Gravity Science (GRAV)

NSSDCA ID: 2011-040A-09

Mission Name: Juno
Principal Investigator:Dr. William M. Folkner


The Gravity Science (GRAV) investigation was designed to use the X and Ka-band transponders on-board the Juno spacecraft and Doppler tracking equipment at the Deep Space Network to perform radio science investigations to very precisely map the gravitational field of Jupiter. Objectives include determining the structure of Jupiter's interior and deriving normalized gravity coefficients J4, J6, and J8 through J14.
