Good morning, Rallypoint. Today's Astronomy Picture of the Day (APOD) is titled "Ingenuity: First Flight over Mars." It may look like no big thing, but consider the following: 1) it takes between 5 and 20 minutes for signals to travel to Mars (or come back), 2) the helicopter needs to be autonomous (e.g. make its own decisions in real time), and 3) the flight environment on Mars is substantially different (atmosphere, gravity, etc). So without further ado, take a look at the first powered flight on another planet as seen from the rover Perseverance. Well done, NASA!

Thank you my friend Maj William W. 'Bill' Price for your diligence in posting the daily NASA Astronomy Picture of the Day (APOD). The Tuesday, April 20, 2021 Astronomy Video Clip of the Day (AVCOD) is entitled "Ingenuity: First Flight over Mars."

AVCOD background
"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. Powered flight has the promise to search vast regions and scout out particularly interesting areas for more detailed investigation. Yesterday, for the first time, powered flight was demonstrated on Mars by a small helicopter named Ingenuity. In the featured video, Ingenuity is first imaged by the Perseverance rover sitting quietly on the Martian surface. After a few seconds, 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 Ingenuity's unprecedented ability are planned over the next few months. Flight may help humanity better explore not only Mars, but Saturn's moon Titan over the next few decades."
