Pre-launch dress rehearsal on the launch pad.
Liftoff for shuttle Endeavor on mission STS 134 is scheduled for about 1:47 p.m. MDT on April 29th. The cargo bay closeout has been completed, with the Alpha Spectrometer safely tucked away and ready for it's transfer to the ISS. The crew has been continuing with simulations and rehearsals for the big event.
The mission to ISS is planned to last 14 days, with the possibility of a two-day extension. The shuttle is expected to land at the Kennedy Space Center. However, I would wonder if they should rethink that and land it at Edwards AF base which is much closer to its new home in California. After all, flying the shuttle from Florida generally costs about $2 million per flight!
With the closeout of the STS program this year, NASA has determined that the shuttles and the shuttle training equipment will go to museums around the country. Shuttle Endeavor has been selected to go to the California Science Center in Los Angeles.
