During the 6-hour, 53-minute spacewalk, Linnehan and astronaut Robert L. Behnken (out of frame), mission specialist, installed a spare-parts platform and tool-handling assembly for Dextre, also known as the Special Purpose Dextrous Manipulator (SPDM). Among other tasks, they also checked out and calibrated Dextre's end effector and attached critical spare parts to an external stowage platform. The new robotic system is scheduled to be activated on a power and data grapple fixture located on the Destiny laboratory on flight day nine.

This image was recorded with a digital still camera by a crewmate inside the shuttle's crew cabin. The NICMOS has been dormant since January 1999 when its original coolant ran out.

STS078-430-009 (20 June-7 July 1996) --- Astronaut Richard M. Linnehan, mission specialist, performs a test on his leg using the Torque Velocity Dynamometer (TVD). Dr. Thirsk was measuring changes in muscle forces of the leg in this particular view. The TVD hardware is also used to measure arm muscle forces and velocity at the bicep and tricep areas. Crewmembers for the mission performed all experiment protocols prior to flight to develop a baseline and will also perform post-flight tests to complete the analysis. Additionally, muscle biopsies were taken before the flight and will be conducted after the flight.

STS-90 Mission Specialist Richard Linnehan, D.V.M., sits in a chair during suitup activities in the Operations and Checkout Building. Linnehan and the rest of the STS-90 crew will shortly depart for Launch Pad 39B, where the Space Shuttle Columbia awaits a second liftoff attempt at 2:19 p.m. EDT. His second trip into space, Linnehan is participating in a life sciences research flight that will focus on the most complex and least understood part of the human body the nervous system. Neurolab will examine the effects of spaceflight on the brain, spinal cord, peripheral nerves and sensory organs in the human body

STS109-315-005 (8 March 2002) --- Barely visible within the Hubble Space Telescope's heavily shadowed shroud doors, astronauts John M. Grunsfeld (left) and Richard M. Linnehan participate in the final space walk of the STS-109 mission. The crew of the space shuttle Columbia completed the last of its five ambitious space walks early on March 8, 2002, with the successful installation of an experimental cooling system for Hubble’s Near-Infrared Camera and Multi-Object Spectrometer (NICMOS). The NICMOS has been dormant since January 1999 when its original coolant ran out. Astronauts Grunsfeld and Linnehan began their third spacewalk of the mission at 2:46 a.m. CST. Linnehan was given a ride on the shuttle’s robotic arm to the aft shroud doors by astronaut Nancy J. Currie, working from the aft flight deck of Columbia. After the shroud doors were open, Linnehan was moved back to Columbia’s payload bay to remove the NICMOS cryocooler from its carrier. Grunsfeld and Linnehan then installed the cryocooler inside the aft shroud and connected cables from its Electronics Support Module (ESM). That module was installed on March 7 during a spacewalk by astronauts James H. Newman and Michael J. Massimino.
