An international space summit, co-chaired by France and Germany, took place on September 9 and 10 at the Grand Palais in Paris. The summit aimed to foster global collaboration in space as the domain faces growing militarization and the increasing influence of private companies. Experts at the event raised concerns about the accumulation of thousands of objects in orbit, which has risen sharply over the past decade. Christophe Bonnal, a space debris expert from the Academy of Air and Space, noted that the number of objects in orbit has increased tenfold since 2013, reaching approximately 15,000. He emphasized that the situation is not improving, as the number of satellite constellations continues to grow rapidly, with minimal regulatory oversight.
Bonnal explained that while international guidelines exist—such as those from the Interagency Debris Coordination Committee (IADC) and the International Organization for Standardization (ISO)—they are not being applied effectively. He pointed out that the current U.S. administration has relaxed restrictions on American satellite constellations, increasing the risk of collisions and potentially triggering a chain reaction known as the Kessler syndrome. This scenario involves a cascade of collisions between debris, creating even more space junk and making orbital paths increasingly dangerous.
The expert highlighted that debris orbiting between 700 and 1000 kilometers can collide and regenerate, creating hundreds or even tens of thousands of new pieces of debris. These objects can remain in orbit for centuries, traveling at speeds of up to 30,000 kilometers per hour, which increases the risk of collisions with operational satellites and spacecraft. Bonnal acknowledged that France is seen as a model for space regulation due to its 2008 space law, but he criticized China for conducting space operations that leave debris in critical orbital regions.
Efforts are underway to develop specialized spacecraft, sometimes called "space tugs" or "garbage trucks," to capture and remove large debris from orbit. However, these projects face significant challenges, particularly in capturing and retrieving heavy objects. Controlled deorbiting—where large objects are guided back to Earth and disposed of in the southern Pacific Ocean—is being promoted as a safer alternative. This method has been used for satellites like the European TV satellite, and similar plans are in place for the International Space Station (ISS), which is expected to be deorbited into the southern Pacific by 2031. However, Bonnal noted that few entities are currently implementing such measures effectively.
