National Aeronautics & Space Administration has been properly noncommittal on the idea of committing astronauts to SLS's first flight. It is, after all, a mammoth booster generating 8.8 million pounds of liftoff thrust to put 70 metric tons into low Earth orbit (where any flight to the moon or beyond would begin). NASA has said only that after discussions with the new administration, it is studying what opportunities "crew on first SLS" offers, and what it would take to accomplish the first step of pushing humans farther into space. Here, Jones discusses the risks of rushing a crew aboard the untried NASA vehicles.
