Por NASA Podcast #Recomendado Tweet Gravity Assist: A Dream, a Team, a Chance to Fly on Mars, with MiMi Aung he idea for NASA’s Mars Ingenuity helicopter began at the Jet Propulsion Laboratory with a team of dedicated engineers who believed in something seemingly impossible. MiMi Aung served as the project manager on the helicopter, which has now achieved nine flights on Mars. In this episode of Gravity Assist, she shares the history of the helicopter project as well as her secrets for leading groups of people to accomplish things no one has ever done before.

Por NASA Podcast #Recomendado Tweet Listen to NASA’s Ingenuity Mars Helicopter in Flight For the first time, a spacecraft on another planet has recorded the sounds of a separate spacecraft. NASA’s Perseverance Mars rover used its SuperCam microphone to listen to the Ingenuity helicopter on April 30, 2021 as it flew on Mars for the fourth time. 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. Even during flight when the helicopter’s blades are spinning at 2,537 rpm, the sound is greatly muffled by the thin Martian atmosphere. It is further obscured by Martian wind gusts during the initial moments of the flight. Listen closely, though, and the helicopter’s hum can be heard faintly above the sound of those winds. Scientists made the audio, which is recorded in mono, easier to hear by isolating the 84 hertz helicopter blade sound, reducing the frequencies bel...
