Nasa says that it has solved the mystery of a string-like object found on the surface of Mars.
The object was found by the space agency’s Perseverance rover on July 11. Until now, the origin of the item has been unknown.
Nasa said the object was a piece of Dacron netting. The material is used in thermal blankets that are designed to shield equipment from extreme temperatures when landing on Mars.

“The hardware teams suspect that this is another piece of Dacron netting, based on the observed 2×2 mm2 grid mesh pattern,” Nasa scientist Justin Maki said in a blog post on the agency’s website.
“They noted that this particular piece of netting appears to have undergone significant unravelling/shredding, suggesting that it was subjected to strong forces.”

The piece of netting had disappeared by July 16 when the Perseverance rover returned to the spot it was found.
The rover regularly comes across pieces of debris on the red planet. In June, it spotted a piece of its own thermal blanket used during its descent onto Mars.
About half a dozen pieces of debris from the rover’s landing have been logged in an area Nasa calls Hogwallow Flats.
The rover has been trawling the planet since February 2021 searching for signs of ancient life and collecting samples of rock and soil.
In 2021, Perseverance captured the first piece of audio from Mars, revealing what sound is like on the planet.
