Q&A with Matt Desch, CEO of Iridium (members only)

After an exhaustive investigation, SpaceX engineers have identified the most likely cause of the spectacular explosion of a Falcon 9 rocket during a pre-launch test Sept. 1 that destroyed the booster and its $195 million satellite payload, the company announced Monday.

Two days after lifting off from Florida’s Space Coast, a Dragon cargo capsule packed with more than 6,400 pounds of research experiments and crew supplies arrived at the International Space Station on Wednesday. Astronaut Jack Fischer used the station’s robotic arm to grapple the supply ship at 6:52 a.m. EDT (1052 GMT).

Carrying the ambition of an entrepreneur with a passion for connecting the world, a half-dozen satellites lifted off Wednesday aboard a Soyuz rocket from the edge of the Amazon jungle in South America to kick off a series of at least 21 planned launches to deploy OneWeb’s global Internet network.
