While this does not remove the debris of the now derelict rocket stage or satellite itself, it does substantially reduce the likelihood of the spacecraft destructing and creating many smaller pieces of space debris, a phenomenon that was common in many of the early generations of US and Soviet [74] spacecraft.
The fragments can then hit other objects, producing even more space debris: if a large enough collision or explosion were to occur, such as between a space station and a defunct satellite, or as the result of hostile actions in space, then the resulting debris cascade could make prospects for long-term viability of satellites in particular low ...
Human explorers may be potential carriers back to Earth of microorganisms acquired on Mars, if such microorganisms exist. [45] Another issue is the contamination of the water supply by Earth microorganisms shed by humans in their stools, skin and breath, which could have a direct effect on the long-term human colonization of Mars.

Artificial light at night is one of the most obvious physical changes that humans have made to the biosphere, and is the easiest form of pollution to observe from space. [298] The main environmental impacts of artificial light are due to light's use as an information source (rather than an energy source).
Pollution is the introduction of contaminants into the natural environment that cause harm. [1] Pollution can take the form of any substance (solid, liquid, or gas) or energy (such as radioactivity, heat, sound, or light). Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring contaminants.
A related subject, space weather, deals with dynamic processes in the solar-terrestrial system that can give rise to effects on spacecraft, but that can also affect the atmosphere, ionosphere and geomagnetic field, giving rise to several other kinds of effects on human technologies.
The larger piece of space debris had carbon fiber composite and honeycomb structure, weighing nearly 100 pounds (45 kg). It was part of the Axiom 3 Dragon trunk section that reentered on 26 February over that region. [57] [58] On 21 May 2024, a fragment of reentered space debris was found in Haywood County (North Carolina, US). The charred ...
