While we were all leading our mundane lives the past week, astronauts John Grunsfeld and Andrew Feustel spent 7 hours installing a new camera on the Hubble Telescope. This cam replaces one that was built in the 90s and is sensitive to infrared and ultraviolet light as well as the human eye’s wavelengths. As we have previously mentioned, this is NASA’s final trek that over an eleven day period includes replacing a key computer.
