A busy day in space, so let’s get right to it:
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.
