About 100 days before,
00:00:15
On another planet ---- the surface of Mars on
00:00:17
Successfully landed a 2-ton SUV (Sports Utility Vehicle, utility vehicle)
00:00:19
The surface of Mars.
00:00:20
This is one of the bots earliest photographs taken
00:00:23
The surface toward the direction of the sharp mountain (Mount Sharp).
00:00:25
For me, to see this picture when
00:00:27
I am excited to almost choking back tears.
00:00:29
Why do we want to Mars, why do we want to detect other planets?
00:00:31
Partly in order to understand ourselves living on a planet,
00:00:32
What we have is what kind of environment?
00:00:34
We live in a magical planet,
00:00:36
However, Mars and the Earth in many ways similar.
00:00:37
Their size is about the same.
00:00:39
The temperature on Mars can be as high as 70 degrees Fahrenheit.
00:00:43
So, Mars and Earth are very similar, but at the same time,
00:00:45
As you know, this is a harsh and barren continent,
00:00:47
You do not see any tree,
00:00:48
Do not see cactus growing,
00:00:49
Also do not see similar signs of life.
00:00:50
Therefore, today I am going to tell you
00:00:51
How we are to reach Mars from Earth,
00:00:54
And why this project is really cool.
00:00:57
A piece of paper.
00:00:58
We know from previous 2004 mission ---
00:01:01
Spirit and Opportunity adventure that,
00:01:01
Mars was once water,
00:01:03
However, the next step is to detect what is it?
00:01:06
We want from a more fundamental point of view
00:01:08
To study the reason for the existence of life,
00:01:12
Knowledge and theory.
00:01:13
Therefore, we need a large number of instruments.
00:01:17
On Earth the whole room can be loaded under laboratory equipment
00:01:19
Put it in a small car.
00:01:22
We have done is these are all reduced to
00:01:23
And I almost heavy,
00:01:25
And put it into the robots,
00:01:27
Roaming weight and you open the car is about the same weight.
00:01:29
Now, the robots on the surface of Mars,
00:01:32
But it was too heavy,
00:01:34
Brought us a special challenge ----
00:01:37
How to make these instruments complement each other, normal operation.
00:01:41
We checked the tools at hand,
00:01:42
What kind of material is capable of landing on Mars?
00:01:43
One method is to use the airbag.
00:01:45
We've also used.
