Q&A with Elon Musk, SpaceX’s founder and CEO

A Falcon 9 rocket aborts its lift off at the final moment on February 28, 2016, as seen from the press site at Cape Canaveral Air Force Station. The rocket was supposed to launch the SES 9 communication satellite and had already been delayed by fueling problems and a boat that strayed into the launch danger area off shore.

The Starlink 17-5 mission will add another 24 broadband satellites to the company’s constellation of more than 8,100 currently in orbit. SpaceX is targeting liftoff from pad 4E at 9:26 a.m. PDT (12:26 p.m. EDT / 1626 UTC).

Watch Falcon 9 lift off from Kennedy Space Center launch pad 39A on a space station resupply mission. The rocket’s first stage then returned to land at neighboring Cape Canaveral Air Force Station.
