## Mars Architecture Tiger Team Report

- The OMB requested an architecture from NASA for the Mars Exploration Program for the next decade
- NASA chartered an assessment group to develop this architecture and provide an evaluation of the Mars Program relative to the SMD budget proposal submitted in the President’s 5-year budget plan
- Group consisted of 19 members of Mars science and engineering community, including the Chairs of MEPAG, the MEPAG Next Decade (ND), Mars Science Orbiter (MSO) and Mars Science Strategy (MSS) Science Analysis Groups, the MSO Science Definition Team, and CAPTEM
- Group met in Washington D.C. on Feb. 14-15, 2008

## Mars Architecture Tiger Team Report

- Assessment of the Mars Exploration Program architectures based on the President’s FY09 Budget release for 2009-2013 and SMD planning estimates for 2014-2020
- Incorporation of the recommendations from the NRC Decadal Survey and the ND-SAG, MSS-SAG, and CAPTEM reports
- Options for 2016 from MSS-SAG
- Science priorities for collected samples from ND-SAG
- The SMD stated desire for an MSR landed element no later than 2020 with a U.S. contribution to MSR of no more than $3.5B
- Assessment of possible architectures relative to the stated science goals of the Mars Exploration Program
- The assumption of significant international contribution

## Mars Architecture Tiger Team Report

- A science-driven architecture based on the SMD plan and the  recommendations of the NRC Decadal Survey, the MEPAG Goals committees, and the MEPAG Science Analysis Groups over the past 5 years
- Budget-driven architectures based on the recently released President’s 5-year budget (FY09-FY13).  For the FY14-FY20 period the group considered 2 options:
- The current SMD Planning budget with a significant funding increase in FY17 through FY20
- A flat funding profile that was based on the average of FY10-FY12 for FY14 through FY20

## Architecture Assessment Summary

*Key points*
*Given adequate funding the SMD plan can maintain the Mars Program and achieve its science goals*
*With the SMD Budget plan*
*MSR options have only Scout mission between MSL and MSR*
*≥**11 year period between NASA Mars landings (2009 to ≥2020)*
*A 4 year gap exists between flight elements of MSR*
*Only 5 months of surface operations for MSR rover launched in 2022*

***CONCEPT***

## Conclusions

*However, the SMD planning budget, which includes the President’s 5-year decreasing budget, does not support this architecture even with the planned rapid increase in funding beginning in FY17 *
*Estimated cost of this balanced architecture is ~$6B, including an estimated cost of an MSR mission with modest scientific goals of ~$4-5B; however total SMD funding for new missions through FY20 is ~$4B*
*Phasing of SMD funding does not ramp up in time for a mission in 2016 nor for MSR launches in 2018 and 2020*
*The MSR mission would require a substantial international contribution above the $3.5B U.S. contribution currently planned*

***Conclusions***

## Conclusions

*An MSR program with Scout in 2013 followed by the launch of the MSR mission elements in 2018 and 2022; or*
*An architecture dedicated to the earliest launch of MSR, with no missions following MSL and the launch of the MSR mission elements in 2016 and 2020*
*If the projected reinstatement of the funding for Mars exploration to levels of $500-900M per year does not occur sometime after 2013, then MSR will not happen*
*Projected funding levels in FY11-FY16 are ~$390M per year*
*Level funding could support medium-sized missions launched every other opportunity (not flagships)*

***Conclusions***

## Conclusions

*Lack of progress toward the four goals of planetary science set out by the NRC Decadal Survey *
*Loss of scientific balance*
*Loss of technical and scientific expertise as a result of the >11 year hiatus between landed missions of MSL and MSR*

***Conclusions***

## Conclusions

*In all planning exercises the Mars Program should remember that:*
*Major technology development is required starting at least 5 years prior to the MSR development*
*The existing assets at Mars have great capabilities that can be utilized to support future missions, including site characterization and certification, atmospheric characterization, and relay*
