A proposal by Elon Musk’s SpaceX to fuel its rockets while astronauts are aboard poses safety risks, a group of space industry experts that advises NASA has told the U.S. space agency.
‘This is a hazardous operation,’ Space Station Advisory Committee Chairman Thomas Stafford, a former NASA astronaut and retired Air Force general, said during a conference call on Monday.
Stafford said the group’s concerns were heightened after an explosion of an unmanned SpaceX rocket while it was being fueled on Sept. 1.
