Students on board "Mars Experience" bus

Students and chaperones from Virginia's Loch Lomond Elementary School robotics team watch as they seem to travel across the surface of the planet Mars, seated in the Lockheed Martin "Mars Experience" bus. The group of local students were the first to visit the bus at the Steven F. Udvar-Hazy Center in Chantilly, VA, October, 19, 2018, following a ceremony in which Lockheed Martin transferred the bus to Smithsonian's National Air and Space Museum. The bus, fitted with high-definition monitors on the windows, provides visitors an opportunity to experience the Martian surface. (National Air and Space Museum photo by Daniel Soñé)
