Buzz Aldrin is being evacuated from the South Pole, the National Science Foundation (NSF) confirmed Thursday morning.
The 86-year-old astronaut was said to be "ailing" and will be flown to New Zealand. He was the second man to walk on the moon and has been a strong advocate for continued space travel and research since.
Aldrin was visiting the U.S. Antarctic Program's research center as a tourist. He is in stable condition, the BBC reports.
Here's Aldrin before his trip.
The cold did not seem to faze him -- he's BEEN TO THE MOON, people.
Some Twitter users were afraid Aldrin would be the latest 2016 celebrity death.
