[IGSMAIL-8398] EGU24, Session PS1.4: The future of geodesy at Mars

[weigelt at ife.uni-hannover.de]

Dear colleagues,

 

we would like to draw your attention to Geodesy on Mars and invite you to
submit your contribution to the session PS1.4 “The future of geodesy at
Mars”. Although the primary focus is gravimetry, contributions leading to
better observations of Mars are very welcome. 

 

Geodetic measurements from space missions to distant worlds have revealed
oceans of liquid water within icy moons, probed the atmospheric dynamics of
gas giants, and characterized the deep structure of terrestrial worlds. The
power of geodesy is best demonstrated at the Earth and Moon, where
spacecraft missions have transformed geodesy from a purely geophysical tool
into one that unlocks advances in geology, climate change, hydrology,
geochemistry, and more. While geodesy in the Earth-Moon system has
flourished with the GRACE, GOCE and GRAIL gravity mapping missions, geodesy
at Mars has lagged behind. The NASA’s Insight mission has shown that the
interior of Mars is seismically active. However, important questions about
the Martian crustal structure remain unanswered. New geodetic data from a
dedicated gravity mapping mission could be used to locate hidden water
resources on Mars, elucidate the nature of Martian crustal dichotomy as well
as reveal the connections between Martian climate and orbital dynamics.

This session aims to explore the scientific gain from the next generation
gravimetry at Mars as well as to start the discussion on measurement
requirements necessary to create lasting benefit. The session welcomes
contributions on current solid Mars research, mass change due to the
dynamics of volatiles, as well as synergies between gravity mapping and
other remote and in-situ observations of Mars.

 

On behalf of the conveners, Matthias Weigelt
