The increasing number of rockets launched into space is creating a growing problem: orbital debris. This debris poses a significant risk to satellites, spacecraft, and even commercial air travel.
The escalating number of rockets launched into space since the dawn of the Space Age has resulted in a growing concern: orbital debris . Over 6,740 rockets have been sent to space in the past 60 years, leaving behind an estimated 56,450 objects in orbit. While 36,860 of these objects are regularly tracked and maintained, the remaining 19,590 represent a significant hazard. This includes defunct satellites, spent rocket stages, and debris from propellant explosions and orbital collisions.
This issue has dire consequences, potentially triggering a cascade effect known as the Kessler Syndrome. This phenomenon occurs when collisions between debris create more debris, leading to a chain reaction that threatens the functionality of satellites, spacecraft, and future space exploration endeavors. The United States and China lead the way in launching rockets, and with the rate of breakups currently at 10 to 11 per year, the number of debris objects in orbit is projected to continue rising.The impact of this growing debris field extends beyond satellites, posing a risk to commercial air travel. According to a study by a team from the University of British Columbia (UBC), there is a 1 in 4 chance each year that debris falling to Earth will enter busy airspace. While the probability of debris hitting an aircraft is low (1 in 430,000), the UBC team's research highlights the potential for significant disruptions to commercial flights and the associated costs. Recent incidents, such as the explosion of a SpaceX Starship prototype on January 16th, have underscored the challenges of managing uncontrolled debris re-entry.The explosion forced the closure of airspace, causing flight diversions and delays. This event serves as a stark reminder of the urgent need for solutions to mitigate the risks posed by orbital debris. One potential solution is to design rockets to re-enter the Earth's atmosphere in a controlled manner, ensuring they crash into remote ocean areas away from populated regions and air traffic corridors. However, this requires collective international action and a commitment from all spacefaring nations and companies to adopt safer launch practices
