Asteroids – Unit 3: Astrobiology
Lessons in this unit address the question:
How can what we know about life on Earth guide us to other places in the solar system where life may exist now or may have existed in the past?
Lesson Guiding Questions:
Lesson 1: How do the four major planetary systems (atmosphere, geosphere, hydrosphere, and biosphere) influence and control each other here on Earth?
Lesson 2: What can measuring the amount and forms of carbon in an environment tell us about the life there?
Lesson 3: What can we learn from extreme environments on Earth to plan where and how to look for life on other planetary bodies?
Lesson 4: How does NASA look for evidence of past or present life?
