The majority of rovers sent to other planets have offered significant mission utility by deploying multiple-instrument packages. On the other hand, rovers are becoming increasingly large and complex with longer development times and higher engineering costs. This leads directly to greater risk-aversion that easily spirals into even higher costs and increasing risk-aversion. With so much riding on each mission, 'safe' landing sites must be selected with exceeding care and ongoing operations undertaken with ever-greater caution at every juncture -- thereby limiting exploration opportunities. Smaller rovers may offer less capability individually, yet may also provide this utility with far less cost and risk exposure, particularly if large numbers are deployed. In particular, advantages may include:
- Unit costs that are lower due to simpler designs and the economies of higher production volumes.
- More than one point of interest can be studied simultaneously.
- Instruments may be distributed among specialized vehicles that work together.
- Spare rovers can be kept in reserve during a mission, allowing consideration of higher risk operations.
- A larger rover might act as a "mother ship" to transport families of microrovers to new sites of interest.
Participation is limited to 50. There is no formal registration process or fee for students and faculty of Brown University, and we ask only that you contact us ahead of time to ensure that there will be sufficient space. Planetary researchers and robotics engineers from other institutions are invited to register online. Student sponsorship for overnight accommodation is available to student from other universities with sponsorship from the NASA Rhode Island Space Grant Consortia.
