The discovery of water on mars is perhaps another step towards the existence of life on the red planet. It is indeed a great milestone achieved by NASA. Scientists are continuously trying to explore great things and putting efforts to find sustainability of life on other planets.

Here are a few things that you should know about the discovery and what this means for scientists and the human race.

1. Around 4 billion years ago, Mars had flowing water and dense atmosphere but Mars lost its atmosphere and became a dry planet.

2. With the loss of atmospheric pressure, the existence of water became chemically unstable on the surface. It was believed that Mars atmospheric pressure was one-tenth of the earth’s pressure.

4. The 2002 Mars Odyssey Mission by NASA discovered signs of hydrogen (in the form of water) around the south pole of Mars. This was a hypothesis in 2002, but it was confirmed, 5 years later, during Mars Phoenix Mission that water exists in the form of ice after they found huge deposits of ice near the south pole.

5. The discovery of liquid water can have significant benefits to the mankind – it will make the Mars mission easier and cheaper and a possibility of life. As the life on the earth is associated with water. It doesn’t mean that life exists on Mars, but it also increases the possibility of life on the red planet.

6. What this means for scientists is that the liquid water can be converted to oxygen which can be used for return trips thereby reducing the cost of the missions.

7. The objective of the next Mars Mission which is scheduled for a launch in 2020 will be to separate oxygen from water which will eventually make temporary stays for humans possible on the red planet.
