NASA's Perseverance rover captured an unusual image of something lying in the red sand of Mars: a bundle of string.The rover's front left hazard avoidance camera took a photo of the light-coloured object on July 12 that some people likened to spaghetti.Officials at the space agency confirmed that they believe the object to be a string left over from Perseverance's landing.The string could be from the rover or its descent stage, a component similar to a rocket-powered jet pack used to safely lower the rover to the planet's surface, according to a spokesperson for the Perseverance mission at...…NASA's Perseverance rover captured an unusual image of something lying in the red sand of Mars: a bundle of string.The rover's front left hazard avoidance camera took a photo of the light-coloured object on July 12 that some people likened to spaghetti.Officials at the space agency confirmed that they believe the object to be a string left over from Perseverance's landing.The string could be from the rover or its descent stage, a component similar to a rocket-powered jet pack used to safely lower the rover to the planet's surface, according to a spokesperson for the Perseverance mission at...WW…
