The world's oldest scientific satellite is still in orbit

From his desk at the European Space Operations Centre in Darmstadt, Germany, space debris analyst Tim Flohrer keeps track of the 23,000 or so catalogued objects currently orbiting the Earth. They range from spacecraft and satellites – some working, most not – to discarded rocket stages and fragmented space hardware. All of them the result of 60 years of space exploration.
Using radar data from the US Space Surveillance Network (also, primarily, the country’s early warning system) and observations from optical telescopes, Flohrer helps ensure none of this space junk puts operational spacecraft at risk.
Before we speak, I’ve asked him to check on object 1958-002B, also known as Vanguard 1. Launched in March 1958, this grapefruit-sized shiny metal sphere was boosted into a high elliptical orbit. And it’s still there, passing between 650 and 3,800km (406 to 2,375 miles) from the Earth.
“The earlier satellites, such as Sputnik, have all re-entered the atmosphere,” says Flohrer. “But I estimate that Vanguard 1 will remain in orbit for several hundred, if not a thousand years.”







In the 60's, people took acid to make the world weird. Now the world is weird and people take Prozac to make it normal.
