# Investigations into the unexpected Delta-V increases during the Earth gravity assists of Galileo and NEAR

Peter Antreasian, Joseph Guinn, 1998. _AIAA/AAS Astrodynamics Specialist Conference and Exhibit, AIAA 98-4287_.

The JPL navigation analysis that first reported the anomaly, with a re-analysis of both Galileo flybys and the NEAR flyby using the best Earth gravity field of August 1998; dismissed lunar, solar and relativistic causes.
