Mars Program Update From “Follow the Water” to “Seeking Signs of Life”
4
A public forum at the National Air and Space Museum (NASM) on January 13, 2011, to review the evidence of water on Mars, current Mars missions and future Mars activities.
Three panels were moderated by Dr. John Grant (NASM Chair, Center of Earth and Planetary Studies):
1) Follow the Water: What Have We Found? 2) How Do We Do It? Status of Current Missions 3) Seeking Signs of Life: What Will the Future Bring?
Planetary Science Division panelists included Doug McCuistion, Michael Meyer and Mary Voytek. Other panel members included Jack Mustard (Brown University), Steve Squyers (Cornell University), Marcello Coradini (ESA) and Jennifer Eigenbrode (GSFC).
Standing room attendance at the event was over 200, including students from Stuart-Hopson Middle School and the Whittier Education Campus STEM School. The event was carried live on NASA TV and on Livestream. As of Jan. 24 Livestream reported over 98,000 viewer minutes, and 4425 viewers on http://youtube.com/nasatv.
The Mars Update Program was carried live and is archived at http://www.livestream.com /mars

Mars Exploration Program Missions
• Mars Odyssey – orbiter and its subsystems and the THEMIS, HEND & NS continue to perform.
• Mars Reconnaissance Orbiter – orbiter and its subsystems are performing nominally
• Mars Express – spacecraft operations are nominal—extended mission through 2012.
• Mars Exploration Rover Project – Spirit – Spirit remains silent, no communication has been received since Sol 2210
(March 22, 2010). It is likely that Spirit has experienced a low-power fault and has turned off all sub-systems. Probability of recovery is diminishing.
– Opportunity –Opportunity is headed toward Endeavor Crater. Total odometry 26.7km (about 16.6 miles)
• Mars Science Laboratory – Rover fully assembled and environmental test begins with vibe on 14 February.
• Mars Atmosphere and Volatiles Evolution (MAVEN) – Passed KDP-C and officially in Implementation Phase (Phase C)
• 2016 TGO – Passed ESA’s System-PDR in December 2010; KDP-A for NASA portion scheduled for March 30th.
• 2018 Dual Rovers – Design concept trade studies still underway

The MSL-Curiosity Rover Mission
Rover Width: 2.8 m Height of Deck: 1.1 m Ground Clearance: 0.66 m Height of Mast: 2.2 m
DAN
REMS
ChemCam Mastcam
RAD
MAHLI APXS Brush Drill / Sieves Scoop
MARDI
Objectives:
•Assess the biological potential of the site by investigating any organic and inorganic compounds and the processes that might preserve them
•Characterize geology and geochemistry, including chemical, mineralogical, and isotopic composition, and geological processes
•Investigate the role of water, atmospheric evolution, and modern weather/climate
•Characterize the spectrum of surface radiation
Curiosity’s primary scientific goal is to explore and quantitatively assess a local region on Mars’
surface as a potential habitat for life, past or present

MSL Development Progress • Overall status:
– On track for shipment of spacecraft to KSC in June, and on-time launch in November/December launch window. Current technical issues in-family for this phase of development.
• SA/SPaH Development – Organic contamination of drill bit identified during manufacturing process – Drill force sensor anomalous performance
• SAM – Series of Wide Range Pump problems associated with bearing design and materials resolved – SAM now fully integrated into rover
• Rover Battery – Contamination of percussive weld bead on header/picket assembly – Pursuing rebuilding and reworking header assemblies for flight/flight spares
• Budget – Unacceptably low project reserves going in to FY 2011 – Agency PMC approved augmentation in Dec ‘10 to restore budget reserve posture to ensure successful
development/test completion; reserves partially held by HQ
• Lessons Learned – Numerous IG and GAO reviews/audits underway – Internal NASA Lessons Learned activity jointly with OCE will start up soon
9
Curiosity Milestones
• Environmental test sequence begins: 14 Feb, 2011
• Call for Participating Scientist proposals – ~18 expected selections – 4 ½ years duration – Proposals due March 22, 2011
• Launch Site Selection:
– Last workshop in May; early summer down-select
• Launch Window opens: Nov. 25, 2011
• Landing on Mars: Aug. 2012 9

