abstract = "{At the time that the 2017{\textendash}2027 Decadal Survey for Earth
Science and Applications from Space was released, there was a
strong emphasis on reducing the possibility of a substantial gap
between the GRACE Follow-On mission and a successor mission.
This has led to the subsequent rapid development of a successor
mission in partnership between NASA and DLR, GRACE-Continuity
(GRACE-C), expected to launch in 2028, to continue the
timeseries of Earth system mass change established by GRACE and
GRACE-FO. In parallel, ESA continues development of a pair of
satellites called Next Generation Gravity Mission (NGGM),
targeted for an inclination between 65{\textdegree} and
75{\textdegree} to complement GRACE-C, launching in the early
2030s. NGGM offers the possibility for reduced noise in
measuring short-period variations in the satellite separation
using an improved accelerometer relative to what is flying on
GRACE-C. One pathway for this is by using a simplified version
of the Gravitational Reference Sensors demonstrated on the LISA
Pathfinder Mission in 2016. And, if the measurement accuracy is
much improved, it appears desirable to fly NGGM with a fixed
ground track and an approximately 5-day orbit repeat period.}",
