What is the primary objective of orbital rendezvous?

  1. To bring two spacecraft together in the same orbit

  2. To transfer crew or cargo between spacecraft

  3. To repair or refuel a spacecraft in orbit

  4. To conduct scientific experiments in space


Correct Option: A
Explanation:

Orbital rendezvous is the process of bringing two spacecraft together in the same orbit, typically for the purpose of docking or transferring crew or cargo.

What is the most common type of orbital rendezvous maneuver?

  1. Hohmann transfer

  2. Rendezvous pitch maneuver

  3. Kozai maneuver

  4. Brouwer-Lyddane maneuver


Correct Option: A
Explanation:

The Hohmann transfer is the most common type of orbital rendezvous maneuver because it is relatively simple and efficient. It involves transferring a spacecraft from one circular orbit to another circular orbit with a different radius.

What is the purpose of the rendezvous pitch maneuver?

  1. To adjust the spacecraft's orbital plane

  2. To change the spacecraft's altitude

  3. To align the spacecraft's attitude with the target spacecraft

  4. To increase or decrease the spacecraft's velocity


Correct Option: C
Explanation:

The rendezvous pitch maneuver is used to align the spacecraft's attitude with the target spacecraft so that the two spacecraft can dock.

What is the Kozai maneuver used for?

  1. To change the spacecraft's orbital inclination

  2. To transfer a spacecraft between two non-coplanar orbits

  3. To increase or decrease the spacecraft's eccentricity

  4. To adjust the spacecraft's argument of periapsis


Correct Option: A
Explanation:

The Kozai maneuver is used to change the spacecraft's orbital inclination, which is the angle between the spacecraft's orbital plane and the reference plane.

What is the Brouwer-Lyddane maneuver used for?

  1. To adjust the spacecraft's orbital period

  2. To transfer a spacecraft between two elliptical orbits

  3. To increase or decrease the spacecraft's semi-major axis

  4. To change the spacecraft's eccentricity


Correct Option: A
Explanation:

The Brouwer-Lyddane maneuver is used to adjust the spacecraft's orbital period, which is the time it takes for the spacecraft to complete one orbit.

What is the most critical phase of orbital rendezvous?

  1. Initial contact

  2. Terminal rendezvous

  3. Docking

  4. Post-docking operations


Correct Option: C
Explanation:

Docking is the most critical phase of orbital rendezvous because it is the point at which the two spacecraft come into physical contact. If the docking procedure is not executed properly, it can result in damage to the spacecraft or even a catastrophic collision.

What is the purpose of a docking adapter?

  1. To provide a physical connection between the two spacecraft

  2. To transfer crew or cargo between the spacecraft

  3. To align the spacecraft's attitudes

  4. To provide electrical power to the spacecraft


Correct Option: A
Explanation:

A docking adapter is a device that provides a physical connection between the two spacecraft. It allows crew or cargo to be transferred between the spacecraft and also provides a structural connection between the two spacecraft.

What is the most common type of docking mechanism?

  1. Androgynous docking system

  2. Probe and drogue docking system

  3. Rigid docking system

  4. Magnetic docking system


Correct Option: A
Explanation:

The androgynous docking system is the most common type of docking mechanism because it is simple, reliable, and can be used with a variety of spacecraft.

What is the purpose of a docking ring?

  1. To provide a structural connection between the two spacecraft

  2. To align the spacecraft's attitudes

  3. To transfer crew or cargo between the spacecraft

  4. To provide electrical power to the spacecraft


Correct Option: A
Explanation:

A docking ring is a structural component that provides a connection between the two spacecraft. It is typically made of a lightweight material, such as aluminum or carbon fiber, and is designed to withstand the loads that are generated during docking.

What is the purpose of a docking latch?

  1. To secure the two spacecraft together

  2. To align the spacecraft's attitudes

  3. To transfer crew or cargo between the spacecraft

  4. To provide electrical power to the spacecraft


Correct Option: A
Explanation:

A docking latch is a mechanical device that secures the two spacecraft together. It is typically made of a high-strength material, such as steel or titanium, and is designed to withstand the loads that are generated during docking.

What is the purpose of a docking tunnel?

  1. To provide a passageway between the two spacecraft

  2. To align the spacecraft's attitudes

  3. To transfer crew or cargo between the spacecraft

  4. To provide electrical power to the spacecraft


Correct Option: A
Explanation:

A docking tunnel is a passageway that allows crew or cargo to be transferred between the two spacecraft. It is typically made of a lightweight material, such as aluminum or carbon fiber, and is designed to withstand the loads that are generated during docking.

What is the purpose of a docking port?

  1. To provide a connection point for the docking mechanism

  2. To align the spacecraft's attitudes

  3. To transfer crew or cargo between the spacecraft

  4. To provide electrical power to the spacecraft


Correct Option: A
Explanation:

A docking port is a connection point for the docking mechanism. It is typically located on the exterior of the spacecraft and is designed to accommodate the docking mechanism of the other spacecraft.

What is the purpose of a docking target?

  1. To provide a visual reference for the docking pilot

  2. To align the spacecraft's attitudes

  3. To transfer crew or cargo between the spacecraft

  4. To provide electrical power to the spacecraft


Correct Option: A
Explanation:

A docking target is a visual reference for the docking pilot. It is typically located on the exterior of the target spacecraft and is designed to help the docking pilot align the spacecraft with the docking port.

What is the purpose of a docking camera?

  1. To provide a visual reference for the docking pilot

  2. To align the spacecraft's attitudes

  3. To transfer crew or cargo between the spacecraft

  4. To provide electrical power to the spacecraft


Correct Option: A
Explanation:

A docking camera is a camera that provides a visual reference for the docking pilot. It is typically located on the exterior of the spacecraft and is designed to help the docking pilot align the spacecraft with the docking port.

What is the purpose of a docking sensor?

  1. To provide feedback to the docking pilot

  2. To align the spacecraft's attitudes

  3. To transfer crew or cargo between the spacecraft

  4. To provide electrical power to the spacecraft


Correct Option: A
Explanation:

A docking sensor is a sensor that provides feedback to the docking pilot. It is typically located on the exterior of the spacecraft and is designed to help the docking pilot align the spacecraft with the docking port.
