Scientists at NASA are working on a new mission concept that would use a tether and harpoon to reel a robotic spacecraft in for a landing on a comet or asteroid. This Comet Hitchhiker concept could allow a craft to get into orbit and land on small bodies to study them from close range. In order to land on a comet or asteroid, the Comet Hitchhiker needs to shoot its harpoon into the body and then eventually reel itself in. Scientists are still trying to gauge the feasibility of a mission and they have done some supercomputer simulations. Read More>>
