Follow the key events of the Falcon 9 rocket’s ascent into space from Cape Canaveral with the ABS 2A and Eutelsat 117 West B communications satellites.



Launch is set for 10:29 a.m. EDT (1429 GMT) on June 15 from Cape Canaveral’s Complex 40 launch pad. The satellites will be deployed in a supersynchronous transfer orbit, but SpaceX and the customers have not disclosed the exact target orbit parameters

Partly cloudy skies and balmy temperatures are forecast for Wednesday morning's launch of a Falcon 9 rocket from Cape Canaveral.


There is an 80 percent chance of acceptable conditions in the official launch forecast issued Tuesday by the U.S. Air Force's 45th Weather Squadron.


Liftoff is set for 10:29 a.m. EDT (1429 GMT) at the opening of a 44-minute launch window.


"On launch day, stronger and deeper southwest flow will delay the development and inland progression of the East Coast Sea Breeze until after the end of the morning launch window," the Air Force weather team wrote in Tuesday's forecast. "During the launch window, light southwest winds will allow for cumulus development over the Spaceport due to strong surface heating. The primary weather threat remains cumulus clouds."

The Falcon 9 is loaded with two Boeing-built communications satellites for Asia Broadcast Satellite and Eutelsat.


Scattered clouds are in the forecast at 2,500 feet at launch time, with southwest winds of 10 to 15 mph. The temperature will be around 87 degrees Fahrenheit.

20:34 Static fire update 



Technicians planned to attach two Boeing-built communications satellites to a SpaceX Falcon 9 rocket Monday, a day after launch controllers fueled the booster and fired its nine Merlin first stage engines in a key preflight test

The two-stage Falcon 9 rocket completed the static fire test Sunday at Cape Canaveral’s Complex 40 launch pad, throttling up its main engines to 1.5 million pounds of thrust for a few seconds to verify the vehicle’s readiness for flight.

SpaceX conducted the static fire test without the mission’s two satellite passengers on-board. Workers planned to return the rocket to its hangar and mate the two spacecraft, owned by Asia Broadcast Satellite of Hong Kong and Paris-based Eutelsat, to the rocket as soon as Monday.
