The scientist counted how many people left the garbage on Mars

The debris on Mars comes from three main sources: abandoned equipment, an inactive spacecraft and a crashed spaceship, and now Chagri Kilić, a postdoctoral robotics scientist from the University of West Virginia, has counted how much space debris people have left behind during the study of the Red Planet.

There are now nine inactive spacecraft on Mars: Mars 3, Mars 6, Viking 1, Viking 2, Phoenix, Sojourner and Spirit, the previously lost Beagle 2 landing module, and the recently lost Opportunity spaceship, mostly untouched objects, and they can be considered historical relics rather than debris.

In July 2021, for example, Perseverance dropped a drilling dock onto the surface, allowing it to replace a new, untouched piece so that it could continue to collect samples.

Also, at least two spacecraft have crashed in recent decades and four others have lost contact before or immediately after landing.

Over the years, researchers have found many small-scale wind-blown debris, such as recently found netted material and a large shiny heat blanket stuck in rocks.

If you add up the mass of all the spacecraft ever sent to Mars, it's about 9,979 kg, and if you subtract the weight of the current ship on the surface -- 2,860 kg -- it leaves 7,119 kg of debris on Mars.

The scientists are very concerned about the debris on Mars, it's dangerous for current and future missions, and the Perseverance teams are documenting all the debris they found and checking whether any of them can contaminate samples that collect rovers or prevent them from moving, and so both Curocity in 2012 and Opportunity in 2005 encountered debris from their landing machines.

In addition, spaceships and parts of them are the first landmarks in human exploration of planets.
