EVA 4 - Massimino with EMS on RMS arm

STS109-323-035 (7 March 2002) --- Astronaut Michael J. Massimino, on the shuttle�s robotic arm, prepares to install the Electronic Support Module
(ESM) in the aft shroud of the Hubble Space Telescope (HST), with the assistance of astronaut James H. Newman (out of frame). The module will support a new experimental cooling system to be installed during the next day's fifth and final scheduled
spacewalk of the mission. That cooling system is designed to bring the telescope's Near-Infrared Camera and Multi-Object Spectrometer (NICMOS) back to life.
