Since 1990, the Hubble Space Telescope has been orbiting Earth and sending back images of space for astronomers to view and interpret. What benefit is there to a telescope that orbits Earth?

• Views from outer space telescopes are clearer than those from Earth-based telescopes.

• Earth-based telescopes have a greater range of light detection.

• Human error is reduced by the use of the Hubble telescope.

• The Hubble telescope is used to examine events that cannot be explained.

To which planet do National Aeronautics and Space Administration (NASA) scientists hope to send humans next?

• Mars

• Venus

• Jupiter

• Mercury

In 1957, the first artificial satellite was put into space. By 1969, American astronauts landed on the Moon. What MOST likely helped scientists to be able to go from launching artificial satellites to sending spacecraft to the Moon in just twelve years?

• Scientists discovered a way that rockets could travel at the speed of light.

• Scientists improved instruments that helped calculate the distance to the Moon.

• Scientists improved on the older rockets that were designed by previous engineers.

• Scientists gained information that the gravity of the Moon was less than that of Earth.

Which of these is an unpiloted spacecraft designed to gather information while orbiting planets other than Earth?

• space probe

• space shuttle

• space station

• space telescope

A telescope would be MOST useful in answering which question?

• How do rockets move in space?

• What shape is a human skin cell?

• What is on the surface of the Moon?

• How do worms breathe underground?

The National Aeronautics and Space Administration (NASA) is the agency responsible for the space program in the United States. What was the goal of NASA’s Apollo program?

• to search for life on planets other than Earth

• to land on a planet in another solar system

• to determine the composition of the Sun

• to send a human to land on the Moon

In 1976, the Viking I Lander was sent to Mars to analyze atmospheric gases and soil samples. The Viking I Lander was MOST likely a

• space probe

• space shuttle

• lunar module

• natural satellite
