Local spectrophotometric properties of pyroclastic deposits at the Lavoisier lunar crater
Besse, S.; Josset, J. -L.; Haruyama, J. +5 more
We present a study of the Lavoisier lunar crater combining photometric data from the AMIE camera (SMART-1 mission) and hyperspectral data from the Moon Mineralogy Mapper M3 (Chandrayaan-1 mission), with a special emphasis on the pyroclastic deposits considered to be present on the crater floor. The photometric parameters are in agreemen…
Laser ablation in a running hall effect thruster for space propulsion
Balika, L.; Focsa, C.; Gurlui, S. +4 more
Hall Effect Thrusters (HETs) are promising electric propulsion devices for the station-keeping of geostationary satellites (more than 120 in orbit to date). Moreover, they can offer a cost-effective solution for interplanetary journey, as proved by the recent ESA SMART-1 mission to the Moon. The main limiting factor of the HETs lifetime is the ero…
