NASA's current human spaceflight goal is Mars, but the Trump administration could change that to the Moon. Is that a good idea? Here's an in-depth look at the differences in science gain, the arguments for and against a potential commercial market, and whether or not the technological and operational challenges required to reach the Moon apply to Mars.
International Space Station (ISS) project partners are inching ever closer toward an agreement to begin the development of a new human outpost in the vicinity of the Moon. If successful, the cis-lunar space station (a space station in the vicinity of the Moon) will be the largest international space project to date, influencing the direction of human space flight for decades to come.
SpaceX's plans to colonize Mars differ considerably from NASA's Journey to Mars ambitions. But direct comparison is difficult. SpaceX is able to wipe the slate clean and start fresh with a bold new approach to humans in space. NASA has no such luxury, and must use existing pieces and people to make their goals a reality.
