The 10 Oldest Satellites Still in Orbit
Sputnik burned up after three months. Explorer 1 held on until 1970. But ten satellites from the Eisenhower and Kennedy years are still up there - including one that will outlast everyone reading this.

The Biggest Dead Thing in Orbit Has a 150-Year Lease
In January 2010, controllers fired Envisat's thrusters twice to dodge a Chinese rocket stage that would have missed by 48 meters. Two years later the eight-tonne flagship went silent mid-orbit, and nobody has been able to move it since. It now shares its altitude with 6,171 tracked objects, and it will keep crossing their paths until roughly the 2160s.

10 GPS Facts Most People Get Wrong
Your phone has never sent a single bit to a GPS satellite. There are 31 of them, not thousands. And without two corrections borrowed from Einstein, every map app on Earth would drift ten kilometers a day.

China Destroyed One Satellite in 2007. It Is Still Nearly a Fifth of All Tracked Debris.
On January 22, 2013, a small glass sphere in polar orbit abruptly started spinning nearly three times as fast. The thing that hit it had been waiting there for six years. Nineteen years after China shot down its own weather satellite, our catalog still carries 2,318 fragments of Fengyun-1C in orbit, nearly one in five cataloged debris objects circling Earth.

10 Things You Didn't Know Are Being Tracked in Orbit
A scrap of plastic film that came off a balloon in 1960 still gets its orbit measured, sixty-six years later. So do 2,319 pieces of one shattered weather satellite and a spy satellite that spent 38 years filed under a fake name. Meet the strangest custody arrangements in the sky.

Intelsat 33e Died at 4:30 in the Morning and Took the Neighborhood With It
A $400 million communications satellite went silent over the Indian Ocean in October 2024 and turned into hundreds of pieces of permanent debris in the one orbit that never cleans itself. Uninsured. Cause unknown. Our archive has been watching the fragments spread through the GEO belt ever since.
