In June 2010, Cameron met with officials of the Environmental Protection Agency to discuss possible solutions to the Deepwater Horizon oil spill. It was reported that he offered his assistance to help stop the oil well from leaking. He is a member of the NASA Advisory Council and he worked with the space agency to build cameras for the Curiosity rover sent for Mars. However, NASA launched the rover without Cameron's technology due to a lack of time during testing. He has expressed interest in a project about Mars, stating "I've been very interested in the Humans to Mars movement [...] and I've done a tremendous amount of personal research for a novel, a miniseries, and a 3D film". Cameron is a member of the Mars Society, a non-profit organization lobbying for the colonization of Mars. Cameron endorsed Democratic candidate Hillary Clinton for the 2016 United States presidential election.
