¿ Astronomy Picture of the Day [1]Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. 2021 April 20 IFRAME: [2]https://www.youtube.com/embed/wMnOo2zcjXA?rel=0 Ingenuity: First Flight over Mars Video Credit: [3]NASA, [4]JPL-Caltech, [5]ASU, [6]MSSS Explanation: What's the best way to explore Mars? Perhaps there is no single best way, but a newly demonstrated method shows tremendous promise: flight. [7]Powered flight has the promise to search vast regions and scout out particularly interesting areas for more detailed investigation. Yesterday, for the [8]first time, powered flight was demonstrated on Mars by a small helicopter named [9]Ingenuity. In the [10]featured video, Ingenuity is [11]first imaged by the [12]Perseverance rover sitting quietly on the Martian surface. After a few seconds, [13]Ingenuity's long rotors begin to spin, and a few seconds after that -- history is made as Ingenuity actually takes off, hovers for a few seconds, and then lands safely. More tests of [14]Ingenuity's unprecedented ability are planned over the next few months. [15]Flight may help humanity [16]better explore not only Mars, but [17]Saturn's moon [18]Titan over the next few decades.
