    Now the view from Perseverance.

    Over now. This was historic enough to get me to stay up to watch. The first aircraft flight on another planet.

    Yes, well, I guess we can say “we were there at least as much as possible.” I get a kick that I was watching on my tablet (something that was science fiction until fairly recently) to see an event that was also science fiction until now.

    I hadn’t heard this before. From:

    https://www.bbc.com/news/science-environment-56799755

    Ingenuity even carries a small swatch of fabric from one of the wings of Flyer 1, the aircraft that made that historic flight at Kitty Hawk, North Carolina, more than 117 years ago.

    So a part of the first successful powered heavier than air aircraft has now flown as part of the first aircraft on another planet. More symbolic than substance, I know, but that still feels very special to me. I’m sure Orville and Wilbur never imagined part of their plane would fly to and on Mars.

    The photo of the shadow is cool, but Iím surprised the blade shadows donít have some kind of motion artifact.

    Of course, I know nothing about the camera.
    Still, maybe I should start my own CT

    Well done Ingenuity team.

    Looks like a great flight in the atmosphere.

    With guys like Musk and the private sector and other national space groups one day hoping to copy or one day add to what JPL does, Mars will get busy. I dont imagine something big like a StarWarsStarTrek sized transport getting jammed in sideways blocking up the Valles Marineris traffic and needing new safety rules like what happened in the Suez but maybe it's going to be a busy planet some day. I wonder if one day someone will push for a 'Mars Treaty', I think some space disputes are addressed through the ITU, a group called the International Telecommunication Union? Your Private sector Mars Robo-Drone must always give right of way to Manned Martian aircraft, your Flying Mars Robot must stay away from the Martian antonymous national parks otherwise the drone might disturb the special bio-engineered microbes, plants and genetically engineered animals inside these Bio-Dome parks. I wonder how long, how many decades / century before flight rules, traffic rules and regulations about interactions between vehicles becomes a thing? Class G or Martian Robots obeying the laws of Class-Mars with Visual flight rules?
    I like some of the unique footage of our Earth-based helicopters, no idea about the ISO speeds, shooting interval or Frames per second but one of my favorite type of Aircraft footage back down on Earth is when Helicopter Rotor Blades are matched by Camera Shutter Speed frame rates, you get this effect where it looks like a 'magical' tv show God-hand is lifting the helicopter without rotor blades moving.

    The Mars on board nav cam must have a very high shutter speed for showing shadow of Ingenuity in flight

    Looked like a good first test.

    Well done Ingenuity team.
    Well the blade rotation is reported to be 40 revs per second. With diameter 1.2 m that is quite a fast tip speed 140 + m/s?

    Hmmmm...maybe I'm missing it but there does not seem to be a section on the github site or on the JPL site for images taken from Ingenuity. Only from the rover. Maybe that will change in the next week or so.

    Ingenuity has two cameras onboard. A black-and-white camera that points down to the ground, which is used for navigation, and a high-resolution colour camera that looks out to the horizon.

    A sample navigation image sent back to Earth revealed the helicopter's shadow on the floor of the crater as it came back in to land. Satellites will send home more pictures of the flight over the next day. There was only sufficient bandwidth in the orbiters' first overflight to return a short snatch of video from Perseverance, which was watching and snapping away from a distance of 65m. Longer sequences should become available in due course.

    Hey, actual "video" taken of the flight. I expect it's just a series of still images stitched together - but isn't that called a movie?

    Nice! That's one short flight for a helicopter, one giant leap for mankind (or something like that).

    Amazing lack of dust kick up compared to what I expected
    With sufficient thrust, water towers fly just fine.

    I wonder if the previous test of just spinning up the rotors blew it away and there wasn't much new deposit yet.

    Maybe plane tickets, space tourism to Moons and Planets will be a real thing,

    first flight (IGY-1), call sign (INGENUITY) and our backcountry airstrip in Jezero Crater, Mars (JZRO).

    Ingenuity now has its own ICAO designator and a pilot logbook

    Should have given it a tail number.

    And an intern to paint it on the tail?

    One of the tweets said itís cleaner than it started, by shaking off a fair amount of dust.

    I expected it would make its own cleaning events one way or another, what with the blades spinning and it moving air and moving itself through the air.

    Maybe they could fly it over to Insight, which has had to go into hibernation due to dusty panels and needs a cleaning!

    My understanding is it is a combination of dusty solar panels and Mars winter, which by itself leads to low power levels.

    Could it be "That's one short flight for a helicopter, one giant spin for NASA PR" ?

    As a senior employee, it is your duty to try to get the new intern to do an impossible /non existing task. Like getting a bucket of sparks to refill the spark plugs, or looking up the recommended octane level of a Tesla. Or, in this case, painting the tail number onto a tailless helicopter.
