    Such an achievement, I don't even have the words. Hover a vehicle the size of an SUV from a rocket-hovering vehicle on another planet autonomously? Amazing.

    That’s a crazy video...
    Perspective, at least my perspective, is way off, couldn’t believe when I saw the dust kicking up.... I thought it was much higher.

    Also, it’s the first time the sky crane developer saw it work.

    Historic footage for sure :thumbsup:

    Thanks for posting it :thumbsup::thumbsup:

    I felt the same way, what surprised me the most was the final phase of the landing sequence using eight hydrazine-fueled rocket jets on the Skycrane that didn't even look like they were turned on, with the hydrazine-fuel you have a clear exhaust, as opposed to what was shown in the "7 minutes of terror" animated video, showing a bluish exhaust.

    Dust is weird on Mars. Not only does it weight less, but the thinner atmosphere allows it to be kicked up easier. I remember reading somewhere that hurricane speed winds on mars would feel like a gentle breeze from Earth. The problem is that the dust it kicks up is VERY fine, and will get in EVERYTHING. I believe they compared it to baby powder, but it's been years since I read what ever I'm remembering.

    I read yesterday that only like 20 planes are in actual use with those engines.

    the vast majority have been stored since last March due to the lagging demand.

    I need some Starship launches to distract me from my RUD’ing TSLA stock.

    I used to work at a place that makes the stuff that the blades are made from. When I was there the level of attention paid to meeting specs, accuracy, and quality was astounding. They made the fan blade material, offshore oil rig drilling collars material, Navy fighter landing gear material, that kind of stuff. And guitar string material -- go figure.
