"More than 30 high school, college and university teams will launch student-built rockets during the 15th annual NASA Student Launch event April 10-11 near NASA's Marshall Space Flight Center in Huntsville, Alabama. Middle school and high school teams will launch their rockets to an altitude of one mile, deploy onboard science experiments and land safely using a system of recovery parachutes. University and college teams will participate in either the Mini-Mars Ascent Vehicle (Mini-MAV) or the Maxi-Mars Ascent Vehicle (Maxi-MAV) divisions. Mini-MAV teams must use a robotic system to autonomously load a payload into their rocket, launch to half a mile and eject the payload during descent. Maxi-MAV teams, competing for a share of $50,000 in prize money, will attempt to meet more autonomy requirements before also launching to a half mile."
