[2] [4] [5] [6] Later, Shiyan 7 shifted to rendezvous with Shijian 7 (of unknown mission) with whom it maintained proximity from 19 to 20 August 2013 until it maneuvered into a 5 km lower orbit. [ 4 ] [ 7 ] Drawing further suspicion, around 19 October 2013, Shiyan 7 maneuvered to a 1 km higher orbit and released a previously untracked object ...
The South Pacific garbage patch is an area of ocean with increased levels of marine debris and plastic particle pollution, within the ocean's pelagic zone. This area is in the South Pacific Gyre , which itself spans from waters east of Australia to the South American continent, as far north as the Equator , and south until reaching the ...
First flight of Long March 5B. Some debris from the CZ-5B's core stage may have survived reentry and fell on villages in the Ivory Coast.

The Inter-Agency Space Debris Coordination Committee (IADC) is an inter-governmental forum whose aim is to co-ordinate efforts to deal with debris in orbit around the Earth founded in 1993. The primary purposes of the IADC is information exchange on space debris research activities, facilitating opportunities for joint research, and reviewing ...
The degradation of plastics in the ocean also leads to a rise in the level of toxics in the area. [21] The garbage patch was confirmed in mid-2017, and has been compared to the Great Pacific Garbage Patch's state in 2007, making the former ten years younger. The South Pacific garbage patch is not visible on satellites, and is not a landmass.
A garbage patch is a gyre of marine debris particles caused by the effects of ocean currents and increasing plastic pollution by human populations. These human-caused collections of plastic and other debris are responsible for ecosystem and environmental problems that affect marine life, contaminate oceans with toxic chemicals, and contribute ...
