Q&A with Greg Wyler, founder and chairman of OneWeb (members only)

SpaceX is preparing for the next launch of a Falcon 9 rocket, set for blastoff from the Kennedy Space Center in Florida with the EchoStar 23 television broadcast satellite destined to cover Brazil. The rocket’s static fire test, a major milestone in any SpaceX launch campaign, was performed Thursday.

A European Ariane 5 rocket fired into a gloomy sky Thursday over French Guiana and streaked into space from the tropical launch base with 2.9 million pounds of thrust from two solid rocket boosters and a hydrogen-fueled Vulcain 2 main engine.

The world’s most powerful operational rocket flashed to life at 2:30 a.m. EDT (0630 GMT) Tuesday and climbed into a moonlit summer sky from pad 39A at NASA’s Kennedy Space Center in Florida, the same site where the Apollo 11 astronauts left Earth for their historic moon landing nearly 50 years ago.
