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.
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.

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 ...

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.
There are also examples to prove that since Apollo 17 completed its mission and stayed in Low Earth orbit in 1972, human-crewed space missions in Low Earth orbit have ceased to exist. [48] In this way, it is a reasonable assumption that the closer Moon could be the next object to be explored when the gaze is not limited to LEO. [13]
There are 1 million pieces of space junk orbiting Earth right now.
