NASA announced it would soon leave the ISS, hoping to return to the Moon

During the NASA Advisory Council meeting earlier this month, the head of flights into human space - William Gerstenmaier, said: "We will leave ISS as soon as possible" , according to Ars Technica. After giving up its position on the space station, the US Aeronautics and Space Agency hopes to return to the destination that astronauts have not approached any more since 1972: The Moon .

There is no clear information yet whether astronauts set foot on the moon. However, one thing is clear: NASA wants to launch manned spacecraft into orbit around the moon (the space between the earth and the moon) in the late 2020s. Leaving ISS, astronauts have can go from day to day from Earth. They will also be protected by the planet's shield, from most dangerous high-energy radiation from the sun.

These factors make astronauts better living, both psychologically and physiologically and preparing for trips to Mars.Long stays in the space between the Earth and the Moon will be the next step in the process of bringing people to Mars. For NASA, ISS (International Space Station) is a costly effort. In 2015, this space agency spent $ 3 billion on the International Space Station, accounting for one-sixth of the total $ 18 billion in budget. Moreover, these costs are expected to increase in the next few years.

NASA cannot afford to maintain their presence on ISS, and implement its plans to pursue the ultimate goal of the Moon or Mars. They had to make a choice, and Gerstenmaier, who had a voice in weight at the NASA space agency, had made very clear decisions. As planned, NASA will continue its partnership on ISS until 2024.
