The preliminaries are over. And now the moment of truth has arrived for Richard Branson’s Virgin Galactic.
Almost 3.5 years after SpaceShipTwo Enterprise broke up during a flight test on Halloween 2014, the company is scheduled to conduct the first powered flight of SpaceShipTwo Unity later this morning from the Mojave Air and Space Port in California. The test was preceded by seven glide flights.
I’ll be providing live updates on the flight on Twitter @spacecom.
SpaceShipTwo Flies: Virgin Galactic’s SpaceShipTwo Unity performed its seven glide flight this morning in Mojave. The flight appeared to go as planned based on what I could see from the ground and Virgin Galactic’s tweets; the space plane landed and rolled to a stop on runway 30. The pilots were Mark Stucky and Michael Masucci.
This is the seventh glide flight for Unity and the 37th glide test for the SpaceShipTwo program. Its predecessor, Enterprise, flew 30 glide and three powered flights before it broke up during its fourth powered flight on Oct. 31, 2014.
Virgin Galactic officials have said today’s test should be the final glide flight for Unity. If all went well, the next test will be powered.
UPDATE: Virgin Galactic has posted a description of today’s flight here.
SpaceX Scrubs: SpaceX scrubbed a static fire of the Falcon Heavy booster for the second time in as many days at NASA’s Kennedy Space Center. The company planned a 12- to 15-second firing of the 27 first stage engines of the heavy-lift rocket. No reason has been given for the scrub. Reports indicate that a third attempt is set for Friday. If the same schedule is maintained, the six-hour test window will open at 1 p.m. EST.
Delta IV Launch Set: United Launch Alliance is planning to launch a Delta IV booster with the NROL 47 reconnaissance satellite from Vandenberg this afternoon. The original launch time was set for 1 p.m. PST, but ULA says it is working a technical issue that will delay the launch until later. No new time as been set yet. The launch was scrubbed on Wednesday due to high winds.
UPDATE: Liftoff is now planned for 1:55 p.m. PST. Webcast commentary will start at 1:30 p.m. PST. UPDATE 2: Liftoff now at 2:05 p.m. PST.
Chinese & Indian Launches Scheduled: A Chinese Long March 3B rocket will launch two Beidou navigation satellites at approximately 2300 GMT (6 p.m. EST) today. The flight will be conducted from the Xichang Satellite Launch Center.
India’s PSLV booster will launch the Cartosat 2F remote sensing satellite from Satish Dhawan Space Center on Friday at 0358 GMT (10:58 p.m. EST on Thursday, Jan. 11). It will be the first PSLV launch since August when a failure of the payload shroud to separate doomed an IRNSS-1H navigation satellite to a fiery destruction.
A Long March 2D rocket is set to launch an unidentified satellite from Jiuquan on Saturday at approximately 0710 GMT (2:10 a.m. EST). This will be China’s third launch of the new year.
Finding My Virginity: The New Autobiography Richard Branson Portfolio Oct. 10, 2017 482 pages
On the morning of Oct. 31, 2014, a nightmarish vision that had haunted me for months became a real-life disaster in the skies over the Mojave Desert. SpaceShipTwo dropped from its WhiteKnightTwo mother ship, lit its engine and appeared to explode. Pieces of the space plane then began to rain down all over the desert.
The motor had exploded. Or the nitrous oxide tank had burst. At least that’s what I and two photographers – whose pictures of the accident would soon be seen around the world – thought had occurred as we watched the flight from Jawbone Station about 20 miles north of Mojave.
We really believed we had seen and heard a blast nine miles overhead, the photos appeared to show one, and it was the most plausible explanation at the time.
We were wrong. More than two days after the accident, the National Transportation Safety Board (NTSB) revealed that co-pilot Mike Alsbury had prematurely unlocked SpaceShipTwo’s feather system during powered ascent. The ship hadn’t blown up, it had broken up as the twin tail booms reconfigured the vehicle with the engine still burning at full thrust. (more…)
While Boeing and SpaceX move toward flying astronauts to the International Space Station this year, there are two other companies working on restoring the ability to launch people into space from U.S. soil.
Blue Origin and Virgin Galactic aren’t attempting anything as ambitious as orbital flight. Their aim is to fly short suborbital hops that will give tourists and scientists several minutes of microgravity to float around and conduct experiments in.
The morning of Dec. 3, 2016, began like so many others in Mojave. The first rays of dawn gave way to a brilliant sunrise that revealed a cloudless, clear blue sky over California’s High Desert.
This was hardly newsworthy. For most of the year, Mojave doesn’t really have weather, just temperatures and wind speeds. It had been literally freezing overnight; the mercury was at a nippy 28º F (-2.2º C) at 4 a.m. As for Mojave’s famous winds – an enemy of roofs, trees and big rigs, but the lifeblood of thousands of wind turbines that cover the landscape west of town – there really weren’t any. It was basically a flat calm.
At some point in the next six months, the Mojave Air and Space Port could experience something that not happened here in 13 long years: an actual spaceflight.
Richard Branson is predicting that Virgin Galactic’s SpaceShipTwo Unity could reach space on a flight test from Mojave by December. For once, his prediction does not appear to be based on unrealistic hopes, the need to reassure customers about delays, or a complete misunderstanding of what is happening on the ground here.
In other words, it’s actually plausible. Whether it will happen on that schedule…that’s another question. Flight test is notoriously unpredictable and very tough on timetables.
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.
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.
