Construction of the International Space Station continues today with the second of four scheduled spacewalks to install the S-Zero (S0) Truss segment. Shuttle astronauts Jerry Ross and Lee Morin will float out of the station’s Quest Airlock about 9:34 a.m.
The Atlantis crew – Commander Mike Bloomfield, Pilot Steve Frick, and mission specialists Ellen Ochoa, Rex Walheim, Steve Smith, Morin and Ross – was awakened at 3:44 a.m. by the song “Voodoo Chile,” by Jimi Hendrix. It was played for Morin, who will be making his first spacewalk, at the request of his wife. On board the station, the Expedition 4 crew, Commander Yury Onufrienko and flight engineers Carl Walz and Dan Bursch, also were awakened at 3:44 a.m.
During their 6½-hour spacewalk Ross, wearing a spacesuit with broken red stripes, and Morin, wearing a spacesuit with diagonal broken stripes, will complete the structural attachment of S0’s remaining two struts to the station’s Destiny laboratory. With all four of the struts attached to Destiny, S0 will be able to support its design loads, including the solar arrays that will be on the ends of the truss at assembly complete.
After attaching the struts, Ross and Morin will remove the large metal rods used to support S0 during launch and store them on the truss. The pair will also attach a second cable system to the Mobile Transporter, which will eventually enable the space station’s robotic arm, Canadarm2, to ride a railway along the truss structure.
For today’s spacewalk Morin will be working from a platform at the end of the Canadarm2, operated by Ochoa. Using the shuttle robotic arm cameras, Bloomfield and Frick will take photographs and video of the spacewalkers. Walheim will coordinate the spacewalk from inside.
Both crews are scheduled to begin their eight-hour sleep period at 7:44 p.m.
The next STS-110 mission status report will be issued Saturday afternoon, or earlier if events warrant.
