A prolonged-retired NASA satellite burned up in Earth’s ambiance over the weekend, the agency has confirmed.
NASA launched the satellite, known as Orbiting Geophysics Observatory 1, or OGO-1, in September 1964, the principle in a sequence of 5 missions to lend a hand scientists brand the magnetic atmosphere round Earth. OGO-1 used to be the principle to commence nonetheless the final to drop out of orbit; the satellite had circled Earth aimlessly since its retirement in 1971.
But orbiting Earth is an advanced ingredient to construct, since the particles in our plush ambiance collide with spacecraft and slack them down, even at very excessive altitudes the build the ambiance is thin. That flee reduction moreover lowers the spacecraft’s altitude, till reentry becomes inevitable.

The 1,070-lb. (487 kilograms) OGO-1 skilled that inevitability on Saturday (Aug. 29), as NASA had predicted. The satellite re-entered at 4: 44 p.m. EDT (2044 GMT) over the southern Pacific Ocean and burned up in the ambiance, posing no chance to humans, NASA spokesperson Josh Handal suggested Condominium.com in an electronic mail.
The spacecraft hit the ambiance about 25 minutes earlier than NASA had forecast, Handal said, main to a reentry build east of the agency’s predictions. OGO-1 re-entered about 100 miles (160 kilometers) southeast of Tahiti, he added; moreover to tracking the satellite, NASA obtained reports of the match from folks on the island.
OGO launches persisted thru 1969, when OGO-5 started orbiting Earth, nonetheless all OGO-1’s successors had already re-entered Earth’s ambiance.
