UHURU detects X-ray sources
These unexpected discoveries were the starting point of experimental X-ray astronomy. Increasing numbers of researchers worked in this field, and thus more and more X-ray sources were discovered in outer space. With the rocket experiments at that time, however, it was very difficult to investigate these objects in detail as the observation times were simply too short. Thus Giacconi began to construct a satellite that would be able to continuously search the sky for X-ray sources. He completed his project in 1970: the satellite called UHURU (which means freedom in Swahili) was launched into space from a rocket station in Kenya. Within just one week, he discovered more X-ray sources than had been found in all prior experiments.
