Since the launch of Sputnik 1 in 1957, the lower orbit around the Earth has become an increasingly congested environment.
The amount of trash in Earth orbit, from spent rocket stages, broken satellites and micrometeoroids, is growing. Scientists are working on methods to combat the threat of space junk and orbital debris collisions.
The Russian startup StartRocket is developing a "Foam Debris Catcher," a small, autonomous satellite that would snag and de-orbit space debris using sticky polymer foam.
Scientists aren't sure if space junk or a meteor caused a brilliant blue fireball seen across Western Australia.
Around the planet, a loosely knit but closely woven band of amateurs monitor the whereabouts of satellites — be they secretive spacecraft, rocket stages, orbital debris or lost space probes.
The ever-growing number of satellites in space prompted calls for change at a House hearing, although how this will be legislated is still under consideration.
One of the most pressing problems when it comes to keeping our planet safe from space threats is data, which sounds so simple to address. It's not.
In low Earth orbit's growing "space junkyard," new technologies could reduce the risk of collisions.
Satellite operators, and everyone else who wants a safe and sustainable space environment, dodged a bullet Wednesday evening (Jan. 29).
The potential (but unlikely) collision of two old satellites will be visible in the eastern U.S. today (Jan. 29) at at 6:39 p.m. EST. Here's how to see it.
The odds of a space-junk crash Wednesday evening (Jan.29) aren't as slim as we had thought, it turns out.
Let's hope that today's space-junk encounter is just a near miss as predicted, because a smashup would be pretty messy.
The ESA has announced a mission to launch a four-armed robot to grab a single piece of space junk and drag it into the atmosphere.
One person's space trash is another's space treasure — and that's definitely true for Alice Gorman, an archaeologist specializing in the detritus of spaceflight.
We can minimize the chances of a catastrophic cascade of collisions if satellite designers and operators follow a few simple rules, according to the Space Safety Coalition.
New infrared cameras and gel-based thrusters just might help future satellites dodge space debris, a new study finds.
The episode "Lines We Cross" ends with an old Soviet satellite crashing to Earth, sparking a new plot point for the show. But how realistic is it? We asked a scientist.
There was a 5.6% chance that Bigelow Aerospace's Genesis II experimental habitat and Russia's defunct Cosmos 1300 satellite would collide early this morning (Sept. 18). But it didn't happen.
