Composite Artemis II Animation Shows Just How Much Stuff Is in Low Earth Orbit
Gizmodo • • general
Key Points:
- The Artemis II mission provided rare first-hand images showing the crowded nature of low Earth orbit (LEO), capturing numerous small points of light that are actually satellites and debris orbiting Earth.
- Current satellite catalogs estimate between 33,000 and over 50,000 objects orbiting Earth, with the majority in LEO, and the number of objects has nearly tripled since 2020, increasing from around 6,000 to over 16,000.
- The growing amount of space debris poses significant risks to rocket launches and satellites, as objects in LEO travel at extremely high speeds (about 17,550 mph), making even small fragments potentially catastrophic upon collision.
- On-orbit collisions at such high velocities result in explosive impacts that can generate vast amounts of debris, with kinetic energy comparable to large bombs, thereby exacerbating the space junk problem and threatening space operations.
- While the images from Artemis II offer a stunning view of Earth, they also highlight the urgent need to address the escalating issue of space debris to ensure the safety and sustainability of space activities.
