| 0:00.0 | This is CBS High in the World. I'm John Batcher with David Livingston. Dr. Space, this is the |
| 0:09.6 | Space Show Hotel Mars and we're actually on Mars 3.4 billion years ago with Professor |
| 0:16.4 | Alexis Rodriguez who publishes a story about what happened the day the asteroid struck. |
| 0:22.8 | The asteroid that hit the Yucatan Peninsula was estimated between six and nine miles across |
| 0:29.7 | some, maybe his largest 10 miles across and it struck and ended the dinosaurs 65, 66 million |
| 0:36.0 | years ago. This asteroid struck 3.4 billion years ago and we do not know whether it ended |
| 0:43.6 | any life because we're not sure there was life there but the professor is using the word |
| 0:48.3 | habitability to understand the chemical's components of the ocean that dominated the Northern |
| 0:55.6 | hemisphere of Mars. David, you have a question for the professor. Professor with your unlimited |
| 1:01.6 | budget, would you do any exploring on the southern hemisphere of Mars? The southern hemisphere. |
| 1:11.1 | I think that okay with my unlimited budget there is another area that I would love to go and |
| 1:20.7 | explore is more equatorial, subtropical. It's actually in the chaotic terrains of Mars and |
| 1:31.4 | the chaotic terrains are extremely interesting geologic features because they represent |
| 1:40.8 | the largest windows between the groundwater systems and the surface water systems that we know |
| 1:48.8 | of in the entire solar system. Essentially they are zones where the aquifers released the water |
| 1:56.7 | to the surface and produce immense channels that then ended up in the northern plains. |
| 2:06.0 | I would love to go to explore these outlets from these massive groundwater systems on Mars. |
| 2:14.1 | They are as the name suggests like chaotic terrains. They are actually extremely complicated terrains. |
| 2:20.4 | The ocean, back to the Northern hemisphere, the ocean that existed at the day of the event, |
| 2:26.6 | that ocean was fed by aquifers and I found it saying correctly the aquifers were feeding liquid |
| 2:32.2 | water into the surface. These aquifers, what is your explanation for their origin? Are they from |
| 2:40.8 | off-planet events, asteroids, contact with a previous planet? Where did that water come from? |
