Crowds of visitors line up for the NASA Orion Journey to Mars ride at the Houston Texas NFL Live Super Bowl LI event on Discovery Green Jan. 27, 2017. With people safely seated and virtual googles in place the ride pulls the Orion capsule up 90 feet then drops them suddenly to the bottom providing a physical experience as well as a visual one while experiencing the trip to Mars and back. The virtual reality trip is a popular no cost feature as part of NASA’s Future Flight area which also houses many other NASA space exploration and science exhibits. NASA PHOTOGRAPHER: Robert Markowitz
