月球背面重力场是通过中继子卫星从月球与工程探测器（SELENE）的跟踪数据中得到改进的。新的重力场模型显示，与近侧的正异常环不同，远侧具有负异常环。一些盆地具有较大的中心重力高点，这可能是由于地幔的超均衡动态隆起所致。其他具有高点的盆地与海相充填有关，这意味着发达的断层促进了玄武岩的喷发。远侧的盆地地形和地幔隆起由刚性岩石圈支撑，而近侧的盆地因喷发而发生了大幅变形。近侧和远侧的不同补偿方式表明，近侧岩石圈的再加热和弱化比之前认为的更为广泛。
The farside gravity field of the Moon is improved from the tracking data of the Selenological and Engineering Explorer (SELENE) via a relay subsatellite. The new gravity field model reveals that the farside has negative anomaly rings unlike positive anomalies on the nearside. Several basins have large central gravity highs, likely due to super-isostatic, dynamic uplift of the mantle. Other basins with highs are associated with mare fill, implying basalt eruption facilitated by developed faults. Basin topography and mantle uplift on the farside are supported by a rigid lithosphere, whereas basins on the nearside deformed substantially with eruption. Variable styles of compensation on the near- and farsides suggest that reheating and weakening of the lithosphere on the nearside was more extensive than previously considered.
