In 1997, Lee initiated the Haughton-Mars Project (HMP), an international multidisciplinary field research project centered on science and exploration studies at the Haughton impact crater and surrounding terrain on Devon Island, Arctic Canada, viewed as an analog site for the Moon and Mars. Lee has led over 18 HMP field expeditions to date, including the "Northwest Passage Drive Expedition" in April 2009 and May 2010, and continues to serve as the HMP's Director in support of research for NASA and the Canadian Space Agency.
