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 LDEF satellite deployed by mission STS-41-C Challenger and retrieved by STS-32 Columbia spent 68 months in orbit to gather debris data. The EURECA satellite, deployed by STS-46 Atlantis in 1992 and retrieved by STS-57 Endeavour in 1993, was also used for debris study. [156]
Satellites at altitudes towards the lower bound of MEO can use the "25-year rule" to decelerate with onboard propulsion so that it will fall out of orbit within 25 years, but this provision is only allowed if satellite operators can prove by statistical analysis that there is less than a 1/10,000 chance that the atmospheric reentry will cause ...
From 1960 to 1970, the site consisted of seven waste disposal lagoons and open storage of 10,000 to 15,000 drums. Testing of groundwater found it to contain volatile organic compounds (VOCs). Soil sampling identified VOCs, phthalates, polychlorinated biphenyls (PCBs), and metals including lead and chromium.
