The Orbiting Geophysics Observatory 1 spacecraft or OGO-1, launched in September 1964 to study Earth’s magnetic environment and how our planet interacts with the sun, which was officially decommissioned in 1971 and has been zooming silently around Earth, will re-enter and will burn in the Earth atmosphere this weekend falling to Earth. OGO-1 was the first satellite in the six-spacecraft OGO program, whose other members launched in 1965, 1966, 1967, 1968 and 1969. Those five have all come back to Earth, most recently in 2011, re-entering over various patches of ocean. Regarding the end of existence of OGO 1, NASA said in a press release: “The spacecraft will break up in the atmosphere and poses no threat to our planet, or anyone on it , and this is a normal final operational occurrence for retired spacecraft.”

The satellite is likely to enter over the South Pacific region. OGO 1’s orbit has changed quite a bit since its launch on September 5, 1964. Weighing in at 1,074 pounds (487 kilograms), OGO 1 is one of the largest artificial objects to reenter since the Chinese space station Tiangong 2 in July 2019.
