Space probes are unmanned spacecraft that have helped scientists gather more detailed information about the universe and objects in our solar system. Space probes send back all of the following EXCEPT -

• soil and rocks from the surfaces of planets and moons.

• information about a planet's surface and atmosphere.

• photographs of distant stars and space objects.

• data about the effects of solar winds on planets.

Why is it necessary for astronauts on the International Space Station to generate and recycle oxygen?

• Oxygen provides energy for the station's fuel tanks.

• Oxygen protects the space station from radiation.

• There is not enough oxygen in space to sustain life.

• Oxygen is a by-product of human respiration

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

• Mars

• Venus

• Jupiter

Astronauts walking in space must wear space suits. The space suits provide all of the following EXCEPT -

• oxygen

• gravity

• protection

• communication

Which of the following pieces of equipment helps scientists control spacecraft and analyze data received from space?

• computers

• telescopes

• rockets

• cameras

A space probe, a satellite, and a manned rocket all share what characteristic? They must be able to -

• collect rocks and soil samples.

• communicate with people on Earth.

• transport equipment to the International Space Station.

• provide areas for conducting experiments.

What science tool advanced space exploration by allowing humans to see better and farther into space?

• microscope

• telescope

• hand lens

• camera

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

A tether is a rope-like device that attaches an astronaut to a space vehicle during the time spent outside on a spacewalk. Why is a tether necessary?

• Strong solar winds would blow the astronaut away from the vehicle otherwise.

• Astronauts must remain close to the vehicle to obtain the heat it provides.

• Without a tether, astronauts would float away due to the lack of gravity in space.

• Tethers add just enough weight to the astronaut to keep them in orbit.

What is the most important function of a space suit like the ones astronauts wear when walking in space?

• To give the astronaut freedom of movement in space

• To provide oxygen and protection from radiation

• To make it easy to get in and out of the International Space Station

• To help the astronaut perform experiments in space
