Artemis Era Raises Safety Concerns as Lunar Orbit Nears Capacity, New Study Finds
As lunar exploration surges, scientists warn that the Moon’s limited stable orbits are growing crowded. Georgia Tech simulations suggest that with about 50 satellites, each may need several collision-avoidance maneuvers per year. Even now, orbiters like Chandrayaan-2 require frequent course corrections. With Artemis and private missions incoming,...

China and NASA Coordinate to Avoid Satellite Collision for the First Time
China’s CNSA made history by alerting NASA to a possible satellite collision—marking the first instance of Beijing warning Washington in orbit. With Earth’s orbits growing crowded from megaconstellations like Starlink and Guowang, the event signals a new phase of cooperation in global space traffic control and shared responsibility for orbita...

Rising Satellite Traffic in Low Earth Orbit Sparks Collision Risk Concerns
A new study in Acta Astronautica warns that Low Earth Orbit is becoming dangerously congested. Since 2019, the number of satellites performing more than ten collision-avoidance maneuvers per month has risen sevenfold. With nearly 25,000 tracked objects and more launches planned, scientists fear a chain-reaction risk and call for stronger global coo...

Cosmic Visitor: 4.56-Billion-Year-Old Meteorite Strikes into Georgia Home
On June 26, 2025, a dazzling daytime fireball streaked over Georgia, captured by satellites and witnessed across multiple states. A surviving fragment smashed through the roof of a McDonough home, denting the wooden floor 14 feet below. Scientists at the University of Georgia analyzed about 23 grams of this ancient rock, determining it to be a 4.56...

Iran’s Folded Rocks Reveal Ancient Tectonic Power at Asia-Europe Boundary
Iran’s Zagros Mountains showcase tightly folded rock layers caused by the slow-motion collision of the Arabian and Eurasian plates. Visible from space, these dramatic geological structures reveal the raw power of continental tectonics and provide scientists with valuable insights into mountain formation, seismic activity, and Earth’s ongoing st...

Rocket Lab Delays IoT Satellite Launch to Ensure Safe Trajectory in Space
Rocket Lab has postponed its "IOT 4 You and Me" mission to avoid potential collisions with satellites and the International Space Station. This mission, set to deploy five IoT satellites, marks Rocket Lab's first launch of 2025. The company is taking extra precautions to monitor space traffic and ensure the rocket follows a safe trajectory. The sat...

ISS Successfully Executes Collision Avoidance Maneuver Amid Rising Space Junk Threat
The International Space Station (ISS) conducted its 39th collision avoidance maneuver to evade space debris from a 2015 satellite breakup. The adjustment in orbit prevented a potential close encounter within 2.5 miles of the ISS. Experts attribute increasing debris risks to factors such as satellite fragmentation events and solar activity. Measures...

Skynet-1A Satellite’s Unexplained Orbit Shift Raises Questions About Command History
Launched in 1969, the UK's oldest satellite, Skynet-1A, has moved significantly from its original position. Experts believe this was due to a deliberate command in the 1970s. The satellite now orbits over the Americas, near active satellite traffic, raising risks of collisions. Limited records exist regarding its control history, with suggestions o...

NASA Shows Giant Debris Cloud Formed by Collision of Celestial Bodies
Most rocky planets and satellites, including our Earth and the Moon, are formed or shaped by massive collisions among celestial bodies early in the solar system. When these objects smash together, they could either accumulate more material and increase their size or they can break apart into multiple smaller bodies.
