SpaceX has launched four astronauts to the International Space Station for NASA, less than two days after completing a flight chartered by millionaires.
It’s the first NASA crew comprised equally of men and women including the first Black woman making a long-term spaceflight, Jessica Watkins.
“This is one of the most diversified, I think, crews that we’ve had in a really, really long time,” NASA’s space operations mission chief Kathy Lueders said on the eve of launch.
The astronauts were due to arrive at the space station on Wednesday night, 16 hours after their pre-dawn lift-off from Kennedy Space Center. They will spend five months at the orbiting lab.
SpaceX has now launched five crews for NASA and two private trips in just under two years.
Elon Musk’s company is having an especially busy few weeks. It just finished taking three businessmen to and from the space station as NASA’s first private guests.
A week after the new crew arrives, the three Americans and German they are replacing will return to Earth in their own SpaceX capsule. Three Russians also live at the space station.
Both SpaceX and NASA officials stressed they are taking it one step at a time to ensure safety. The private mission that concluded on Monday encountered no major problems, they said, although high wind delayed the splashdown for a week.
The SpaceX capsules are fully automated — which opens the space gates to a broader clientele — and designed to accommodate a wider range of body sizes. At the same time, NASA and the European Space Agency have been pushing for more female astronauts.
The just-completed private flight was NASA’s first dip into space tourism after years of opposition. The space agency said the three people who paid $US55 million ($A77 million) each to visit the space station blended in while doing experiments and educational outreach.
They were accompanied by a former NASA astronaut employed by Houston-based Axiom Space, which arranged the flight.
“The International Space Station is not a vacation spot. It’s not an amusement park. It is an international laboratory, and they absolutely understood and respected that purpose,” said NASA flight director Zeb Scoville.
NASA also hired Boeing to ferry astronauts after retiring the shuttles. The company will take another shot next month at getting an empty crew capsule to the space station, after software and other problems fouled a 2019 test flight and prevented a redo last summer.
