and other equipment used to enter the red planet’s
atmosphere. While the spacecraft lands, parts of the
protective module are thrown away, falling at different
points. Garbage that falls on the ground can be broken
into smaller pieces and drifted further away by winds.
Perseverance, a rover designed to explore a crater on
Mars, for example, found a shiny thermal blanket stuck
between rocks. This equipment was seen 2 km away
from where the Mars probe landed. In addition, there are
nine unused spacecraft on the planet. It is stated that
at least two spacecraft have crashed on Mars so far,
and the connection with four of them was cut off before
or just after landing. However, the increasing amount
of human garbage on Mars may pose a small risk for
vehicles operating on the surface, and these materials
may contaminate the samples to be collected.
