Astronauts Drew Feustel and John Grunsfeld, of NASA’s Hubble servicing team, are currently completing their fifth and final spacewalk. If all goes well, at the end of this the space telescope will be in tip-top condition again.

A number of papers note that things have not been going smoothly so far. Yesterday astronauts Mike Massimino and Michael Good were nearly frustrated by a stripped bolt.

Massimino eventually resorted to brute force, or what NASA calls “steps developed quickly at the Goddard Spaceflight Center to carefully bend and break”.
