Which of these is the BEST reason for exercising on space flights?

• to increase strength for moving around in the cabin

• to keep from becoming overweight on a space mission

• to minimize the loss of muscle mass due to microgravity

• to ensure that bodily fluids do not tend to collect in the feet

Why is a spacesuit inflated like a balloon?

• to simulate the air pressure of Earth

• to help astronauts float in outer space

• to protect astronauts from solar radiation

• to provide an oxygen supply for breathing

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.

The instrument shown is used by astronomers to collect incoming microwaves.

What is the name of this instrument?

• space probe

• solar collector

• radio telescope

• orbiting satellite

Which of the following can only be seen with a telescope?

• the moon-like phases of Venus

• the phases of Earth’s moon

• a lunar eclipse

• a solar eclipse

As humans travel in space, which gas is provided in the atmosphere of the spacecraft and which gas is removed from the atmosphere of the spacecraft?

• Oxygen is provided. Carbon dioxide is removed.

• Carbon dioxide is provided. Oxygen is removed.

• Carbon dioxide is provided. Nitrogen is removed.

• Sir Isaac Newton

Some scientists study images of very distant celestial bodies. Where is the BEST location for the types of telescopes that can provide the scientists with the clearest images?

• at sea level

• in outer space

• on mountain tops

• at higher latitudes

What scientific observation did Edwin Hubble use to determine distances between galaxies?

• As the light source passes Earth, the wavelength increases as the frequency increases.

• As the light source moves toward Earth, the wavelength decreases as the frequency increases.

• As the light source moves away from Earth, the wavelength increases as the frequency decreases.

• As the light source affects the gravity of Earth, the wavelength decreases as the frequency decreases.
