What Do You Know About Spaceflight? - Quiz

Vehicles that are capable of controlling their trajectory are known as spacecrafts. The flight of spacecrafts(with or without humans on board) into the space is known as spaceflight. Examples include : satellites in orbit around Earth, space probes that leave Earth orbit, and so on.


Questions and Answers
  • 1. 

    A space flight typically begins with what? 

    • A.

      An escape velocity

    • B.

      Gravity from celestial body

    • C.

      A rocket launch

    • D.

      Jet propulsion

    Correct Answer
    C. A rocket launch
    Explanation
    A space flight typically begins with a rocket launch because rockets are the primary means of propelling spacecraft into space. Rockets generate enough thrust to overcome Earth's gravitational pull and reach the necessary escape velocity to enter space. Once the rocket is launched, it carries the spacecraft and its payload into space, where it can then maneuver and travel to its intended destination.

    All spaceflight activities without the presence of human are known as what? 

    • A.

      Empty spaceflight

    • B.

      Robotic spaceflight

    • C.

      Manned spaceflight

    • D.

      Unmanned spaceflight

    Correct Answer
    D. Unmanned spaceflight
    Explanation
    Unmanned spaceflight refers to all spaceflight activities that are conducted without the presence of humans. This includes missions and explorations carried out by robotic spacecraft, such as satellites and probes. These unmanned missions are crucial for gathering scientific data, conducting experiments, and exploring distant celestial bodies. Manned spaceflight, on the other hand, involves human astronauts traveling and working in space. Therefore, the correct answer is unmanned spaceflight.

  • 3. 

    The following are the applications of spacecrafts except 

    • A.

      Road transportation

    • B.

      Space exploration

    • C.

      Space tourism

    • D.

      Satellite television

    Correct Answer
    A. Road transportation
    Explanation
    Spacecrafts are vehicles designed for travel and exploration in outer space. They are not used for road transportation as they are specifically designed to operate in the vacuum of space, not on terrestrial roads. Spacecrafts are used for space exploration, which involves sending probes, satellites, and manned missions to study celestial bodies and gather scientific data. Space tourism is another application, where spacecrafts are used to transport tourists to space for recreational purposes. Satellite television is also made possible by spacecrafts, as they are used to transmit television signals from space to Earth. However, road transportation is not a function of spacecrafts.

    The non-commercial uses of spaceflight include the following except 

    • A.

      Earth observation satellites

    • B.

      Space tourism

    • C.

      Space observatories

    • D.

      Re-connaissance satellites

    Correct Answer
    B. Space tourism
    Explanation
    Space tourism is the only option listed that does not involve non-commercial uses of spaceflight. Earth observation satellites are used to gather data about the Earth's surface, Space observatories are used for astronomical research, and Re-connaissance satellites are used for military or intelligence purposes. However, space tourism refers to the practice of traveling to space for recreational purposes, which is a commercial use of spaceflight.

    Who was the first American in orbit? 

    • A.

      Yuri Gagarin

    • B.

      Neil Armstrong

    • C.

      Buzz Aldrin

    • D.

      John Glenn

    Correct Answer
    D. John Glenn
    Explanation
    John Glenn was the first American in orbit. This is because Yuri Gagarin was the first human to orbit Earth, but he was a Soviet cosmonaut, not an American. Neil Armstrong and Buzz Aldrin were astronauts, but they were part of the Apollo 11 mission that landed on the moon, not in orbit. Therefore, the correct answer is John Glenn.

    The record for the longest continuous time spent in space is held by who? 

    • A.

      Valeri Polyakov

    • B.

      Eldar Matveyev

    • C.

      Rafik Yusupov

    • D.

      Avdei Yusupov

    Correct Answer
    A. Valeri Polyakov
    Explanation
    Valeri Polyakov holds the record for the longest continuous time spent in space.

    The only means currently capable of reaching orbital or beyond is through the use of what? 

    • A.

      Power bikes

    • B.

      Helicopter

    • C.

      Rockets

    • D.

      Aeroplanes

    Correct Answer
    C. Rockets
    Explanation
    Rockets are the only means currently capable of reaching orbital or beyond. While power bikes, helicopters, and airplanes are all capable of flying, they do not have the necessary propulsion systems to reach the speeds and altitudes required for orbital or interplanetary travel. Rockets, on the other hand, are specifically designed to generate enough thrust to overcome Earth's gravity and propel spacecraft into space. They use a combination of fuel and oxidizer to create a controlled explosion, producing a powerful thrust that propels the rocket and its payload into orbit or beyond.

    The record for the longest non-continuous time spent in space belongs to who? 

    • A.

      Lucas Golubov

    • B.

      Sergei Krikalev

    • C.

      Constantine Mironov

    • D.

      Emmanuel Pirogov

    Correct Answer
    B. Sergei Krikalev
    Explanation
    Sergei Krikalev holds the record for the longest non-continuous time spent in space. The other options provided, Lucas Golubov, Constantine Mironov, and Emmanuel Pirogov, are not known for their accomplishments in space.

    The study of spacecraft trajectories is known as 

    • A.

      Dynamics

    • B.

      Astronomy

    • C.

      Astrodynamics

    • D.

      Aerodynamics

    Correct Answer
    C. Astrodynamics
    Explanation
    Astrodynamics is the correct answer because it specifically refers to the study of spacecraft trajectories. Dynamics is a broader term that encompasses the study of motion and forces in general, while astronomy focuses on the study of celestial objects. Aerodynamics, on the other hand, deals with the study of the motion of air and other gases. Therefore, Astrodynamics is the most appropriate term to describe the study of spacecraft trajectories.

    The first animals to be sent to space were

    • A.

      Monkeys

    • B.

      Fruit flies

    • C.

      Dogs

    • D.

      Rats

    Correct Answer
    B. Fruit flies
    Explanation
    The correct answer is fruit flies because they were the first animals to be sent to space. Fruit flies were chosen for their small size, short lifespan, and ability to reproduce quickly, making them ideal for studying the effects of space travel on living organisms. These experiments helped scientists understand the impact of space travel on biological systems and paved the way for future missions involving larger animals and eventually humans.
