Joanna Clark became a full\-time member of the Mars group at the NASA Johnson Space Center through the JETS II Contract, working under [Jacobs Solutions Inc](/wiki/Jacobs_Solutions "Jacobs Solutions"). It is within this group that one of their primary science objectives is to assess the habitability of ancient and modern martian environments by using the [Curiosity rover](/wiki/Curiosity_%28rover%29 "Curiosity (rover)") through a series of instruments and technologies that include: [SAM](/wiki/Sample_Analysis_at_Mars "Sample Analysis at Mars"), [CheMin](/wiki/CheMin "CheMin"), [APXS](/wiki/Alpha_particle_X-ray_spectrometer "Alpha particle X-ray spectrometer"), [ChemCam](/wiki/Chemistry_and_Camera_complex "Chemistry and Camera complex"), [DAN](/wiki/Dynamic_Albedo_of_Neutrons "Dynamic Albedo of Neutrons"), [REMS](/wiki/Rover_Environmental_Monitoring_Station "Rover Environmental Monitoring Station"), [RAD](/wiki/Radiation_assessment_detector "Radiation assessment detector"), [MastCam](/wiki/Mastcam-Z "Mastcam-Z") \& [MAHLI](/wiki/Mars_Hand_Lens_Imager "Mars Hand Lens Imager").
