Atlantis is trending on the 135^th and final launch of the 30-year old space shuttle program. 

 Hundreds of thousands gathered at Florida's Kennedy Space Center to watch the shuttle begin its 12-day resupply mission to the International Space Station.  When it returns to earth, Atlantis will join Discovery and Endeavor in retirement.

Private companies and Russia's Soyuz spacecraft will take future cargo and astronauts to and from the space station, as NASA plans to devote its resources to unmanned deep-space exploration of asteroids and Mars.
