Watch the Falcon Heavy fire up its engines

Soaring into orbit in a rare middle-of-the-night launch from French Guiana, an Ariane 5 rocket took off at 0520 GMT (12:20 a.m. EST) Wednesday with a Eutelsat communications satellite to boost television capacity ahead of the Rio Olympics.

Blue Origin scrubbed the planned launch Tuesday of the company’s suborbital New Shepard booster from West Texas due to a “ground infrastructure issue,” and later said the flight would be pushed back to early 2019.

The Falcon 9 rocket’s main engines briefly ignited at launch pad 39A in a standard pre-launch test. This is the second time this booster has test fired its engines on a launch pad at Cape Canaveral.
