Scientific paper

OASIS (Onboard Autonomous Science Investigation System) is a research project at NASA's Jet Propulsion Laboratory (JPL) working to increase the science return from missions. Given specified bandwidth constraints for communicating data from a spacecraft back to Earth, OASIS can use predetermined criteria from scientists to prioritize the information sent home. This past year, OASIS has successfully demonstrated a new, autonomous, end-of-day science targeting and data acquisition capability on the FIDO research rover in the JPL Mars Yard. By analyzing an end-of-day panoramic image taken by their FIDO navcams, OASIS autonomously finds rocks in an image, determines rock properties and then identifies rocks for further data acquisition by an instrument such as a laser induced breakdown spectrometer (LIBS). OASIS then instructs the rover to point to the five rocks it has selected on which to obtain data. As FIDO does not have a LIBS instrument onboard, OASIS has the rover take an additional image with the higher-resolution FIDO pancams and indicate the point on each rock where the LIBS would have aimed. The end-of-day science capability can greatly increase the science return over blind sampling and can provide valuable information for planning activities for the following day. OASIS continues to make progress in its goal to develop technologies that will help missions increase their science return by evaluating, and autonomously acting upon, science data gathered by in-situ spacecraft, such as planetary landers and rovers.
