Trump's proposed satellite cuts raise questions about the fate of EROS in South Dakota
A preliminary budget request from President Donald Trump takes aim at a satellite program with a 50-year history whose data is housed just northeast of Sioux Falls, at a facility employing hundreds of people.
Trump's discretionary budget request for NASA would cut $1.1 billion in funding for Earth observation programs, including what the request describes as cuts to the 'gold-plated, two billion dollar Landsat Next' mission. The cut amounts to roughly half of the space agency's budget for Earth observation, which includes money for Landsat design.
Landsat Next is planned as the next generation of Landsat, whose nine iterations have created the longest continuously collected Earth observation record in history. The first satellite launched in 1972.
NASA builds and launches Landsat satellites. The U.S. Geological Survey (USGS) operates them and curates the data collected by them.
The USGS Earth Resources Observation and Science (EROS) Center near Sioux Falls has housed Landsat data since 1973, in addition to millions of images from other satellites and modern and historical aerial imagery, all of which is accessible at no cost to users. Landsat's free data is used to calibrate data from commercial satellites, contributing to what the USGS calculated last fall as a $25.6 billion return on public investment since the agency began freely sharing data in 2008.
The most recent satellite in the series, Landsat 9, entered low-earth orbit in 2021. Between that satellite and its near-identical predecessor, Landsat 8, the system gathers new imagery data of the entire Earth's surface — as well as imagery from spectral bands like infrared that are invisible to the naked eye and measurements of Earth surface temperatures — every eight days.
Landsat Next was set to launch around 2030, with improvements in resolution and speedier repeat image collection.
Trump's budget request would 'restructure' the Landsat Next mission 'while NASA studies more affordable ways to maintain the continuity of Landsat imagery, which is used by natural resource managers, States, and industry.'
The request also calls for the elimination of $562 million in USGS funding. The change 'eliminates programs that provide grants to universities, duplicate other Federal research programs and focus on social agendas (e.g., climate change) to instead focus on achieving dominance in energy and critical minerals,' Trump's budget request says.
The cut to USGS amounts to about a third of its $1.6 billion budget.
The budget request is separate from the federal government's efforts under Elon Musk's Department of Government Efficiency to pare down the federal workforce.
Probationary employees across multiple federal agencies were first dismissed in February, but many returned to the federal payroll and placed on paid administrative leave after legal challenges.
It's unclear how those moves to reduce the federal workforce have impacted the EROS Center.
Around 600 government employees and contractors work at the center, according to the latest figures posted on the USGS website, but the site including that figure hasn't changed since March 2023.
Emails from South Dakota Searchlight to USGS press contacts at EROS and in regional and national offices on the number of employees who've departed since Jan. 25 went unanswered.
The biggest thing you've never heard of: How EROS changed the world from a cornfield
Searchlight also asked about the potential impact of the USGS budget cut proposal to EROS science programs, and about how changes to the Landsat program could affect EROS.
A NASA spokesperson told South Dakota Searchlight that the agency would be in a better position to respond 'once we receive the President's full budget request in the coming weeks.'
U.S. Rep. Dusty Johnson, R-South Dakota, pointed out that presidential budget requests are 'aspirational' and 'rarely implemented as written.'
'Dusty will continue to be supportive of Landsat's efforts in Congress,' said a Johnson spokesperson.
The NASA budget has not emerged as a discussion point in budget reconciliation talks underway in Washington, D.C., on Trump's so-called 'big, beautiful bill.'
U.S. Sen. Mike Rounds, R-South Dakota, sounded similar notes in his response to questions about Landsat.
'The president's discretionary budget is just that — discretionary. It outlines the president's priorities and wish lists, but it will ultimately be our job in Congress to set the budget and appropriate federal dollars,' Rounds said in an emailed statement.
Representatives for Republican Senate Majority Leader John Thune of South Dakota did not return emails requesting comment on Landsat and EROS.
