In parallel developments within the space tourism sector, Virgin Galactic’s first new Delta-class spaceplane departed from its Arizona manufacturing facility on Wednesday, bound for Spaceport America in New Mexico. 1 This transfer positions the vehicle for upcoming test flights that will precede its intended commercial operations. 1 The company projects that the first commercial spaceflight using this new fleet could commence as early as the second quarter of 2027. 1 These updates come after Virgin Galactic’s previous-generation spacecraft, VSS Unity, concluded its commercial flight operations in 2024. 1
