A Korean team has independently developed and tested a small unmanned lunar module. The lunar module can travel to the moon from the earth’s orbit and land on the moon’s surface with its own engine propulsion. The Korean lunar module measures 40 cm by 40 cm and consists of a propulsion engine and a control system. It can land on the moon’s surface using its four legs. The engine also reduces the speed for the moon landing.
The Korean lunar module can be carried on a rocket into the earth’s orbit and propel itself on into lunar orbit from there with its own engine several times. By using environment-friendly fuel, the Korean lunar module roughly costs half ($50 million) when compared with the cost of an American lunar module ($100 million).
