"Wharton served as executive officer for the National Science Foundation's office of polar programs, participating in 11 expeditions to the Antarctic. He also was a visiting senior scientist at NASA headquarters in Washington, D.C."
Keith's note: I am profoundly saddened to hear of Bob's passing. I got to know Bob very well when he and I worked at the old Life Sciences Division at NASA Headquarters in the 1980s. Bob was an astrobiologist before the word had even been coined. He was an adventurer and a jack of all trades. Among other things, he spent a lot of time diving under Antarctic ice with Chris McKay and Dale Andersen and roaming the Antarctic dry valleys. He was also an avid climber and mountaineer. Bob and I went rock climbing several times. One trip in particular, to Seneca Rocks, West Virginia, on a day not unlike today, is etched into my mind. I can clearly recall asking him on that trip if he thought there was life on Mars. He paused for a moment and said "I ... think so". I can only hope that somewhere on Curiosity's travels across Gale crater on Mars, that something of prominence is named after Bob Wharton.
