What are the highly hierarchical deep space mission, those where one thing deploys the next which deploys the next... An example would be Tianwen-1 where a Mars orbiter deployed a Mars lander which then deployed a Mars rover which then deployed a stand-alone selfie cam. Ultimate goal is to find out if Tianwen-1 wins as the highest order hierarchical deployment and/or if it was the first third-order hierarchical deployment in deep space. Answers can be any mission with two or more hierarchical deployments that take place in deep space.
