Opportunities to collect test pieces from various kind of bodies in space is increasing. In this study we obtained data required for design of a device which collects samples by shooting a small projectile onto the targeted bodies and concentrating ejected fragments through a funnel-shaped horn. We made a series of studies including experiments to investigate production of fragments at impact and motion of fragments reflecting inside the horn, capturing tests both in 1 G environment on the ground and under reduced gravity using an airplane. These investigations show that more than 40% of the ejecta from brick-like bodies can be caputured by this device.
