"The hardware groups suspect that that is one other piece of Dacron netting, based mostly on the noticed 2×2 mm2 grid mesh sample," NASA stated.

NASA’s Jet Propulsion Laboratory (JPL) says that a viral picture of a clump of stringy materials photographed on the floor of Mars is probably going Dacron netting.
The fabric can also be utilized in thermal blankets, in line with an company weblog publish.
Nevertheless, earlier than the string might be imaged by the higher-resolution Mastcam-Z cameras, it was blown away by the wind.
“The hardware groups suspect that that is one other piece of Dacron netting, based mostly on the noticed 2×2 mm2 grid mesh sample,” stated Justin Maki, JPL’s imaging scientist and Mastcam-Z deputy principal investigator. “They famous that this explicit piece of netting seems to have undergone important unraveling/shredding, suggesting that it was subjected to robust forces.”
Extra photos of Entry, Descent, and Touchdown (EDL) system particles from NASA’s Perseverance rover within the Hogwallow Flatts area have been shared, together with a bit of multi-layer insulation that was doubtless from the skycrane.
The skycrane crash website is situated two kilometers (1.2 miles) to the southeast.
Maki stated that it seems the fabric was blown by the wind over the course of a number of days or perhaps weeks.
“The dot sample on the fabric matched the sample of the thermal blankets put in onto the spacecraft. The blankets have been made in considered one of two varieties: Perforated Aluminized Kapton or Mylar – the intense materials was doubtless considered one of these two supplies. Subsequent photos of the blanket confirmed that it was snagged on a rock and might be seen flapping within the breeze,” he defined.
Extra Dacron netting materials was photographed in June.
As of July 24, the NASA operations workforce has cataloged round half a dozen items of suspected EDL particles within the space.
Maki famous the primary EDL particles was noticed in Hogwallow Flats on April 16. JPL stated it seems to be a “pure amassing level for windblown EDL particles.”
Whereas members of the Mars Perseverance rover workforce are checking to see if the fabric might pose as a possible contamination supply for its pattern tubes, no quick considerations have been recognized to date.
