This NASA astronaut manages to make vacuuming look kinda cool
NASA astronaut Jonny Kim has just shared a video showing how they use a vacuum cleaner in space.
How do we clean in space? Similar to how we clean on Earth, but weightlessness has some extra challenges. pic.twitter.com/MOLXm3P7k6 — Jonny Kim (@JonnyKimUSA) July 11, 2025
Thanks to microgravity, there's no lifting or pulling (or possibly pushing) a machine. Instead, as Kim demonstrates in his video, you just clip the cleaner to your pants before floating off around the station to perform the task in hand. But that same microgravity means that the dust doesn't settle anywhere, so what then? Kim explains the process.

The American astronaut, who arrived at the station in April on his first orbital mission, says they clean the station using a 'pretty standard vacuum cleaner that you'd find on Earth,' but notes that the particles just float around in the weightless conditions.
'Luckily, we have an environmental control system that's got fans and diffusers and HEPA filters and so most of the dust tends to collect in these areas,' Kim explains. It means that instead of looking like a goof and vacuuming the air, all you do is run the vacuum over the filters and other devices to suck up the trapped dust.
Responding to a comment to his post asking why he's using a mains-connected vacuum and not a battery-powered one, Kim says that while cordless vacuums are available on the ISS, the rechargeable lithium-ion batteries don't last long enough to clean the entire facility.
'The International Space Station is not just a place where we conduct research on behalf of institutions across the world, but it's also our home for long periods of time,' Kim says. 'And like any home, you have to keep it clean and tidy, so we distribute these chores across crew members and one of these chores is vacuuming.'

Interlune will team up with Astrolab to send a camera to the moon for helium-3 survey
An artist's conception shows Astrolab's FLIP rover on the moon. Interlune plans to put a helium-hunting multispectral camera on the rover. (Astrolab Illustration) Seattle-based Interlune says it's struck a deal with California-based Astrolab to send a multispectral camera to the moon to estimate how much helium-3 is present in lunar soil. Interlune's camera will be one of the payloads aboard Astrolab's FLEX Lunar Innovation Platform rover, or FLIP for short. The FLIP rover is scheduled to take a piggyback ride to the moon's south polar region aboard Astrobotics' Griffin lander as soon as late 2025. The mission will mark Interlune's first off-Earth step in its campaign to identify and extract helium-3 from the moon and return it to Earth. Helium-3 can be used for applications ranging from quantum computing to security screening to fusion energy production. But it's rare on Earth: Interlune has pegged the commercial price of helium-3 at as much as $20 million per kilogram. Interlune is betting that lunar helium-3, which is produced when charged particles from the sun hit moon dirt, will become a cheaper source — and a source of revenue for the startup. The multispectral camera that Interlune has developed in partnership with NASA's Ames Research Center will be used to estimate helium-3 quantities and concentration around Griffin's landing site, without having to bring samples back to Earth. 'This is our first lunar mission and a seminal milestone toward being the first company to harvest natural resources from space,' Interlune's co-founder and CEO, Rob Meyerson, said today in a news release. 'Astrolab's ability to provide reliable mobility on the moon to partners like Interlune is the quintessential example of the collaboration and innovation building the lunar economy.' Astrolab's founder and CEO, Jaret Matthews, said his company was 'thrilled to be carrying Interlune's multispectral camera to the moon.' 'This is exactly the kind of mission we built Astrolab for — delivering breakthrough science to the lunar surface,' Matthews said. Interlune was founded in 2020 and raised $18 million in seed capital last year. In May, the startup announced that the U.S. Department of Energy and Maybell Quantum Industries would be among its first customers. At the time that announcement was made, Interlune said it would start delivering helium-3 in 2029.

Trump Administration Moves to Destroy Satellite That Monitors Greenhouse Gases
The Trump Administration's budget proposal for Fiscal Year 2026 would take an axe to NASA science. Two satellite missions on the chopping block have provided climate scientists, oil and gas companies, and farmers with critical atmospheric carbon data for years. The Orbiting Carbon Observatories are a pair of instruments that map atmospheric carbon on a global scale. NASA launched the OCO-2 in 2014 and mounted the OCO-3 on the International Space Station in 2019. Trump's budget proposal threatens both missions, but the standalone OCO-2 would be completely destroyed during its fiery descent through Earth's atmosphere. Though the budget has yet to pass, NPR reports that NASA scientists working on the OCO missions are already making 'Phase F' plans—essentially laying out options for termination. David Crisp, a retired NASA scientist who designed the satellites and managed the missions until 2022, told NPR that the NASA employees making those plans have reached out to tap his expertise. 'They were asking me very sharp questions,' Crisp said. 'The only thing that would have motivated those questions was [that] somebody told them to come up with a termination plan.' Three other academic scientists and two current NASA employees—all of whom requested anonymity—also confirmed to NPR that the agency is planning to terminate the missions. Congress has already funded both satellites through the end of fiscal year 2025, NPR reports. It could still choose to extend their funding through 2026, but it remains to be seen. In July, congressional Democrats did warn acting NASA administrator Sean Duffy not to terminate missions that Congress has funded—a sign that they may attempt to save the OCOs. Decommissioning these satellites would mark a significant scientific loss. The OCO-2 and OCO-3 sniff out atmospheric carbon dioxide using spectrometers to detect wavelengths of light absorbed by CO2 molecules. NASA designed them to improve monitoring of human-driven carbon emissions and variations in the natural carbon cycle, and they've certainly done a good job of this. OCO-2 data have helped scientists quantify how natural carbon sinks such as forests and oceans offset carbon dioxide emissions and how carbon sinks can become carbon emitters through drought, deforestation, or wildfires, according to NASA's Jet Propulsion Laboratory. This instrument has also provided valuable insights into urban carbon dioxide emissions and contributed data that supported the Paris Agreement. That's not all. Shortly after launching the satellite, NASA realized it could also measure plant growth, according to JPL. It does this by detecting the 'glow' plants emit during photosynthesis. When plants absorb sunlight to convert carbon dioxide and water into energy, their chlorophyll—a light-absorbing pigment—leaks some unused photons, JPL explains. This produces a faint glow called solar-induced fluorescence, and OCO-2 can spot it. This data helps farmers and agricultural scientists estimate crop productivity, monitor drought, and more. If Trump's budget passes, it will mean the end of the OCO-2, but there is hope for the OCO-3. NASA is seeking partnerships with institutions and companies willing to take over the cost of maintaining this ISS instrument. For now, like many of America's climate and environmental science programs, the future of both Earth-observing satellites hangs in the balance.
