The Envisat satellite is a large, inactive satellite with a mass of 8,211 kg (18,102 lb) that orbits at 785 km (488 mi), an altitude where the debris environment is the greatest—two catalogued objects can be expected to pass within about 200 m (660 ft) of Envisat every year [40] —and likely to increase. Don Kessler predicted in 2012 that it ...
The 22 January 2013 collision between debris from Fengyun FY-1C satellite and the Russian BLITS nano-satellite. The 22 May 2013 collision between two CubeSats, Ecuador's NEE-01 Pegaso and Argentina's CubeBug-1, and the particles of a debris cloud around a Tsyklon-3 upper stage (SCN 15890) [2] left over from the launch of Kosmos 1666.
The table below is arranged by the continent's percentage of the Earth's land area, and where Asian and Russian structures are grouped together per EID convention. The global distribution of known impact structures apparently shows a surprising asymmetry, [ 37 ] with the small but well-funded European continent having a large percentage of ...
This satellite had been deactivated prior to the collision, and remained in orbit as space debris. The other spacecraft, Iridium 33, was a 560-kilogram (1,200 lb) U.S.-built commercial satellite that was part of the Iridium constellation for satellite phones. [2] It was launched on September 14, 1997, atop a Russian Proton rocket.
Space junk has filled up so much of Earth's orbit that it's endangering satellites and astronauts. The company Kayhan Space issues roughly 1,000 space-collision warnings per day.
There were 190 known satellite breakups between 1961 and 2006. [2] By 2015, the total had grown to 250 on-orbit fragmentation events. [3] As of 2012 there were an estimated 500,000 pieces of debris in orbit, [4] with 300,000 pieces below 2000 km . [1] Of the total, about 20,000 are tracked. [1]
The Earth-observing ERS-2 satellite first launched on April 21, 1995, and it was the most sophisticated satellite of its kind at the time to be developed and launched by Europe.
