Virgin Galactic soars again with new spacecraft’s first flight.
Beginning a series of intense testing to validate its design, Virgin Galactic's VSS Unity performed its first free flight earlier this week. The spaceship was delivered to an altitude of 50,000 feet by its mothership – the VSS Eve – before gliding back to the runway at the Mojave Air and Space port.
This first test saw the craft fly no faster than Mach 0.6, and with empty propellant tanks. Future tests in the series will see the VSS Unity fly at faster speeds with different weight – simulating different flight profiles with fully loaded and partially empty fuel tanks.
Friday's test marked the first crewed test flights since Virgin Galactic's first space plane – the VSS Enterprise – broke apart midflight in October, 2014, killing one of its two crewmembers. Modification's to the vehicle's control system were implemented to prevent the manual feathering – or pivoting – of its tails prematurely, which caused the 2014 crash. Test flights using the vehicle's rocket engine will occur in 2017.
