Abstract SpaceIL’s lunar lander mission Beresheet was launched on February 22, 2019 and impacted its targeted landing site in Mare Serenitatis on the Moon on April 11, 2019. The spacecraft carried a package of scientific instruments including a fluxgate magnetometer and a retroreflector array for laser ranging, as well as a suite of cameras. Orbital measurements of the magnetic field from Kaguya and Lunar Prospector guided the selection of the landing site to a location west of Posidonius crater in the Serenitatis plains, where the magnitude of the modeled magnetic field reaches 8–10 ​nT ​at the surface. Data was collected by the SILMAG magnetometer from Earth orbit, lunar orbit, and during the descent maneuver, although its interpretation is hindered by the presence of a spacecraft field.

SpaceIL 的 Beresheet 着陆器的科学任务

摘要 SpaceIL 的月球着陆器任务 Beresheet 于 2019 年 2 月 22 日发射，并于 2019 年 4 月 11 日撞击了其在月球上的 Mare Serenitatis 目标着陆点。 该航天器携带了一套科学仪器，包括磁通门磁力计和用于激光测距的后向反射器阵列，以及一套相机。来自 Kaguya 和 Lunar Prospector 的磁场轨道测量引导着陆地点选择到 Serenitatis 平原 Posidonius 陨石坑以西的位置，在那里建模的磁场强度在表面达到 8-10 nT。SILMAG 磁力计从地球轨道、月球轨道和下降机动过程中收集了数据，但其解释受到航天器场的阻碍。
