20 основных вопросов:
- Which invention is basic to all rockets that reach outer space?
- The technique of ‘spin stabilization’, to improve rocket accuracy or power was developed by…
- Goddard was interested in rockets reaching higher altitudes. Which of his developments became the forerunner of a whole new era in rocket flight?
- What Was Sputnik 1st major accomplishment?
- Which Russian spacecraft was the first to fly past the moon?
- The U. S. had 3 separate projects to gather information about the moon. What was the name of the project that would take color photographs of the moon?
- What was the name of the first American to orbit the Earth in a small capsule?
- What is the name of the first space station?
- The gravitational force on a satellite changes with the height it is above a planet. What must the satellite control to maintain it circular orbit around the planet?
- In order for a rocket to leave Earth’s gravitational pull and travel out into deep space it must reach its:
- When the rocket leaves the Earth and travels into deep space, its flight path is controlled by what Law(s)?
- In a rocket, what is the purpose of the nozzle?
- Around what ‘point’ will an unstable rocket tumble?
- During a rocket flight, movement in which axis will not affect its flight path?
- What does a ‘Gimbaled Nozzle do when a rocket takes off?
- Why should the center of pressure be towards the rocket’s tail for the rocket to fly straight?
- Who was the first American to ride up to space?
- Over the many years of Goddard’s experiments, he developed…
- To shift the center of mass (CM) of a rocket forward, one needs to add weight to the nose, install lighter fins, and make the rocket shorter.
- Which motor has a lower total impulse for an I class motor?

5 дополнительных вопросов:
- This hot shot pilot rigged up a six iron and took a one-handed swing at a golf ball on the moon. Miles and miles and miles, he announced in satisfaction. Watching the ball fly slow-motion over the moon’s dusty craters. Who was the sportsman?
- Three days before liftoff, this astronaut turned on his car radio and caught a news story in which NASA announced that he had been pulled from his first spaceflight because he had been exposed to German measles. Who was the grounded flier?
- Refer to the diagram at right. An object in space that is near another object is influenced by the gravitational field of that object. Which path in the diagram represents Moon’s actual motion when influenced by Earth’s gravity?
- In addition to carrying out the first major science experiments of the Apollo moon program, these astronauts encountered an object from another world – Earth. Who was on the Surveyor 3 salvage crew?
- Two astronauts on the lunar surface were loading up their moon buggy with tools and equipment when a hammer in the commander’s spacesuit brushed against the fender, ripping half of it off. Oh, you won’t believe it, he radioed to Mission Control. There goes a fender. Whose driving record gets the points?
