Commander Ken Cockrell, Pilot Paul Lockhart and Mission Specialists Philippe Perrin and Franklin Chang-Díaz, and the newest shuttle crewmembers - former Expedition Four Commander Yury Onufrienko and Flight Engineers Carl Walz and Dan Bursch, were awakened at 4:23 Central time this morning by "I Have a Dream," by ABBA, a song selected for Treschev.
Using the shuttle's robotic arm, Cockrell and Perrin will reach into Endeavour's payload bay and latch onto Leonardo at mid-morning. The pressurized cargo module will be attached to the nadir berthing port on Unity. After Walz and Whitson perform pressure checks, the hatch to the cargo carrier will be opened. Leonardo contains equipment, supplies and experiments necessary for the fifth resident crew's 4 ½-month stay in orbit.
The six Expedition crewmembers will continue their handover conferences and the 10 cosmonauts and astronauts will review procedures for the first spacewalk of the flight tomorrow. Perrin and Chang-Díaz will step out of the Quest Airlock Sunday to begin installing the Mobile Base System, a new platform which will enable the station's robotic arm, Canadarm2, to ride a railway the length of the station for future assembly tasks. Two more spacewalks are scheduled for Tuesday and Thursday to complete the Mobile Base system installation and to replace an ailing wrist roll joint on the station's robotic arm.
The Expedition Five crew officially assumed command of station operations last night just before 6 p.m. Central time, marking the end of the Expedition Four increment at 182 days. Onufrienko, Walz and Bursch are now considered part of Endeavour's crew, aiming for a homecoming on June 17.
Systems on Endeavour and the ISS are functioning normally as the two vehicles orbit the Earth every 90 minutes at an altitude of 240 statute miles.
