Video: Last minute technical problem scrubs Falcon 9 launch

This is the first out of at least eight planned launches supporting the broadband internet satellite constellation in November. Liftoff from pad 40 at Cape Canaveral Space Force Station is scheduled for 8:31 p.m. EST (0131 UTC).

Ten more satellites for Iridium’s commercial communications network flew into orbit Friday aboard a Falcon 9 rocket from Vandenberg Air Force Base in California, raising the total number of upgraded Iridium spacecraft launched to 50 and clearing the way for liftoff of a SpaceX supply ship Monday from Cape Canaveral to the International Space Station.

A Falcon 9 rocket is moved into the position for a static test firing of its nine Merlin 1D engines. This time lapse video runs at 20 times normal speed.
