  4. A circular orbit used to maintain a constant altitude.


Correct Option: A
Explanation:

The Hohmann transfer orbit is an elliptical orbit used to transfer between two circular orbits with different radii.

What is the purpose of a geostationary orbit?

  1. To keep a satellite in a fixed position above the Earth.

  2. To allow a satellite to communicate with multiple ground stations.

  3. To provide a stable platform for scientific observations.

  4. To enable a satellite to escape from Earth's gravity.


Correct Option: A
Explanation:

A geostationary orbit is a circular orbit that keeps a satellite in a fixed position above the Earth.

What is the main challenge in designing a spacecraft trajectory?

Which of the following is NOT a type of spacecraft propulsion system?

  1. Chemical propulsion

  2. Electric propulsion

  3. Nuclear propulsion

  4. Solar sailing


Correct Option: D
Explanation:

Solar sailing is not a type of spacecraft propulsion system, as it relies on the pressure of sunlight to propel a spacecraft.

What is the purpose of a Lagrange point?

  1. To provide a stable location for spacecraft.

  2. To enable spacecraft to escape from Earth's gravity.

  3. To allow spacecraft to communicate with each other.

  4. To protect spacecraft from space debris.


Correct Option: A
Explanation:

Lagrange points are locations in space where the gravitational forces of two or more celestial bodies cancel each other out, providing a stable location for spacecraft.
