NASA AND THE SPACE LAUNCH SYSTEM.

Nasa is the acronym for National Aeronautics and Space Administration. It is the civil government agency responsible for the space program and aerospace research of the United States of America.

After the Apollo Program for the exploration of the Moon, space activity has developed through the program of the US orbital station SkyLab, the launch of numerous exploration missions of the solar system with automatic probes and the exploitation of Earth’s orbital space with shuttles Space Shuttle and supporting the construction of the ISS (International Space Station).

The loss of two Space Shuttles with their crews and budget cuts have led the agency to set aside plans for new lunar explorations and for sending astronauts to Mars, whose exploration will continue to be delegated to robotic systems.  On 14th September 2011, it announced that it had selected the design for a new manned transport system, called the Space Launch System, intended to take the place of the Space Shuttles.