Republican South Dakota Gov. Larry Rhoden told Searchlight during a visit to Sioux Falls recently that he hadn't heard about requested cuts to the satellite program or to the USGS.
Even so, Rhoden said he trusts that an open relationship with the Trump administration on South Dakota's priorities will help preserve them through budget negotiations.
'They give you some wiggle room as far as what your priorities are, and so I'm kind of optimistic that they are tempering some of those decisions with common sense,' Rhoden said.
Trump's actions have had at least one public impact on EROS, though not an operational one.
EROS is home to a supercomputer whose processing power is shared across multiple arms of the Department of Interior. The system came to EROS with the name Denali, named after the tallest peak in the U.S.
Like the Alaska mountain after which the computer was named, the Denali system at EROS was renamed 'McKinley' after the issuance of a Trump executive order.
Denali has long been the mountain's name among Alaska's Indigenous Athabascans, but the federal government embraced the name given to it by a prospector for about 100 years. The prospector called it 'Mount McKinley,' after then-presidential candidate William McKinley.
President Barack Obama renamed it Denali in 2015, matching the name the surrounding national park had taken nearly 40 years earlier.
The order does not mention the USGS or supercomputers, but rather instructs the Department of Interior to 'update the Geographic Names Information System (GNIS) to reflect the renaming and reinstatement of Mount McKinley.'
The EROS supercomputer's name was changed based on the order, however.
'Pursuant to President Trump's Executive Order No. 14172, 'Restoring Names that Honor American Greatness,' this supercomputer has been renamed to McKinley,' a poster in the EROS visitor area now reads.

Astronauts launch to the space station after sidelined by Boeing's troubled Starliner
Zena Cardman, a biologist and polar explorer who should have launched last year, was yanked along with another NASA crewmate to make room for Starliner's star-crossed test pilots. 'I have no emotion but joy right now. That was absolutely transcendent. Ride of a lifetime,' Cardman, the flight commander, said after reaching orbit. The botched Starliner demo forced Butch Wilmore and Suni Williams to switch to SpaceX to get back from the space station more than nine months after departing on what should have been a weeklong trip. Get Starting Point A guide through the most important stories of the morning, delivered Monday through Friday. Enter Email Sign Up 'Every astronaut wants to be in space. None of us want to stay on the ground, but it's not about me,' Cardman said before her flight. Advertisement NASA's Mike Fincke — Cardman's co-pilot — was the backup for Wilmore and Williams on Starliner, making those three still the only ones certified to fly it. Fincke and Japan's Kimiya Yui, former military officers with previous spaceflight experience, were training for Starliner's second astronaut mission. With Starliner grounded until 2026, NASA switched the two to the latest SpaceX flight. 'Boy, it's great to be back in orbit again,' Fincke radioed. He last soared on NASA's next-to-last space shuttle flight in 2011. Advertisement Rounding out the crew is Russia's Oleg Platonov. The former fighter pilot was pulled a few years ago from the Russian Soyuz flight lineup because of an undisclosed health issue that he said has since been resolved. On hand for the first launch attempt on Thursday, NASA's new acting administrator, Transportation Secretary Sean Duffy, met with Roscosmos director general Dmitry Bakanov, an invited guest. The two discussed future collaboration, then left town after thick clouds forced a last-minute delay. 'What we learn on these missions is what's going to get us to the moon and then from the moon to Mars, which is I think the direction that NASA has to be,' Duffy said in a NASA interview. 'There's critical real estate on the moon. We want to claim that real estate for ourselves and our partners.' To save money in light of tight budgets, NASA is looking to increase its space station stays from six months to eight months, a move already adopted by Russia's space agency. SpaceX is close to certifying its Dragon capsules for longer flights, which means the newly launched crew could be up there until April. NASA is also considering smaller crews — three astronauts launching on SpaceX instead of the typical four — to cut costs. As for Starliner, NASA is leaning toward launching the next one with cargo before flying another crew. Engineers are still investigating the thruster failures and helium leaks that bedeviled Starliner following liftoff. Time is running out as NASA looks to abandon the aging space station by 2030. An air leak on the Russian side of the station remains unresolved after years of patching. Advertisement Engineering teams already are working on the plan for the space station's last days. NASA's Ken Bowersox said the US and Russia need to cooperate in order to steer the outpost into the Pacific with minimal risk to the public. It will take at least two years to get the space station low enough to where a SpaceX vehicle can provide the final shove. Thrusters on the Russian side of the station will help with control, but that means more fuel will have to be delivered by 2028. The latest timeline calls for SpaceX to launch the last mission for NASA — the deorbit vehicle — to the space station in 2029. Astronauts would remain on board until the last four to six months of the station's life to handle any breakdowns, with the empty outpost plunging into the Pacific by late 2030 or early 2031.

