NASA is currently working toward the goal of putting humans on Mars in the 2030s, which is not as far away as it sounds. The space agency just last week opened the astronaut application process for the class of 2017, which indicates a certain urgency. If you're eager to see what the future holds, the Mission: Mars exhibition at the Saint Louis Science Center (5050 Oakland Avenue; 314-289-4400 or www.slsc.org) is the place to be. This interactive display is developed by the science center, Washington University and NASA and is divided into two parts. Mission Control gives you the chance to program and remotely drive a simulated Mars rover, complete with the time delay caused by the signal transit time between Earth and Mars. Mission Mars — Base lets you take on the role of an explorer on the Red Planet in the year 2076. You'll conduct scientific operations at key points using one of the science center's two rovers. Mission: Mars is open daily, and admission is free.
Price: free admission
