In this paper we present a study of collisional dynamics between space debris and a operational vehicle in LEO. We adopted an approach based on the relative dynamics between the objects on a collisional course and with a short warning time and establish a semi-analytical solution for the final trajectories of these objects. Our results show that there are angular ranges in 3D, in additio…
In orbital dynamics, minor bodies are those that have size (and mass) much smaller than at least one of the other bodies (called primaries) of the system that belong to. One case very common in astronautics is the case of a spacecraft traveling within the Earth-Moon system. This kind of characteristic makes the dynamics of the system to present some peculiarities. One of them is the fact …
The formation of regular satellites of gas planets in the solar system is explained by two main models. These models explain the formations of the Galilean satellites and Titan, as they occurred in a circumplanetary accretion disk composed of gas and solids around Jupiter and Saturn, respectively, in the first million years of the solar system. the minimum mass subnebula model was propose…
There are two classical models that explain the formation of the regular satellites of the giant planets of our Solar System. The minimum mass model proposed by Lunine and Stevenson (1982), which could be interpreted as a equivalent to the formation of the planets, but on the circumplanetary disk scale. And the gas-starved model proposed by Canup and Ward (2002), in which the material tha…
In an orbital transfer the acquisition of orbit is the last step of the process. It occurs when the thrusters are activated, consuming the spacecraft's fuel and reducing its velocity. In this project we propose to study a method of orbit acquisition that consist of the break of a tether joining two bodies. This break produces orbital energy exchanges so that one of the particles gains ene…

For three centuries astronomers and mathematicians have studied the problem of the formation and evolution of the Solar System. One way to study the formation of the Solar System is throughnumerical simulations. The Nice model is a scientific model to describe the dynamical evolution of the Solar System by simulation of the interaction of the gravitational N-body problem. The Nice model e…
The formation of the regular satellites are one of the most intriguing problem of the astronomy, the physical effects that led such large bodies grows close to planets are not completely understood yet. One way to study the formation of those bodies is through numerical simulations. In the past few decades the number of computational tools for astronomy increase substantially, however the…
Fragmentation dynamics of fuzzy aggregates upon collision is studied in the contextof the kinetic description of planetary rings. We elaborate a fragmentationmodel which gives the distribution function for the velocities and masses of debrisproduced in collisions. These quantities are expressed in terms of the kinetic energyof colliding particles, the material properties of the particles …
