To begin Flight Day 5, the crew woke at 10:30 p.m. EDT to the song "We All Do What We Can Do" by Dan Keenan, a thermal protection system engineer, and Kenny McLaughlin, a launch pad engineer, for Mission Specialist Mike Fincke. The two shuttle workers created the song to honor those who have helped make the space program a success. In their note to Fincke they said, "Together as dedicated individuals we did what we could do to help."
Today Mission Specialists Drew Feustel and Greg Chamitoff perform the first of four spacewalks of this shuttle mission. The spacewalk is expected to begin at 3:16 a.m. and last six to six and a half hours.
Feustel and Chamitoff will retrieve two experiments and install a new package of experiments on ELC-2, which is already on the station. They will install jumpers between segments on the left-side truss, or backbone of the station, for ammonia refills; vent nitrogen from an ammonia servicer; and install an external wireless communication antenna on the Destiny laboratory that will provide wireless communication to the Express Logistics Carriers mounted on the station's truss.
