Space station astronaut Reid Wiseman, preparing to return to Earth this weekend after 165 days in orbit, said commercial spaceflight represents the “next breakthrough” in aerospace technology, and that he hopes Virgin Galactic can ultimately turn that dream into reality despite the fatal crash of the company’s SpaceShipTwo rocket plane.

NASA held a pre-launch briefing for the Parker Solar Probe mission on Thursday, August 9, 2018, at the Kennedy Space Center.

The investigation into a dramatic Falcon 9 rocket explosion earlier this month at Cape Canaveral has determined a “large breach” in the launcher’s upper stage helium pressurization system led to the destruction of the booster and its $200 million satellite payload, SpaceX said Friday.
