Status: Future, Implementation
Mission Category: Earth Systematic Missions, Decadal Survey 2007, Tier 3, Other
Launch Date: April 14, 2018
Launch Location: Vandenberg Air Force Base

The objective of the Gravity Recovery and Climate Experiment Follow On (GRACE-FO) mission is provide high-temporal-resolution gravity field measurements for the purpose of tracking large-scale water movement. GRACE-FO is the follow-on mission to GRACE, launched in 2002.

Key Gravity Recovery and Climate Experiment Follow On Facts

Mission/Portal Page:
Launch Vehicle: SpaceX Falcon 9
Altitude:Distance from sea level. 490km
Inclination: 89°
Origination: NASA, German Research Centre for Geosciences (GFZ)
Instruments: GRACE-FO uses a Microwave Instrument (MWI), which is a microwave ranging system based on global positioning system (GPS) technology, and a very sensitive accelerometer (an instrument that measures the forces on the satellites besides gravity).
GRACE-FO will also have an experimental instrument called the Laser Ranging Interferometer (LRI).
