  1. Oxygen, Water, Food, Shelter, Body Protection, Medicine/Supplies Introduction to the Mission What resources would we need for space exploration to sustain life? I Can: Describe the needs of human as they travel to and survive on another planet.

  2. Vocabulary Mission Astronaut Habit-able Colony

  3. Perseverance Landing https://www.youtube.com/watch?v=4czjS9h4Fpg

  4. Warm-up Do you think we should travel into outer space? Do you think we could survive on another planet? Why or Why not?

  5. Humans on Mars https://aacps.discoveryeducation.com/learn/videos/70f9c8d9-34e7-4732-8c5b-2b48fc5782b3/

  6. What are the Goals? Which goals? Will there resources (food, water, shelter, air, medicine, and a place to maintain skeletal/muscular health). Return to Earth safely!

  7. Graded Assignment Quick Write (from Warm-up): Do you think we should travel into outer space? Do you think we could survive on another planet?

  8. Reading: There is less water on Mars compared to Earth. Most of the water known is in the cryosphere (permafrost and polar caps). There is no liquid water. There is only a small amount of water vapor in the thin atmosphere. The conditions on the planet's surface do not support the long-term existence of liquid water. The average atmospheric pressure and temperature are far too low, which freezes water. However, it seems Mars once had liquid water flowing on the surface. This would make large areas like Earth's oceans. There are a number of signs of water on or under the surface, now or in the distant past. These include stream beds, polar caps, spectroscopic measurement, eroded craters, there are minerals which are often formed when there is liquid water. The Mars flybys such as Viking, Mars Odyssey, Mars Global Surveyor, Mars Express, and the Mars Reconnaissance Orbiter had cameras. They took pictures of what seem to be ancient lakes, ancient river valleys, and widespread glaciation. Does Mars have water? Notes: 1. 2. Polar Ice Cap on Mars.

  9. Reading: The Martian atmosphere is composed primarily of carbon dioxide. Windstorms, some of which can cover the entire planet, are common on the red planet, lifting rust-colored dust well up into the atmosphere encircling the entire globe. Although water in Mars' atmosphere is only about 1/1000th of the Earth's, enough water vapor exists that thin, wispy clouds are formed in the upper layers of the Martian atmosphere as well as around mountain peaks. No precipitation falls however. At the Viking II Lander site, frost covered the ground each winter. Seasons do exist on Mars, as the planet tilts on its axis about 25 degrees. White caps of water ice and carbon dioxide ice shrink and grow with the progression of winter and summer at the poles. Evidence of climatic cycles exists, as water ice is formed in layers with dust between them. In addition, features near the south pole may have been produced by glaciers which are no longer present. In general, Mars has highly variable weather and is often cloudy. The planet swings from being warm and dusty to cloudy and cold. Mars long ago was likely a warmer, wetter planet with a thicker atmosphere, able to sustain oceans or seas Notes: 1. 2. Question: Does Mars have weather? June 2018 - Curiosity Rover

  10. Reading: On Earth, the main physical weathering processes are frost weathering (sleet, hail and snow), salt weathering (waves), rain weathering and drying for the Sun. On Mars, dunes have formed, and there are small abrasions (scars) on exposed rocks. Some of the landforms present on Mars’s surface also suggest that chemical weathering has taken place. On Mars, sand dunes have formed, and there are small abrasions (scars) on exposed rocks. (See photo below.) Photos from the rovers show that many of the planet’s surface features could have been formed by types of weathering, erosion and deposition processes common on Earth. 2005 Notes: 1. 2. Question: Does Mars have the geological processes of Weathering, Erosion, and Deposition? Polar Ice Cap Dunes

  11. Summary: Summarize your notes on Mars in 2 to 3 COMPLETE statements (capital letters, spell check and punctuation) in the space provided.

  12. Small Groups Is it Habitable? Mercury, Venus, Mars Share your information with Whole Group

  13. Small Group Activity - Week 1

  14. Every student will open and complete slide 3 to turn in. • Choose one team spokesperson to present this in each breakout room. • Your planet to research is your breakout group number in the upper left corner. • 1 - Mercury • 2 - Venus • 3 - Mars • Utilize your resources to answer the questions - Google, DiscoveryEd,National Geographic, etc • HELP YOUR TEAM! Join the discussion and participate. Directions
