The satellite was built by a team at Bell Telephone Laboratories that included John Robinson Pierce, who created the project; [4] Rudy Kompfner, who invented the traveling-wave tube transponder that the satellite used; [4] [5] and James M. Early, who designed its transistors and solar panels. [6]
On 19 April 1975, the satellite's 96.46-minute orbit had an apogee of 619 kilometres (385 mi) and a perigee of 563 kilometres (350 mi), at an inclination of 50.7 degrees. [6] [3] It was built to conduct experiments in X-ray astronomy, aeronomics, and solar physics. The spacecraft was a 26-sided polyhedron 1.4 metres (4.6 ft) in diameter.
