It was yesterday morning in California when Virgin Galactic’s SpaceShipTwo spaceplane called VSS Unity took off connected to its White Knight Two mother ship from the Mojave Air and Space Port. Once reached 15,000 meters (about 43,000 feet) above sea level, VSS Unity was dropped and its engine brought it to an altitude of 82.7 kilometers (about 51.4 miles), below the 100 kilometers (62 miles) of the Kármán Line which officially marks the border with the space but above the 80 kilometers (50 miles) considered by some institutions as that borderline.
