(Bloomberg) — SpaceX CEO Elon Musk recommended hastening the end of the International Space Station on his social media site X, arguing that the orbiting laboratory should be taken out of orbit within two years instead of the current five-year target.
“The decision is up to the President, but my recommendation is as soon as possible,” Musk wrote on his social media site X. He argued that the ISS “has served its purpose” and that there “is very little incremental utility.”
Musk then reiterated his ultimate plan: “Let’s go to Mars.”
Built in partnership with the Canadian, European, Japanese and Russian space agencies, the International Space Station has been a staple of NASA’s human spaceflight initiatives for the last three decades, serving as the primary location where astronauts live and conduct research in orbit.
Since November of 2000, the ISS has always had at least one crew member on board at all times.
The Biden administration in 2021 extended the planned lifetime of the ISS through the end of 2030, and last June awarded Musk’s SpaceX a $843 million contract to develop a spacecraft that could attach to the ISS and guide it out of orbit then. Such a disposal would cause the ISS to break up as it plunges through the atmosphere.
The spacecraft is also meant to guide the ISS to an unpopulated area of the Earth so that any surviving pieces do not pose a risk to people on the ground.
SpaceX is a major partner on the ISS program, with NASA contracts to deliver astronauts and cargo to the station.
NASA did not immediately respond to a request for comment on Musk’s X posts.
As the leader of the government cost cutting effort known as the Department of Government Efficiency, Musk has established himself as one of President Donald Trump’s top advisers.
Responding to a question about conflicts of interest involving Musk and his companies, Trump said on Tuesday that he would not let the world’s richest person partake in government work related to space.
If Trump takes Musk’s recommendation, ending the ISS program ahead of schedule may prove controversial with lawmakers in Congress, who are responsible for funding NASA’s programs.
Senator Ted Cruz, the Texas Republican who is chairman of the Senate Commerce, Science and Transportation Committee, recently called for a renewed focus on the ISS and developing commercial space stations in low Earth orbit.
“One of my top near-term priorities is ensuring that we do not cede American leadership in low Earth orbit,” Cruz said on Feb. 12 at an industry conference in Washington DC. “We’ve invested more than $100 billion into the International Space Station, and it would be exceptionally foolhardy to prematurely send all that infrastructure and all those tax dollars to the bottom of the ocean.”
In preparation for the ISS’s retirement, NASA is funding the development of commercial space stations that astronauts can visit in the future. NASA plans to award final contracts for these ISS replacements in 2026.
