mISSion imaginaTIon, a joint venture between NASA and Texas Instruments, challenges students to take the knowledge gathered from missions aboard the International Space Station and adapt proven systems and process for a future #JourneytoMars. For the second activity, students are challenged to design a waste management system. To help them along the way, Kristen Fortson, International Space Station program Stowage and Disposal lead at the Johnson Space Center explains the different types of waste that astronauts accumulate, how waste is managed and disposed of on the International Space Station, and what NASA is doing to help prepare for future missions. Are you ready to put science, technology, engineering and mathematics to work, and take the next big leap? www.missionimagination.com
