Although this was not considered possible, the ISAE-Supero microphone installed in the Super Game recorded the sounds of an ingenious helicopter flying over the sky of Mars. Explanations by ISAE-Supa ஆராய்ச்சro researcher Naomi Murdoch and Microphone Scientific Manager David Mimoun.
The ISAE-Supaéro microphone, Integrated into the French instrument Supercam and recorded the sound of 4e Flight fromIngenuity ! Did not receive a significant performance. In fact, since the helicopter is located at a safe distance of several tens of meters from the diligence, it is not certain that the microphone can hear anything.
The microphone, built into the French Super Game device, recorded the ingenious flying noise on its fourth flight. The Mars helicopter was then located 80 meters from the rover (it is better to listen with a good quality headset as Mars does not transmit high sounds well). © NASA / JBL / LANL / GNES / CNRS / ISAE-Super
The noises of the helicopter’s fourth plane were captured
During this fourth flight, the ingenuity, whose The mission was extended to 30 days, Located 80 meters from the rover. The small helicopter rose five meters above the ground before flying 133 meters and then returned to its departure point. During the flight, Supergame’s scientific microphone, developed by ISAE-Supaéro, recorded the sound emitted by the rotation of the sharp blades. As the microphone panel points out, this sound is “ A Frequency Characterization of 84 Hertz ; This is equivalent to the low “e” of a piano or the bass voice of a man .
« This is a big surprise for the whole science team! மி says Naomi Murdoch, a researcher at ISAE-Supaéro in charge of micro data. Tests “ The design of this instrument was carried out in a Martian chamber, as well as our principles for transmitting sound indicate that the microphone does not pick up the sounds of a helicopter ».
This record has proven to be a gold mine for our understanding of the Martian atmosphere.
In fact, TheAtmosphere Of Mars, very rare, « Observes sound transmission strongly, so we need a little luck to record the helicopter this far. Therefore, we are very pleased to have succeeded in obtaining this record of becoming a gold mine for our understanding of the Martian atmosphere. .
These words to David Mimon, Scientific Manager of Super Game Microphone and Professor of ISAE-Supaéro:
Futura: Technically, the performance of recording flying ingenious sounds is amazing?
David Mimoun: Yes, this is an incredible performance. We thought we were in the sensitivity range with a great deal of attention to the atmosphere, but we were lucky, or our models were pessimistic … I have to say that the sound propagation models on Mars were preliminary.
Futura: Is it difficult to eliminate external noise?
David Mimoun: We amplified the ingenuity frequency band slightly (increased the bass), especially to distinguish them from the gases in the air. However, there is no complex signal processing.
Futura: It is designed to listen to, for example, the activities of a robotic arm and mast, such as monitoring the operation of the pumps on a normal or random ground toxin or moxie device. But are other attempts to record unplanned sounds being considered?
David Mimoun: We have worked hard to convince our colleagues J.P.L. Try to check the plane for ingenuity. I think it can be used often as the microphone has shown its capabilities. Activities with Moxie are already planned, but this will increase the interest of the microphone among colleagues. But, at ISAE-Supaéro, we mainly focus on Mars Atmospheric Science, in which we have a strong expertise since Insight.
