Listen closely, though, and the helicopter’s hum can be heard faintly above the sound of those winds. It is further obscured by Martian wind gusts during the initial moments of the flight. Even during flight when the helicopter’s blades are spinning at 2,537 rpm, the sound is greatly muffled by the thin Martian atmosphere. With Perseverance parked 262 feet (80 meters) from the helicopter’s takeoff and landing spot, the mission wasn’t sure if the microphone would pick up any sound of the flight. NASA’s Perseverance Mars rover used its SuperCam microphone to listen to the Ingenuity helicopter on Apas it flew on Mars for the fourth time. NASA’s Ingenuity Mars Helicopter in Flightįor the first time, a spacecraft on another planet has recorded the sounds of a separate spacecraft.are adequately mapped.Įven when adequately plotted, the particulars of how an ecosystem thrives can remain unknown and are only observed through the aid of submersibles during extensive research projects. "Past studies have highlighted some coral in the region, particularly closer to the coast and in shallower waters, but until we had a complete map of the region, we didn’t know how extensive this habitat was, nor how many of these coral mounds were connected," Cantwell stated.Įven with the conclusion of the extensive exploration, scientists estimate that only 50% of the waters around the U.S. The region is known to be a habitat for many species of invertebrates and fish, but because of its depths, the corals remain not well understood by humans. "For years, we thought much of the Blake Plateau was sparsely inhabited, soft sediment, but after more than 10 years of systematic mapping and exploration, we have revealed one of the largest deep-sea coral reef habitats found to date anywhere in the world," Kasey Cantwell, operations chief for NOAA Ocean Exploration, said in a statement.Ī subregion known as "Million Mounds" makes up a sizable part of the reef and could be hundreds, if not thousands, of years old.
