A presumed discovery of a gamma-ray burst from the oldest known galaxy in the universe was in fact a reflection of sunlight from a spent rocket stage in Earth's orbit, a new paper found.
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.
SpaceX's Starlink satellites are involved in about 1,600 close encounters between two spacecraft in low Earth orbit every week, according to available data. That’s about 50% of all such incidents.
A tiny cubesat called AuroraSat-1 will launch atop a Rocket Lab Electron booster in the fourth quarter of this year to demonstrate de-orbiting tech for small spacecraft.
A Malaysian satellite will settle into a graveyard orbit following a mysterious "anomaly" that struck it down in orbit.
The growing problem of space junk poses a risk to future space missions, but the solution isn't going to be easy.
Some astronomers suggest setting up a "SatHub" to address the growing threat that satellite megaconstellations pose to the night sky — but funding and support are necessary to make it happen.
U.K. rocket start-up Skyrora wants to collect the remains of the iconic British satellite Prospero from low Earth orbit and bring it to Earth to be displayed in a museum.
The Russian Progress MS-17 cargo ship, which launched toward the International Space Station on Tuesday (June 29), will come dangerously close to a Starlink satellite and a Falcon 9 rocket fragment.
Satellite parts that melt away during reentry reduce the risk of space debris impacts on Earth, a new video demonstrates.
New spacecraft sustainability rating will evaluate satellite missions based on responsible design with respect to protecting the orbital environment from the proliferation of space debris.
The western world's most advanced economies have agreed to take action against space debris at the G-7 Leaders' Summit in Cornwall, U.K.
A piece of space junk smacked into the robotic arm on the International Space Station, but near-term operations should not be affected.
Space junk removal company Astroscale hopes to start commercially removing dead satellites from orbit in the next three years.
Recent events serve as a timely reminder for the Biden Administration that securing the safety of space infrastructure is critical to their broader economic and national security goals.
The European Space Agency announced plans to launch a space debris removal mission in 2025 with the help of a Swiss start-up called ClearSpace.
After a huge Chinese rocket plummeted apparently into the ocean, NASA's new administrator condemned the country's use of launch technology that makes uncontrolled reentries from orbit.
The 23-ton core stage of a Chinese Long March 5B booster crashed back to Earth Saturday night (May 8), ending 10 controversial days aloft that captured the attention of the world.
