Astronauts are currently training on Earth for future missions to Mars. To prepare for the planetary science work they’ll conduct on Mars, they first study satellite imagery. This enables them to understand the planet’s geological history and determine which areas are worthy of further exploration. The astronauts then train in geology, during practice missions on Earth, so they’ll be prepared to identify scientific discoveries on Mars.
In this playlist, students will discover the complex geology of Planet Earth through the training experiences of these astronauts. Students will first learn how to identify notable features using satellite imagery, then they will engage in hands-on activities that will give them an understanding of the forces that shape geological history.
