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…
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…
The Dynamical State of the Didymos System Before and After the DART Impact
Derek C. Richardson, Harrison F. Agrusa, Brent Barbee +50
NASA's Double Asteroid Redirection Test (DART) spacecraft impacted Dimorphos, the natural satellite of (65803) Didymos, on 2022 September 26, as a first successful test of kinetic…
Time and frequency transfers in optical spacetime
Adrien Bourgoin, Pierre Teyssandier, Paolo Tortora +1
Solving the null geodesic equations for a ray of light is a difficult task even considering a stationary spacetime. The problem becomes even more difficult if the electromagnetic s…
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…
