Tourism
venture Virgin Galactic sent its spaceplane into space for the second time this
morning, qualifying all three people on the flight for their commercial
astronaut wings. One of those riders was Virgin Galactic’s first test
passenger, Beth Moses, the chief astronaut instructor at Virgin Galactic, who
flew along with the vehicle’s two pilots. She’s also Virgin Galactic’s first
female flyer.

Virgin
Galactic’s spaceplane, the VSS Unity, is designed to take passengers to the
edge of space where they can experience a few minutes of weightlessness. But up
until the end of last year, the vehicle had yet to breach Earth’s
atmosphere. That
changed in Decemberwhen Virgin Galactic made history by sending VSS Unity
to a height of 51.4 miles (82.7 kilometers), an altitude that many (but not
all) consider
to be the start of space.
For those
who adhere to that definition, it was the first time that people had launched
to space from the US since 2011. As a result, the two pilots of the December
flight received
astronaut wings from the Federal Aviation Administration in early February.

Today, the
company demonstrated that it was able to repeat that history-making flight
path, with another test out of Mojave, California. As usual, VSS Unity was
lofted to an initial altitude of around 45,000 feet by its huge carrier
aircraft, WhiteKnight Two, where it was then released into the air.
The two
pilots of this morning’s flight, Dave Mackay and Mike “Sooch” Masucci, ignited
the spaceplane’s engine and climbed to an altitude of 55.85 miles (89.9
kilometers), the highest the vehicle has gone yet. During the test, the vehicle
reached a top speed of three times the speed of sound — the fastest ever for
Virgin Galactic — before shifting its wings and gliding back to Earth to land
on a runway.
This was
the first time that VSS Unity carried three people, instead of just the two
pilots, to space. Moses rode along in the cabin of the spacecraft and got out
of her seat, in order to get a better understanding of the “customer cabin and
spaceflight environment from the perspective of people in the back,” according
to the company. Moses will be responsible for preparing future passengers for
what to expect on flights, and today’s flight will provide valuable input for
that. Her trip today also makes her the first woman to fly to space onboard a commercial
vehicle.
Just like
the December test, today’s flight also carried a number of research payloads,
arranged through NASA’s Flight Opportunity Program. Virgin Galactic also
included extra weight in the cabin of VSS Unity in order to better mimic the
weight commercial flights will have when they carry a few full passenger crews.
Today’s
flight marks the fifth powered flight test of VSS Unity, and Virgin Galactic
plans to continue with these flights throughout the year. Eventually, the
company will move to a new location in New Mexico called Spaceport America
where it will conduct its future commercial flights. An official date for that
move hasn’t been set yet. However, Virgin Galactic founder Richard Branson has
said he hopes to fly on VSS Unity by the summertime, potentially on the
anniversary of the Apollo 11 Moon landing in July.
