Abstract
The structural coefficient of restitution describes the kinetic energy dissipation upon low-velocity (~0.1 m/s) impact of a small asteroid lander, MASCOT, against a hard, ideally elastic plane surface. It is a crucial worst-case input for mission analysis for landing MACOT on a 1km asteroid in 2018. We conducted pendulum tests and describe their analysis and the results.

Comments
We intend to supplement the data processing (a rather laborious image processing and fitting to measure rotations before and after each bounce) to gain more insight into the finer physical details, which may take a couple of months
