MSL Project Update

Mars Science Lab (MSL) Project activities over the last 3-4 months focused on: a) Payload accommodation; b) Flight system architecture definitization; c) Program architecture support. Baseline project concept is to develop and fly two identical vehicles with launches in 2009 and 2011: a) Significant programmatic uncertainty remains due to NASA strategic issues (Shuttle Return to flight, Hubble servicing, CEV, etc.); b) Final "decisions" on future program not likely for 3-4 months; c) To maintain viability for a 2009 launch, the project must rapidly move into implementation mode despite this uncertainty. Near term activities: a) Converge baseline flight system architecture & instrument accommodation - June; b) Instrument accomodation reviews (IARs) are completed for DAN, MSSS instruments; c) Develop project-wide implementation plan & integrated schedule - June; d) Conduct grassroots cost exercise - July/August; e) Hold Preliminary Mission System Review - September.
