Is that the smell of rocket fuel in the air, or customer excitement?

The reported 600+ customers waiting in line for a trip to space aboard SpaceShipTwo (nickname: Enterprise) surely must have been excited when the suborbital spaceship successfully sailed through another powered flight test today (Thursday).

“SS2 has successfully completed another supersonic rocket-powered test flight! Hit our planned duration, altitude, and speed,” Virgin Galactic wrote on Twitter.

SpaceShipTwo also tested a “feathering” system that it has on board to assist with controlled re-entry. It allows the entire tail of the spaceship to rotate up to about 65 degrees, which Virgin says allows fine control of the attitude as the spacecraft comes back to Earth. “The feather configuration is also highly stable, effectively giving the pilot a hands-free re-entry capability, something that has not been possible on spacecraft before,” Virgin said of the system on its website.

The test, which started at about 8 a.m. Mojave time, saw the WhiteKnightTwo carrier aircraft take off from the Mojave Air and Space Port carrying SpaceShipTwo underneath. At 46,000 feet, pilots Mark Stucky and Clint Nichols released their spacecraft from the carrier and turned on the rocket motor for a 20-second burn. They climbed as high as 69,000 feet at a maximum speed of Mach 1.43, or 1.43 times the speed of sound.

“The main progress with this test is that we deployed the full expansion (up and down) of the feather mechanism at a high altitude, alongside testing the rocket motor performance,” wrote Virgin founder Richard Branson on his blog. “This feather mechanism was the key innovation that enabled us to get into the space program in the first place. It acts like a giant shuttlecock and slows the spaceship up as it comes back into the earth’s atmosphere.”

Branson also described Thursday’s test — the second powered flight for SpaceShipTwo, which did its first in April — as “the highest commercial winged vehicle [flight] in history.”

Reports say Branson and some members of his family will be on the first test flight. Should that go to plan, there is a parade of celebrities and ordinary citizens to come. Read more about SpaceShipTwo’s expected flight profile here.
