Because of the coronavirus, NASA's top official is asking space fans not to travel to Florida later this month to watch astronauts blast off from American soil for the first time since the retirement of the space shuttles in 2011.
"When we look back to the space shuttle launches, we had hundreds of thousands of people that would descend on the Kennedy Space Center," NASA Administrator Jim Bridenstine said in a pre-flight briefing. But, he noted, now is unfortunately not a good time for people to gather in large crowds.
"We're asking people not to travel to Kennedy, but to watch online or watch on your television at home," said Bridenstine, who confessed that it made him feel "sad" to have to say this.
The upcoming test flight is historic because the two astronauts, Robert Behnken and Douglas Hurley, won't be flying in a NASA vehicle. Instead, they'll go up inside a capsule created by SpaceX, the rocket firm founded by wealthy entrepreneur Elon Musk.
This first launch of people in a company-owned spacecraft, currently scheduled for 4:32 p.m. EDT on May 27, will be a milestone for both NASA and commercial spaceflight.
The astronauts are headed to the international space station, the orbiting outpost that has been continuously occupied for nearly 20 years. Since the shuttles retired, NASA has relied on Russian rockets to get crews to the station. With this upcoming launch, NASA will be starting to buy rides from companies that are operating a kind of space taxi service.
"We are going to launch American astronauts on American rockets from American soil," Bridenstine said. "We're going to do it here in the midst of the coronavirus pandemic. And I'm going to tell you that this is a high-priority mission for the United States of America. We, as a nation, have not had our own access to the international space station for 9 years."
Gwynne Shotwell, president and chief operating officer of SpaceX, said her company had worked closely with NASA for over a decade to make missions like this one a reality.
"The relationship with NASA has been extraordinary," Shotwell said. "NASA has been an extraordinary customer, an extraordinary partner, a mentor for us."
NASA's goal has been to let commercial space companies take over routine transportation to the station, while it focuses on venturing out farther. The agency is currently working at a breakneck pace to try to return humans to the surface of the moon by 2024, though many are skeptical that this target date is possible.
SpaceX was founded in 2002 with an expectation that it would someday launch people into space. Its robotic capsules have already been taking cargo to the station. But carrying astronauts is a completely different level of responsibility.
"I'm nervous now," Shotwell said. "I'll feel a little relief when they are in orbit; I will feel more relief when they get to station. And then, obviously, I will start sleeping again when they are back safely on the planet, planet Earth."
NASA has a long tradition of public openness regarding its launches, and Shotwell said SpaceX will be as transparent as it can and that the launch would be jointly webcast with NASA.
"I can't imagine a scenario where the public doesn't know what's going on with this particular mission," she said — even if they have to watch it from home.
Each of the astronauts has previously flown in space.
"It's probably the dream of every test pilot school student to have the opportunity to fly on a brand new spaceship, and I'm lucky enough to get that opportunity," Behnken said.
Hurley was the pilot on the final flight of the space shuttle program, and now he gets to fly on the first flight of this new phase in NASA's history.
"People are making a bit of a deal about it, and I certainly get that," he said. "I try not to think about it too much. While it's important, I think, to some degree, it's certainly not the focus of this mission."
Hurley said they'd been working on this commercial crew mission for years and that neither he nor his crew mate could have predicted that a pandemic would hit just when they were almost ready to fly.
"Obviously, we're very concerned. I'm concerned from a global-type concern, all the way down to, obviously, our families," he said, noting that they had continued to train and travel, but that the staff of NASA and SpaceX had done a tremendous job of keeping them safe.
He hoped the test flight might give people a little break from thinking about the coronavirus or a sense of hopefulness during a difficult time.
"We just want everybody to be safe," Hurley said. "We want everybody to enjoy this and relish this moment in U. S. space history, but the biggest thing is that we just want everybody to be safe and enjoy it from a distance."
