Great quality pictures from the perseverance rover but I see a lot of stone picking needed. The first humans to go there have their work cut out for them.
 
Agreed.

Very good quality!
 
Maybe as practice people can come to my place and pick stones. By the time we actually can get someone to Mars they should have my place pretty much picked clean.
 
Though very little in the atmosphere, there is vast quantities in the Northern Ice cap, and in the carbon dioxide and buried water Ice in the south pole cap. Though it is combined with carbon or hydrogen in both cases, there is no issue about its abundance. There is solid evidence of liquid water as well in more equatorial directions. Even the rocks are oxides of ? Jim
 
Hollywood back lot again? IF there actually was intelligent life on Mars do you think they would be impressed with what they find on earth? They would probably hide from any space ships that landed there.

Seems like a great waste of money to me. I hope they prove me wrong.
 
The Mars rover needs power to send pictures back here. And to take the soil samples with it's probe. There are 2 lithium-ion batteries on Rover. One might suspect the Rover is solar powered. But no. To much Martian dust for solar panels. The battery's get electric power from a a container of plutonium on board which gives off heat as it decays. This heat is converted to electric and stored in the lithium-ion battery's. Seems like a type of nuclear power on a very small scale. Mars rover only needs 110 watts most of the time to keep instruments operating & drive around the planet for exploration. And send outstanding color pictures back to us on Earth.
