Current Orbital Situation

The proliferation of satellites and debris in Earth's orbit has been on a steady rise. As per a report from the European Space Agency (ESA), approximately 15,760 satellites have been launched into space since the inception of the space age. Of these, around 10,550 remain in orbit, with 8,400 still operational. Concurrently, there are roughly 34,440 tracked debris objects, with an estimated 640 instances of fragmentation resulting from break-ups, explosions, collisions, or anomalous events. The heightened risk exposure for assets in space is evidenced by a significant surge in conjunctions or close approaches between space objects. In certain orbital paths, the incidence of conjunctions has escalated by a minimum factor of 5. The calculation of collision probability during close approaches hinges on various factors, including estimated miss distance, positional and trajectory uncertainties, and the physical dimensions of the objects involved.
