Explanation: Slung beneath its rocket powered descent stage Perseverance hangs only a few meters above the martian surface, captured here moments before its February 18 touchdown on the Red Planet. The breath-taking view followed an intense seven minute trip from the top of the martian atmosphere. Part of a high resolution video, the picture was taken from the descent stage itself during the final skycrane landing maneuver. Three taut mechanical cables about 7 meters long are visible lowering Perseverance, along with an electrical umbilical connection feeding signals (like this image), to a computer on board the car-sized rover. Below Perseverance streamers of martian dust are kicked-up from the surface by the descent rocket engines. Immediately after touchdown, the cables were released allowing the descent stage to fly to a safe distance before exhausting its fuel as planned.

Humanity is capable of some absolutely amazing things..
What’s the APOD list?
Wow. Well done.
So there is such a thing as a sky hook...
If you have a scroll mouse, scroll to go up/down and hold the Shift key down to go left and right.
Lot of people don’t know about the Shift = left/right scroll trick.
Ctrl + to zoom in more or Ctrl and scroll.
Here’s a video of computer simulation with a bird’s eye view of the descent and landing, https://www.youtube.com/watch?v=bxqgUJg9iKc
It is the list of users that get a notice that the latest NASA Astronomy Picture of the Day (APOD) has been posted on FR. I currently maintain the list that gets a message after the post is made.
Amazing picture. Amazing landing. The spacecraft begins its descent with an aeroshell / heat shield, then it deploys a parachute, then the lander lowers the rover on cables to touchdown. That’s a lot of systems that have to go just right for it to be a success.
What a pic. Looks like an animation.
That will be a classic pic.
Endeavor to persevere.
Josey Wales, excellent.
To me, launching vehicles outbound from earth is not astronomy.
Thanks. Exactly what I wanted to see.
Wow, amazing animation. That really explains the whole entry and landing process.
Just last week my computer genius buddy was amazed when he saw me hit ctrl+enter to complete and enter a web address.
Awesome picture.
Is that some form of gatling gun? On bottom right of vehicle in picture.
Martian mini-gun?
There’s a Chinese rover supposed to be there soon, right? Maybe ready for trouble.
I think the folks at NASA/JPL should be notified.
Yes. Very excellent.
