Servicing Mission 1 (SM1)

Also known as shuttle mission STS-61, Servicing Mission 1 was launched to correct the Hubble Space Telescope’s primary mirror flaw, perform maintenance, and add/replace some of the telescope’s scientific instruments.

Major highlights of the mission include the replacement of the Wide Field Planetary Camera (WF/PC) with Wide Field Planetary Camera II (WF/PC II), the replacement of the High Speed Photometer (HSP) with the Corrective Optics Space Telescope Axial Replacement (COSTAR), and the installation of new solar arrays.
