Abstract:
The Mars Survey Laboratory (MSL), scheduled for launch in fall of 2009, is designed to determine if Mars ever possessed an environment capable of supporting microbial life. The landed mass of the MSL rover vehicle is 600 kg, approximately double any previous payload landed on Mars. The ballistic coefficient for the MSL aeroshelVpayload (2750 kg) combination is sufficiently high as to require the largest parachute and highest Mach number at deployment of any Mars mission. As for all previous Mars missions, MSL will use a disk-gap-band (DGB) parachute. This parachute will have a nominal diameter of 19.7 m and may be deployed up to M = 2.2 and q = 500 Pa.
