An ultra-low altitude lunar orbiter presents enhanced science returns with high-resolution data at the meter/cm scale. The orbiter would mitigate perturbations due to lunar mascons and navigate topography to maintain a near circular polar low altitude orbit. Potential instrumentation includes imaging, fields and particles, and thermal mappers.
