Massive Star Population in the Sextans A Dwarf Galaxy from HST UV Photometry
Roberto Flores, Elena Fantino, Giuseppina Battaglia +1
We build a catalog of massive (M>M) main sequence stars in the \mbox{metal-poor} (Z) dwarf irregular galaxy Sextans A. HST WFC3 UV photometry in the 2…
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…
