SpaceShipTwo Flight Test Scheduled for this Morning

Word has it that Virgin Galactic has scheduled the fourth glide flight of SpaceShipTwo Unity this morning in Mojave. The test will be the first for Richard Branson’s suborbital space plane in more than two months.

Cell service permitting,  I will be providing coverage of the test at www.twitter.com/spacecom

On the test card for today is deployment of the new spaceship’s redesigned feather system, which re-configures the ship when it returns from space. Unity will be hauled aloft to an altitude of about 50,000 feet by the WhiteKnightTwo carrier aircraft Eve.

The premature deployment of the feather system during powered ascent led to the destruction of the first SpaceShipTwo Enterprise during a flight test on Oct. 31, 2014. Scaled Composites pilot Mike Alsbury died in the accident. Virgin Galactic has added a mechanism to the feather system to prevent premature deployment of the feather.

The weather forecast looks good for the flight, with sunny skies and low surface wind speeds.

There’s a NOTAM (Notice to Airmen) for the operation of an unmanned aerial system (UAS) at the spaceport from 6 a.m. to noon. It’s not clear who will be operating the system, but it wouldn’t surprise me if Virgin Galactic is aiming to capture video of the flight from the air.

The six-hour period for UAS operations overlaps with the likely window for a SpaceShipTwo flight test. So, it is unlikely that this is a coincidence.
