Historical and Cultural Survey of the Human Activities in Earth's Orbit and Beyond Through the Lens of Data Visualization
We have launched an abundance of rockets and thousands more satellites into orbit since the 1950s, when the space era first began. Since the launch of Sputnik, the first artificial satellite to orbit Earth, by the U.S.S.R. on October 4, 1957, humans have been exploring the space. This took place during the Cold War, a time when the Soviet Union and the United States were at odds politically. There are still plenty, and as we launch more, the probability of collision grows. Thousands of defunct satellites as well as fragments from all the rockets we've ever fired are in orbit around our planet. Any human-made item in orbit around the Earth that is no longer usable is known as orbital trash. Non-operational spacecraft, abandoned launch vehicle stages, mission-related junk, and fragmentation debris are examples of this debris. Fortunately, space trash doesn't currently represent a serious threat to our explorations. Its greatest threat is to other satellites that are in orbit.
To avoid being hit, damaged, or destroyed by all this approaching space junk, these satellites must maneuver out of the path. Every year, hundreds of collision avoidance maneuvers are carried out across all satellites. If there is too much space debris in orbit, the Earth's orbit may become unstable due to a chain reaction whereby more and more objects hit and produce fresh space debris. This condition is known as the Kessler Syndrome. Although this scenario would be severe, some experts are concerned that a variation of it might become an issue in the future. In addition to the debris we've left in Earth's orbit, there are other items on the lunar surface and other planets. Space Anthropocene 2.0 has displayed the objects and detritus left in space to investigate these explorations and see how it has altered over time. Data from NASA and the UN were used to collect and evaluate events between 1957 and 2022.
