The Gravity Field and Interior Structure of Enceladus
Inside Enceladus Saturn's moon Enceladus has often been the focus of flybys of the Cassini spacecraft. Although small—Enceladus is roughly 10 times smaller than Saturn's largest moon, Titan—EnceladusExpand

TIME-DELAY INTERFEROMETRY FOR SPACE-BASED GRAVITATIONAL WAVE SEARCHES
Ground-based, equal-arm-length laser interferometers are being built to measure high-frequency astrophysical gravitational waves. Because of the arm-length equality, laser light experiences the sameExpand

Spacecraft Doppler tracking: Noise budget and accuracy achievable in precision radio science observations
[1] We discuss noise in Doppler tracking of deep space probes and provide a detailed noise model for Doppler radio science experiments. The most sensitive current experiments achieve fractionalExpand
