Mission Objectives:
GRACE-FO is a successor to the GRACE mission to continue its primary goal to monitor the static and time-variable components of the Earth's gravity field. Secondly, GRACE-FO will carry a Laser Ranging Interferometer as a technology demonstrator for high accuracy inter-satellite range measurements. Also the GRACE radio occulation measurements will be continued.
