The briefing began with the introduction of Tomas Gonzalez-Torres (Lead Extra Vehicular Activity Officer). The spacewalk team included Pierce Sellers (EV-1), Mike Fossum (EV-2) and Mark Kelly (coordinator and pilot). Three new EMU's (space suits) were provided with hardware upgrades (warning systems). The 1st EVA would take place on flight day 5 and would include the exchange of the 3 EMU's. The 1st task was the installation of the blade locker, a device used to prevent severing of cables. The team will also install the Interface Umbilical System (IUS) which is an extension cord for the mobile transporter. EVA-2 task will be to replace the old Trailing Umbilical System (TUS) with a new one.
