SpaceX Completes Rocket Explosion Investigation. Will Resume Rocket Launches Starting January 8

Space.com: SpaceX Completes Rocket Explosion Investigation, Aims for Jan. 8 Launch

WASHINGTON — SpaceX plans to resume Falcon 9 launches on Jan. 8 after completing the investigation into the pad explosion that destroyed another Falcon 9 four months ago.

In a statement posted on the SpaceX website Jan. 2, the company said the explosion was caused by the failure of one of three helium tanks, known as composite overwrapped pressure vessels (COPVs), inside the liquid oxygen tank in the rocket’s second stage. The company had previously indicated that a COPV failure was a leading cause of the accident.

Each COPV is made of an aluminum liner surrounded by a carbon composite overwrap. Other COPVs recovered from the Falcon 9 showed buckling of their liners, although what caused the buckling isn't stated.

Moon Dreams The Americans May Still Go To The Moon Before The Chinese

From The Economist:

WHEN America’s space agency, NASA, announced its spending plans in February, some people worried that its cancellation of the Constellation moon programme had ended any hopes of Americans returning to the Earth’s rocky satellite. The next footprints on the lunar regolith were therefore thought likely to be Chinese. Now, though, the private sector is arguing that the new spending plan actually makes it more likely America will return to the moon.

From MSNBC:

Twin-fuselage White Knight Two goes through test at Mojave airport

A carrier aircraft designed to be the first stage of a commercial spaceline system made its maiden test flight Sunday at the Mojave Air and Space Port in California.

Designed by Scaled Composites, the huge and unique White Knight Two mothership rolled down the runway and muscled itself into the air using four Pratt and Whitney PW308A turbofan engines. The White Knight Two flew for about an hour, departing the runway at roughly 8:17 a.m. PT, safely touching down at the Mojave airport at approximately 9:17 a.m. PT.

"It's a big day," said Stuart Witt, general manager of Mojave Air and Space Port. "I think it's a real reflective time. When everybody's looking for a bailout, there are still people that are doing something for a much larger reason," he told Space.com.
