... '''Number of Pages''' - 9 Abstract Next-generation space exploration will most likely require the on-orbit assembly of large spacecraft. 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 ...

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 ...

... of Pages''' - 2 Abstract Arthur C. Clarke's name is often linked with the Geostationary orbit as a result of his 1945 paper in Wireless World. Less well-known is where the credit for discovering the Molniya orbit should lie. This paper presents the evidence uncovered to date concerning the original concept and provides some insight into the ways in which the orbit has subsequently been exploited.
