Other space stations, such as China’s Tiangong space station and Russia’s Mir space station (which operated until 2001), are smaller in comparison.

Is the space station dangerous for Earth?

Space stations, like the International Space Station (ISS), orbit Earth at altitudes above the majority of the Earth’s atmosphere, lessening the likelihood of them directly endangering the planet. However, specific scenarios could potentially pose risks.

Catastrophic failures or collisions in space might lead to debris reentering Earth’s atmosphere, posing a danger to people and property below. Although space agencies carefully plan and monitor missions to mitigate this risk, any uncontrolled reentry would likely result in debris falling into uninhabited areas, such as the ocean. Moreover, space stations are maintained to prevent contamination, with strict protocols in place to contain and neutralize any potential hazards.

While there is a remote possibility of a space station losing control and reentering Earth’s atmosphere in an uncontrolled manner, space agencies closely monitor their status and have contingency plans to deorbit them safely. Additionally, space stations are designed to burn up upon reentry, further minimizing the risk of debris reaching the Earth’s surface.
