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…
Energy relaxation in superthermal collisions of carbon with oxygen: the influence of isotopic substitution
Cheikh T. Bop, Marko Gacesa
The transition from a once-dense Martian atmosphere to the thin one observed today implies a substantial loss of carbon, either through atmospheric escape or surface deposition. Ac…
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…
Energetic proton losses reveal Io's extended and longitudinally asymmetrical atmosphere
H. L. F. Huybrighs, C. P. A. van Buchem, A. Blöcker +3
Along the I24, I27 and I31 flybys of Io (1999-2001), the Energetic Particle Detector (EPD) onboard the Galileo spacecraft observed localised regions of energetic protons losses (15…
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-…
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…
Mass supply from Io to Jupiter's magnetosphere
L. Roth, A. Blöcker, K. de Kleer +24
Since the Voyager mission flybys in 1979, we have known the moon Io to be both volcanically active and the main source of plasma in the vast magnetosphere of Jupiter. Material lost…
Cometary surface dust layers built out of millimetre-scale aggregates: dependence of modelled cometary gas production on the layer transport properties
Yu. Skorov, J. Markkanen, V. Reshetnyk +5
The standard approach to obtaining knowledge about the properties of the surface layer of a comet from observations of gas production consists of two stages. First, various thermop…
Statistical Study of Uncontrolled Geostationary Satellites Near an Unstable Equilibrium Point
Roberto Flores, Mauro Pontani, Elena Fantino
The growth of the population of space debris in the geostationary ring and the resulting threat to active satellites require insight into the dynamics of uncontrolled objects in th…
End-to-end trajectory concept for close exploration of Saturn's Inner Large Moons
Elena Fantino, Burhani M. Burhani, Roberto Flores +3
We present a trajectory concept for a small mission to the four inner large satellites of Saturn. Leveraging the high efficiency of electric propulsion, the concept enables orbit i…
In-situ detection of Europa's water plumes is harder than previously thought
Rowan Dayton-Oxland, Hans L. F. Huybrighs, Thomas O. Winterhalder +2
Europa's subsurface ocean is a potential candidate for life in the outer solar system. It is thought that plumes may exist which eject ocean material out into space, which may be d…
CO2-driven surface changes in the Hapi region on Comet 67P/Churyumov-Gerasimenko
Björn J. R. Davidsson, F. Peter Schloerb, Sonia Fornasier +24
Between 2014 December 31 and 2015 March 17, the OSIRIS cameras on Rosetta documented the growth of a 140m wide and 0.5m deep depression in the Hapi region on Comet 67P/Churyumov-Ge…
Migrating Thermal Tides in the Martian Atmosphere during Aphelion Season Observed by EMM/EMIRS
Siteng Fan, François Forget, Michael D. Smith +11
Temperature profiles retrieved using the first set of data of the Emirates Mars InfraRed Spectrometer (EMIRS) obtained during the science phase of the Emirates Mars Mission (EMM) a…
Model for Nitric oxide and its dayglow emission in the Martian upper atmosphere using NGIMS/MAVEN measured neutral and ion densities
Susarla Raghuram, Anil Bhardwaj, Maneesha Dharwan
A comprehensive study of Nitric oxide (NO) chemistry in the Martian upper atmosphere is restricted due to the lack of requisite measurements. NO is an abundant form of odd nitrogen…
Transfer design between neighborhoods of planetary moons in the circular restricted three-body problem
David Canales, Kathleen C. Howell, Elena Fantino
Given the interest in future space missions devoted to the exploration of key moons in the solar system and that may involve libration point orbits, an efficient design strategy fo…
A Method for Accurate and Efficient Propagation of Satellite Orbits: A Case Study for a Molniya Orbit
Roberto Flores, Burhani Makame Burhani, Elena Fantino
Fast and precise propagation of satellite orbits is required for mission design, orbit determination and payload data analysis. We present a method to improve the computational per…
Feasibility Study of Aerocapture at Mars with an Innovative Deployable Heat Shield
Giorgio Isoletta, Michele Grassi, Elena Fantino +2
Performing orbital insertion around Mars using aerocapture instead of a propulsive orbit insertion manoeuvre allows to save resources and/or increase the payload mass fraction. Aer…
Long-Term Orbit Dynamics of Decommissioned Geostationary Satellites
Simone Proietti, Roberto Flores, Elena Fantino +1
In nominal mission scenarios, geostationary satellites perform end-of-life orbit maneuvers to reach suitable disposal orbits, where they do not interfere with operational satellite…
An Automatic Tree Search Algorithm for the Tisserand Graph
D. de la Torre Sangrà, E. Fantino, R. Flores +2
The Tisserand graph (TG) is a graphical tool commonly employed in the preliminary design of gravity-assisted trajectories. The TG is a two-dimensional map showing essential orbital…
