In an attempt to cross the Antarctic unaided, British explorer Henry Worsley has died.
The 55-year-old called for help just 30 miles short of completing the trek. He had already traveled 913 miles across the South Pole, but struggled with a bacterial infection and dehydration.
With the expedition coming to an end, Worsley sent out one last message:
The 71 days alone on the Antarctic with over 900 statute miles covered and a gradual grinding down of my physical endurance finally took its toll today, and it is with sadness that I report it is journey's end -- so close to my goal.
After placing the call, Worsley was airlifted to Punta Arenas, Chile, where shortly after arrival he was pronounced dead. He had been traveling solo for 71 days before he succumbed to his illnesses.
Prince William commented on the loss and iterated that he and his brother, Prince Harry, were saddened by the news, adding, “He was a man who showed great courage and determination. We are incredibly proud to be associated with him.”
Worsley’s wife Joanna sent out this statement:
It is with heartbroken sadness I let you know that my husband Henry Worsley has died following complete organ failure; despite all efforts of ALE [Worsley's expedition team] and medical staff at the Clinica Magallanes in Punta Arenas, Chile.
This tweet, showing Worsley weathered and tired, was sent out three days before his death:
