Multiple uses- taking satellites into orbit, repairing damaged satellites, carrying astronauts and equipment. Objective: Explain how artificial satellites and space probes are used to explore space. . Key Terms:. Satellite. orbit. Artificial satellites. A satellite is any object, natural or artificial, that follows a curved path around another object in space. The curved path of the object is its orbit.. Based on Functions. Passive Satellite – a communications satellite not equipped with electronic devices to retransmit communications. Such satellite acts only as a reflector of radio waves..