Candidate Landing Sites
Eberswalde Crater (24°S, 327°E, -1.5 km) contains a clay-bearing delta formed when an ancient river deposited sediment, possibly into a lake.
Gale Crater (4.5°S, 137°E, -4.5 km) contains a 5-km sequence of layers that vary from clay-rich materials near the bottom to sulfates at higher elevation.
Mawrth Vallis (24°N, 341°E, -2.2 km) exposes layers within Mars’ surface with differing mineralogy, including at least two kinds of clays.
Holden Crater (26°S, 325°E, -1.9 km) has alluvial fans, flood deposits, possible lake beds, and clay-rich sediment.

Joint Mars Exploration Program A New Kind of SMD International Partnership
This is a partnership between programs – Historically, partnership with ESA is on a single mission basis – Quid pro quo is balanced across multiple missions, not within a single
mission – Leadership of missions is negotiated and alternated – Partnership leverages resources, enabling increased mission content and
launch frequency over a period of years – Sharing risk and responsibility of technology developments (within ITAR) – Each mission’s risks and successes affect future missions, regardless of
who is the “mission lead” • Intertwined critical paths • Technology and schedule risk
Overall risk posture increases when partnering at program level
–but– The benefits outweigh the risks
17
NASA-ESA Joint Mars Program Management Structure Program Initiation and Mission Formulation
• Management structure established – Joint Mars Executive Board—meets regularly – Joint Engineering Working Group(s) for future mission concepts – Joint Mars Architecture Review Team (jMART) established
• Bi-Lateral (Dr. Southwood and Dr. Weiler)—meets regularly
• 2016 mission project office established within Mars Program Office at JPL
– ESA orbiter mission under ExoMars Program Office • Overall governance, documentation, review and approval processes, etc.,
maturing – Presented to NASA Agency Program Management Council in Oct ‘10
• MSR working group established in April 2010

– Identify possible locales for future surface/subsurface exploration
=> These goals can be summarized as: Detection, Characterization, Localization
2016 ExoMars/Trace Gas Orbiter (TGO) Science Objectives
19
• Detect and survey trace gases and their isotopologues in the Mars atmosphere in order to understand the nature of their subsurface/surface sources: Biochemical and geochemical?
– Including but not limited to H2O, HO2, H2O2, NO2, N2O, CH4, C2H2, C2H4, C2H6, H2CO, HCN, H2S, OCS, SO2, HCl, CO, O3
– Confirm their presence and variability over all Mars seasons – not just methane!
• Characterize the processes by which methane, other trace gases, and aerosols interact and are possibly removed from the atmosphere − H2O, CO2, ice and dust aerosol

2018 Dual Rovers Mission
Touchdown Through Initial Deployments Stand-Up and Egress
Sky Crane Maneuver
Cruise stage & aeroshell separation • Mars 2018 is 2nd mission of NASA-ESA Joint Mars Exploration Program
– Delivers to Mars surface the ESA ExoMars Rover and a proposed NASA Sample & Caching Rover
– NASA to provide launch/cruise/EDL for both rovers • Current conceptual design would maximize use of MSL-heritage Launch, Cruise, and EDL systems
• Mars 2018 Project is currently in Pre-Phase A – Working towards Mission Concept Review & issuance of
Formulation Authorization Document, in conjunction with Key Decision Point A (KDP-A) in late 2011/early 2012 • Note: ESA Rover has been under development for > 4 years. The
ESA ExoMars Project considers the rover maturity to be at PDR (Phase B->C transition) level
• Key Milestones – Apr. ‘11: NASA/ESA Interface Requirements Doc., Version 1 – Nov. ’11: Mission Concept Review (leads to KDP-A Jan. ’12) – KDP-A: Jan. ’12; KDP-B: Apr. ’13; KDP-C: Sep. ’14
