(Bloomberg) -- NASA's car-sized Perseverance rover has been roaming the surface of Mars for four years, drilling into the alien soil to collect dirt it places in tubes and leaves on the ground.

Engineers designed Perseverance to be the first step in the agency's exploration of the Red Planet. In the future, more robotic spacecraft would arrive to sweep up the capsules and rocket them back to Earth, where scientists could look for signs that Mars once was, or is, a world with life.
The wait for answers may be about to get longer. President Donald Trump's proposed 2026 budget for the US National Aeronautics and Space Administration would cancel the planned follow-on mission, potentially abandoning the tubes for decades to Martian dust storms.
The White House is calling for a roughly 50% cut to NASA's science spending to $3.9 billion, part of an overall pullback that would deliver the lowest funding level in the agency's history and kill more more than 40 NASA science missions and projects, according to detailed plans released last month. The Trump administration has also left the agency without a permanent leader and without a vision for how America's civilian space policy is going to work with US allies and compete with China and other rivals.
The cuts would follow a shift in how the American public thinks about space. NASA has long enjoyed a unique place in US culture, with its exploits celebrated by movies, theme parks and merchandise — but companies like Elon Musk's SpaceX have begun to capture more attention.
For decades, NASA's scientific undertakings have provided critical groundwork for researchers seeking to understand the structure of the universe, study how planets form and hunt for evidence that life might exist beyond Earth. Pictures from NASA craft like the Hubble Space Telescope and the recently launched James Webb Space Telescope have inspired and delighted millions.
Now, the agency's position at the vanguard of discovery is facing foreclosure. Among the other programs set to lose funding are a craft already on its way to rendezvous with an asteroid that's expected to pass close to Earth in 2029, and multiple efforts to map and explore the acidic clouds of Venus. Researchers worry that abandoning missions would mean investments made by earlier generations might be lost or forgotten.
'Once you launch and you're operating, then all those costs are behind you, and it's relatively inexpensive to just keep the missions going,' said Amanda Hendrix, the chief executive officer of the Planetary Science Institute, a nonprofit research organization. 'So I'm very concerned about these operating missions that are still producing excellent and really important science data.'
The Trump administration's narrower vision for NASA comes as it is seeking to reduce waste and jobs in the US government. Critics have faulted NASA over sluggish management of key programs, spiraling costs and delays.
Still, the administration is eager to pour more money into putting people in space. It wants to use $7 billion of the $18.8 billion it would allocate to NASA overall to ramp up efforts to return people to the moon, and invest $1 billion more in sending people to Mars.
'This is a NASA that would be primarily human spaceflight focused,' Casey Dreier, chief of space policy for The Planetary Society, a nonprofit that advocates for space science and exploration, said of the proposed changes. 'This is a NASA that would say, 'The universe is primarily the moon and Mars,' and basically step away from everything else.'
There are signs that the administration's proposed cutbacks won't satisfy lawmakers who view space as vital to US interests. Senator Ted Cruz, the Texas Republican who leads a committee that oversees NASA, has proposed legislation that would would provide nearly $10 billion to the agency.
'American dominance in space is a national security imperative,' Cruz said in a statement to Bloomberg. 'The Commerce Committee's bill carefully invests in beating China to the Moon and Mars — while respecting every taxpayer dollar. It's rocket fuel for the commercial space companies and NASA that are working to keep America ahead of China in the Space Race.'
As Trump's spending proposal moves through Congress, NASA has been left without a strong leader who can press its case after the president withdrew his nomination of billionaire commercial astronaut Jared Isaacman to run the agency.
In a recent interview on the All-In Podcast, Isaacman appeared to suggest Trump pulled his nomination because of his close ties to Musk, who had a public falling out with the president. Trump threatened to cancel SpaceX's government contracts amid the row, but has since backed down.
'Stopping Jared from becoming confirmed is only going to hurt NASA's ability to push back on budget cuts,' Jim Muncy, a space consultant and lobbyist with PoliSpace, said before Isaacman's nomination was pulled.
Spaceflight Shift
For decades, NASA handled every step of launching rockets, probes and people into space, from developing, building and launching vehicles, to running missions. Only the government had the resources and the capacity to shoulder the risks without returning a profit.
That all changed in recent years with the emergence of a vibrant US space industry dominated by wealthy entrepreneurs with a passion for spaceflight and the financial wherewithal to withstand repeated failure.
Over time, NASA has ceded more design, development and production work to those companies. SpaceX is carrying cargo and astronauts to the International Space Station, and sending probes into deep space from a rented launchpad at NASA's Kennedy Space Center. After helping to spur the development of SpaceX hardware, NASA is now one of the company's biggest customers.
'This has kind of been the tension with the rise of commercial space,' said Mike French, a consultant for the Space Policy Group. 'NASA has gone from 'We're operating these things; we're building these things' to 'We've gotten really good at buying these things.''
During Trump's presidency, NASA's transformation into an incubator for private industry is likely to gain speed. Throughout its budget proposal, the White House calls for mimicking past programs that have leaned more on outsourcing to the private sector.
'With a leaner budget across all of government, we are all taking a closer look at how we work, where we invest, and how we adjust our methods to accomplish our mission,' NASA's acting administrator, Janet Petro, wrote in a message accompanying the plan. 'At NASA, that means placing a renewed emphasis on human spaceflight, increasing investments in a sustainable plan to return to the Moon for long-term human exploration and accelerating efforts to send American astronauts to Mars.'
NASA declined to comment beyond Petro's statement.
NASA contracts remain one of the most significant and steady sources of funding for the space industry, which has allowed the agency to set the direction for many businesses. But that balance of power is shifting, and cuts to NASA's funding could cause its leadership to fade.
'NASA would, in a sense, define access and define the culture of spaceflight and define the ambitions of spaceflight,' Dreier said. 'Now, they have competitors for that, and frankly, some of their competitors are laying out more ambitious programs.'
Challenging Missions
While NASA has evolved into a technical adviser and financial backer for space companies, pure science has remained part of its mission. NASA's transition to more commercial partnerships was started, in part, to free up money to spend on exotic, challenging missions with no obvious near-term commercial rewards.
Pulling back is likely to have consequences. Trump's broader push to curtail funding for science — the administration has choked off money for medical, climate and other research — risks eroding an important source of American soft power.
After the end of the Cold War-era space race, NASA became a vessel for international cooperation, proving countries with lofty goals can work together. Many of the NASA missions Trump has proposed canceling or pulling away from entailed collaboration with European allies.
The prospect of reduced funding is also causing worry about agency talent. Already, NASA is competing with the private space industry for engineers. Shutting down missions could push agency scientists to seek other opportunities.
'Folks are very worried about what they're going to do now with their lives, and where they're going to go,' said Hendrix, the Planetary Science Institute's CEO.
The long-term outlook for NASA is difficult to discern. In the coming years, it is expected to continue its Artemis moon program, and start a new program for human exploration of Mars, with commercial companies at the forefront. But the scientific ambitions that long helped define NASA appear likely to become more limited.
'If we elect to say we no longer want to understand our origins, or we no longer want to challenge ourselves to see if there's life out in the cosmos, that is the equivalent of turning our heads down and burying ourselves in our cell phones when we're standing at the edge of the Grand Canyon,' said The Planetary Society's Dreier. 'We miss something more profound and big and deep that we otherwise have no access to in our modern society.'
