Watch the Falcon 9 launch from pad 39A

A new space weather observatory to be stationed a million miles from Earth has been enclosed inside the nose cone of a SpaceX Falcon 9 rocket for liftoff Sunday from Cape Canaveral.

SpaceX successfully launched an oft-delayed Falcon 9 rocket mission at 6:35 p.m. EST (2335 GMT) Friday after more than a week of delays caused by issues with super-chilled liquid oxygen propellant, a boat the strayed into restricted waters offshore Cape Canaveral, and extreme upper level winds. The experimental recovery of the first stage on an ocean-going barge was not a success.

The SpaceX Crew Dragon spacecraft that carried four astronauts to the International Space Station in November broke the record Sunday for the longest spaceflight by a U.S. crew vehicle, surpassing the 84-day mark set by an Apollo capsule on the final flight to the Skylab space station in 1974.
