The second man to walk on the moon has been evacuated from Antarctica to New Zealand suffering respiratory problems.
Buzz Aldrin is in Christchurch Hospital where he is being treated for fluid on his lungs after a midnight mercy dash from the icy continent.
His manager Christina Korp, who travelled alongside the stricken former astronaut, described the ordeal as a "gruelling 24 hours" but said Aldrin was now recovering well in New Zealand.
She posted pictures of him giving the thumbs up inside an ambulance and smiling from his hospital bed.
Aldrin was part of a tourist group with luxury adventure tour company White Desert.
