NASA astronauts sheltered inside their SpaceX Dragon capsule last week while Russian cosmonauts worked to repair a worsening leak aboard the International Space Station, a fresh reminder that the 25-year-old orbiting laboratory is running out of time. The agency's answer is a controlled demolition worth nearly $1 billion, and the clock is already ticking.
The step-by-step plan, detailed by the Daily Mail, calls for NASA to let the 450-tonne station begin its slow descent from orbit in 2028, with a final fiery crash into a remote stretch of the Pacific Ocean in 2031. Between now and then, a modified SpaceX Dragon capsule, carrying six times the propellant of current spacecraft, will dock with the station and deliver the push that sends it to its grave.
The price tag: just under $1 billion. The contractor: Elon Musk's SpaceX, which won the NASA contract in 2024. The target: a patch of ocean called Point Nemo, the most remote spot on the planet, sometimes called the "Spaceship Graveyard" because dozens of defunct spacecraft already litter its floor.
The ISS has been permanently crewed since November 2000. It weighs roughly 450,000 kilograms, about the same as 280 family cars, stretches 356 feet long, and hurtles around the Earth 16 times a day at 17,500 miles per hour. Seven astronauts live aboard at any given time, with a maximum capacity of 13. Some 244 individuals from 19 countries have visited. Eight private citizens have paid up to $50 million apiece for the privilege.
It is also a $100 billion science and engineering laboratory that costs NASA about $3 billion a year to maintain.
Last week's emergency underscored the fragility of the aging station. NASA astronauts were ordered to prepare for evacuation while cosmonauts attempted repairs. No escape flights were ultimately necessary, but the incident was a stark signal: the ISS is not getting younger, and astronauts sheltering in a Dragon capsule while colleagues cut into the station's hull is not a routine day at the office.
NASA's own 2024 assessment laid out the logic in plain terms. The agency concluded that controlled re-entry is required because the ISS is so large that an uncontrolled breakup would scatter massive debris across an unpredictable footprint, posing what NASA called "a significant risk to the public worldwide."
That assessment also stressed a quieter point: keeping the station well-maintained remains the safest approach while NASA simultaneously plans for the end of its life.
Ryan Landon, director of operations at NASA's Johnson Space Center, told attendees at the ASCEND 2026 aerospace conference that the ISS would begin its descent sometime in 2028. The station currently orbits at about 250 miles above Earth. During the initial phase, it will be allowed to gradually drop to 200 miles. NASA says research and on-board activities will continue as normal during this period.
Roughly 18 months before the planned 2031 crash, the modified Dragon capsule will dock with the station. That vehicle will need to produce three to four times as much power as current SpaceX spacecraft and carry enough propellant, about nine tonnes, to change the ISS's speed by approximately 127 miles per hour.
Dana Weigel, NASA's ISS manager, described the sequence at a 2024 press conference:
"At the right time, it will perform a complex series of actions... over several days to deorbit the space station. First, the deorbit vehicle will perform orbit shaping burns to put the station in a low elliptical orbit, and then, eventually, it will perform a final re-entry burn."
The last human crew will depart in 2029, taking anything of historical importance they can carry. NASA officials say the final cargo capsule will leave around mid-2029, ahead of the official end of operations in 2030. Once the station drops below 175 miles, it crosses the point of no return.
At around 150 miles, the ISS hits thicker atmosphere. Most of the structure will burn up. But NASA estimates that 40 to 100 tonnes of denser materials could survive re-entry and reach the surface, aimed, if all goes to plan, at Point Nemo.
Dr. James Beck, a space debris expert and director of UK-based consultancy Belstead Research, told the Daily Mail that survival of debris is not a possibility but a certainty.
"It is certain that parts will reach the surface of the Earth, and most likely quite a lot of parts. The open question is how many, and whether there can be sufficient control over where this occurs."
Beck noted an internationally agreed casualty-risk limit of one in 10,000 for any re-entry, a threshold typically reached once a spacecraft has a mass of around 500 to 1,000 kilograms. The ISS dwarfs that figure by orders of magnitude. Beck's assessment was blunt: "It should be expected that a few hundred objects which could cause casualties on the ground would be produced."
NASA has been through a version of this before. In 1979, the agency's 75-tonne Skylab space station tore itself apart during a planned re-entry and scattered debris over parts of Western Australia. The ISS is six times heavier than Skylab. The stakes of getting the trajectory wrong are correspondingly larger.
The agency is betting that precision burns, modern guidance, and a remote ocean target will keep people safe. But Beck's open question, whether sufficient control is achievable, hangs over the entire enterprise. The gap between NASA's confidence and an independent expert's caution is worth watching as 2028 approaches.
NASA is not abandoning human spaceflight in low Earth orbit. The agency is working with ESA, Japan's JAXA, and the Canadian Space Agency to build a station in orbit around the moon, part of the broader Artemis program that has already sent astronauts toward the moon for the first time in decades.
Meanwhile, private firm Axiom Space plans to send its own modules for commercial use to the ISS around the same time Russia is developing its own platform. The transition from a government-run orbiting laboratory to a mix of commercial and international successors is already underway.
But transitions cost money, and NASA's track record on cost and schedule is not unblemished. The agency recently ended its MAVEN Mars mission after six months of silence, a reminder that even well-funded programs can go dark without warning. And the broader space-launch landscape has seen its own setbacks, including Blue Origin's New Glenn rocket explosion at Cape Canaveral, which raised hard questions about NASA's dependence on commercial partners for its most ambitious plans.
The nearly $1 billion SpaceX deorbit contract is, in one sense, a bargain compared to the $100 billion invested in the station over its lifetime. In another sense, it is a billion taxpayer dollars spent to destroy something taxpayers already paid to build and maintain, at $3 billion a year, for a quarter century.
The plan is methodical. The engineering is serious. The risks are real and acknowledged. None of that means Congress or the public should simply trust the timeline and look away.
The ISS leak that forced astronauts into emergency shelter last week was not a hypothetical. It was a real-world signal that the station's condition is deteriorating. NASA's 2024 assessment said maintenance remains the safest approach while planning proceeds, but "well maintained" is a moving target on a structure that has been in continuous service for more than 25 years in one of the harshest environments imaginable.
Open questions remain. What exactly is the status of the leak? What is the precise re-entry footprint at Point Nemo? What contingency exists if the modified Dragon vehicle underperforms or the station's orbit decays faster than expected? The successful Artemis II splashdown showed NASA can still execute precision recoveries. Whether the agency can guide 450 tonnes of aging hardware into a controlled Pacific grave is a different order of challenge.
Taxpayers deserve clear answers and regular public updates, not a billion-dollar program that disappears into the bureaucracy until something goes wrong at 17,500 miles per hour.
When the government spends a billion dollars to destroy something, the least it owes the people who paid for it is a window seat.
