Question

When an orbiting spacecraft wishes to be recaptured by Earth’s gravity and begin the descent back to the surface, it performs a De-Orbit Burn with thrusters. The De-Orbit Burn must be done in which orbital direction?

Answer 1

Answer:(Retrograde Horizontal) - Pointing backwards along the orbital path)

Explanation: Deorbit Burn is a term used to describe the reverse movement of a space jet or Craft towards the Earth's atmosphere. Deorbit Burn is usually Preceeded by a process called (TIG) TIME OF IGNITION this process takes about one hour before the Spacecraft lands,it is the firing of the orbital maneuvering system. After launching the Deorbit Burn,it will possibly take between 30minutes to 45minutes before the Spacecraft will start to experience the impact of the Earth's Gravitational force.
