Doug Ming is a Co-Investigator on the CheMin and SAM instruments. During daily tactical operations, he is the Science Operations Working Group (SOWG) Chair and leads the science team through all tactical science meetings and directs the team to a consensus on daily science activities.

Dick Morris is a Co-Investigator on the CheMin and SAM instruments. He is a Payload Downlink Lead (PDL) for CheMin, so on a daily basis, he downlinks data from the CheMin instrument and assesses instrument health.

Liz Rampe is a Co-Investigator on the CheMin instrument and the Deputy Principle Investigator of CheMin. She is the CheMin Operations Lead, so she is in charge of training new CheMin operations team members and of keeping all current CheMin operations team members current on their training. She is also a PUL and PDL for CheMin.

Doug Archer is a collaborator on the MSL science team and a Payload Downlink Lead (PDL) for the Sample Analysis at Mars (SAM) instrument. As a science team member, he is a Science Operations Working Group (SOWG) Chair, leading the science team through tactical operations to design and deliver a plan that will be executed by the rover on Mars. As a SAM PDL, he is responsible for downlinking data from the instrument, checking instrument health and safety, and analyzing science data.

Michael Thorpe is a member of the Mars Science Laboratory team and works directly with the CheMin instrument. Mike participates in CheMin Operations, training as both a PUL and PDL, and data analysis for the CheMin team.

Valerie Tu is a collaborator on the Chemistry and Mineralogy (CheMin) X-ray diffraction instrument team, on-board the Mars Science Laboratory (MSL) rover, Curiosity. Valerie performs mission operations for CheMin as both an uplink and downlink lead, and helps interpret CheMin data, and the mineralogy of martian sediments.

Joanna Clark is a collaborator on the Mars Science Laboratory (MSL) Curiosity rover science and operations team. Specifically, Joanna works with the Sample Analysis at Mars (SAM) instrument, where she performs laboratory analog experiments to understand and interpret the data coming from the SAM instrument on Mars. She is also a payload uplink lead (PUL) on the SAM operations team, which involves sending commands to the SAM instrument on Curiosity to tell it which experiments to do.

Brad Sutter is a collaborator on MSL’s Sample Analysis at Mars instrument team whose role is analysis and interpretation of SAM-evolved gas analyzer data. Brad also serves as a Geo Science Team Lead (GeoSTL) whose role is to lead MSL’s Geology Mineralogy theme group in deciding the next sol’s planning of instrument analysis and imaging as well as establish which analyses and imaging should be considered in the long term.

Tanya Peretyazhko is a collaborator on the Chemistry and Mineralogy (CheMin) X-ray diffraction instrument team, on-board the Mars Science Laboratory (MSL) rover, Curiosity. Tanya helps with data interpretation by performing experimental and modeling studies.

Jeff Berger is a collaborator on the MSL Science Team. During rover operations, he is a Payload Uplink/Downlink Lead (PUDL) for the APXS instrument. He is also a Strategic Planner (SP) for the APXS team, working to ensure the highest-quality science return from APXS Operations.

Candice Bedford is a collaborator on the CheMin and ChemCam instrument teams. Candice combines the mineralogical and geochemical datasets from these instruments to investigate the effects of mineral sorting, chemical weathering, alteration and source rock characteristics on the rock record preserved in Gale crater, Mars.
