WATCH LIVE: SpaceX Polaris Dawn First All-Civilian Spacewalk

The world's first all-civilian spacewalk is still scheduled to take place this morning but it has been slightly delayed. SpaceX's Polaris Dawn mission launched four people into orbit Tuesday morning with the goal of making the world's first private spacewalk.

The liftoff from Cape Canaveral sent the Polaris Dawn into a record-high orbit above the Earth, to altitudes not seen by any astronaut since the Apollo missions of the 1970s.

The historic spacewalk is now expected to get underway just before 6am Eastern.
