In June, two NASA astronauts, Suni Williams and Butch Wilmore, set out for what was expected to be an eight-day trip to the International Space Station.

On Wednesday, around six months and several spacecraft malfunctions later, they donned Santa Claus hats and wished their families the best from hundreds of miles above sea level as their tenure, which is likely to keep them in Earth’s orbit for at least two more months, stretched on.

Williams, 59, and Wilmore, 61, had a chance to participate in the long, strange tradition of celebrating the holidays in space, which began in 1968 when the Apollo 8 astronauts read verses from the Book of Genesis while broadcasting a video of the lunar surface to roughly 1 billion viewers.

A NASA spokesperson said the Starliner astronauts, along with their five fellow crew members, were spending the holidays “enjoying the view of Earth” and “privately communicating with their families” via video call and email.

Williams and Wilmore both celebrate Christmas.
