Q&A with Martin Halliwell, chief technology officer at SES

SpaceX’s Falcon 9 rocket will go from Cape Canaveral to low Earth orbit in 10 minutes Friday with a Dragon capsule heading for the International Space Station carrying nearly 7,000 pounds of supplies and experiments.

A commercial SES communications satellite on the way to an operating post over the Americas rode into orbit from French Guiana aboard a Russian Soyuz rocket Thursday, embarking on a mission to help airline travelers stay connected and improve air navigation over the United States.

Watch a time-lapse video of the 229-foot-tall (70-meter) Falcon 9 rocket being lifted into place on pad 39A in readiness for the launch of the SES 10 communications satellite. This will be a major milestone for SpaceX as it will mark the first time a flown Falcon 9 first stage has been reused.
