Listen to the 'thunk' as the new rover lands on Mars
The video shows everything from the moment that the parachute containing the delicate equipment opened, through the nail-biting seven-mile descent to the surface of Mars' Jezero Crater, and concluding with the rover actually touching down on the Martian surface. While the rover was not able to pick up any sounds during its descent, it managed to catch a faint Martian breeze after the vehicle had touched down. It also managed to record the sounds of the rover's machinery working properly on the Martian surface.
NASA has released two 18-second audio clips: One includes the noise that comes from the rover itself and the other is modified to filter it out.
When watching the video, one is particularly struck by how the Martian dust blows away from the planet's surface as the rover lands. One can see tiny grains and larger pebbles, similar to what you'd expect to find on a beach. When it finally does touch down, one of the NASA scientists proclaims excitedly, "Perseverance safely on the surface of Mars, ready to begin seeking the signs of past life." The team at NASA starts applauding and jumping with joy at the announcement.
When Perseverance touched down on the surface of Mars last week, it was the heaviest and most technologically advanced NASA rover to ever land on the Martian surface, as well as the first to do so while carrying a helicopter. It also landed in a spot that, because of its treacherous terrain, was the most dangerous where any rover had ever landed. Yet it was vital for the rover to land at the Jezero Crater because scientists believe the 28-mile wide location used to be a lake. As a result, if there ever were ancient microbial life on Mars, the Jezero Crater is a great place to start looking for it.
Mars has long been considered one of the planets most likely to currently or previously have hosted life because it used to have conditions similar to those on Earth. Some scientists even speculate that life may have come to Earth on Martian rocks that were propelled into space by a powerful impact.
The ultimate goal behind the Perseverance mission is to perform what is known as a "sample-return mission," one in which rock and soil samples are scooped up from another celestial body and returned to Earth for further study. Sample-return missions are extremely rare because of their cost, and a sample-return mission has never been performed from another planet; only moons, comets and asteroids.
