Crew-1 on pad

WASHINGTON — NASA has postponed the launch of its first operational commercial crew mission by a day, citing weather conditions for the recovery of the Falcon 9 first stage rather than at the launch site itself.

NASA said Nov. 13 that it was pushing back the Crew-1 launch by one day, to Nov. 15. Liftoff from the Kennedy Space Center’s Launch Complex 39A is scheduled for 7:27 p.m. Eastern.

In a tweet, NASA Administrator Jim Bridenstine said that “onshore winds and recovery operations” prompted the one-day delay. That was an apparent reference to conditions at the location in the Atlantic Ocean where the Falcon 9 first stage will land on a droneship. NASA plans to use that stage for the next commercial crew mission, Crew-2, launching in the spring of 2021.

Weather for the launch itself was favorable, with forecasts projecting a 70% chance of acceptable weather for a Nov. 14 launch, decreasing to 60% on Nov. 15. Those probabilities, though, only reflect launch weather conditions and do not take into account upper-level winds or conditions at both the booster recovery site or abort locations in the Atlantic.

At a press event earlier Nov. 13, Bob Cabana, director of the Kennedy Space Center, said teams were working “no serious issues” technically with the rocket and Crew Dragon spacecraft.

Crew-1, billed as the first operational commercial crew mission, will carry NASA astronauts Mike Hopkins, Vic Glover, Shannon Walker and JAXA astronaut Soichi Noguchi to the International Space Station for a six-month stay. A launch Nov. 15 would have the capsule docking with the station around 11 p.m. Eastern Nov. 16.

Bridenstine, at the media event, defended the use of “operational” even though this is only the second flight of the Crew Dragon with astronauts on board. “When we think about flights to space, we take all of them with great precaution. We take them very seriously,” he said. “Every bit of attention that we have on a test flight we also have on operational flights.”

That event also discussed another issue tangentially related to the launch: comments by SpaceX Chief Executive Elon Musk on Twitter early Nov. 13 where he said he had received conflicting test results, both positive and negative, for COVID-19. Musk also reported having mild cold-like symptoms.

“When someone tests positive for COVID here at the Kennedy Space Center and across NASA, it is our policy for that person to quarantine and self-isolate, so we anticipate that will be taking place,” Bridenstine, adding that he expected SpaceX to do any contract tracing. It was unclear if Musk has recently been at the center, and agency officials said the Crew-1 astronauts have been in quarantine and not in contact with Musk.
