Rising Space Debris Threats and China's Spaceflight Advances

The article discusses the increasing risk of space debris hitting airplanes, highlighting the challenges in predicting re-entry of space junk, recent incidents like China's Long March 5B re-entry, and efforts to improve safety through better prediction models, international coordination, and standards, while reassuring that the probability of a collision remains very low.

SpainSat NG 2 Satellite Encounters Space Particle Impact, Activates Contingency Plans

A Spanish military communications satellite, SpainSat NG 2, launched in October 2024, was struck by a 'space particle' while maneuvering in orbit, potentially affecting its mission. The incident occurred at about 50,000 km altitude, possibly involving micrometeoroids or space weather effects, but not orbital debris. The satellite's operator, Indra Group, is analyzing the damage and has contingency plans, including potential replacement, which could take years. The satellite is part of a European secure communications network.

Innovative Solutions and Concerns in Satellite Pollution and End-of-Life Management

Researchers propose a shift from designing satellites to burn up upon reentry ('design for demise') to creating indestructible satellites ('design for non-demise') that survive reentry, aiming to reduce atmospheric pollution and protect the ozone layer, despite potential risks of debris falling to Earth.

Researchers Warn Moon's Patches Could Turn into Spacecraft Cemeteries

Researchers warn that the increasing number of lunar satellites will lead to the moon becoming a graveyard for defunct spacecraft, potentially damaging scientific sites and instruments. To manage this, experts suggest establishing designated impact zones for controlled crash-landing of old satellites, which could also provide seismic data about the moon's structure.

Urgent Warning: Solar Storms and the Rising Risk of Space Debris Collisions

A new metric called the CRASH Clock quantifies the risk of catastrophic satellite collisions, revealing that a severe event like a solar storm could cause a collision in less than three days, highlighting the urgent need to address space debris and satellite congestion, especially with the rapid increase in satellite constellations by companies like SpaceX.

Starlink and Chinese Satellites Nearly Collide Again, Raising Concerns

A near-miss occurred on December 12 when a Starlink satellite narrowly avoided colliding with a Chinese-launched satellite launched just 48 hours earlier, highlighting the lack of an international space traffic management system. With the increasing number of satellites from companies like SpaceX and Amazon, the risk of space debris and collisions is rising, potentially leading to catastrophic chain reactions and debris falling to Earth, emphasizing the urgent need for coordinated space traffic control.

Satellite Collision Risks Accelerate Amid Solar Storm Threats

A new study warns that a severe solar storm could trigger satellite collisions in Earth's orbit within days, especially in low Earth orbit where most satellites like SpaceX's Starlink operate, potentially leading to a cascade of debris and making space unusable. The risk is higher now than in 2018 due to increased satellite numbers, and future solar storms could cause significant disruptions if satellite operators are unprepared.
