Happy news. The Hubble Space Telescope is sending pictures again.
Imagine this: Your car fails and you're stranded. Instead of sending a tow truck, your mechanic electronically connects, runs some diagnostics, and enables some alternate circuitry. That fails, but they take additional readings and restart modules in a different sequence and with a bit of diddling (yeah, that's a valid technical term), your car comes to life.
That's what this was like.
