31. Foldables Exploring Space Make the following Foldable to help identify what you already know, what you want to know, and what you learned about exploring space.

32. Foldables Fold a vertical sheet of paper from side to side, with the front edge about 1.25 cm shorter than the back.

33. Foldables Turn lengthwise and fold into thirds.

34. Foldables Unfold and cut only the top layer along both folds to make three tabs. Label each tab.

35. Foldables Identify Questions Before you read the chapter, write what you already know about exploring space under the left tab of your Foldable, and write questions about what you’d like to know under the center tab. After you read the chapter, list what you learned under the right tab.

36. Reviewing Main Ideas 1 Radiation from Space • The arrangement of electromagnetic waves according to their wavelengths is the electromagnetic spectrum. • Optical telescopes produce magnified images of objects. • Radio telescopes collect and record radio waves given off by some space objects.

37. Reviewing Main Ideas 2 Early Space Missions • A satellite is an object that revolves around another object. The moons of planets are natural satellites. Artificial satellites are those made by people. • A space probe travels into the solar system, gathers data, and sends them back to Earth. • American piloted space programs included the Gemini, Mercury, and Apollo Projects.

38. Reviewing Main Ideas 3 Current and Future Space Missions • Space stations provide the opportunity to conduct research not possible on Earth. The International Space Station is being constructed in space with the cooperation of more than a dozen nations. • The space shuttle is a reusable spacecraft that carries astronauts, satellites, and other cargo to and from space.

39. Reviewing Main Ideas 3 Current and Future Space Missions • Space technology is used to solve problems on Earth, too. Advances in engineering related to space travel have aided medicine, environmental sciences, and other fields.

42. Chapter Review Question 2 Which type of optical telescope uses a curved mirror to direct light? • radio • B. reflecting • C. refracting • D. reverberating

43. Chapter Review Answer • The answer is B. Light is reflected off the • concave mirror and forms an image in the focal • point.

44. Chapter Review Question 3 • Which of the following statements is NOT true • of the Hubble Space Telescope? • After it was launched it could not be repaired. • B. It has viewed other galaxies. • C. It is located outside Earth’s atmosphere. • D. It was launched by a space shuttle

45. Chapter Review Answer • The answer is A. In 1993, astronauts repaired • Hubble by installing additional mirrors to • correct images obtained by a faulty mirror.

46. Chapter Review Question 4 • What was the first artificial satellite? A. Galileo B. Hubble C. Perseid D. Sputnik

47. Chapter Review Answer The answer is D. Sputnik I was launched in 1957 by the former Soviet Union.

48. Chapter Review Question 5 How does a space probe differ from a satellite? Answer Satellites orbit Earth; space probes travel into the solar system.
