Milani and Juventas Optical Navigation Images in Support of the Hera Radio Science Experiment
Edoardo Gramigna, Ozgur Karatekin, Birgit Ritter +7
The European Space Agency's Hera mission aims to advance planetary defense by investigating the Didymos binary asteroid system following NASA's DART impact on Dimorphos. Incorporat…
Hera Orbit Determination Covariance Analysis of Didymos Binary Asteroid with the Full Two-Body Problem
Edoardo Gramigna, Riccardo Lasagni Manghi, Marco Zannoni +7
Standard planetary radio science analyses may be inadequate for accurately interpreting data from the Hera mission at the Didymos system due to the anticipated challenge posed by t…
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…
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
This work presents the simulation results of the radio science experiment onboard the proposed Heavy Metal mission to the M-type asteroid (216) Kleopatra. Earth-based radiometric m…
Varying water activity and momentum transfer on comet 67P/Churyumov-Gerasimenko from its non-gravitational forces and torques
N. Attree, P. Gutiérrez, O. Groussin +9
We investigate the ability of a simultaneous fitting of comet 67P/Churyumov-Gerasimenko's non-gravitational forces, torques and total water-outgassing rate, as observed by Rosetta,…
Ephemeris Reconstruction for Comet 67P/Churyumov-Gerasimenko During Rosetta Proximity Phase from Radiometric Data Analysis
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…
Activity distribution of comet 67P/Churyumov-Gerasimenko from combined measurements of non-gravitational forces and torques
Nicholas Attree, Laurent Jorda, Olivier Groussin +5
Aims. Understanding the activity is vital for deciphering the structure, formation, and evolution of comets. We investigate models of cometary activity by comparing them to the dyn…
