Video: SpaceX Falcon 9 countdown aborted

Forecasters predict mostly clear skies, light winds and comfortable temperatures for Sunday’s launch of a Falcon 9 rocket with a NOAA satellite designed to warn of solar storms that could disrupt navigation and communication technology on Earth.

SpaceX will kick off a busy 2015 calendar playing catch-up, with liftoff of a Dragon supply ship for the International Space Station set for Tuesday after a delay from December.

Officials from SpaceX, NOAA, NASA and the U.S. Air Force hold the prelaunch news conference for Falcon 9 rocket launch of the Deep Space Climate Observatory.
