SpaceX just sent a press release with an update on the Falcon 9. They successfully did a 5-engine test. They also mentioned the next Falcon 1 attempt will be late June "or July," presumably meaning "late June or early July," but you never know. :-)
Here's the full text. This isn't on their web page yet, the last I looked: McGregor TX – Space Exploration Technologies Corp. (SpaceX) conducted the first five-engine firing of its Falcon 9 medium to heavy lift rocket at its Texas Test Facility outside McGregor on Thursday, May 29. At full power the engines generated almost half a million pounds of force, and consumed 1,750 lbs of fuel and liquid oxygen per second. This five engine test again sets the record as the most powerful test yet on the towering 235-foot tall test stand. The test of the five Merlin 1C engines, arranged in a cross pattern like the Saturn V moon rocket, is the last step before firing the full complement of nine engines, scheduled for this summer. With all engines operating, the Falcon 9 generates over one million pounds of thrust in vacuum - four times the maximum thrust of a 747 aircraft. “This is the first time that we’ve added more than one engine at a time, and all phases of integration and testing went smoothly,” said Tom Mueller, Vice President of Propulsion for SpaceX. “As with previous tests, we saw no unexpected interactions between the engines, and are on schedule for adding four more engines.” The first Falcon 9 will arrive at the SpaceX launch site at Cape Canaveral by the end of 2008. The next flight of SpaceX’s smaller Falcon 1 rocket is scheduled for late June or July of 2008. |

New press release from SpaceX about Falcon 9. Not posted on spacex.com yet. Basically good news, but still no concrete launch date.
--Greg SPACEX COMPLETES QUALIFICATION OF FALCON 9 FIRST STAGE TANK AND INTERSTAGE ________________________________________ McGregor, TX (July 29, 2009) – Space Exploration Technologies (SpaceX) announces the successful completion of qualification testing for the Falcon 9 launch vehicle first stage tank and interstage. Testing took place at SpaceX's Texas Test Site, a 300 acre structural and propulsion testing facility, located just outside of Waco, Texas. The first stage tank and interstage hardware were subjected to a proof test of 1.1 times the maximum expected operating pressure (MEOP), and a burst pressure proof test of 1.4 MEOP; qualifying both articles with a 1.4 factor of safety. The 1.4 factor of safety designation means that the first stage tank and the interstage can withstand 140 percent the maximum internal pressure expected during flight, and qualifies both pieces of hardware to meet human rating safety requirements, as defined by NASA. The first stage also passed this human rating milestone when subjected to structural bending tests. The testing regimen included over 150 pressurization cycles, exceeding the number of required life cycles by more than 100. In addition, the first stage and interstage were subjected to stiffness tests, maximum dynamic pressure loading and main engine cutoff conditions; all at expected values, as well as ultimate loads. "Falcon 9 continues to pass qualification testing in preparation for its first flight, scheduled for 2009," said Elon Musk, CEO and CTO of SpaceX. "All hardware was designed to be man-rated, and these tests confirm that SpaceX is one step closer to flying humans on the Falcon 9/Dragon system." Falcon 9's first stage and interstage also passed ground wind qualification tests, critical for when the vehicle is vertical on the launch pad at Cape Canaveral Air Force Station in Florida. Both components were designed, built and tested by SpaceX. |
