任务简介
GRACE-C（重力恢复与气候实验-延续）是原GRACE和GRACE-FO任务的后续任务，通过提供地球重力场的逐月变化来追踪全球范围内的水运动与地表质量变化，监测冰盖、冰川、地下水储量、土壤湿度和海平面的变化。 GRACE-C由两颗相同的卫星组成，在500公里高度、倾角89度的轨道上飞行，彼此相距约200公里。每颗卫星尺寸约为3 x 2 x 1米，重约600公斤。 此次发射还将通过Exolaunch搭载拼车小卫星。
原文
GRACE-C (Gravity Recovery and Climate Experiment-Continuity) is a successor to the original GRACE and GRACE-FO missions, providing month-to-month changes of Earth's gravity field to track water movement and surface mass changes across the planet, monitoring variations in ice sheets, glaciers, underground water storage, soil moisture, and sea levels. GRACE-C consists of two identical satellites flying around 200 km apart at an orbit altitude of 500 km with an inclination of 89 degrees. Each satellite will measure approximately 3 x 2 x 1 meters and weigh around 600 kg. This launch will also carry ride-sharing small satellites via Exolaunch.
