SpaceNews has an update on Virgin Galactic’s progress in testing SpaceShipTwo Unity.
Speaking at the International Symposium for Personal and Commercial Spaceflight here Oct. 10, George Whitesides, chief executive of Virgin Galactic, said he expected at least one more powered flight test of the vehicle before the end of this year.
“We’re entering into the next phase of our test flight program,” he said. “The next phase of flight will entail longer burns and higher duration, and that’s exciting for the team.”
Not all of those flights, though, will involve flights that go higher and faster. “We’ll do a variety of different things as we expand the envelope and try to understand abort scenarios and other things,” he said. “We have a lot of work still to go, but we’re making good progress.”
You might recall that the previous test flight in July the suborbital vehicle fired its engine for 42 seconds and reached an altitude of 170,800 ft, which are both records for the program.
