After NASA shut down the Space Shuttle Program, the remaining shuttles and replicas were divided among several cities, as museum displays. Over the past few weeks, two shuttles that never flew to space were transported by barge to their new homes. The Enterprise was sailed up the Hudson River to its new position aboard the U.S.S. Intrepid, part of the Intrepid Sea, Air and Space Museum, and the shuttle replica named Explorer sailed from Florida to Houston, Texas, where it will be displayed at the Johnson Space Center. Images of these two journeys by sea are collected below.
