BUZZ Aldrin has tweeted from his hospital bed in Christchurch today after he had to be evacuated from the South Pole with fluid in the lungs.
The former astronaut who was the second man to walk on the moon, was visiting Antarctica as a tourist when he fell ill.
He was flown to Christchurch from McMurdo Station and immediately taken to hospital yesterday.
This morning the 86-year-old tweeted that he had a surprise visitor from a long-time friend NASA deputy administrator Dava Newman.
Aldrin posed in photographs with Newman for the tweet.
His manager Christina Korp posted on Twitter yesterday that Aldrin made it to the South Pole before he was flown out.
Earlier Korp tweeted that Aldrin had fluid in his lungs, but was recovering in hospital after a "gruelling" 24-hour flight.
In a statement on Aldrin's website, it said he was "responding well to antibiotics" and his condition is stable.
Aldrin was on a sightseeing tour with his son Andrew, according to the Associated Press. The tour group departed Cape Town, South Africa on Tuesday.
