Lunar Orbital Platform-Gateway

United States going to build Lunar Orbital Platform-Gateway costing 2.7B$

The Lunar Orbital Platform-Gateway was one of several projects funded in President Donald Trump’s $19.9 billion NASA budget proposal for 2019. It would work similarly to the International Space Station. The lunar platform will orbit the moon not the Earth. It is going to finish by 2023. Robert Lightfoot, NASA’s acting administrator, said “The platform would “help us further explore the moon and its resources and translate that experience toward human missions to Mars”. The power and propulsion element is going to lunch in 2022. This element would use solar electric propulsion to keep the gateway in the appropriate position in space. It also would provide space  to Earth, space to lunar and spacecraft to spacecraft communications, as well as support communication for spacewalks. Lasers would be transferred according to a Feb. 13 NASA web post. In accordance with NASA the habitation of the platform is planned to launch in 2023: one year later. It is because that the staff can love and work there for 30 to 60 days at a time. Nowadays, many corporations of U.S are joining in studies on how to improve the two separate elements, the habitant and power and propulsion elements. Boeing of Houston is complicated in both. Mark Ortiz, Boeing’s Next STEP (Next Space Technologies for Exploration Partnerships) program manager mentioned “The intent is to have as much realism in the habitation module as possible, by integrating all the racks and human factors, from galleys to sleep stations, glove boxes and command and control systems and displays”. “Some things, of course, will be different because of the location of the lunar gateway. For example, there are higher levels of radiation near the moon compared to what the space station is exposed to in its low Earth orbit. So, astronauts on the lunar gateway will need to have adequate radiation protection”. Ortiz said.
The power and propulsion element works are going to start in November 2017 when NASA selected five companies including Boeing to participate in four-month studies. By the way it will be launched either by the Space Launch System rocket being developed by NASA or by commercial rockets.
