Optimal Low-Thrust Orbit Transfers Connecting Gateway with Earth and Moon
Chiara Pozzi, Mauro Pontani, Alessandro Beolchi +1
Gateway will represent a primary logistic infrastructure in cislunar space. The identification of efficient orbit transfers capable of connecting Earth, Moon, and Gateway paves the…
Direct low-energy trajectories to Near-Earth Objects
Elena Fantino, Roberto Flores, Giuseppe Donnarumma +2
Near-Earth Objects (NEOs) are asteroids, comets and meteoroids in heliocentric orbits with perihelion below 1.3 au. Similarly to the population of the Main Asteroid Belt, NEOs are…
Multiple-arc optimization of low-thrust earth-moon orbit transfers leveraging implicit costate transformation
Alessandro Beolchi, Mauro Pontani, Chiara Pozzi +1
This work focuses on minimum-time low-thrust orbit transfers from a prescribed low Earth orbit to a specified low lunar orbit. The well-established indirect formulation of minimum-…
Optimization, guidance, and control of low-thrust transfers from the Lunar Gateway to low lunar orbit
Chiara Pozzi, Mauro Pontani, Alessandro Beolchi +1
The Gateway will represent a primary space system useful for the Artemis program, Earth-Moon transportation, and deep space exploration. It is expected to serve as a staging locati…
Orbital perturbation coupling of primary oblateness and solar radiation pressure
Martin Lara, Elena Fantino, Roberto Flores
Solar radiation pressure can have a substantial long-term effect on the orbits of high area-to-mass ratio spacecraft, such as solar sails. We present a study of the coupling betwee…
Computing Classical Orbital Elements with Improved Efficiency and Accuracy
Roberto Flores, Elena Fantino
This paper reviews the standard algorithm for converting spacecraft state vectors to Keplerian orbital elements with a focus on its computer implementation. It analyzes the shortco…
