Bruce McCandless goes aloft from the Shuttle Pallet Satellite (SPAS) during an STS-41B EVA. Attached to the forward axis of the astronaut is the Trunnion Pin Attachment Device (TPAD), a device to be used to assist in recovery and/or repair of satellites in orbit by effectively allowing the orbiter to save fuel while an astronaut goes out to mount to a strong point on a stricken satellite; the astronaut then flies it to be grappled by the remote manipulator arm and stowed in the payload bay. -- source link
