Mars Helicopter Spots Wreckage From Perseverance Landing
New pictures from the Ingenuity helicopter offer a fresh perspective of the wreckage left behind when the Perseverance rover landed on Mars last year, NASA said on Wednesday. The Verge reports: Launched in 2020, the Perseverance rover successfully landed on the Red Planet in 2021, with the mission of finding ancient signs of life on Mars. The rover carried the Ingenuity helicopter onboard -- an experimental project that scientists on Earth hoped would be able to see sights that the rover couldn't. Perseverance went through a grueling process known as the seven minutes of terror to descend onto the Martian surface. As it entered the atmosphere, a heat shield helped protect the rover from the blistering heat of reentry and slowed it down dramatically. After that, the massive parachute deployed out of the backshell (a cone-shaped part of the descent vehicle), slowing it down even more. At that point, the backshell and parachute separated from Perseverance and let the descent stage take over, using rocket thrusters and a "sky crane" to gently lower the rover to a smooth landing. On April 19th, Ingenuity took photographs that captured the remains of Perseverance's parachute and the rover's protective backshell, a cone-shaped part of the descent vehicle that carried the parachute and helped protect the rover on its way to the surface. Strewn around the site were debris from where the two crashed into the surface after separating from the rover. The backshell ended up hitting the ground at about 78 miles per hour, according to NASA. From the pictures, it appears that the parachute, the lines connecting the parachute to the spacecraft, and the coating on the outside of the backshell all survived the trip to the surface, NASA says, though more analysis of the pictures will happen in the coming weeks.Read more of this story at Slashdot.
