Mars Sample Return Lander Mission Concepts

This paper will provide an overview of current concepts and options for the architecture and design of a Mars Sample Return Lander (called Sample Return Lander, SRL). Key mission objectives and the overall baseline mission design will be described, including the mission's constraints and a notional timeline from launch to entry, through surface operations, to delivery of the samples to Mars orbit. The overall lander vehicle concepts will be described, including current options being evaluated. Key lander element options will be discussed, including the Mars Ascent Vehicle (MAV), Sample Fetch Rover (SFR), Orbiting Sample container (OS), and tube transfer robotics systems. Specific challenges and approaches for addressing those challenges will be discussed, including backward planetary protection.
