The astronauts are cleaning up the payload bay after the last servicing mission to Hubble.
So far, everything has eventually been successful, although some trouble getting in to STIS delayed the installation of the new thermal shield. The only disappointment has been the High Resolution Chanel on the Advanced Camera for Surveys, which NASA was not planning to repair, but had hoped would come back when the Wide Field Chanel was repaired. Alas, it did not, so ACS be stuck operating without it. However, as it was only used for about 25% of the observations with ACS, and ACS wasn’t working at all before this mission, it’s still a pretty big overall success.
