The STS-110 crew relaxes at the traditional crew meal before getting ready for launch later in the day. Seated, from left, are Mission Specialits Rex J. Walheim and Steven L. Smith; Pilot Stephen N. Frick; Commander Michael J. Bloomfield; and Mission Specialists Ellen Ochoa, Jerry L. Ross and Lee M.E. Morin. The cake on the table is also traditional, featuring the mission patch. STS-110 is the 13th assembly flight to the International Space Station, carrying the S0 Integrated Truss Structure and Mobile Transporter (MT). On the 11-day mission, the mission features four spacewalks to attach the S0 truss, which will become the backbone of the Space Station, to the U.S. Lab, "Destiny." The MT, a space "railcar," is attached to the truss segment and will make its debut run during the flight. Among the seven astronauts, Walheim and Frick are making their first Shuttle flight; Ross is making a record-breaking seventh flight. Launch is scheduled for 4:40 p.m. EDT April 8
