thought about,” Bolden stated in an interview, referring to the outcome of the EDC. “It may be totally different and it may even be affordable, which is most important. So, it is my expectation that we will find something that we didn’t think about.” The design challenge is divided into three levels. For the first two groups – children in kindergarten through 4th grade, and 5th through 8th grades – their teachers will lead them through studying the effects of radiation on human space travelers and analyzing materials that can simulate space radiation shielding for Orion. After participating in these activities, the students will recommend materials that best block harmful radiation. At the high school level, grades 9 through 12, students will design the shielding to protect a sensor inside Orion from space radiation. “There will be five teams chosen to test their designs in a virtual radiation simulator,” said Leland Melvin, a Space Shuttle astronaut and NASA’s associate administrator for education. “All five teams that are chosen will go down to Kennedy Space Center for the launch of EFT-1 and there will be a final down-select of the winning design that will possibly be flown on EFT-1.” “We’re banking on this design because one of you, or one of our astronauts, will be flying to Mars,” he said. “We will be using space-certified radiation sensors sitting behind your radiation shield to see how effective it is working at blocking radiation.” An artist concept (above) shows Orion as it will appear in space for the Exploration Flight Test-1 attached to a Delta IV stage, (Left) NASA’s Orion Exploration Flight Test-1 (EFT-1) insignia.

Lockheed Martin is NASA’s prime contractor for the Orion MPCV and is building the capsule that will fly on EFT-1. “Every journey starts with a single step and the Orion’s Exploration Flight Test-1 is a significant first step toward deep space human exploration,” she said. “This mission will lay the foundation for future Orion flights and will take astronauts past the moon and on to asteroids and Mars.” All the students who take part in the design challenge will join the mission as “honorary crew members” by having their names flown aboard the Orion. The winning team’s status will be more than honorary — their radiation shield design may someday protect Orion’s real crew members. “You’re about to embark on an amazing journey,” Hewson said. “The skills you’ll learn from this challenge — problem solving, critical thinking and systems engineering — are the very same skills that our engineers apply to our most challenging problems every day.” “You are taking on a mission that is hugely important — keeping our astronauts safe during a journey through deep space.” NASA Administrator Charles Bolden and Lockheed Martin CEO Marillyn Hewson sign an For details on how students can enter agreement enabling NASA’s Exploration Design Challenge for students.
