GRACE II : Gravity Recovery and Climate Experiment

GRACE intro image

GRACE II will continue to provide detailed measurements of Earth's gravity field which will lead to discoveries about gravity and Earth's natural systems.

GRACE, twin satellites launched in March 2002, are making detailed measurements of Earth's gravity field which will lead to discoveries about gravity and Earth's natural systems. These discoveries could have far-reaching benefits to society and the world's population.
