The Space Shuttle
Atlantis successfully launched Flight STS-112 from Kennedy Space
Center, pad 39B, at  19:45:51
UTC on October 7. The crew of six is on a mission carrying the
US$390 million S1 solar array truss to the International Space
Station (ISS). The crew consists of Jeff Ashby, commander, Pam
Melroy, pilot, and mission specialists Sandy Magnus, Fyodor
Yurchikhin, Dave Wolf and Piers Sellers. The shuttle is scheduled
to dock with ISS at 15:29 UTC on October 9.
The
Boeing-built S1 truss will be attached to the main S0 truss. The
electrical, mechanical and other connections between the S1 and S0
 trusses
will require 3 spacewalks. The shuttle flight scheduled for
November will carry the P1 solar array truss which will be
attached to the port side of the central S0 truss. The S1 and P1
truss segments each have three folding radiator arrays made up of
eight panels, which together can dissipate up to 72.000 kW of
heat. The S1 and P1 truss segments carry independent computers to
operate and monitor internal systems, ammonia tanks, pump
assemblies and nitrogen pressurization systems for the coolant
loops.
