Rising space launches and heat-resistant carbon-fiber materials are allowing larger debris to survive atmospheric reentry, increasing debris reaching Earth and prompting researchers and policymakers to pursue safer design approaches and tighter regulations to protect people and property.
ESA and JAXA signed an agreement to launch the Ramses mission to the near-Earth asteroid Apophis, with a planned 2028 launch and a 2029 rendezvous during its close Earth flyby at about 32,000 km. The mission aims to study how Apophis behaves under Earth's gravity and to collect data that could improve asteroid deflection and monitoring strategies, informing future planetary-defense efforts. ESA will lead spacecraft design and operations, JAXA will contribute lightweight solar arrays and an infrared imager, and ESA’s NEO Coordination Centre will refine orbital predictions ahead of the flyby. This collaboration showcases international partnership as a cornerstone of global space safety.”,
NASA plans the FM2 experiment to ignite four solid-fuel samples on the lunar surface under controlled, habitat-like conditions to study how flames behave in reduced gravity, with cameras and sensors to assess flame growth and spread. The goal is to refine safety standards for future lunar habitats, since flames can behave differently in lunar gravity and high-oxygen environments, and the late-2026 launch could influence material safety and emergency protocols for off-Earth bases.
NASA plans four solid-fuel burns inside small lunar habitats to test material flammability under partial lunar gravity, evaluating whether Earth-based standards like NASA-STD-6001B apply; measurements will use cameras, radiometers, and an oxygen sensor, with a late-2026 launch goal to inform fire safety for future Moon missions.
A new 'CRASH Clock' study warns that in a worst-case scenario, Earth-orbiting satellites could start colliding within less than three days, a significant decrease from previous estimates, driven by the rapid increase in satellite numbers and potential space weather events, raising concerns about space debris and the Kessler Syndrome.
SpaceX plans to lower around 4,400 Starlink satellites from 550 km to 480 km altitude in 2026 to enhance space safety, reduce collision risks, and address recent debris incidents, amid a significant increase in space object traffic and collision mitigation efforts.
SpaceX plans to lower the orbits of about 4,400 Starlink satellites from 550 km to 480 km by 2026 to enhance space safety, reduce collision risks, and improve performance, amid recent satellite anomalies and international concerns over space debris and security.
A SpaceX Starlink satellite experienced a mysterious anomaly, lost contact, and is tumbling back to Earth, creating debris; the cause is under investigation, highlighting increasing space traffic and collision risks.
A new study warns that the risk of catastrophic satellite collisions in Earth's orbit has increased significantly, with the 'CRASH Clock' now at just 2.8 days, indicating little time to prevent disaster from solar storms or satellite debris chain reactions, potentially leading to severe space and Earth-based consequences.
A new study warns that the increasing density of satellite mega-constellations in Low Earth Orbit creates a fragile system at risk of catastrophic collision, especially during solar storms, with potential for a rapid cascade of debris and loss of space access within days if control is lost. The paper emphasizes the urgent need for better management and risk assessment to prevent a future space debris catastrophe.
Starlink and Chinese satellites nearly collided last week, highlighting ongoing concerns about space safety and satellite management. The incident underscores the importance of tracking and coordinating satellite movements to prevent collisions in increasingly crowded orbits.
Recent incidents involving stranded astronauts on China's Tiangong space station and the Boeing Starliner highlight the urgent need for a dedicated space rescue capability, prompting experts to call for standardized procedures and affordable organizational solutions to ensure astronaut safety in emergencies.
The Chinese crew of Shenzhou-20, originally set to return to Earth, is stranded in orbit due to a suspected impact from untracked space debris, highlighting growing concerns over space debris risks and the safety protocols in place for human spaceflight. The delay allows for inspection and safety measures, with the crew continuing their mission aboard the Tiangong station.
China has delayed the return of the Shenzhou-20 spacecraft due to suspected debris impact damage, with no new return date set, raising safety concerns similar to past spaceflight incidents like the Columbia disaster and NASA's recent spacecraft issues.
The European Space Agency (ESA) has introduced a Space Environment Health Index to quantify the impact of human activities on Earth's orbital environment, highlighting that current space debris levels are four times higher than the sustainability threshold and emphasizing the need for stronger mitigation efforts to ensure long-term space sustainability.
