Spacecraft that orbit around Earth do so in two types of orbits: circular and elliptical. In a circular orbit, the spacecraft is always at the same distance from the center of the Earth.

The European Space Agency 's (ESA) Proba-3 mission, consisting of two spacecraft called the Occulter and the Coronagraph, ...

2 National Research Institute of Astronomy and Geophysics (NRIAG), Cairo, Egypt. This paper investigates the chaotic behavior of an electrodynamic tethered satellite system (ETSS) orbiting Earth in an ...

In space, aerobraking can change the orbit of a spacecraft while minimizing the use of its propulsion system and fuel. The closest point in an elliptical orbit around Earth, where the satellite or ...

Abstract: We propose a novel scheme for surveillance of a dynamic ground convoy moving along a non-linear trajectory, by aerial agents that maintain a uniformly spaced formation on a time-varying ...

ABSTRACT: This paper investigates the chaotic behavior of an electrodynamic tethered satellite system (ETSS) orbiting Earth in an inclined elliptical orbit. The system is modelled using a dumbbell ...

Specifically, the nonlinear dynamics describing the motion of a follower spacecraft relative to a leader spacecraft are developed for the case where the leader spacecraft is in an elliptical orbit.

"And so it wasn't getting fast enough to reach escape velocity. And so it ended up in a big elliptical orbit around the Earth." Sponsor Message McDowell says it's hard to predict where exactly on ...

leaving the craft with just enough velocity to be marooned in an elliptical orbit around our planet. Now, less than 5,000 miles (8,000 kilometers) from where it first launched from Kazakhstan's ...
