NASA's Van Allen Probe A, a 600kg satellite, is set to re-enter Earth's atmosphere on Tuesday evening, with minimal risk of debris impact. Learn more about its mission and potential effects.

New research examines how smaller satellites in lower orbits could reduce collision risks and debris generation while maintaining high-resolution Earth observation capabilities.

Earth is surrounded by human-made debris that orbits our planet. The problem is worsening every year, and 2025 was no different. Space debris experts say nearly 130 million pieces of orbital junk are zipping around our planet: high-speed leftovers from ...

One person's trash is another person's treasure, unless, of course, you're talking about space debris, since it's too tough to acquire without a shuttle or a spaceship. That's a shame because space has a huge trash problem and it got even worse in 2024 ...

Space is no longer the final frontier it once seemed. Today, our planet's orbit resembles a cosmic junkyard where millions of debris pieces hurtle at devastating speeds, turning what should be humanity's greatest achievement into a constant target practice.

A surge in satellite constellations, the astronomers warn, would also further obscure observations of deep space. “For scientists, observing the deaths of stars and searching for new planets would become much harder,” they wrote. “Stargazing, astrotourism and cultural astronomy would similarly be disrupted worldwide.”

Anduril Industries said it plans to acquire ExoAnalytic Solutions, a company that operates one of the world’s largest commercial networks of telescopes used to track satellites and space debris, in a move that expands the defense technology firm’s push into national-security space programs.

Space: The final frontier is fraught with danger... and ever since we started launching things into orbit, that danger has often been of our own doing. As Dr. Nilton Renno at the University of Michigan explains it, a lot of space junk is moving at “the ...

Since 1971, space agencies have crashed retired spacecraft at Point Nemo, raising concerns about ocean debris and the ISS retirement.

A University of Alaska Fairbanks scientist is participating in a U.S. government effort to design a satellite and instruments capable of detecting space debris as small as 1 centimeter, less than one-half inch. Debris that small, which cannot currently be ...
