In this paper, the problem of autonomous optimal absolute orbit keeping for a satellite mission in Low Earth Orbit using electric propulsion is considered. The main peculiarity of the approach is to support small satellite missions in which the platf

For the $N$ -impulse transfer between two earth orbits, this paper introduces $N - 1$ intermediate orbits to describe the orbit transfer scheme. The eccentricity vector of the intermediate orbits and the true anomalies corresponding to the impulsive

The aim of this chapter is to determine a preliminary orbit of Mars. The method of Herget is used and adapted slightly to obviate the need for a numerical differentiation. Lagrange’s f and g functions are introduced. A method is borrowed from Escob

In heavy-ion collisions, the harmonic flow $V_n$ of final-state particles are driven by the eccentricity vector ${\mathcal{E}}_n$ that describe the shape of the initial fireball projected in the transverse plane. It is realized recently that the stru

This paper develops a general method to execute orbital rendezvous in continuation of previous work, verifies it in simulations, and examines the effects of perturbations. The method uses a coordinate-free representation of the orbit as a basis for d

In this study, we investigate special families of frozen orbits for lunar artificial satellites. First, the Hamiltonian of a lunar artificial satellite is constructed. Next, the Hamiltonian is singly averaged by removing the short period coordinate w

The longitude of geostationary satellites is continuously drifting and oscillating under the impact of perturbation forces. This paper researched a periodic East–West Station-Keeping strategy to control the eccentricity and longitude simultaneously

In a recent paper Martin & Lubow showed that a circumbinary disc around an eccentric binary can undergo damped nodal oscillations that lead to the polar (perpendicular) alignment of the disc relative to the binary orbit. The disc angular momentum vec

We calculate the present-day impact flux on Mars and its variation over the Martian year, using the current data on the orbital distribution of known Mars-crossing minor planets. We adapt the {��}pik-Wetherill formulation for calculating collisio
