Hubble Servicing Missions

Launch – December 1990

• WFPC, GHRS, HSP, FOC, FOS

• FGS can also do science

Servicing Mission 1 – December 1993

• COSTAR, WFPC2

• solar arrays, gyros

Servicing Mission 2 – February 1997

• NICMOS, STIS

• fine guidance sensor, solid state recorder, reaction wheel assembly

Servicing Mission 3A – December 1999

• gyroscope failure in November

• computer, data recorder, fine guidance sensor, electronics improvement, thermal protection

Servicing Mission 3B – March 2002

• ACS

• solar arrays, NICMOS cooling system, reaction wheel assembly, power control unit

Servicing Mission 4 – May 2009

• WFC3, COS

• ACS repair, STIS repair, SIC&DH, gyros, batteries, fine guidance sensor, thermal blankets, de-orbit module
