Watch SpaceX's Falcon 9 launch its internet satellite payload (updated)

A SpaceX Falcon 9 is blasting into the skies today carrying Hisdesat's PAZ satellite, which will spend five and a half years carrying out radar and imaging work for the Spanish government and businesses. The launch, which uses a first stage booster previously used last August during the FORMOSAT-5 mission, will also have on board SpaceX's first demonstration satellites for its proposed satellite broadband service, which will be tested out before a full constellation launch over the next five years. Weather permitting, you'll be able to watch the launch live on PAZ's YouTube channel at 9AM EST (6AM PST), although a back-up window has been scheduled for Thursday, February 22nd, should things go awry -- since today's launch was initially slated for February 17th, that's not entirely unfeasible.
