If there is water on mars, there might be life on mars, and if there is life on mars, that means that humans could survive there as well.
Even if there isn't life on Mars, the water would mean that people would be able to go there and maybe even live there without having to rely on bringing water in space ships.
on its icecaps
it has 78% frozen

That's simple. They could look through a telescope and see some planets near the earth, but not all. Astronauts travel in space and study them.
We can look for it by using these tecniqes. •Seeing it in rocks (meteorites) •Seeing it gravitationally •Seeing it spectroscopically (remote sensing) •Seeing morphological features of it (remote sensing) •Seeing it (remote sensing)
It helps you look far into space. :)
The only object in our solar system other than Earth to have rivers is Titan, Saturn's largest moon. Instead of water, Titan has rivers of liquid methane. Other planets outside of our solar system probably have rivers, but we have only discovered a tiny fraction of these planets and we do not know what their surfaces look like.
well you have the be in a space suit in all planets but earth and other air giveing planets so your neighbor wold look the same in a space suit
All life as we currently know it cannot exist without water (H2O). Scientists look for signs of water when searching for life on other planets.
Liquid water is an indicator that there is probably life present.

what molecule do scientists look for when they are investigsating the possibility of life on other planets
Green and live plants, animals, water, good soil, air

Liquid water. All else is incidental.
Two reasons. (1) Such planets are very dim, from our point of view. Some of the planets in our own Solar System look roughly as bright as the brightest stars; now imagine them at least 100,000 times farther - that would make them 10 billion times dimmer, from our point of view. (2) Such planets are very close to their star - once again, from our point of view, i.e., considering the angular distance.
NASA assumed Mars was once a place with water (rivers and seas). They are searching for water since it is believed "where there is water there could be life."
yes look at mars there are many trenches from erosion
You can look at the map on the thingy by the girl(the academy,dropout one)there u can look at where the planets are or there could be a new one and u can goto it.
They are sending robots to explore other planets where they conduct evperiment to see if the planet can support life.
