spying
- 7. why did the us congress establish NASA in 1958? - -b. to put emphasis
on winning the "space race" against the soviet union
- 8. what was the purpose of NASA's mercury and gemini missions in the
1950's and 1960's? - -c. they acted as stepping-stones to landing on the
moon
- 9. what event ended the space race? - -a. neil armstrong became the first
man on the moon on july 20, 1969
- 10. NACA hired five female "compters" in 1935 to _________. - -d. preform
complex calculations so NACA engineers could focus on research
- 11. how did the invention of jet engine technology impact passenger
travel? - -a. it enabled travel at higher speeds
- 12. the mercury 7 astronauts who were selected in 1959 ___________. - -b.
were all men who had served as military test pilots
- 13. why was the swept wing design important in the development - -b.
they delay the formation of shock waves generated by jet engines
, - 14. what made the space shuttle such an advancement in aerospace? - -b.
it was a resuable spacecraft that could carry humans and cargo
- 15. why was the competition between the soviet union and the united
states called the "Space race"? - -a. the united states and the soviet union
were racing for supremacy in spaceflight
- 16. after the cold war ended, what was the relationship between the united
states and the soviet union regarding space exploration? - -d. the united
states and the soviet union started to work together, eventually docking
their aircraft in space
- 17. power and performance were improved in aircraft because of jet
engines, but ________________. - -b. the aircraft designs were greatly
impacted as engineers worked to take full advantage of the increased
performance provided
- 18. fill in the blank: the first operational orbiter to fly in space was the

- 21. how did the development of the world's first jetliner, the boeing 707,
impact society - -the B-707 launched the world into the commercial jet age,
and we became a much more global society. commercial jets made travel
quicker and easier; they expanded the economy by bringing people and
cultures together and allowing for faster trade.
- 22. explain at least two challenges in making an operational jet engine and
jet aircraft. - -it was difficult for engineers to find materials that were
suitable for handing the stress involved in operating a jet engine (mainly
heat and pressure). it was also difficult for them to determine how to
effectively managing the challenges of high altitude flight and high-speed
flight. for example, as a jet aircraft approached the speed of sound,
vibrations caused by shocked waves caused the aircraft to be nearly
uncontrollable. the development of swept wings solved for this problem
- 23. why was the success of the mercury program an important
achievement during the space race? - -mercury was the first program to put
astronauts into space. it perfected techniques to orbit a manned spacecraft
around earth, determined an astronaut's capability to function and live in
