Today, SpaceX simultaneously fired up all 27 engines on its new massive Falcon Heavy rocket [www.pscp.tv] — a crucial final test for the vehicle before its first flight in the coming weeks. An hour after the test, SpaceX CEO Elon Musk confirmed that the test was good [twitter.com], and that the Falcon Heavy will launch in “a week or so.” When SpaceX gives an official target day and time, it’ll be the first time a definitive launch date has been given for the rocket’s inaugural voyage, a flight that was initially promised to happen as early as 2013.
