Space Exploration

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.

Which spacecraft was the first to leave the Solar System?

• Voyager 1

• Voyager 2

• Pioneer 10

• New Horizons

Which mission first successfully landed humans on the Moon?

• Apollo 11

• Voyager 1

• Mars Rover Perseverance

• Galileo

Who was the first man on the Moon?

• Buzz Aldrin

• Mike Collins

• John Glenn

• Neil Armstrong

Plan a NASA scientific mission to Mars. Consider the objectives, the equipment needed, the potential challenges, and the benefits of the mission.

• Send a robot to collect soil samples, study potential for life, face challenges like dust storms, benefit by understanding if humans can live on Mars.

• Send a telescope to Mars to observe Earth from a distance, face challenges like light pollution, benefit by getting clearer images of space.

• Send a manned mission to explore the deep seas of Mars, face challenges like underwater navigation, benefit by discovering new marine species.

• Send a satellite to orbit Mars to play music, face challenges like signal transmission, benefit by entertaining astronauts on Mars.

Answer explanation

Send a robot to collect soil samples, study potential for life, face challenges like dust storms, benefit by understanding if humans can live on Mars.

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
