Read on for our NASA TV webcast guide for NASA's Mars Perseverance rover landing this week. The hope is to use such small drones for scouting ahead of astronaut missions, or exploring dangerous regions, in future Mars missions. “Both would be equally exciting for the team.Another historic first for the Perseverance mission will be a helicopter, called Ingenuity, that will test flying on Mars for the first time. The science team thinks the holes could be from gases escaping volcanic rock as lava cooled, or from fluid moving through the rock and dissolving it away. “Depending on the origins of the rocks, these holes could mean different things,” she said. The ground is strewn with rocks that are shot through with holes, said deputy project scientist Katie Stack Morgan in a news briefing on February 19. The first images Perseverance sent back from Mars showed its wheels on a flat expanse. The rover’s primary mission is to search for signs of past life and to cache rock samples for a future mission to return to Earth. Perseverance landed in an ancient lakebed called Jezero crater, about two kilometers from what looks like an ancient river delta feeding into the crater ( SN: 2/18/21). ![]() The rover also captured audio from the surface of the Red Planet for the first time, including a gust of Martian wind. Rover engineers say they also hope to hear the wheels crunch as the rover drives. The first recording included a gust of wind. Perseverance carries a microphone to record the sounds of the Martian surface. The movie looks so much like animations of the sky crane landing technique that NASA had released in the past that it almost doesn’t look real, says imaging scientist Justin Maki. “Every time we got something, people were overjoyed, giddy. “It’s hard to express how emotional it was and how exciting it was to everybody” to see the movie for the first time, said deputy project manager Matt Wallace. Finally, the sky crane disconnected the cables and flew away, leaving Perseverance to begin its mission. A camera on the sky crane showed the rover swinging slightly as it descended. Cameras on the top and bottom of the rover captured clouds of dust billowing as the rover’s jetpack, the sky crane, lowered it down to the ground on three cables. The rover filmed the ground coming closer and closer, getting glimpses of a river delta, craters, ripples and fractured terrain. “There’s no danger to the spacecraft here, but it’s something we didn’t expect, and wouldn’t have seen” without the videos, he said. NASA’s Perseverance rover captured video of its own landing using a set of cameras on the back of the entry vehicle, the sky crane and the rover itself.
