No date was reported for the mission, other than before the shuttle fleet is retired. From the article, 'A rehab mission would keep Hubble working until about 2013. It would add two new camera instruments, upgrade aging batteries and stabilizing equipment, add new guidance sensors and repair a light-separating spectrograph. Without a servicing mission, Hubble will likely deteriorate in 2009 or 2010.'"
