As part of final preparations before transfer to the launch pad, Atlantis will be lifted vertically into its VAB high bay and mated to the twin solid rocket boosters and external tank. The STS-110 mission resumes International Space Station assembly operations with the delivery of the S0 truss, which will support solar panels providing additional power to the Station. The payload will also include the first part of a Mobile Transporter that will provide a moveable base for the Station’s Canadian robotic arm. STS-110 is scheduled for launch April 4
