Mars is littered with 15,694 pounds of human trash from 50 years of robotic exploration. What should we do with it? (via ConversationUS)
who studies ways to track Mars and Moon rovers. In mid-August 2022, NASA confirmed that the Mars rover Perseverance had spotted a piece of trash jettisoned during its landing, this time a tangled mess of netting. And this is not the first time scientists have found trash on Mars. That’s because there is a lot there.
All spacecraft that land on Mars eject equipment–like this protective shell–on their way to the Martian surface.Debris on Mars comes from three main sources: discarded hardware, inactive spacecraft and crashed spacecraft.that protects the spacecraft. This module includes a heat shield for when the craft passes through the planet’s atmosphere and a parachute and landing hardware so that it can land softly.
The craft discards pieces of the module as it descends, and these pieces can land in different locations on the planet’s surface – there may be a lower heat shield in one place and a parachute in another. When this debris crashes to the ground, it can break into smaller pieces, as. These small pieces can then get blown around because of Martian winds.
The Perseverance rover came across this piece of netting on July 12, 2022, more than a year after landing on Mars.
