SpaceX has postponed a Falcon 9 launch planned for this evening. The rocket was to have launched the AsiaSat6 satellite.
Early reports are that engineers need more time to review data from a failed test flight last week of its Falcon 9R reusable test vehicle in McGregor, Texas. The vehicle was blown up in flight after it suffered an anomaly. The Falcon 9 launch could be rescheduled for sometime next week.
Update: NASASpaceflight.com reports that SpaceX has provided no official reason for the delay. However, it reports that “engineers had been working on a helium leak throughout the past 24 hours or so.” That problem had been resolved with the replacement of two valves, but Elon Musk apparently then called a scrub to allow engineers to check the health of the vehicle. It’s not clear why.
Falcon 9 launches have been dogged by helium leaks this year. Reliable reports say the company brought helium tank production in house earlier this year.
