Moonraker has been proposed as ESA M-class mission designed orbit Saturn perform multiple...
Residual charges of individual microparticles forming dense clouds were measured in a RF discharge afterglow. Experiments performed under microgravity conditions on board the International Space Station, which ensured particle levitation inside gas volume after plasma switch-off. The distribution residual as well spatial charged particles across cloud analyzed by applying low-frequency voltage to electrodes and measuring amplitudes resulting oscillations. Upon “free decharging” conditions,...
BOOST (BOOst Symmetry Test) is a proposed satellite mission to search for violations of Lorentz invariance by comparing two optical frequency references. One based on long-term stable resonator, and the other hyperfine transition in molecular iodine. This will allow us determine several parameters standard model extension electron sector up 2 orders magnitude better than with current best experiments. Here, we give an overview mission, science case, payload.
