Scientists have developed a new method using knot theory to find the optimal routes for future space missions without the need to waste fuel.
Just as sat-nav did away with the need to argue over the best route home, scientists from the University of Surrey have developed a new method to find the optimal routes for future space missions without the need to waste fuel.
One way of doing this is to find 'heteroclinic connections' -- the paths that allow spacecraft to transfer from one orbit to another without using fuel. The technique was tested successfully on various planetary systems -- including the Moon, and the Galilean moons of Jupiter. Both of these are the focus of current and future missions."Spurred on by NASA's Artemis programme, the new Moon race is inspiring mission designers around the world to research fuel-efficient routes that can better and more efficiently explore the vicinity of the Moon.
