NASA Perseverance Rover: Exploring Mars

[Parson]

Far out man!

 

[Robert Zwilling]

The descent looked a bit fast. I thought maybe it was the frame speed but I found a text interview that explains everything really good. The descent was fast for 3 reasons. They don't know if flying close to the ground for a period of time is a good idea. Then there is the question of dust suddenly flying up that blocks out the optics for controlling the landing. They also want a landing that is a good positive contact, liker sticking it in a gymnasts landing, hence the little bounce at the end of the landing.

I found all I wanted to know in the text transcript of the Nasa press conference. Also has details about future flights and plans. A 50 lb helicopter is being discussed, that is about the max size that they can pack with the current rover plans. That would have around 10 lbs of science instruments on it. After that, a vehicle if included, it would be smaller, function as a support vehicle for a larger helicopter.

That’s dope!

I am just a bit disappointed it didn't shoot those spongy nerf darts as well.

And now the rover is producing oxygen, which looks like another technology proof-of-concept for potential colonization:

Interesting. This is a process done in reverse in Advanced Gas Cooled Reactors. Some of the CO2 used for heat transfer breaks down to Carbon Monoxide. The gas is treated by adding oxygen to reconvert back into CO2.

What is interesting about the photo above is the lack of light polution and the clear view of the galaxy spiral.



Don't think these additional lumps of debris you Earthlings keep chucking up here are going unoticed by the way. We'll be sending them back with interest in the coming years.

Plus a thin atmosphere compared to Earth.

Best selfie I've ever seen.

That's fantastic, thanks for posting. I wonder if Earth is somewhere in that (night?) sky.

So do I.
If it's there, I lack the astronomical skill to find it. I assume it would have a blue tint.

I assume it would have a blue tint.

Is that because Mother Earth is getting on a bit (4.54 billion years and counting) and so got her hair dyed...?
