The information they supply enables scientists to build up a picture of the objects in space. These instruments rely on the main structure of the space probe to transport, protect, and power them. Scientists often have to design instruments to work in unknown conditions and investigate objects previously viewed only: from Earth. Because of the distances that the space probes have to travel, scientists may have to wait years before the instruments start to ...
