Also called space debris, space junk is comprised of non-operational satellites and other human-made objects that continue to hurtle around Earth's orbit long after they served their purpose.

New data analysis indicates that NASA and its partners could have more cost-effective methods for dealing with the growing issue of orbital debris than previously thought. A new report from NASA's ...

In low-earth orbit, objects can collide at around 23,000 miles an hour, enough for even the tiniest debris to crack the windows on the International Space Station.

Cleaning up space debris seems rather unnecessary in this perspective, except that even the tiniest chunk travels at orbital velocities of multiple kilometers per second with kinetic energy to spare.

It takes “several years” for debris to return at altitudes of 373 miles (600 kilometers) or less, but centuries for “orbital decay” to occur at 497 miles (800 kilometers).

The Federal Communications Commission plans to streamline its space activities to meet fast-growing space safety needs. The fast-growing space debris issue is top of mind at a new space-focused ...

Like satellites, LEO debris whizzes around the planet at 17,000 miles an hour (27,400 kilometers an hour) or more. The orbits of these objects differ in direction, orbital plane, and speed ...

Orbital debris, or space junk, “consists of human-made objects orbiting Earth that no longer serve a purpose, including mission-related and fragmentation debris, nonfunctional spacecraft and ...

WASHINGTON, Sept. 13, 2022 /PRNewswire/ -- As part of NASA's efforts to address orbital debris, the agency is funding research proposals from three university-based teams over the next year to ...

Mp42 satellite's selfie above the South Pole revealed damage sustained by orbital debris. Kongsberg Nanoavionics Earth’s orbit is getting really crowded, with hoards of new satellites being ...
