 A solid propellent de-orbit mortar nudged the craft into lunar orbit, while spin thrusters stabilized the orientation enabling imaging system to capture the descent profile.The probe's external surface had four oval-shaped anodised aluminium plates measuring 120mm X 180 mm on which the image of the Indian flag was depicted, complete with the Emblem of India and the words "Satyameva Jayate".These plates were attached to each one of the four vertical sides of the probe.
