It is estimated that 7 tons of trash left on Mars by humans.

Kagri Kalik, a researcher on Mars rover at the University of West Virginia in the US, wrote an article regarding this analysis through House Tough Works on the 22nd (local time).

“In August of this year, NASA discovered pieces of garbage that were generated during the landing of the Mars rover Perseverance,” Kalik said. .

He explained that humans have spent more than 50 years exploring the surface of Mars, sending a total of 18 objects, including spacecraft, to Mars. In the process, various kinds of garbage were generated.

According to Kalik, there are three main types of garbage on Mars. Hardware, including discarded debris, and a spacecraft that crash-landed during landing, a now inactive spacecraft.

In fact, numerous fragments are generated in the spacecraft due to the impact it receives when entering and landing in Mars’ atmosphere. These fragments are blown away by the Martian hot winds away from the landing site.

Kalik said that these fragments can be regarded as historical relics rather than just garbage.

“If you add up the weight of all the spacecraft sent to Mars so far, you get regarding 22,000 pounds (9,979 kg). Subtract the weight of the spacecraft operating on the surface, and you’re left with regarding 15,694 pounds (7,119 kg) of debris,” he said. did.

Meanwhile, NASA is documenting all debris found on the surface of Mars. Scientists are examining the possibility that these fragments might cause problems, such as contaminating the samples collected.
