Hi, I'm Zola Vanessa with more science news you can use.

2
00:00:07,000 --> 00:00:11,000
Did you know that NASA's Mars Odyssey spacecraft found lots of water ice on Mars?

3
00:00:11,000 --> 00:00:13,000
How much water did they find?

4
00:00:13,000 --> 00:00:16,000
Scientists believe there's enough water to fill Lake Michigan twice.

5
00:00:16,000 --> 00:00:18,000
Why is finding water important?

6
00:00:18,000 --> 00:00:19,000
All life needs water.

7
00:00:19,000 --> 00:00:24,000
If there's frozen water on Mars, this suggests life may have lived there before.

8
00:00:24,000 --> 00:00:25,000
No kidding!

9
00:00:26,000 --> 00:00:28,000
Water is important because people who travel to Mars

10
00:00:28,000 --> 00:00:33,000
will not have to take extra water, oxygen or fuel for the trip back to Earth.

11
00:00:33,000 --> 00:00:37,000
I can understand how to get water to drink, but oxygen?

12
00:00:37,000 --> 00:00:39,000
Water is made from hydrogen and oxygen.

13
00:00:39,000 --> 00:00:42,000
If you separate hydrogen and oxygen using chemistry,

14
00:00:42,000 --> 00:00:47,000
you can breathe the oxygen and combine the two with other elements on Mars to propel you home.

15
00:00:47,000 --> 00:00:50,000
