Space Debris is what we call man-made objects in space that do not have purpose or mission. Examples include:
- Broken satellites.
- Rocket bodies.
- Dropped tools.
- Debris from collisions or explosions.
- Litter from manned space missions.
Space Debris is what we call man-made objects in space that do not have purpose or mission. Examples include:
Total of 200 000 objects. Only objects > 15 cm shown in figure.
Space Debris in Earth Orbit travels at several km/s (hypervelocity). Even a tiny object has huge kinetic energy. It can damage or destroy satellites and poses danger to astronauts. It is in practice impossible to shield against space debris, and every impact generates more debris. If unchecked, space activity will become impossible. Except for low orbits, debris will remain in space for centuries or millenia!
Satellites are crucial in modern society. We use them for navigation and timing (GNSS), communication, environmental monitoring, weather forecasting and disaster monitoring (geohazards,storms, floods, avalanches). Satellites are also used for mapping and land use, ass well as exploring the universe (e.g. Hubble Space Telescope, James Webb Space Telescope). <linke inn andre prosjekter/områder fra resten av jobs>
