I’m a double EE dropout who became an electrician 25 years ago and I’ve never regretted it.

Electrician is really solid. The more automation there is, the more work there is for electricians to wire it. Plus data centers will only ever increase in numbers. It takes a lot of electricians to wire a modern massive data center.

That makes a lot of sense.

Okay Juno took photos of Io some of which were from several hundred to a thousand kilometers away.

I assume that IO has less gravity well than Earth. There are objects even smaller than Io that have had photos taken from orbits as well.

I always wonder why they can’t orbit closer and get even greater surface detail.

I’m basing an assumption that an object with less mass (like an asteroid or a moon) can be orbited much closer than a satellite around the Earth before the gravity well becomes an issue.

Are these missions at their absolute closest orbits possible given the fuel reserves?

100-50k above the surface but as close as possible enough to orbit

“The law that entropy always increases—the Second Law of Thermodynamics—holds, I think, the supreme position among the laws of Nature. If someone points out to you that your pet theory of the universe is in disagreement with Maxwell’s equations—then so much the worse for Maxwell’s equations. If it is found to be contradicted by observation—well these experimentalists do bungle things sometimes. But if your theory is found to be against the second law of thermodynamics I can give you no hope; there is nothing for it but to collapse in deepest humiliation.” — Sir Arthur Stanley Eddington
