Launch Slip for Turkmenistan
21MAR2015
Shotwell says an issue with helium tanks on the Falcon 9 v1.1 has prompted SpaceX to delay a March 21 commercial mission for the government of Turkmenistan. The company now hopes to launch Turkmensat-1 and an International Space Station (ISS) cargo resupply mission for NASA before April 17. “We were doing some component stress testing over the weekend and were a little uncomfortable with the helium bottle pressure onboard. It passed inspection, but now is not the time to have an issue in flight, so we’re going to go in and do some work on those bottles, so that will delay the flight.”
Sources said SpaceX is still analyzing data to determine the root cause of the leak, and institute corrective actions, out of concern the high-pressure helium tanks might leak or fail in flight.
