Unit 2 Lesson 4 How Does Technology Help Us Learn About Space? Early Astronomers Early astronomers were limited to observing space with just their eyes. They believed that Earth was the center of the universe. Copyright © Houghton Mifflin Harcourt Publishing Company

Unit 2 Lesson 4 How Does Technology Help Us Learn About Space? Early Astronomers In the 1600s, the telescope was invented. The telescope is a tool that uses lenses to make faraway objects appear closer and larger. Galileo was one of the first astronomers to study space using a telescope. He observed four of Jupiter’s moons. Copyright © Houghton Mifflin Harcourt Publishing Company

Unit 2 Lesson 4 How Does Technology Help Us Learn About Space? Early Astronomers By the 1600s, scientists knew that the sun was the center of the solar system. They also believed that the sun was the center of the universe. At that time, scientists had observed five other planets with telescopes. Copyright © Houghton Mifflin Harcourt Publishing Company

Florida’s Role in Space Unit 2 Lesson 4 How Does Technology Help Us Learn About Space? Florida’s Role in Space The Space Age began in Florida in the early 1960s at Cape Canaveral. Florida’s fair weather makes it a good place to launch rockets. In 1963, the space center was renamed Kennedy Space Center. Copyright © Houghton Mifflin Harcourt Publishing Company

Florida’s Role in Space Unit 2 Lesson 4 How Does Technology Help Us Learn About Space? Florida’s Role in Space Many people work at Kennedy Space Center, and it is an important tourist attraction for Florida. Engineers design and build rockets there. Scientists also study space data there. Copyright © Houghton Mifflin Harcourt Publishing Company

Space Technology in Every Home Unit 2 Lesson 4 How Does Technology Help Us Learn About Space? Space Technology in Every Home Much of the technology used in our homes comes from the space program. Examples include cordless tools, the soles on athletic shoes, nonstick surfaces, beverage coolers, freeze-dried foods, and fire-resistant suit technologies.
