NASA confirmed on Friday that Jeanette Epps, a former CIA technology intelligence officer selected as an astronaut in 2009, will finally launch into space in early 2024 on a SpaceX flight to the International Space Station. The crew assignment comes six years after NASA pulled Epps from what would have been her first spaceflight, just months before her scheduled launch to the space station on a Russian Soyuz spacecraft.

The removal of Epps from the Soyuz mission in 2018 raised a lot of questions. It's not the first time NASA has pulled an astronaut off of space missions soon before launch, but it's usually for medical reasons, like an illness or an injury.

That wasn't the case for Epps, who was replaced by a backup crew member on the Soyuz flight in 2018. NASA never publicly stated a reason for the crew change. Some people outside the agency theorized Epps might have been removed from her flight for political or racial reasons—she would have become the first Black astronaut to fly a long-duration stint on the space station—but Ars has reported that did not appear to be the case .

Nearly six years ago the European Space Agency surprised its longtime spaceflight partners at NASA, as well as diplomatic officials at the White House, with an announcement that some of its astronauts were training alongside Chinese astronauts. The goal was to send European astronauts to China's Tiangong space station by 2022.

"We were welcomed as colleagues and friends by the ‘taikonauts’ and the instructors," said European astronaut Samantha Cristoforetti at the time. "Language and cultural differences are obviously a challenge, but also adds value, as we are all focused on the common goal of space exploration."

European astronauts did not fly to the Chinese space station in 2022, however, even though China completed its construction before the end of the year. In fact, Europeans are now unlikely ever to do so, even as the Tiangong facility flies for another decade, or longer, in low-Earth orbit.
