    Thanks Trebuchet, the video was helpful, so basically it's experimental testing for future drone missions.

    I heard 90 seconds. And equivalent to 100000 feet up here with about 1% atmosphere.

    Some of them are really clear showing pebbles around one of the wheels.

    I liked the one showing pebbles and grit in one of the wheels. Since Percy hasn't budged yet, I'm guessing the jetpack blew debris into the wheel cavity just as it flew away to crash.

    Having just viewed the wonderful Perseverance landing video, i noted how violently the dust was disturbed by the thrusters, yet the rocks apparently did not appear to move in the landing footage. The ''holey'' rocks especially, being observably porous, would move rather easily one would have thought ? I note the debris on the buggy itself, but the landing video showed only dust disturbance, as far as i could tell. And the small and larger rocks seemed to show no dislodging. ?

    What's up with all the spikes? I was expecting blueberries.

    I'm reminded once again about what the BA said about the Phoenix lander being imaged by the Mars Reconnaissance Orbiter:
    Think on this, and think on it carefully: you are seeing a manmade object falling gracefully and with intent to the surface of an alien world, as seen by another manmade object already circling that world, both of them acting robotically, and both of them hundreds of million of kilometers away. Never, ever forget: we did this. This is what we can do.

    "NASA's Mars Perseverance Rover Provides Front-Row Seat to Landing, First Audio Recording of Red Planet"

    https://www.marsdaily.com/reports/NA...lanet_999.html

    New video from NASA's Mars 2020 Perseverance rover chronicles major milestones during the final minutes of its entry, descent, and landing (EDL) on the Red Planet on Feb. 18 as the spacecraft plummeted, parachuted, and rocketed toward the surface of Mars. A microphone on the rover also has provided the first audio recording of sounds from Mars. JPL also issued the first detailed panorama from the landing site

    "Caught on Camera! Perseverance Rover, Discarded Landing Hardware"

    https://www.leonarddavid.com/caught-...ding-hardware/

    The NASA Mars Reconnaissance Orbiter’s HiRISE camera system has spotted the Perseverance Rover on the surface of the Red Planet. Imagery also shows many parts of the descent system that got the safely down.

    Any word as to why no audio was captured during EDL? It would have been icing on the cake.

    What was the data path for that video? All stored onboard of Perseverance and then uploaded afterwards, or sent realtime to MRO or something and sent to earth later?
    With sufficient thrust, water towers fly just fine.

    They say they did but I did not hear any Maybe it was recoded after the landing and not released yet.

    A microphone attached to the rover did not collect usable data during the descent, but the commercial off-the-shelf device survived the highly dynamic descent to the surface and obtained sounds from Jezero Crater on Feb. 20. About 10 seconds into the 60-second recording, a Martian breeze is audible for a few seconds, as are mechanical sounds of the rover operating on the surface.

    I suppose carbon fiber is too soft. Still, aluminum in a high friction load bearing application . I hope they chose their alloy with extreme care.

    If Scott Manley is right, there was more than one microphone and the one that was supposed to capture sound on descent failed. (That’s from his commentary in his video -https://m.youtube.com/watch?v=mfgzTfw_J6o).

    Although I would have preferred the microphone to work, we already have the sound of wind from Insight.

    Mars 2020 Rover - "Perseverance"

    I’m hoping to hear the rover driving over the surface. I have the following image in my mind:

    "Mastcam-Z's First 360-Degree Panorama"

    https://www.marsdaily.com/reports/Ma...orama_999.html

    NASA's Mars 2020 Perseverance rover got its first high-definition look around its new home in Jezero Crater on Feb. 21, after rotating its mast, or "head," 360 degrees, allowing the rover's Mastcam-Z instrument to capture its first panorama after touching down on the Red Planet on Feb 18. It was the rover's second panorama ever, as the rover's Navigation Cameras, or Navcams, also located on the mast, captured a 360-degree view on Feb. 20.

    Mastcam-Z is a dual-camera system equipped with a zoom function, allowing the cameras to zoom in, focus, and take high-definition video, as well as panoramic color and 3D images of the Martian surface. With this capability, the robotic astrobiologist can provide a detailed examination of both close and distant objects.

    Here is to hoping they take a chance and examine the skycrane impact zone this time. They may see a rock newly split in two.

    May be too much hazard associated with that; unexpended propellants and such.

    NASA has awarded the Mars Ascent Propulsion System (MAPS) contract to Northrop Grumman Systems Corporation of Elkton, Maryland, to provide propulsion support and products for spaceflight missions at the agency's Marshall Space Flight Center in Huntsville, Alabama.

    "NASA's new Mars rover hits dusty red road, 1st trip 21 feet"

    https://abcnews.go.com/Technology/wi...d-1st-76286586

    NASA’s newest Mars rover hit the dusty red road this week, putting 21 feet on the odometer in its first test drive.

    The Perseverance rover ventured from its landing position Thursday, two weeks after setting down on the red planet to seek signs of past life.

    The roundabout, back and forth drive lasted just 33 minutes and went so well that more driving was on tap Friday and Saturday for the the six-wheeled rover.

    “This is really the start of our journey here,” said Rich Rieber, the NASA engineer who plotted the route. “This is going to be like the Odyssey, adventures along the way, hopefully no Cyclops, and I’m sure there will be stories aplenty written about it.”

    21 feet in 33 minutes? Sounds like Dallas rush hour traffic.
