Space Shuttle Atlantis is up and away Monday heading towards the International Space Station on its' last trip of the year. The shuttle blasted off just after 1pm with six astronauts and a full load of spare parts on board. It is scheduled to reach its' orbiting outpost on Wednesday. The supply run is designed to keep the space station operating smoothly for years to come. The astronauts on the mission will be in space through Thanksgiving and the crew is expected to carry out three spacewalks during the 11-day mission. This is NASA's last shuttle flight for 2009 and one of only six remaining.
