The Exploration and Colonization of Mars: Why Mars? Why Humans? | Dr. Joel Levine | TEDxRVA

We get oxygen from these photosynthetic plants. Oxygen breaks down with solar radiation (small amounts) and forms a gas called ozone that protects the Earth's surface from deadly biological radiation from the sun, called ultraviolet radiation. as soon as we have oxygen in the atmosphere. When we have oxygen in the atmosphere and ozone. The atmosphere is thick enough because we have emitted a lot of carbon dioxide and water vapor and liquid water can form on the planet and be geologically stable. time scales This is the artist's conception of Mars today This is Mars after terraforming or space engineering A while ago I watched a historical movie.

We're Not Supposed to Give It Publicity: "The Theory of Everything" Stephen's Autobiography. Hawking One of the greatest astronomical thinkers in the world and in history This is a quote: "I believe that the human race has no future if it does not go to space." And let me show you how to go to Mars and how to do it. Do astronauts return to Earth? If I can show you the last video, please, the last video. This is a test in December of last year of the Orion space capsule. This is the one that will bring

humans

to Mars.

Real Image This is what really happened on December 5th. Then, as soon as it moves away from Earth, it will encounter a transport vehicle that we have already put into orbit around Earth. Surface of Mars It's a nine-month journey, and this will enter the Martian atmosphere, land on the surface of Mars, and then once we're on the surface of Mars, the astronauts will look for signs of life. In search of fossils, we will start digging to find the history, the climate of the Earth and then 500 days later, we will return the astronauts to Earth. This is a real image.

This is under the drawing board. It will probably be between 2033 and 2039 when we do it. Thank you (Applause).
