Virgin Galactic’s SpaceShipTwo rocket plane crossed its 50-mile-high space boundary over New Mexico for the first time today, after months of challenges.
The trip by VSS Unity marks the first time a spacecraft has been launched so high from a New Mexico spaceport. Unity passed the 50-mile mark twice during tests at California’s Mojave Air and Space Port, in 2018 and 2019. Since then, the plane and its WhiteKnightTwo carrier airplane, dubbed VMS Eve, have been transferred to their operational home base at New Mexico’s Spaceport America.
“Today’s flight sees New Mexico become the third U.S. state to launch humans to space,” after Florida and California, Virgin Galactic said in a post-mission press release.
Virgin Galactic goes with the U.S. Air Force’s 50-mile definition for the boundary of space — rather than the internationally recognized 100-kilometer (62-mile) boundary, known as the Karman Line.
Today’s flight followed the standard profile for a SpaceShipTwo trip: The twin-fuselage Eve made an airplane-style takeoff from Spaceport America with Unity bolted to its underbelly. Around the target altitude of 44,000 feet, Unity was released from its mothership and fired up its hybrid rocket engine to rise spaceward.
Test pilots Dave Mackay and CJ Sturckow guided Unity to its peak altitude of 55.45 miles, cheered on by Virgin Galactic founder Richard Branson and other VIPs who gathered at Spaceport America.
