Explorers: Earth, Air & Space

Throughout its history, the U.S. military has explored — first over the earth via land and sea, then into the skies, and finally into space. This legacy of exploration can be seen here at Arlington National Cemetery, the final resting place of many people who expanded our understanding of the earth, air and space. As you learn about their journeys, consider which expedition objectives may have been most important to their sponsors at the time, and how the expedition outcomes have influenced your understanding of the world today.
