Mars Sample Return Campaign Concept Review

Progress to Date• NASA conducted an Acquisition Strategy Meeting (ASM) in July 2019 and

made Center roles/responsibilities assignments• ESA obtained approval for MSR at Nov 2019 Ministerial Council• Campaign Reference Architecture Stakeholders Peer Review (CRASPR) in

January 2020 brought all implementing organizations together• MSR was included in President’s FY2021 budget request and has been

called out in FY21 House CJS report language• ESA selected Earth Return Orbiter (ERO) contractor in March 2020• ESA selected Sample Fetch Rover (SFR) contractor in June 2020

Campaign Timeline Overview

• Sample Retrieval Lander (SRL) avoids winter and global dust storm season, enabling all-solar SRL/SFR

• SRL EDL occurs in a favorable season, maximizing landed mass• ERO can provide all relay services needed for MSR (SRL, SFR, M2020, Mars Ascent

Vehicle (MAV))• SRL and ERO fit on available launch vehicles and trajectories are feasible

SRL Comparison to Mars 2020/Perseverance• No science payloads• Precision landing (from M2020) simplifies landing site requirements• Stationary (SFR is contributed)• Simpler operations activities (more similar to InSight)

Capture, Containment and Return System (CCRS) Overview • CCRS is the payload on the

ESA provided ERO• Key functionalities:

• Rendezvous and capture Orbiting Sample (OS)

• In-flight robotic assembly of Earth Entry System (EES), including Break-the-Chain (BTC) and Containment Assurance activities

• EES delivery to Utah Test and Training Range (UTTR) while meeting biosignaturepreservation potential (BPP) requirements (w/ ESA/ERO)

• CCRS elements and their functions:• Capture and Containment

Module (CCM) • Earth Return Module (ERM)
