Abstract: The authors have developed an electrostatic sampler for the reliable and autonomous collection of regolith particles on asteroids. The sampler, which employs Coulomb and dielectrophoresis forces to capture regolith particles ...

Abstract: The authors have developed an electrostatic force–based sampler to reliably and autonomously sample asteroid regolith. After applying a rectangular high voltage between parallel screen electrodes mounted at the lower end ...

Abstract: To realize reliable and autonomous sampling of regolith on the Moon and Mars, the authors have developed a unique sampling system that employs electrostatic force and mechanical vibration for the capture and transport of ...

Abstract: A magnetic sampler for future sample return missions on asteroids was developed. The sampler had a simple configuration, consisting of a solenoid coil, direct current (DC) power supply, and switching circuit, and the ...
