Helicopter on Mars!

This is only like a 2 frames animation of the blades starting to spin

The flight attempt is today, but we won't get full images or videos for a few days (because transmitting a lot of data from another planet takes... some time. Space is big)

seems they did it, helicopter flying on mars

https://old.reddit.com/r/space/comments ... _an_alien/

I say "seems" because I can't find that video on NASA's Maras helicopter website or their youtube channel

https://mars.nasa.gov/technology/helicopter/

Correction, there's a 47 minutes video of stream from today, maybe it's in there

Ingenuity Mars Helicopter completed 2nd flight to 5 meters altitude

Image

This is the first color image of the Martian surface taken by an aerial vehicle while it was aloft. The Ingenuity Mars Helicopter captured it with its color camera during its second successful flight test on April 22, 2021. At the time this image, Ingenuity was 17 feet (5.2 meters) above the surface.

And for the third time, THIS is flying

https://youtu.be/kNx9hcrUpww

Starts at the bottom left, rises up, and then flies across al the way to the right and off the screen, for a few seconds, then returns to the start.

There's also a new still pic

Image

I guess those are its own feet at the sides, and its shadow at the bottom.

It's just a small mango. (pic from the internet, it's not the season here yet)

The 3 colors is probably because it got more sun in one side.

It's a video from Mars, camera turning around a rover. There's sound. Source had NO info or links.

I'm sure I heard breathing, sounded human to me, about 29 seconds in, or 10 seconds before the video ends.

So... fake sound... right? Image

Well, "video" ain't quite right. The image that was used in that clip was clearly stiched together from probably two separate images which can be seen by the identical sharp change in color at the 10- and 33-second marks AND the much more subtle color changes that can be seen at the 20-second mark (this one was created with several horizontal breaks in part to "preserve" the continuity of Perseverance's top where the slight change in image angles between those shots would have caused noticeable "breaks" in the gear atop of Perseverance). I'm uncertain why the creator chose to jerkily move the camera view--I'm fairly certain that Perseverance's camera arm is capable of MUCH smoother movements--except that perhaps the maker purposefully intended to simulate a human holding a video camera and slowly turning in place.

The sound is likely also partly simulated. The audio could be taken from one of NASA's videos but my guess is that maker at least added what sounds like a person stepping in place on a crunchy surface in order to turn. For that reason I changed the above paragraph: I believe the maker did this deliberately.

Ah, the video creator took the image from this NASA press release. In addition to smoothing out some of the picture breaks in the original stitched together from 142 images, the video creator also supplemented the top with additional sky (easy enough to do with just a bit of copy-n-paste). That big color break that happens around the 10- and 33-second marks was unavoidable because NASA didn't bother to color-correct the left end of their image with the right end.

This one is from NASA

Watch — and hear — NASA’s Ingenuity copter zip around on Mars

NASA just released video and audio of its mini Mars helicopter, Ingenuity, flying around the Martian surface during its fourth flight test, as captured by the craft’s robotic partner Perseverance from nearly a football field’s distance away.

The footage, combining audio and video of an Ingenuity flight test for the first time, starts off with the soft, rumbling hum of the Martian wind. Ingenuity can be seen stationary on the surface in the right-hand corner of the frame before taking off for flight. When the copter ascends, the ambient hum intensifies; the faint, muffled sound of Ingenuity’s twin rotor blades spinning at 2,537 RPM picks up and it eventually zips across the frame.
