NASA chief Jim Bridgestone this week explained the reason why the US space agency launched a security check of SpaceX and Boeing, which build space ships for astronauts, including their workplace culture and drug policies.
Although NASA initially declined to confirm media reports that the review was prompted by the appearance of SpaceX CEO, Elon Mask, on a recorded podcast in which he smoked jointly, Bridenstein concluded on Thursday, during a roundtable with journalists, it "was not useful ".
He added that he is the one who called for a security review, released on November 20, for the two companies in charge of building a spacecraft that would allow Americans to send people once again into space – a capacity that the United States lost in 2011 with retirement of the space shuttle program.
"We had a lot of conversations," Bridgestone quoted as telling the magazine Atlantic.
"I'll tell you that he (the muscle) is committed to security like everyone else, and he understands that this is not appropriate behavior, and you will not see it again."
Speaking later about AFP, Bridgestone said the review shows how seriously NASA takes the safety of its astronauts.
"The reality is, we are ready to launch US astronauts to US American-launched rockets for the first time since 2011, and we want to make sure that we have a cultural assessment, an assessment of the security of each of our providers," he said.
"If we look at the history of this, when accidents happened in the past, there has always been safety assessment by fact and includes things like leadership and culture and security of the organizations involved in the mission," he added.
"We did not want to wait until an accident, because we do not believe there will be an accident, but we wanted to make sure that we make that assessment early, not on that fact."
SpaceX is a NASA contractor from 2012, carrying supplies to the International Space Station on the cargo ship Dragon.
The following year, SpaceX is preparing for the first flight of the crew capsule of the Dragon, with two astronauts on the ship, which rose to the top of the Falcon 9 rocket.
An empty flight test is scheduled for January 7, 2019, from Cape Canaveral, Florida.
