SpaceX launches SES-12 communications satellite


SpaceX is preparing again to launch a Falcon 9 rocket carrying the SES-12 spacecraft after its Friday launch was canceled for additional testing. The first stage successfully landed during a flight in September, but was allowed to crash into the sea Monday because it's being discontinued.

Air Force weather officials are predicting a 70 percent chance of good launch weather for the four-hour June 4 launch window, starting at 12:29 a.m.

The rocket will carry the SES-12 satellite to orbit for the Luxembourg-based telecom company SES.

The first stage has flown once before, in September 2017, carrying the robotic X-37B space plane for the USA military. "We are going to be very rigorous in taking this rocket apart and confirming our design assumptions to be confident that is indeed able to be reused without taking apart", Musk said last month.

The 12,000-pound SES-12 spacecraft, built by Airbus Defence and Space, will deliver high-speed data to across Asia and the Pacific.

Monday's launch was the 56th flight of a Falcon 9 rocket, and SpaceX's 62nd launch overall. According to the mission's press kit, the Falcon 9 rocket's second stage will deploy the satellite 32 minutes and 14 seconds after liftoff.

The company recently revealed the new Falcon 9 Block 5.
