                                       (Answers for Grades 4 and 5)


                               PART 1: THE DAWN OF THE SPACE AGE

 1. A step-rocket that separated into two parts after being launched

 2. The transistorized descendents of this machine would in later years guide spacecraft to the moon, the
    planets, and the vast emptiness of space beyond our solar system.

 3. The Soviet Union launched the first man-made Earth satellite, Sputnik I. As a result, politicians,
    scientists, and educators called for a major U.S. initiative to regain superiority in missile development
    and space technology.

 4. The invention of the first digital computer, UNIVAC, made space exploration possible.

 5. The Space Race began.

 6. The United States and the Soviet Union participated in the Space Race.

 7. Three months and twenty-seven days passed between the launch of Sputnik and when America
    launched its first satellite.

 8. Explorer I was the name of the first satellite launched by the United States.

 9. The Soviet Union put the first man into space. His name was Yuri Gargarin.

10. The first American to orbit Earth was Lt. Colonel John Glenn.

11. Mercury Capsule Friendship 7 was the name of the spacecraft used by John Glenn to orbit the Earth.

12. How much time passed between when the first Russian and the first American orbited Earth?
    (Calculate this yourself.)

13. The Soviet Union made the each step first and the United States followed soon afterwards. This
    shows that the United States was very competitive with the Soviet Union. It also shows that the
    United States was already planning each step even though the Russians did each step first. They
    would never have been able to follow so closely to the Russians if they weren’t already working on it.

14. The name of the first space program started by NASA was Project Mercury.

15. It accomplished six successful manned space flights.

16. Its purpose was exploration of the moon and the operation of Skylab--the first American space station.

17. The event that ended the “Space Race” was when the United States put a man on the moon before the
    Russians did.

18. The Lunar Module Eagle landed on the Moon in the Sea of Tranquility.
                                      PART 2: BEYOND THE MOON

 1. Mariner 2 was the first U.S. spacecraft to fly past Venus and enter a solar orbit.

 2. December 14, 1962

 3. The first U.S. spacecraft to fly by Mars was the Mariner 4. It reached Mars on July 14, 1965.

 4. We learned that Mars has a thin atmosphere composed of CO2 in the range of 5-10 mbar and has a
    small intrinsic magnetic field.

 5. The fist U.S. spacecraft to enter into an orbit around a planet other than the Moon was Mariner 9.

 6. It sent back the first hi-resolution images of the moon Phobos and Deimos. The images showed river and
    channel-like features on the surface of the planet.

 7. The Viking One's lander was the first U.S. spacecraft to land on the Mars' surface.

 8. Pioneer 10, Pioneer 11, Voyager, Voyager 2, Ulysses, and Galileo

 9. It sent information concerning the atmosphere and surface of Saturn’s moon, Titan.

10. Voyager 2 flew by Uranus on January 24, 1986 ad Neptune on August 24, 1989.

11. We are presently using the Space Shuttle and the International Space Station to do work in space.

12. The X-33 and the X-34 have been designed to eventually replace the space shuttles.

13. Student Opinion. Possible answers include: missions to Mars, space travel by people other than

14. Answers may vary. A possible answer is: the Space Race spurred both countries to work harder to
    invent new technology so they could be better than the other country. Without this competitive drive, it
    would have been longer before new technology was invented and the exploration of space would not
    have reached the levels it did as quickly.
