SpaceX Completes Qualification of Falcon 9 First Stage Tank and Interstage

MCGREGOR, Texas--(BUSINESS WIRE)--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.

About SpaceX

SpaceX is developing a family of launch vehicles and spacecraft intended to increase the reliability and reduce the cost of both manned and unmanned space transportation, ultimately by a factor of ten. With the Falcon 1 and Falcon 9 vehicles, SpaceX offers highly reliable/cost-efficient launch capabilities for spacecraft insertion into any orbital altitude and inclination. Starting in 2010, SpaceX’s Dragon spacecraft will provide Earth-to-LEO transport of pressurized and unpressurized cargo, including resupply to the International Space Station (ISS).

Founded in 2002, SpaceX is a private company owned by management and employees, with minority investments from Founders Fund and DFJ. The SpaceX team now numbers nearly 800, with corporate headquarters in Hawthorne, California. For more information, please visit the company’s web site at www.spacex.com.
