Learn how satellite design choices can reduce space debris through safer materials, passivation, drag control, and end-of-life disposal.

Space junk is a growing orbital hazard. Learn how dangerous it is, what it can damage, and how agencies reduce the risk.

Learn how satellites use solar panels, store energy, and keep missions running in sunlight and eclipse.

Learn how the Kessler syndrome develops, why collisions can multiply debris, and what space agencies are doing to reduce the risk.

Learn what space junk is, why it matters, and how satellites, rockets, and cleanup efforts are shaping orbital safety.

Learn how the International Space Station tracks, dodges, and survives orbital debris with precise warnings, maneuver planning, and spacecraft coordination.

Old satellites become space junk because they lose control, stop communicating, and remain in crowded orbits where collisions and fragmentation can cascade.

Satellite collisions are rare, but the growing volume of space traffic is changing the odds and the consequences.

Learn how satellites generate, store, and manage power using solar arrays, batteries, and onboard systems in the harsh environment of space.
