SpaceX CRS-7
SpaceX CRS-7 was a private American rocket cargo resupply mission to the International Space Station, contracted to NASA, which launched and failed on June 28, 2015. It disintegrated 139 seconds into the flight after launch from Cape Canaveral, just before the first stage was to separate from the second stage. It was the ninth flight for SpaceX's uncrewed Dragon cargo spacecraft and the seventh SpaceX operational mission contracted to NASA under a Commercial Resupply Services contract. The vehicle launched on a Falcon 9 v1.1 launch vehicle. It was the nineteenth overall flight for the Falcon 9 and the fourteenth flight for the substantially upgraded Falcon 9 v1.1.
==Launch history==
In January 2015, the launch was tentatively scheduled by NASA for no earlier than June 13, 2015. This was adjusted to June 22, 2015, then moved forward to June 19, 2015 and adjusted again to June 26, 2015.〔(【引用サイトリンク】url=http://www.spaceflightnow.com/tracking/index.html )〕 Subsequently, the launch had been rescheduled to June 28, 2015 at 14:21:11 UTC, from Cape Canaveral LC-40. The launch was scheduled to be the third controlled-descent and landing test for the Falcon 9's first stage. It would have attempted to land on a new autonomous drone ship named ''Of Course I Still Love You'' – named after a ship in the novel ''The Player of Games'' by Iain M. Banks. The spacecraft was planned to stay in orbit for five weeks before returning to Earth with approximately of supplies and waste.〔
