To launch the Europa Clipper mission, the US Space Agency decided to use a commercial rocket. Previously, the promising Space Launch System was considered as a carrier.
The Space Launch System is one of NASA's key projects and the most powerful launch vehicle of the foreseeable future. However, the US Space Agency refused to use it to launch Europa Clipper. Now they want to use a private launch vehicle for this.
Europa Clipper is an automatic interplanetary station that will have to explore Jupiter's moon Europa. The focus is on his ability to maintain life. The complex includes an orbiter and a lander. The launch date was previously called 2024.
