[데일리중앙 송정은 기자] Scientists have found that there could be about 7 tons of Earth’s garbage on the surface of Mars.
Kagri Kilik, a researcher on the lunar and Mars rover at the University of West Virginia in the US, said, “Excluding 3 tons, which is the weight of spacecraft and rovers currently in operation, from 10 tons, which is the mass of all spacecraft launched to Mars, the remaining 7 tons are garbage on Mars. remains,” he said.
Garbage that is currently being discovered on the surface of Mars is parts that have been removed as unnecessary, spacecraft that have stopped working, and spacecraft fragments that have fallen from impact.
Mars debris is also often found by NASA’s rover, Perseverance. NASA posted on its official Twitter account in June that “our team found something we didn’t expect” and released pictures of garbage it found on Mars.
According to NASA, “Earth debris could contaminate Mars samples collected by the rover or collide with the rover, causing equipment failure.”
Experts are also concerned about the abundance of human-made garbage on Mars, a space that humans have not yet stepped on.
