In order for any such exploration program to be sustainable, it ... , and in-space refuelling are modelled and compared in terms of mass-to-orbit requirements for various on-orbit assembly tasks. Results show that reusable space tugs with in-space refuelling can ...

... hybrid direct-indirect optimization algorithm is presented to compute the minimum-time transfer between two orbits, including the phasing with a desired spacecraft. Very-low thrust means several hundred revolutions to perform the large change in orbital elements. The optimal control solution of the fast-evolution problem combined with a direct method ...

... propulsion system or thrusters on board that would be used to maintain their position in orbit. The thrusters would only be used occasionally to maintain correct position because the module would be orbiting around Earth and the gravitational pull would keep it in place. At first, the modules ...

... jump out and slide down a slide wire to the ground. After launch, if the orbiter can be put into a shallow glide, the astronauts can extend a pole out the ... a little way, and then parachute to the ground. Higher up in the ascent the orbiter can abort to the launch site, or abort to a landing site in Africa or Europe, or even make it to orbit. In other words, there are several methods of escape depending on where and when the ...

We need to go about 17,000 miles per hour to orbit and to maintain a space orbit. There is a range of speeds at which the different satellites travel. Because of ... in space we are. So if we want to put a satellite in a different orbit, we make sure that it has different speeds and orientation from those of the other ...
