I think that they found ice. Also, some of the geographic features suggest that there was once a river there.
Several features on Mars suggest the possibility of liquid water, including recurring slope lineae (RSL), which are dark streaks that appear during warmer seasons and may indicate briny water flow. Additionally, the presence of ancient riverbeds, lake basins, and minerals like clays and sulfates that form in water further support the idea that liquid water once existed on the planet's surface. Recent observations also suggest the potential for subsurface water reservoirs, which could harbor liquid water even under current harsh conditions.
Presence of liquid water on the planet, indicating potential for habitability. Detection of organic molecules, suggesting the possibility of past or present life. Geological features resembling those on Earth where life thrives. Survival of extremophiles on Earth in extreme conditions, raising the possibility of similar life forms on Mars.
The discover of water on Mars has some significance to scientists. Even though the planet is very hot due to its proximity to the Sun, the presence of water signifies the possibility of life.
Salty water has a lower freezing point than pure water. So, very salty water may have a chance of being liquid on Mars. However there seems to be no liquid water on Mars.
Scientists and space agencies such as NASA are actively researching the possibility of microbial life on Mars due to the presence of water and potential habitable conditions in the past. However, as of now, there is no definitive evidence of current life on Mars.
Features such as dried-up river channels, lake beds, and mineral deposits that require water to form suggest the possibility of liquid water on Mars in the past. Recent discoveries of recurring slope lineae (dark streaks on Martian slopes) also indicate that liquid water may exist on the planet's surface today.
Gullies and streamlike channels
The presence of hydrated minerals, recurring slope lineae (dark streaks on slopes), and the discovery of ancient river valleys and lakebeds suggest that liquid water may have existed on Mars in the past. Additionally, recent observations of briny water flowing on the surface during specific seasons further support the possibility of liquid water on Mars.
Dry riverbeds and sedimentary substances that can only be formed in a liquid environment.

Scientists would like to know if there is water on mars because if it is there the planet has the possibility of sustaining life.
the phoenix lander is currently digging into ice under the surface to see if there actually is liquid water on mars.
We don't know if there was life on Mars, but we have found evidence of water in a permafrost layer and at the poles, plus other indicators. There is the possibility that there was once life on Mars, but right now that's all it is, a possibility.

mars north polar cap is sposed to have water on it geographical features simalar to ones on earth leading to further proof that Mars has or had water on it
The discover of water on Mars has some significance to scientists. Even though the planet is very hot due to its proximity to the Sun, the presence of water signifies the possibility of life.
Indications that suggest water existed on Mars include dried-up river channels, alluvial fans, ancient shorelines, mineral deposits formed in water-rich environments, and the presence of hydrated minerals like clay. Additionally, satellite images and rover data have revealed features such as gullies, deltas, and sediment layers that point to past water flow on Mars.
