Exploring the Capitalization of the Cosmos
In a fascinating revelation, data visualizations published by The Wall Street Journal have shed light on the commercialization of outer space and the growing concern of space debris around Earth.
The visualizations highlight the need for effective space debris management to ensure the long-term sustainability of space activities. They illustrate the growing importance of space situational awareness for the safe operation of satellites and spacecraft.
Firms, not governments, are the most frequent launchers of satellites. Since 2017, companies like SpaceX have launched hundreds of observation satellites primarily for broadband internet services and network coverage enhancement. Their Starlink constellation, for instance, provides global satellite broadband, including integration with mobile and future 6G networks.
Military and government players like Boeing have also developed satellites with advanced communication and earth observation payloads for secure military communications and tactical applications. Observation satellites are widely used for earth monitoring, environmental surveillance, urban planning, and climate simulations by programs such as Copernicus.
However, these developments have come with a cost. The data visualizations indicate an increase in the number of objects in low Earth orbit. At least 24,000 manmade objects are currently orbiting Earth due to rocket launches and satellite failures. The majority of these objects are defunct satellites, and there is a significant number of spent rocket stages in orbit.
The increase in objects in low Earth orbit is primarily due to the commercialization of outer space. This growth poses a potential threat to future space missions, as the density of objects in low Earth orbit is highest in the altitude range of 700 to 1,000 kilometers.
Currently, there are 2,000 satellites orbiting the Earth. The data visualizations suggest that the commercialization of outer space has led to an increase in space debris, which could potentially disrupt the safe operation of satellites and spacecraft in the future.
As we continue to explore and harness the potential of space, it is crucial to address the issue of space debris to ensure the long-term sustainability and safety of our space activities. Space situational awareness and effective space debris management will play a vital role in this endeavour.
