Echo 1A (commonly referred to as just Echo 1) was put successfully into a *944-to-1,048-mile*(1,519 to 1,687 km) orbit by another Thor-Delta,[4][5] and a microwave transmission from the Jet Propulsion Laboratory in Pasadena, California, was received at Bell Laboratories in Holmdel, New Jersey, on August 12,[2] 1960.
