Northrop Grumman, the manufacturer in its Grumman-guise of the world's only proven manned lunar lander, the Apollo programme's lunar excursion module (LEM), has been awarded a contract to provide design studies for another lunar lander - this time from the commercial lunar tourism firm, Golden Spike.
Golden Spike which in December 2012 announced plans to finance its project by offering lunar landing and exploration tickets to very high wealth individuals, shows a bubble shaped capsule configuration landing module on its website. This may not be how the final landing vehicle will look however.
