 Virgin Galactic Holdings Inc NYSE:SPCE said it is on track to begin space tourism flights from the second quarter of 2023, with fixes to its mothership complete and a change to its management team. The VMS Eve mothership is expected to enter ground tests next week and then begin flight tests to check the enhancements made after the New Mexico-based company was forced to delay its first commercial flights in September 2021 because of a possible malfunctioning component in its VSS Unity rocket.
