Gregory C. Johnson – Pilot
This is Johnson’s first trip into space. It will be his role to manoeuvre the Shuttle into position to capture Hubble.

Michael Massimino - Mission Specialist
Massimino will make his second trip into space and to Hubble. Massimino spent over 14 hours conducting two spacewalks on SM3B, his first space flight.
