The space shuttle carries astronauts back and forth between Earth and the International Space Station in orbit around our planet. What feature is necessary for the space shuttle to perform its function? The space shuttle must have -
sufficient mass to provide gravity equal to that of Earth.
powerful engines to escape the pull of Earth's gravity.
enough food for the astronauts to eat for several years.
adequate space in which the astronauts can float freely.
Some scientists are planning a manned space mission to a rocky planet slightly farther from the Sun than Earth. To which planet are they sending astronauts?
Mercury
Venus
Mars
Jupiter
Astronauts walking in space must wear space suits. The space suits provide all of the following EXCEPT -
oxygen.
gravity.
protection.
communication.
What science tool advanced space exploration by allowing humans to see better and farther into space?
Microscope
Telescope
Camera

The International Space Station (ISS) is a huge science laboratory that orbits Earth every 92 minutes. Experiments on board the ISS can help scientists learn -
why Earth rotates on its axis every day.
what substances are found in moon dust.
when the first green plants appeared on Earth.
how to solve problems of living in space.
What is an important requirement for a manned spacecraft traveling through space?
The ability to create its own gravity
Bright lights to see where it's going
A device for growing food for humans
A supply of oxygen for the astronauts
Which of the following is the first challenge that had to be overcome by rockets in order for humans to explore space? First, rockets needed -
a place in which the astronauts could sit.
a way to return to Earth's surface.
enough thrust to overcome Earth's gravity.
landing gear that worked on another planet.
With our current technology, travel to the closest star in another solar system is not possible for a human crew due to what limitation?
Inability to store food and water for long periods of time.
Lack of data about the many objects found in space.
Absence of light and energy in the far reaches of space.
Relatively short human life spans and slow travel speeds.
Which of the following celestial bodies of the Solar System have humans visited?
the Moon
Mars
Venus
Saturn
Who was the first human to walk on the Moon?
Yuri A. Gagarin
Neil Armstrong

collect rocks and soil samples.
communicate with people on Earth.
transport equipment to the International Space Station.
provide areas for conducting experiments.
What is the primary purpose of the International Space Station (ISS) in terms of scientific research?
To serve as a launch pad for missions to Mars
To conduct experiments in microgravity
To monitor Earth's weather patterns
To mine asteroids for resources
Which of the following is a major challenge astronauts face when living on the International Space Station for extended periods?
