NASA Perseverance Rover

Step away from this thread for a day, poke my head back in, and the kids have made a mess of things!

If the energy system failed in texas slightly below zero, how does the mars rover function on mars at 100-200 degrees below zero?

Is there absolutley 0 percent water on mars, so that the rover is not covered in icicles?

Is that dirt, dust, sand in the pictures of mars, rocks shavings that have no moisture?

Did scientist luck out and create a remote controlled car that can function perfectly in 100-200 degrees below 0, 225 million miles away from earth

Are there no elements that would effect pictures and machine function on mars, or is it like earth without any moisture?

This is a perfect example of a guy thinking he’s asking intelligent questions but is making a fool out of himself.

Well, is there instant relay between the controls on earth and the rover? Or is it a amazing programming feat, where real time adjustments are not needed

I know earths batteries dont work as well in extreme cold, i guess the rover "The MMRTG converts heat from the natural radioactive decay of plutonium into electricity." is the answer to 150 degree below zero battery problem. Mars batteries > Earth batteries

Impressive deductions and engineering we got right on the first try

All types of machines are effected by the elements on stuff we build on earth, how did they get it right on mars

and i am not trying to sound intelligent, these questions dont make sense to me.

I guess i could actually read and research the information they give, but I don't and would most likely not understand

Some of the new tech being tested and demonstrated, as well as how impressive the new landing precision is:

There's an 11 minute delay. A lot of it's functionality has to be programmed in advance that it will execute remotely and semi-autonomously.

I have this nifty little round robot vacuum cleaner. It can do its job all on its own, even maneuvers around furniture that it senses for the first time. It is programmed to map out the house and remember it. I imagine it was built by unskilled laborers somewhere in Asia.

I like to think that a rover built by NASA can do just a tad bit more.........

When are they testing the copter? I want to see that.

There will be an 11 minuet delay when they show it so it will only be close to live!

Thread back on track!

Gather around peoples!

NASA Perseverance Rover questions and observations = good to go!

Conspiracy threads = create another thread for them

Critical site rule observance? #6

Fresh slate. No members benched from thread.

Mr. Clean presses the spotless Benched-From-Thread button from this point on.

And now...

ROBOTS RULE!!!

If/when you guys have 20 minutes of time laying around this is a great little watch.

Everybody is saying how creative NASA is for achieving their goals on one try. But truth be told I had to take the wormhole in my basement to Mars and kick the dang thing to get it to work.

Checked it live on Nasa's YouTube channel. I don't think people quite understand how important this mission actually was. Epic...and watching the kids ask questions to the scientists and all the smiles on all their faces was something we need right now.

Watched some extra interviews. Very cool!

* That NASA JPL feed was kinda weirdly cool as you could pan around the control room from you're screen, even tho it was like in fish eye vision

 

[Melonfeud]

Taken not long after landing with the hazard camera when the dust from landing was still settling.

Pretty cool if you ask me.

*When I saw that in real time ,I immediately got kinda depressed , thinking: "great , this has been touted as the most advanced remote Rover to date( w/ 7 cameras no less, wait I think the copter drone has 2 itself, anyway) and these are the kind of quality photo resolutions their gonna' be releasing for general population consumption"?

 

[Melonfeud]

I haven't watched the rover videos but I am curious about how it is controlled. If it approaches a rock or something it has to navigate, how long does it take the signal from the control on earth to go 225millions miles? Is it instant? Do they tell the tires to move right, then there is a delay, then tell it to go, and a delay, then the video feed comes back of them doing it, and they make adjustments

How does that work

*I seem to recall it being a roughly 21 minute "one way lag time"

You could Google the distance from Earth to Mars and do the math, if you're so inclined.

No inclination in the least,my good&noble forum fellow, whatever

131,000,000 miles ÷ 186,000 mps ÷ 60 seconds = roughly 11 minutes.

Copy, tho, who sez' which radio wavelength frequency is booking on at light speed?

They all are, I believe. Radio waves are part of the electromagnetic spectrum.
