We have not set foot on Mars yet...and our waste exceeds 8 tons on the Red Planet

Weather of Arabia - Although human feet have not yet set foot on the land of Mars, their devastation preceded them to the Red Planet. Tons of waste created by humans are today dumped on its surface, about 8 tons of waste left by humans on the surface of Mars in the past fifty years.

This waste includes discarded instruments, inactive spacecraft, and those that have crashed on Mars - specifically the Soviet Union's Mars 2 rover that landed in 1971.

The rover, which landed in February 2021, took pictures of debris during its mission to collect samples from Mars that will be returned to Earth.

There are a total of nine inactive spacecraft on Mars, including Mars 3, Mars 6, Viking 1, Viking 2, Sojourner, ESA's Schiaparelli probe, Phoenix probe, Spirit rover and Opportunity rover.

According to Killick, most of the robots are still intact, and space agencies consider them historical relics rather than discarded trash.
