If the Trump administration succeeds in landing astronauts back on to the moon in , that would come at the tail end of what could be Trump's second term, if he gets reelected. The process of designing, engineering, and testing a spacecraft that could get people to another world easily outlasts a two-term president. But incoming presidents and lawmakers often scrap the previous leader's space-exploration priorities. In , for example, the Bush administration tasked NASA with coming up with a way to replace the space shuttle, which was set to retire, and also return to the moon.
The agency came up with the Constellation program to land astronauts on the moon using a rocket called Ares and a spaceship called Orion. Trump hasn't scrapped SLS. But he did change Obama's goal of launching astronauts to an asteroid , shifting priorities to moon and Mars missions. I'll just see things as they come. Buzz Aldrin said in testimony to Congress in that he believes the will to return to the moon must come from Capitol Hill. We demonstrated that for a brief time 45 years ago.
I do not believe we have done it since," Aldrin wrote in a statement. The real driving force behind that government commitment to return to the moon is the will of the American people, who vote for politicians and help shape their policy priorities. But public interest in lunar exploration has always been lukewarm. The political tug-of-war over NASA's mission and budget isn't the only reason people haven't returned to the moon.
The moon is also a 4. Its surface is littered with craters and boulders that threaten safe landings. Leading up to the first moon landing in , the US government spent what would be billions in today's dollars to develop, launch, and deliver satellites to the moon to map its surface and help mission planners scout for possible Apollo landing sites.
But a bigger worry is what eons of meteorite impacts have created: regolith, also called moon dust. Madhu Thangavelu , an aeronautical engineer at the University of Southern California, wrote in that the moon is covered in "a fine, talc-like top layer of lunar dust, several inches deep in some regions, which is electrostatically charged through interaction with the solar wind and is very abrasive and clingy, fouling up spacesuits, vehicles and systems very quickly.
Peggy Whitson , an astronaut who lived in space for a total of days, previously told Business Insider that the Apollo missions "had a lot of problems with dust. Basically, the shorter the program is, the less time it takes, the less political risk we endure. In other words, we can accomplish the end state.
The landing is part of a program called Artemis , which aims to build up a long-term, sustainable human presence at and around the moon. The main goal is to lay the foundation for crewed trips to the ultimate human-spaceflight destination: Mars. Follow him on Twitter michaeldwall. Follow us on Twitter Spacedotcom or Facebook.
