Commercializing space debris removal may follow the commercialization of launches

A financial analysis of space trash cleanup strategies identified long-term benefits

Despite significant initial costs, a NASA report found that removing small debris would provide savings from preventing mission-ending damage, which would offset expenses within a decade. Financial benefits would also come from using less fuel for maneuvers to avoid collisions with debris.

By 2028, a space trash-avoiding maneuver is expected to occur every 18 seconds

As the number of active Starlink satellites increases, greater efforts will be required to keep low Earth orbit free of debris, sparking a new technological space race. NASA has found that using lasers to manage small and medium debris could save up to $9B over 30 years.

Scientists have proposed using lasers to push space trash into Earth's atmosphere

Such projects would allow most debris to burn up and no longer pose a risk to active satellites, telescopes, and astronauts on space stations. Enacting these plans would require substantial investments from private and governmental space agencies and overcoming international laws that prevent the removal of another country's space equipment.

Space trash could be cleaned up using a giant inflatable bag

California-based TransAstra has developed and tested a device called Capture Bag, intended to catch anything from small rocks to house-sized boulders. The company claims its system could also be adapted for asteroid capture and mining.

In 2023, there were nearly as many payloads in LOE as trackable pieces of debris

In 2021, the European Space Agency estimated that more than 130 million space debris objects larger than 1 millimeter were in low Earth orbit, though only about 22,000 were being tracked. As of late 2025, the tracked total exceeds 49,000.

When retired, the International Space Station will undergo a controlled de-orbit

With plans to transition low-Earth orbit operations to private entities, the ISS is expected to be retired by 2030, using a SpaceX de-orbit vehicle. Although reentry will burn up most hardware, NASA intends for any surviving debris to fall into an uninhabited ocean area.

Spacecraft remnants and human waste left behind on the moon add to the trash in space

As more countries reach the moon with successful probe landings and unsuccessful crashes, more materials are left behind, adding to the amount of trash that needs to be retrieved. A United Nations treaty declared the moon a common heritage of humanity, exempting any one country from exclusive responsibility for cleanup.

Billionaires are racing to space to control future markets

Although different companies have described focuses ranging from luxury tourism to Martian space colonies, all are building infrastructure to capitalize on the shift away from government-only control and betting big on reusability and scale. By securing public contracts and subsidies, they aim to develop strategic partnerships toward dominance in low Earth orbit.

Find out how decommissioned oil rigs can be repurposed into artificial reefs

A 2014 paper analyzing drilling structures found many had become nursery habitats for fish, corals, sponges, and other invertebrates in the decades since their installation. Oil companies responsible for bringing these rigs to shore to salvage them can more affordably transport only the oil rig's deck on a barge, leaving the remaining rig to maintain the established biodiversity.

Space archaeology studies space trash in the context of heritage and social meaning

Some orbiting objects, such as Elon Musk's Tesla, have symbolic or historical importance, despite being functionally worthless. The oldest human-made object in Earth's orbit is Vanguard 1, a grapefruit-sized satellite launched in 1958. The strangest may be an experimental, inflatable space station containing live cockroaches.

Metal wreckage found in a Canadian farm turned out to be SpaceX spacecraft debris

The pieces of the wreck included a 36-kilogram aluminum spear more than 2 meters long, and its origins were confirmed by satellite tracker Jonathan McDowell. No government acknowledged or took accountability for the space trash, which SpaceX later quietly retrieved.

The reusability of Falcon 9's first stage rocket has slashed launch costs

Unlike older rockets left to sink in the ocean, the first stage was designed to steer itself back for a controlled landing on a sea-based barge. Refurbishment of these components are half the cost of building new.

In 2022, a piece of Challenger was discovered on the ocean floor

While searching for World War II wreckage near Cape Canaveral, Florida, for a documentary, divers discovered debris on the seafloor that NASA later confirmed to be a piece of Space Shuttle Challenger wreckage. The piece is at least 15-by-15 feet in size and partially buried under sand.

Space tourism opportunities have been explored since the end of the Apollo era

In the 1970s, Rockwell International, a NASA contractor, and others investigated manufacturing passenger modules that could fit into the Space Shuttle's payload bay. NASA also opened spaceflights to nongovernment professionals, but many such programs were ended after the Challenger disaster, which killed the first Teacher in Space participant.

Research has shown that bioengineered algae can help remove microplastics

Scientists at the University of Missouri found that, like microplastics, some algae are particularly hydrophobic—they repel water—and that both can clump together to form a microplastic-algae sludge, which can then be collected to remove microplastics from water. Researchers believe this algae provides a scalable solution for microplastic removal that can be employed in wastewater treatment processes.

The European Space Agency placed a lander on the surface of a comet in 2014

Launched in 2004, the Rosetta spacecraft performed three flybys of Earth and one of Mars as gravitational slingshots to gain the necessary velocity to successfully place the Philae lander module on comet 67P/Churyumov-Gerasimenko. Philae achieved a soft landing only after bouncing twice from failed deployments of its anchoring harpoons.

Comparing bioremediation with other treatment techniques, at three levels of complexity

Physical manipulation, such as collecting and moving contaminated material to a landfill, or chemical applications, which use strong, expensive substances and produce harmful byproducts, can be costly. While bioremediation leverages naturally occurring degradation processes that can be augmented without disrupting impacted ecosystems, these processes may be less effective in environments that bioremediation organisms are not adapted to.

A 1987 garbage barge that no state would accept accidentally sparked the US recycling movement

In the 1980s, an Alabama businessman loaded 3,168 tons of mafia-controlled New York trash onto a barge. It was rejected by six states and three countries, sparking a media frenzy. This event helped convince Americans that they were running out of landfill space, giving rise to curbside recycling.

Fiberglass and epoxy resin on blades complicate the recycling of wind turbines

Between 85 and 95% of a turbine's materials—except for the blades—can be recycled. Blades have been left in landfills when not repurposed into playgrounds and sheds, but new processes may allow them to be made into pellets for injection plastics and concrete.

The US-led global debt settlement market is expected to expand from $4.8B in 2024 to $7.2B by 2032

While debt settlement companies aren't technically allowed to charge fees until after lowering a consumer's debt, a loophole in the Telemarketing Sales Rule (a mix of federal and state laws) gives predatory firms the opportunity to exploit consumers.
