The SpaceX CRS-7 rocket failed minutes after Sunday's launch, blowing up in mid-air. Just after T+2 minutes, when the craft's altitude was 32 km, its speed was 1 km/second, and its downrange distance was 30 km, its flight path apparently began curving downward. Three explosions then occurred. "There was an overpressure event in the upper stage liquid oxygen tank. Data suggests counterintuitive cause," SpaceX CEO Elon Musk tweeted. "The Falcon line has been a remarkably reliable launch vehicle," said Frost & Sullivan analyst Mike Jude.
