Introduction: The distribution of boulders on an asteroid can give insight into the origin and evolution of small bodies (e.g., ). This study reviews and updates prior work by Michikami et al.,… (More)
Motivating Problem. A fascinating on-going debate concerns the asteroid sizes needed to form large craters. For example, numerical hydrocode models predict that Dast > 15-20 km and Dast > 8 km… (More)
This work presents an electrostatically tunable MEMS rotational acceleration switch and its operation as a 3-bit digital rotational accelerometer. The concept of operating electrostatically tunable… (More)
Introduction: Here we investigate the Copernican-era lunar impact flux using a new method for determining crater ages. Customarily, geological maps and crater counting methods have been used to… (More)
