NASA's acting administrator Robert Lightfoot Jr. requested the review back in February when he announced the agency's intention to add the crew to its 2018 launch. "I know the challenges associated with such a proposition," he wrote in a memo to NASA employees, "like reviewing the technical feasibility, additional resources needed, and clearly the extra work would require a different launch date." In April, the launch date was pushed back to 2019 due to technical problems.

Whether NASA or the Trump administration will take the recent study into account or not is still up in the air, according to a Bloomberg source. Still, adding a human crew to a potentially catastrophic maiden voyage like this can only increase the chances of a national tragedy, which would definitely slow down the current rush to return to space.
