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

• Valentina Tereshkova

• Sally Ride

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

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

• microscope

• telescope

• hand lens

• camera

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

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.

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
