Servicing Mission 4 (SM4), is the last Shuttle mission (STS-125) for the Hubble Space Telescope.[65] On SM4 astronauts over the course of five spacewalks will install two new instruments, (Wide Field Camera 3 and the Cosmic Origins Spectrograph), repair two instruments that have failed (the Advanced Camera for Surveys and the Space Telescope Imaging Spectrograph) and perform other component replacements that should keep the telescope functioning at least into 2014.
