The mission patch for SpaceX's fifth operational space station resupply flight, a mission that will feature an unprecedented attempt to autonomously land the first stage of the Falcon 9 booster on a remotely-operated barge stationed east of Jacksonville. The test is a major step in the company's long-range plans to reduce launch costs by recovering and reusing rocket hardware. SpaceX<\/p>\n

SpaceX engineers made final preparations Monday for the planned Tuesday launch of a Falcon 9 rocket carrying a Dragon cargo ship loaded with more than 5,200 pounds of supplies, equipment and science gear bound for the International Space Station. But the launch attempt was aborted shortly before the scheduled liftoff. <\/p>\n
The next target time is Friday at 9 a.m. EST. <\/p>\n
The company was also going to attempt to land the booster's first stage on an off-shore barge, a key element in founder Elon Musk's long-range plans to lower costs by recovering, refurbishing and re-flying rocket hardware. <\/p>\n
\"We are extremely interested in the success of this flight in terms of getting cargo to the ISS,\" station Program Manager Mike Suffredini said. \"But as an agency, we're also extremely proud of our affiliation with SpaceX and very excited about the steps they take to further spaceflight in general and reduce the cost.\" <\/p>\n
Hans Koenigsmann, vice president of mission assurance for SpaceX, stressed that while the landing test was an important goal for the company's long-range plans, \"the main mission is absolutely to get cargo to the station and to make sure the station's supply (chain) is steady and stable and reliable.\" <\/p>\n
Running three weeks late because of now-resolved problems encountered during an engine test firing last month, the 208-foot-tall Falcon 9 was scheduled for liftoff from complex 40 at the Cape Canaveral Air Force Station at 6:20:29 a.m. EST (GMT-5) Tuesday, roughly the moment Earth's rotation moves the booster into the plane of the space station's orbit. Forecasters predicted a 70 percent chance of acceptable weather. <\/p>\n
It will be the company's fifth operational resupply mission under a $1.6 billion contract with NASA calling for 12 flights. It will be the first U.S. station supply flight since an Orbital Sciences Antares booster exploded seconds after liftoff Oct. 28, destroying a Cygnus cargo ship making the company's third flight under a separate $1.9 billion contract. <\/p>\n
Orbital's Antares rocket is now grounded pending a switch to different engines, leaving SpaceX as NASA's only provider of U.S.-based resupply services. The Russians also launch supplies using unmanned Progress cargo ships and larger Japanese HTV supply ships fly once every year or so. Three Progress launches are planned between now and early August, along with an HTV launch on Aug. 17. <\/p>\n
