Hubble seems to be a little healthier today

NASA announced today that it thinks it has solved the glitches that caused last week's hardware repair to fail. One instrument failure was related to a bad software patch (kinda like when my Windows machine went down last month), and the problem booting the spare data computer has been called an "electrical event of unknown origin," so they tried again and it seems to be working. Maybe a squirrel got into Hubble's transformer; that seems to be the cause of most electrical events in my neighborhood.

Anyway, in a few more days, we'll know if Hubble's main cameras are back online or not. In the meantime, Hubble is still doing science, measuring the positions of some interesting stars to very high precision. It doesn't make for good pictures, but it's good fundamental astronomy.
