About OASIS
Rover traverse distances are increasing at a faster rate
than downlink capacity is increasing. As this trend continues, the
quantity of data that can be returned to Earth per meter traversed is
reduced. The capacity of the rover to collect data, however, remains
high. This circumstance leads to an opportunity to increase mission
science return by carefully selecting the data with the highest science
interest for downlink. We have developed an onboard science analysis
technology for increasing science return from missions. Our technology
evaluates the geologic data gathered by the rover. This analysis is
used to prioritize the data for transmission, so that the data with the
highest science value is transmitted to Earth. In addition, the onboard
analysis results are used to identify science opportunities. A planning
and scheduling component of the system enables the rover to take
advantage of the identified science opportunity.
What is traverse science?
- Scientifically characterizing the terrain during long
rover traverses.

- Collecting science information while traveling from
point A to point B.

- Developing methods for prioritizing a set of
rocks/images according to their scientific importance.
- Responding to science opportunities identified during
the traverse.
- Science during rover traverse
- science information gained for
surface areas for which no information would otherwise be available
- Data prioritization for downlink
Traverse Science Scenarios
 |
- Prioritize images collected during
traverse for downlink
- Collect inexpensive extra data of
potentially interesting objects
- Slightly adjust path to get better view
of a very interesting object
- Approach and take contact measurement of
an extremely interesting object
|
Approach
Onboard traverse science data analysis system that will
increase the total science return of MSL and other missions
- Image Segmentation and feature
extraction: 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 contact
measurement
