Quantification of Tides in Giant Planets from Observations
Valéry Lainey, Marco Zannoni, Vincent Robert +1
Quantifying tidal effects on giant planets has recently made significant advances, thanks in particular to the Cassini space probe. During its thirteen-year orbit around Saturn, nu…
A novel pointing technique for the enhancement of Tropospheric Delay Calibration System performances
David Bernacchia, Riccardo Lasagni Manghi, Marco Zannoni +5
The beam-crossing is a novel technique aimed at reducing residual tropospheric Doppler noise for microwave radiometer calibrations. In this work, we report the findings of the firs…
Stellar occultations in support of the LUMIO orbit determination
Davide Banzi, Riccardo Lasagni Manghi, Marco Zannoni
This work investigates the use of stellar occultation measurements to enhance the orbit determination performance of the Lunar Meteoroid Impact Observer (LUMIO) mission, operating…
High-Speed Boulders and the Debris Field in DART Ejecta
Tony L. Farnham, Jessica M. Sunshine, Masatoshi Hirabayashi +44
On 26 September 2022 the Double Asteroid Redirection Test (DART) spacecraft collided with Dimorphos, the moon of the near-Earth asteroid 65803 Didymos, in a full-scale demonstratio…
A Radio Science Experiment for the Ramses Mission to Apophis
Riccardo Lasagni Manghi, Marco Zannoni, Edoardo Gramigna +6
This paper outlines the Radio Science Experiment (RSE) proposed for the RAMSES mission to asteroid (99942) Apophis, which will undergo a close Earth encounter in April 2029. This e…
Radio Science Investigations for the Heavy Metal Mission to Asteroid (216) Kleopatra
Paolo Tortora, Riccardo Lasagni Manghi, Edoardo Gramigna +3

Riccardo Lasagni Manghi, Marco Zannoni, Paolo Tortora +3
This study provides a continuous ephemeris reconstruction for comet 67P/Churyumov-Gerasimenko by reanalyzing Rosetta radiometric measurements and Earth-based astrometry. Given the…
The Hera Radio Science Experiment at Didymos
Edoardo Gramigna, Riccardo Lasagni Manghi, Marco Zannoni +7
Hera represents the European Space Agency's inaugural planetary defense space mission and plays a pivotal role in the Asteroid Impact and Deflection Assessment international collab…
Combining astrometry and JUICE -- Europa Clipper radio science to improve the ephemerides of the Galilean moons
M. Fayolle, A. Magnanini, V. Lainey +3
The upcoming JUICE and Europa Clipper missions to Jupiter's Galilean satellites will provide radio science tracking measurements of both spacecraft. Such data are expected to signi…
Momentum Transfer from the DART Mission Kinetic Impact on Asteroid Dimorphos
Andrew F. Cheng, Harrison F. Agrusa, Brent W. Barbee +66
The NASA Double Asteroid Redirection Test (DART) mission performed a kinetic impact on asteroid Dimorphos, the satellite of the binary asteroid (65803) Didymos, at 23:14 UTC on Sep…
Activity distribution of comet 67P/Churyumov-Gerasimenko from combined measurements of non-gravitational forces and torques
