| About OASIS
Rover traverse distances are increasing at a faster ratethan downlink capacity is increasing. As this trend continues, thequantity of data that can be returned to Earth per meter traversed isreduced. The capacity of the rover to collect data, however, remainshigh. This circumstance leads to an opportunity to increase missionscience return by carefully selecting the data with the highest scienceinterest for downlink. We have developed an onboard science analysistechnology for increasing science return from missions. Our technologyevaluates the geologic data gathered by the rover. This analysis isused to prioritize the data for transmission, so that the data with thehighest science value is transmitted to Earth. In addition, the onboardanalysis results are used to identify science opportunities. A planningand scheduling component of the system enables the rover to takeadvantage of the identified science opportunity.
What is traverse science?
- Scientifically characterizing the terrain during longrover traverses.
- Collecting science information while traveling frompoint A to point B.
- Developing methods for prioritizing a set ofrocks/images according to their scientific importance.
- Responding to science opportunities identified duringthe traverse.
Benefits
- Science during rover traverse
- science information gained forsurface areas for which no information would otherwise be available
Data prioritization for downlink
form of data compression
Traverse Science Scenarios
 |
- Prioritize images collected duringtraverse for downlink
- Collect inexpensive extra data ofpotentially interesting objects
- Slightly adjust path to get better viewof a very interesting object
- Approach and take contact measurement ofan extremely interesting object
|
Approach
Onboard traverse science data analysis system that willincrease the total science return of MSL and other missions
- Image Segmentation and featureextraction: rock detection, soil and atmosphere
- Science analysis: data prioritization, science alert,data summarization
- Planning and scheduling: responses to data analysis –collect new data, stop and call home, adjust path and contactmeasurement
