How much garbage did people leave on Mars?

Chagri Kilic, a robotics researcher at West Virginia University, has calculated that over 50 years of exploring the surface of Mars, humans have left 7,119 kilograms of debris on the planet. Kilich calculated in kilograms the mass of all spacecraft ever sent to the Red Planet and subtracted the weight of the still working - 9979 - 2860 = 7119. In total, there are three main types of debris on Mars - discarded equipment (for example, containment shells of spacecraft), inactive or broken devices.
