This will be the last Hubble servicing mission. After this, Hubble will be as good as it's ever going to get! Hubble has been an incredible success, supplying amazing, remarkable images since the first Servicing Mission corrected the original errors in the optics. Subsequent servicing missions - sometimes wrongly called "repair" missions - have both replaced critical components and provided important upgrades that have greatly extended the capabilities of the Hubble Space Telescope. It would be great if everyone could tune out the reality shows and other assorted offal that fill our idiot boxes and briefly watch some amazing work get done this week in one of the most challenging workplaces ever - outer space!
