However, since the establishment of NASA's Orbital Debris Program in 1979, the term also encompasses human-made debris, including defunct satellites, spent rocket stages, and fragments from their deterioration or collisions. Quantity of Space Debris As of December 2016, five major satellite collisions have contributed significantly to space debris. According to the European Space Agency in 2018: Approximately 29,000 objects larger than 10 cm are in orbit. Around 750,000 objects measure between 1cm to 10 cm. An estimated 166 million objects range between 1mm to 1cm in size. Over 170 million fragments smaller than 1cm. Around 670,000 fragments measuring 1–10 cm. Approximately 29,000 larger pieces orbiting Earth. Artificial debris in orbit includes broken satellites, roc...

However, one thing is clear: space plays an essential role in our daily lives. Looking back to 1957, approximately 8,378 satellites have been launched into space. Of these, around 4,987 satellites remain in orbit, operated by more than 40 countries worldwide. Safeguarding space and ensuring its peaceful use is a legitimate concern for every nation, whether they are space-capable or not. Space exploration significantly drives technological development, which is important for human advancement. Communication satellites provide access to remote and disconnected regions, bridging the digital divide. Space technology empowers us to monitor the pace and impact of global warming, essential for guiding mitigation efforts. Satellites also contribute to weather forecasting, disaster management, telecommunication...
