NASA carried out one more launch to map the surface of the Moon and search for water – it was an unmanned Atlas rocket. The objective is to send astronauts once again to the Moon in 2020. The journey to the Moon would take around four days. The Project Manager said that the knowledge on Moon is far less as compared to what is available for Mars, hence the curiosity. The probe would try to locate minerals, make detailed maps of the temperature, identify locations on the surface that experiences maximum sunlight and chart the topography. NASA expects future expeditions to have more members and remain there for longer periods. The landing sites might be chosen as the Polar Regions which might reveal sources of frozen water.
