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.

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 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 ...
There are 1 million pieces of space junk orbiting Earth right now. Amber Yang is on a mission to clean up space trash: 'We’re being trapped by another layer of pollution' Skip to main content
The Space Sustainability Rating was first conceptualized at the World Economic Forum Global Future Council on Space Technologies designed by international and transdisciplinary consortia. [14] The four leading organizations are the European Space Agency , Massachusetts Institute of Technology , University of Texas at Austin , and BryceTech with ...
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.
A cloud of methane about 2 miles long was discovered southeast of Carlsbad by NASA, amid the Permian Basin oilfields.
Some critics have pointed out the hazards of space debris which affect satellites, spacecraft and the surface of the Earth. For example, in March 2009 debris believed to be a 10 cm (3.9 in) piece of the Kosmos 1275 satellite nearly hit the ISS. [37] Although it is relatively rare for people on the ground to be hit by space debris, it does happen.
