Low-Energy Round-Trip Trajectories to Near-Earth Objects using Low Thrust
Alessandro Beolchi, Mauro Pontani, Kathleen Howell +3
Near-Earth Objects (NEOs) are attractive exploration targets due to their accessibility, scientific value, and resources. Although trajectory design has revealed efficient pathways…
Low-Energy and Low-Thrust Exploration Tour of Saturnian Moons with Full Lunar Surface Coverage
Chiara Pozzi, Mauro Pontani, Alessandro Beolchi +2
This study presents the trajectory design for a mission touring Saturn's Inner Large Moons (Rhea, Dione, Tethys, Enceladus, and Mimas) engineered to meet observational requirements…
Uncontrolled geostationary satellites: mapping periodic transitions to chaos with Lagrangian Descriptors
Roberto Flores, Jerome Daquin, Mauro Pontani +2
Uncontrolled geostationary satellites abandoned near an unstable equilibrium point of the equator experience irregular transitions between dynamical states (continuous circulation,…
Design of a low-thrust gravity-assisted rendezvous trajectory to Halley's comet
Roberto Flores, Alessandro Beolchi, Elena Fantino +4
Comets are the most pristine planetesimals left from the formation of the Solar System. They carry unique information on the materials and the physical processes which led to the p…
Preparing for the 2061 return of Halley's comet -- A rendezvous mission with an innovative imaging system
Cesare Barbieri, Alessandro Beolchi, Ivano Bertini +5
The return of Comet 1P/Halley will promote a wide interest for ground and space observations of a celestial body of outstanding scientific and cultural interest. In addition to rem…
