The curious collection of a slightly mad scientist
Although it still hasn’t reached space, Virgin Galactic’s SpaceshipTwo flew slightly longer and higher than it did on its first powered flight in April – and this time it also deployed a safety mechanism called feathering as it descended back through Earth’s atmosphere.
The launch began at approximately 8 am local time yesterday, when the company’s WhiteKnightTwo carrier aircraft took off from Mojave, California. Once it reached an altitude of 14 kilometres, the carrier released SpaceShipTwo to fly by its own rocket power.
The spaceship then broke the sound barrier, accelerating to Mach 1.43 and reaching a maximum altitude of 21 kilometres. The engine burn lasted 20 seconds. That’s 4 seconds longer and about 4 kilometres higher than last time, on SpaceShipTwo’s first flight.
The craft’s rockets will have to sustain a 70 second flight to reach space, but Virgin Galactic founder Richard Branson was excited nonetheless. “This is a giant step,” he wrote on his blog on Thursday. “Our spaceship is now the highest commercial winged vehicle in history!”
