The symposium on exploration discussed key questions for humans who embark on journeys of exploration where there is remarkable potential for discovery. When it comes to exploring earth, air, ocean and space, MIT’s contributions have shaped the 20th century. Great inventors and explorers such as MIT’s own Doolittle, Draper, and Edgerton contributed breakthrough technologies and instrumentation along with personal exploration and piloting feats. These inventors, engineers, scientists, and artists literally put us on the Moon and let us ‘see the unseen’.