Russian and US space chiefs meet to discuss continued cooperation
MOSCOW — Russia's space chief has visited the United States to discuss plans for continued cooperation between Moscow and Washington on the International Space Station and lunar research with NASA's acting chief, the first such face-to-face meeting in more than seven years. Dmitry Bakanov, the director of the state space corporation Roscosmos, met Thursday with NASA's new acting administrator, Transportation Secretary Sean Duffy, on a visit to attend the planned launch of a U.S.-Japanese-Russian crew to the space station. The launch was delayed by weather until Friday, when it blasted off successfully. Roscosmos said Bakanov and Duffy discussed 'further work on the International Space Station, cooperation on lunar programs, joint exploration of deep space and continued cooperation on other space projects.' Once bitter rivals in the space race during the Cold War, Roscosmos and NASA cooperated on the space station and other projects. That relationship was beset with tensions after Moscow sent troops into Ukraine in 2022, but Washington and Moscow have continued to work together, with U.S. and Russian crews continuing to fly to the orbiting outpost on each country's spacecraft. Plans for broader cooperation, including possible Russian involvement in NASA's Artemis program of lunar research, have fallen apart. As Russia has become increasingly reliant on China for its energy exports and imports of key technology amid Western sanctions, Roscosmos has started cooperation with China on its prospective lunar mission. Speaking to Russian reporters after the talks with Duffy, Bakanov said that they agreed to keep working on keeping the space station in operation to the end of the decade. 'Our experts will now start working on those issues in details,' Bakanov said, praising Duffy for giving a green light for those contacts 'despite geopolitical tensions.' The Russian space chief added that he and Duffy will report the results of the meeting to Russian President Vladimir Putin and President Donald Trump to secure their blessing for potential space cooperation. 'In view of the difficult geopolitical situation, we will need to receive the necessary clearance from the leaders of our countries,' Bakanov said. He added he invited Duffy to visit Moscow and the Russia-leased Baikonur launch facility in Kazakhstan for the launch of another Russia-U.S. crew to the space station scheduled for November. 'I will put my efforts into keeping the channel of cooperation between Russia and the U.S. open, and I expect NASA to do the same,' Bakanov said.

Astronauts Head to Space Station as Clouds Stay Just Far Enough Away
SpaceX's latest mission for NASA launched four astronauts toward the International Space Station on Friday. An initial launch attempt on Thursday was thwarted in the last minute of the countdown by a threatening cloud above the launch site at NASA's Kennedy Space Center in Florida. On Friday, a U-shape formation of clouds encroached but stayed just far enough away for the launch to proceed. 'We got very lucky today, I would say,' Steve Stich, the manager of NASA's commercial crew program, said during a postlaunch news conference. The mission is known as Crew-11, because it is the 11th time that SpaceX, the rocket company run by Elon Musk, has taken astronauts to the International Space Station as part of the usual rotation of crew members living and working in orbit. Aboard the Crew Dragon spacecraft are Zena Cardman and Michael Fincke of NASA, Kimiya Yui of Japan and Oleg Platonov of Russia. Want all of The Times? Subscribe.
