What is the primary source of space debris?

  1. Natural meteoroids and asteroids

  2. Abandoned spacecraft and satellites

  3. Rocket boosters and launch vehicle components

  4. All of the above


Correct Option: D
Explanation:

Space debris originates from various sources, including natural meteoroids and asteroids, abandoned spacecraft and satellites, and rocket boosters and launch vehicle components.

How does space debris affect Earth's environment?

  1. It can disrupt satellite communications and GPS systems.

  2. It poses a collision risk to operational spacecraft.

  3. It can cause light pollution and interfere with astronomical observations.

  4. All of the above


Correct Option: D
Explanation:

Space debris can have several negative impacts on Earth's environment, including disrupting satellite communications and GPS systems, posing a collision risk to operational spacecraft, and causing light pollution and interfering with astronomical observations.

What is the Kessler Syndrome?

  1. A theory that suggests a chain reaction of collisions in space, leading to an exponential increase in space debris.

  2. A phenomenon where space debris accumulates in certain orbital regions, creating dense clusters.

  3. A method for removing space debris from orbit using lasers or nets.

  4. A type of spacecraft designed to capture and deorbit space debris.


Correct Option: A
Explanation:

The Kessler Syndrome is a theoretical scenario where the amount of space debris in orbit reaches a critical point, leading to a chain reaction of collisions that exponentially increases the amount of debris.

Which country has the most space debris in orbit?

  1. United States

  2. Russia

  3. China

  4. India


Correct Option: A
Explanation:

The United States has the most space debris in orbit due to its extensive history of space exploration and satellite launches.

What is the average size of a piece of space debris?

  1. Less than 1 centimeter

  2. 1 to 10 centimeters

  3. 10 to 100 centimeters

  4. Greater than 100 centimeters


Correct Option: B
Explanation:

The average size of a piece of space debris is between 1 and 10 centimeters.

How many pieces of space debris are estimated to be in orbit around Earth?

  1. Less than 100,000

  2. 100,000 to 1 million

  3. 1 million to 10 million

  4. More than 10 million


Correct Option: D
Explanation:

Estimates suggest that there are more than 10 million pieces of space debris in orbit around Earth.

What is the primary method for removing space debris from orbit?

  1. Using lasers to vaporize debris

  2. Using nets or harpoons to capture debris

  3. Using spacecraft to deorbit debris

  4. Using natural atmospheric drag to deorbit debris


Correct Option: C
Explanation:

The primary method for removing space debris from orbit is using spacecraft to deorbit the debris, either by bringing it back to Earth or sending it to a higher orbit where it will eventually burn up in the atmosphere.

What is the name of the first mission dedicated to removing space debris from orbit?

  1. RemoveDEBRIS

  2. e.Deorbit

  3. Space Debris Removal

  4. ClearSpace-1


Correct Option: A
Explanation:

The first mission dedicated to removing space debris from orbit was RemoveDEBRIS, which was launched in 2018.

Which international organization is responsible for coordinating efforts to mitigate space debris?

  1. United Nations Office for Outer Space Affairs (UNOOSA)

  2. International Space Station (ISS)

  3. European Space Agency (ESA)

  4. National Aeronautics and Space Administration (NASA)


Correct Option: A
Explanation:

The United Nations Office for Outer Space Affairs (UNOOSA) is responsible for coordinating efforts to mitigate space debris.

What is the term used to describe the accumulation of space debris in certain orbital regions?

  1. Space debris clusters

  2. Orbital debris clouds

  3. Space debris belts

  4. Orbital debris rings


Correct Option: A
Explanation:

The term 'space debris clusters' is used to describe the accumulation of space debris in certain orbital regions.

Which type of space debris poses the greatest risk to operational spacecraft?

  1. Large debris objects (greater than 10 centimeters)

  2. Small debris objects (less than 1 centimeter)

  3. Medium debris objects (1 to 10 centimeters)

  4. All debris objects pose an equal risk


Correct Option: A
Explanation:

Large debris objects (greater than 10 centimeters) pose the greatest risk to operational spacecraft due to their potential to cause catastrophic damage in the event of a collision.

What is the name of the proposed international treaty aimed at reducing space debris?

  1. Space Debris Mitigation Treaty

  2. Orbital Debris Reduction Treaty

  3. Space Pollution Prevention Treaty

  4. Space Environment Protection Treaty


Correct Option: A
Explanation:

The proposed international treaty aimed at reducing space debris is called the Space Debris Mitigation Treaty.

Which country has launched the most satellites into orbit?

  1. United States

  2. Russia

  3. China

  4. India


Correct Option: A
Explanation:

The United States has launched the most satellites into orbit, contributing to the increasing amount of space debris.

What is the term used to describe the process of removing space debris from orbit?

  1. Space debris removal

  2. Orbital debris mitigation

  3. Space environment cleanup

  4. Space pollution reduction


Correct Option: A
Explanation:

The term 'space debris removal' is used to describe the process of removing space debris from orbit.
