A spider in the foreground appears to be dancing on the lightning mast near space shuttle Discovery as the shuttle roars toward space on mission STS-120 to the International Space Station. Liftoff of Discovery was on time at 11:38:19 a.m. EDT. The mission is the 23rd assembly flight to the space station and the 34th flight for Discovery. The STS-120 payload is the Italian-built U.S. Node 2, called Harmony. During the 14-day mission, the crew will install Harmony and move the P6 solar arrays to their permanent position and deploy them. Discovery is expected to complete its mission and return home at 4:50 a.m. EST on Nov. 6. Photo credit: NASA/Sandra Joseph, Tony Gray, Robert Murray
