This is great news, if the fuel cost of going between points in our solar system can be reduced there should be a greater incentive to commercialize it.
ANDREWS SPACE OF SEATTLE has awarded SpaceDev a contract to design a small spacecraft to travel through a gravity tunnel – part of the InterPlanetary Superhighway or IPS, a route that eats up less fuel than normal trajectories – to the moon, for the very first time ever.
Small spaceship to fly through gravity tunnel
The SpaceDev web site also has a lunar lander program that you can try out if your running Windows. Looks ok, think of the classic lunar lander game but with 3D graphics.
