During Ingenuity’s fourth flight, a microphone included with the SuperCam instrument aboard Perseverance captured the humming sound of the blades and the din of wind.
The audio is recorded in mono. Scientists made it easier to hear by isolating the 84 hertz helicopter blade sound, reducing the frequencies below 80 hertz and above 90 hertz, and increasing the volume of the remaining signal. Some frequencies were clipped to bring out the helicopter’s hum, which is loudest when the helicopter passes through the field of view of the camera.
Once they suss it all out,I hope they will send a whole fleet of drones to explore some of the deep canyons of Mars.
kicking off a new demo phase where we test this new tech and see how it can aid future missions on Mars and other worlds.
for a helicopter to fly is Venus ... how cool would that be !
about 698 K
1 gridded map. The global average nightside surface temperature of Venus is about 698 K with a spatial variation of over 230 K. Due to very thick and reflective atmosphere7,8,9,10, Venus surface absorbs about 2.5% of incident solar flux as compared to about 50% on
Space agency Roscosmos is planning to launch the Venera-D mission towards the end of this decade, which would mark the first landing on the planet since the Soviet era.
The Moscow Aviation Institute says one option to carry out the planned surface and atmospheric studies is to use drones to obtain data on cloud layers at different altitudes or explore specific areas of surface interest.
Two senior academics, Viktor Vorontsov and Mikhail Yatsenko, presented the proposal during the 45th Korolev Readings event which specialises in space exploration.
The presentation outlined the prospects for developing a 15kg multi-rotor vertical take-off aircraft capable of lifting 60% of its weight as a payload, but with dimensions small enough to fit into the Venera spacecraft.
