Stardust is a 3-axis stabilized spacecraft that maintains its attitude by firing a pair of its one sided- thrusters. this thruster arrangement causes Stardust to produce unbalanced torques at each thruster firing, which yields an undesired perturbing force and makes navigation a challenge. In addition to this perturbing force, Stardust Navigation contended with the problems caused by the contamination of the Navigation Camera and the experience of flying through 2 solar conjunctions during Stardust's inbound leg to the Wild 2 encounter. Both the contamination and the solar conjunctions were major challenges Navigation had to overcome.
