Our solar system is dynamic and ever-changing, and there are many unanswered questions concerning both its origin and its future. During the Shuttle-Mir program, scientists studied the history of the development of the different planetary systems, as well as the outlook for our own planet Earth.
The Space Sciences experiments were designed to capture cosmic dust over a 6 month to 1 year period of time. During the Mir-21/NASA-2 mission, EVAs were performed to externally mount these experiments to the Kvant-2 module of the Mir Space Station, where they were left to capture the cosmic dust particles. A second EVA was performed to retrieve the experiments and return them to Earth, where scientists performed chemical, organic and mineralogical analyses on the cosmic particles.
