Spacecraft cemetery. The spacecraft cemetery, known more formally as the South Pacific Ocean (ic) Uninhabited Area, [1][2] is a region in the southern Pacific Ocean east of New Zealand, [3] where spacecraft that have reached the end of their usefulness are routinely crashed. The area is roughly centered on "Point Nemo", the oceanic pole of ...
An artificial reef (AR) is a human-created freshwater or marine benthic structure. [1] Typically built in areas with a generally featureless bottom to promote marine life, it may be intended to control erosion, protect coastal areas, block ship passage, block the use of trawling nets, [2] support reef restoration, improve aquaculture, or enhance scuba diving and surfing.

It communicates through the NASA Deep Space Network (DSN) to receive routine commands and to transmit data to Earth. Real-time distance and velocity data are provided by NASA and JPL. [4] At a distance of 164.0 AU (24.5 billion km; 15.2 billion mi) from Earth as of September 2024, [4] it is the most distant human-made object from Earth. [5]
The claim that the Great Wall of China is the only man-made object visible from the Moon or outer space has been debunked many times, but remains a common misconception in popular culture. [1] [2] [3] According to astronauts Eugene Cernan and Ed Lu, the Great Wall is visible from the lower part of low Earth orbit, but only under very favorable ...
The Southern Ocean, also known as the Antarctic Ocean, [ 1 ][ note 4 ] comprises the southernmost waters of the world ocean, generally taken to be south of 60° S latitude and encircling Antarctica. [ 5 ] With a size of 20,327,000 km 2 (7,848,000 sq mi), it is the second-smallest of the five principal oceanic divisions, smaller than the Pacific ...
Space debris (also known as space junk, space pollution, [ 1 ]space waste, space trash, space garbage, or cosmic debris[ 2 ]) are defunct human-made objects in space – principally in Earth orbit – which no longer serve a useful function. These include derelict spacecraft (nonfunctional spacecraft and abandoned launch vehicle stages ...
ʻOumuamua is a small object estimated to be between 100 and 1,000 metres (300 and 3,000 ft) long, with its width and thickness both estimated between 35 and 167 metres (115 and 548 ft). [ 13 ] It has a red color, like objects in the outer Solar System.
