Ariel (UK satellites)
Ariel 1 (UK-1 before orbit) was built by NASA's Goddard Space Flight Center and instrumented with six British experiments to make integrated measurements in the ionosphere. Ariel 2, contained three UK-built experiments and was placed in orbit two years later. Ariel 3, designed and built in the United Kingdom, carried five experiments. The UK-built Ariel 4 carried four UK and one US experiment to investigate plasma, charged particles, and electromagnetic waves in the ionosphere.
Ariel 5 was one of the earliest X-ray astronomy satellites and involved a British-American collaboration. The Science Research Council managed the project for the United Kingdom and the Goddard Space Flight Center for the United States. Several catalogs of X-rays sources stemmed from its observations which continued until the spring of 1980.
