Video: SpaceX Falcon 9 countdown aborted

The world’s most distant weather outpost is set for liftoff from Cape Canaveral on Sunday aboard a SpaceX Falcon 9 rocket, launching to a point a million miles from Earth to warn forecasters of solar storms that could disrupt global air traffic, satellite navigation and power grids.

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.

After waiting nearly two decades for dream to become reality, former Vice President Al Gore said Sunday the mission he fostered in 1998 — finally ready for launch this week — will have important scientific and social impacts in humanity’s relationship with Earth.
