    Sensitivity analysis of polar orbiter motion to lunar viscoelastic tidal deformation

    We investigate the impact of viscoelastic tidal deformation of the Moon on the motion of a polar orbiter. The dissipative effects in the Moon’s interior, i.e., tidal phase lags, are modeled as Fourier series s...

    Mercury’s resonant rotation from secular orbital elements

    We used recently produced Solar System ephemerides, which incorporate 2 years of ranging observations to the MESSENGER spacecraft, to extract the secular orbital elements for Mercury and associated uncertainti...
