Hi, I'm Grant with more science news you can use. 00:00:00
Well, I'm all packed to go to Mars. 00:00:06
To Mars? Mars is about 55 million miles from Earth. 00:00:09
That would be 89 million kilometers. It would take me years to get there. 00:00:14
Actually, it would take you about six or seven months. 00:00:18
But you have to take a bioregenerative system to provide food, water, and air just to keep you alive. 00:00:22
Don't forget that in space, radiation will also be a problem 00:00:29
because you won't have the Earth's atmosphere and the Earth's magnetic field to protect you. 00:00:34
And what about the spaceship? 00:00:39
You will need a very big one to carry lots of water, dehydrated food, medical equipment, and a big lander 00:00:41
so that you can be the first person to step on Mars. 00:00:48

Until next time, I'm Grant. 00:00:55
Cool space science news you can use. 00:00:57
Hi, I'm Cory with more space science news you can use. 00:01:12
Where can NASA find water on Mars? 00:01:19
I need to know this since I plan to be the first person to step on Mars. 00:01:22
You can be first, after me. 00:01:26
So where's the water? 00:01:28
The Phoenix Mars Lander mission will explore near Mars' north pole. 00:01:30
Scientists believe this part of Mars has soil with lots of water in it. 00:01:34
So this is water I can drink? 00:01:37
No, it's water ice under a thin soil layer. 00:01:40
There may have been an ocean there long ago. 00:01:43
Some water stayed behind and froze when Mars' climate changed. 00:01:45
Will NASA land astronauts in the same area? 00:01:48
Maybe. Phoenix Mars Lander is a big step to help NASA decide where I get to walk first. 00:01:51
After me. 00:01:56
To find out more about Phoenix Mars Lander, check out our website. 00:01:58
Until next time, I'm Cory with cool space science news you can use. 00:02:02
