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.

A little while ago the SpaceX Dragon spacecraft blasted off atop a Falcon 9 rocket from Cape Canaveral in its CRS-16 (Cargo Resupply Service 16) mission, also referred to as SPX-16. After just over ten minutes it separated successfully from the rocket’s last stage and went en route. This is the 16th mission for the Dragon spacecraft to resupply the International Space Station with various cargoes and then return to Earth, again with various cargoes.

At a press conference, NASA administrator Jim Bridenstine announced the new plans for the return to the Moon with the inclusion of a number of private companies that will have the chance to provide their services to send various types of payload. The program called Commercial Lunar Payload Services (CLPS) could start as early as 2019 and represents a first step towards a long-term goal, that is to establish a permanent presence on the Moon with an eye to Mars.
