Hubble Telescope Rescue

Two spacecrafts, the Atlantis and the Endeavor, are parked at Cape Canaveral ready to be launched.  The Atlantis is ready to be launched to start its mission to repair the Hubble Telescope and the Endeavor is on call to rescue the astronauts on the Atlantis in case they get stranded in space.  Stranded in Space..... sounds like an idea for a new reality show.
