Low-cost, light-weight Mars landing system

Based on the Mars 2001 lander, a design for a low cost Mars landing system with a 50-150 kg payload class capability is presented. Discussion includes a history of the design considerations to achieve high payload masses, including technology insertion, as well as discussion of design optimization. The enhancements and changes based on lessons learned from MPL are presented, as well as additional options for addressing issues raised during the failure review investigations. Also addressed is the adaptability of the design to different payload configurations and launch opportunities. Operational approaches to accommodate large number of payloads, onboard resource allocations and budgeting issues, timeline and planning constraints imposed by round trip light time, communication coverage, and shift planning are discussed. Parameters unique to landed Mars missions that can be traded against one another to achieve specific mission objectives are also discussed along with observations on their impact to mission design and planning.
