“After a slight delay, a used SpaceX Falcon 9 rocket is scheduled to make its second trip to space today (June 23) to orbit the first communications satellite for Bulgaria. The BulgariaSat-1 launch will mark the Falcon 9’s second flight this year, and may kick off a double-header with a Sunday SpaceX launch as well. You can watch the launch live online here at Space.com, courtesy of SpaceX. The rocket with pre-flown booster is set to launch from Kennedy Space Center’s historic Pad 39A during a window extending from 2:10 to 4:10 p.m. EDT (1810-2010 GMT). On Jan. 14, the company successfully launched and landed the booster while putting 10 communications satellites into low-Earth orbit for the Virginia-based company Iridium. This time, the booster will help loft Bulgaria’s communications satellite before landing again.”
