# Orbital Mechanics Questions and Answers – Chase Maneuvers

This set of Orbital Mechanics Multiple Choice Questions & Answers (MCQs) focuses on “Chase Maneuvers”.

1. How are chase maneuvers solved?
a) Euler’s problem
b) Kepler’s problem
c) Lambert’s problem
d) Jacobi problem

Explanation: Chase maneuvers are solved using Lambert’s problems. In chase maneuver, there are two spacecrafts which orbit in two non-coplanar elliptic orbits. One of the spacecraft tries to intercept the another one. This intercept trajectory is bi-elliptic orbital transfer.

2. Chase maneuvers are less energy demanding maneuvers.
a) True
b) False

Explanation: Chase maneuvers are considered to be energy demanding maneuvers which involves one spacrcraft trying to intercept the other spacecraft using bi-elliptic transfer orbit.

3. Chase maneuvers are considered to be impractical for which of these orbits?
a) LEO
b) GEO
c) MEO
d) HEO

Explanation: Chase maneuvers are considred to be impractical for Low Earth orbits as they are very energy demanding with high delta-v requirements. They are usually carried out for interplanetary missions.

4. Which of these is not an application of chase maneuver?
a) To target another spacecraft
b) Perform docking operation
c) For deorbiting
d) To catch up spacecraft for maintenance

Explanation: Chase maneuver is performed for docking operation. This is done in otder to carry out maintenance task, refuel another spacecrafts or deorbiting.

5. In a chase maneuver, what is the term used for passive spacecraft that is being chased?
a) Chaser
b) Target
c) Passive
d) Active

Explanation: When two spacecrafts are orbiting in a rendezvous, and one spacecraft tries to intercept the other spcecraft, the maneuvering spacecraft is known as ‘Chase’ and the one that is being chased is called ‘Target’.

6. In a chase maneuver, what is the term used for spacecraft that is chasing the other spacecraft?
a) Chase
b) Target
c) Passive
d) Active

Explanation: In case of chase maneuver, there are two spacecrafts involvolved in which one spacecraft chases the other. The term used for this spacecraft is ‘Chase’.
