the phoenix lander is currently digging into ice under the surface to see if there actually is liquid water on mars.
To see if there was life living on mars...All living things need water so if there was water on mars life could exist no matter how small
No, nobody has yet. Although scientists at NASA are apparently finding evidence of water on this planet.
Astronomers have not yet made any findings regarding the possibility of life on Mars.
I do not think that Mars has any known water at all.
There is a possibility that Mars supports bacterial or microscopic life forms, but nothing complex. And we don't know that there is any life at all on Mars.
Mars doesn't have any water
It had.
We dont know if Mars has any type of water. But we do believe that there is a trace of water somewhere.
With technology getting better everyday the possibility of going to mars could happen any day. So yes I think that it will eventually happen.
Yes, Earth is confirmed to have both water and life (though not extraterrestrial life). As for the other 7 planets, no life has been found as of 2017, and only Mars has evidence of water, though this information could change in the future.
The reason why Mars has no water because its atmosphere is too thin, so the sun vapoured all the water on Mars and it does not have any plants to make it rain there.
