Questions and Answers
- 1.
A large artificial satellite on which people can live and work for long periods.
- A.
Space station
- B.
Space shuttle
- C.
Space probe
- D.
Rovers
Correct Answer
A. Space stationExplanation
A space station is a large artificial satellite designed to accommodate people for extended periods of time, allowing them to live and work in space. It serves as a base for scientific research, experimentation, and observation, as well as a platform for launching and controlling space missions. Unlike space shuttles, which are reusable spacecraft designed for transportation, space stations are stationary and provide a long-term habitation solution. Space probes, on the other hand, are unmanned spacecraft used for exploring celestial bodies, while rovers are robotic vehicles used for surface exploration.Rate this question:
-
- 2.
A spaceccraft that can carry a crew into space, return to Earth, and then be reused for the same purpose.
- A.
Rovers
- B.
Space probe
- C.
Space shuttle
- D.
Space station
Correct Answer
C. Space shuttleExplanation
A space shuttle is a spacecraft that is designed to carry a crew into space, return to Earth, and then be reused for the same purpose. Unlike other options such as rovers, space probes, and space stations, a space shuttle has the capability to transport astronauts and cargo to and from space multiple times, making it a more versatile and cost-effective option for human space exploration missions.Rate this question:
-
- 3.
A spacecraft that has various scientific instruments that can collect data, including visual images, but has no human crew. It has its own power system to produce electricity, a communications system to send and receive signals, and scientific instruments.
- A.
Space station
- B.
Rovers
- C.
Space shuttle
- D.
Space probe
Correct Answer
D. Space probeExplanation
A space probe is a spacecraft that is equipped with scientific instruments to collect data, including visual images, but does not have a human crew. It has its own power system to produce electricity, a communications system to send and receive signals, and is designed for scientific exploration and research. Unlike a space station, which is designed for long-term human habitation, or a space shuttle, which is designed for transporting astronauts and cargo to and from space, a space probe is specifically designed for scientific exploration and data collection. Rovers, on the other hand, are robotic vehicles that are used to explore the surface of celestial bodies like planets or moons. Therefore, the best fit for the given description is a space probe.Rate this question:
-
- 4.
Small robots that can move about on the surface of a planet or moon.
- A.
Space shuttle
- B.
Space stations
- C.
Rovers
- D.
Lunar orbiter
Correct Answer
C. RoversExplanation
Rovers are small robots designed to move on the surface of planets or moons. They are commonly used in space exploration missions to gather data and perform various tasks. Unlike space shuttles and space stations, which are vehicles or structures used for transportation and habitation in space, rovers are specifically built for surface exploration. Lunar orbiters, on the other hand, are spacecraft that orbit the moon and capture images or collect data from a distance. Therefore, rovers are the most suitable option for small robots that can move about on the surface of a planet or moon.Rate this question:

A feeling of weightless that astronauts experience in space.
- A.
Vacuum
- B.
Microgravity
- C.
Law of Action and Reaction
- D.
Orbital fluctuation
Correct Answer
B. MicrogravityExplanation
Microgravity refers to the condition in which the force of gravity is greatly reduced, resulting in a feeling of weightlessness. This is experienced by astronauts in space due to the absence of gravitational pull from Earth. In microgravity, objects and individuals float freely and do not experience the normal downward force. This term accurately describes the feeling of weightlessness that astronauts experience in space.Rate this question:

A device that expels gas in one direction to move in the opposite direction.
- A.
Satellite
- B.
Rocket
- C.
Probe
- D.
Vacuum
Correct Answer
B. RocketExplanation
A rocket is a device that expels gas in one direction to move in the opposite direction. Rockets work on the principle of action and reaction, where the expulsion of gas creates a thrust that propels the rocket forward. This makes rocket the correct answer as it perfectly fits the given definition. Satellites, probes, and vacuums do not expel gas to create propulsion, so they do not match the given definition.Rate this question:
-
- 16.
For every force, or action, there is an equal or opposite force, or reaction. This is the __________________.
Correct Answer
Law of Action/Reaction Law of action/reaction Law of Action and Reaction Law of action and reaction Law of Action or ReactionExplanation
The given answer, "Law of Action/Reaction", is correct because it accurately describes the principle that for every force or action, there is an equal and opposite force or reaction. This principle is known as Newton's Third Law of Motion, which states that the forces between two objects are always equal in magnitude and opposite in direction.Rate this question:

Name one of the challenges of space or conditions that differ from Earth.
Correct Answer
microgravity vacuum weightlessness high temperatures health problemsExplanation
The challenges of space or conditions that differ from Earth include microgravity, vacuum, weightlessness, high temperatures, and health problems. In space, the force of gravity is significantly reduced, resulting in microgravity and weightlessness. The vacuum of space lacks air and atmospheric pressure. High temperatures can be experienced due to the extreme conditions in space. Additionally, astronauts may face health problems such as bone and muscle loss, radiation exposure, and psychological effects due to long-duration space missions.Rate this question:

To fly beyond a planet's gravitational pull, a spacecraft must reach
- A.
Velocity
- B.
Orbital velocity
- C.
Escape velocity
- D.
Geostationary orbit
Correct Answer
C. Escape velocityExplanation
In order for a spacecraft to fly beyond a planet's gravitational pull, it must reach escape velocity. Escape velocity is the minimum velocity required for an object to overcome the gravitational pull of a celestial body and escape into space. This velocity depends on the mass and radius of the planet. If a spacecraft reaches escape velocity, it has enough energy to break free from the planet's gravitational field and continue its journey into space. Orbital velocity is the velocity required for an object to stay in a stable orbit around a planet, while geostationary orbit refers to a specific type of orbit where a satellite stays fixed above a particular location on Earth's equator.Rate this question:

A satellite in geosynchronous orbit revolves around the Earth once each
- A.
Hour
- B.
Month
- C.
Day
- D.
Week
Correct Answer
A. HourExplanation
A satellite in geosynchronous orbit revolves around the Earth once each hour. This means that the satellite takes exactly one hour to complete one orbit around the Earth. This type of orbit is achieved when the satellite's orbital period matches the Earth's rotation period, resulting in the satellite appearing to remain stationary in the sky relative to a fixed point on Earth's surface.Rate this question:
