What is the primary purpose of an orbital maneuver?

  1. To change the spacecraft's velocity

  2. To change the spacecraft's altitude

  3. To change the spacecraft's inclination

  4. To change the spacecraft's argument of perigee

Show answer
Correct Option: A
Explanation:

Orbital maneuvers are primarily used to change the spacecraft's velocity, which in turn changes its trajectory.

Which of the following is NOT a type of orbital maneuver?

  1. Hohmann transfer

  2. Bi-elliptic transfer

  3. Plane change maneuver

  4. Rendezvous maneuver

Show answer
Correct Option: D
Explanation:

Rendezvous maneuvers are not orbital maneuvers in the traditional sense, as they do not involve changing the spacecraft's trajectory. Instead, they are used to bring two spacecraft together in the same orbit.

What is the most efficient way to transfer from one circular orbit to another circular orbit with a different radius?

  1. Hohmann transfer

  2. Bi-elliptic transfer

  3. Plane change maneuver

  4. Rendezvous maneuver

Show answer
Correct Option: A
Explanation:

The Hohmann transfer is the most efficient way to transfer from one circular orbit to another circular orbit with a different radius. It involves two burns: one to raise the spacecraft's perigee to the desired apogee, and another to lower the spacecraft's apogee to the desired perigee.

What is the purpose of a plane change maneuver?

  1. To change the spacecraft's velocity

  2. To change the spacecraft's altitude

  3. To change the spacecraft's inclination

  4. To change the spacecraft's argument of perigee

Show answer
Correct Option: C
Explanation:

Plane change maneuvers are used to change the spacecraft's inclination, which is the angle between the spacecraft's orbital plane and the reference plane (usually the ecliptic plane).

What is the purpose of an argument of perigee maneuver?

  1. To change the spacecraft's velocity

  2. To change the spacecraft's altitude

  3. To change the spacecraft's inclination

  4. To change the spacecraft's argument of perigee

Show answer
Correct Option: D
Explanation:

Argument of perigee maneuvers are used to change the spacecraft's argument of perigee, which is the angle between the ascending node and the perigee.

What is the most efficient way to transfer from one elliptical orbit to another elliptical orbit with a different apogee and perigee?

  1. Hohmann transfer

  2. Bi-elliptic transfer

  3. Plane change maneuver

  4. Rendezvous maneuver

Show answer
Correct Option: B
Explanation:

The bi-elliptic transfer is the most efficient way to transfer from one elliptical orbit to another elliptical orbit with a different apogee and perigee. It involves two burns: one to raise the spacecraft's perigee to a higher apogee, and another to lower the spacecraft's apogee to the desired perigee.

What is the purpose of a Hohmann transfer?

  1. To transfer from one circular orbit to another circular orbit with a different radius

  2. To transfer from one elliptical orbit to another elliptical orbit with a different apogee and perigee

  3. To change the spacecraft's inclination

  4. To change the spacecraft's argument of perigee

Show answer
Correct Option: A
Explanation:

Hohmann transfers are used to transfer from one circular orbit to another circular orbit with a different radius.

What is the purpose of a rendezvous maneuver?

  1. To change the spacecraft's velocity

  2. To change the spacecraft's altitude

  3. To change the spacecraft's inclination

  4. To bring two spacecraft together in the same orbit

Show answer
Correct Option: D
Explanation:

Rendezvous maneuvers are used to bring two spacecraft together in the same orbit.

Explanation:

Plane change maneuvers are the most efficient way to transfer from one elliptical orbit to another elliptical orbit with a different inclination.

What is the purpose of an argument of perigee maneuver?

  1. To change the spacecraft's velocity

  2. To change the spacecraft's altitude

  3. To change the spacecraft's inclination

  4. To change the spacecraft's argument of perigee

Show answer
Correct Option: D
Explanation:

Argument of perigee maneuvers are used to change the spacecraft's argument of perigee, which is the angle between the ascending node and the perigee.

What is the most efficient way to transfer from one circular orbit to another circular orbit with a different argument of perigee?

  1. Hohmann transfer

  2. Bi-elliptic transfer

  3. Plane change maneuver

  4. Argument of perigee maneuver

Show answer
Correct Option: D
Explanation:

Argument of perigee maneuvers are the most efficient way to transfer from one circular orbit to another circular orbit with a different argument of perigee.
