instantly dark, the temperature falls rapidly, and it looks cool as hell.
From what I've heard, annular isn't really anything to get excited about.
