Phrase: GRACE Follow-On | Statement: [GRACE mission, successorMissionFullName, GRACE Follow-On]

Target entity: GRACE Follow-On
Context triple: [GRACE mission, successorMissionFullName, GRACE Follow-On]

• A. GRACE mission
  The GRACE mission is a joint NASA–German Aerospace Center satellite project that precisely measures Earth's gravity field over time to study changes in ice sheets, sea level, groundwater, and other aspects of the global water cycle.
• B. Aqua satellite
  Aqua is a NASA Earth observation satellite focused on studying the planet’s water cycle, including oceans, atmosphere, and ice.
• C. Deep Space Climate Observatory
  The Deep Space Climate Observatory (DSCOVR) is a NOAA and NASA satellite positioned at the Sun–Earth L1 Lagrange point that continuously monitors solar wind conditions and provides real-time space weather and Earth observation data.
• D. Tropical Rainfall Measuring Mission
  The Tropical Rainfall Measuring Mission (TRMM) was a joint NASA–JAXA satellite mission launched in 1997 to measure tropical and subtropical rainfall and improve understanding of the global water and energy cycle.
• E. PRISMA Earth observation mission
  The PRISMA Earth observation mission is an Italian Space Agency satellite program that uses hyperspectral imaging to monitor Earth’s environment, land use, and natural resources.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Generate a one-sentence description of the target entity. 
You are given a context triple in the form (subject, predicate, object), where the object is the target entity. 
# Instructions
