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 ...
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]
Map all coordinates using OpenStreetMap. This list of impact structures on Earth contains a selection of the 190 confirmed craters given in the Earth Impact Database. [1] To keep the lists manageable, only the largest impact structures within a time period are included. Alphabetical lists for different continents can be found under Impact ...
The Geographic South Pole is marked by the stake on the right NASA image showing Antarctica and the South Pole in 2005. The South Pole, also known as the Geographic South Pole or Terrestrial South Pole, is the southernmost point on Earth and lies antipodally on the opposite side of Earth from the North Pole, at a distance of 20,004 km (12,430 miles) in all directions.
e. A continental shelf is a portion of a continent that is submerged under an area of relatively shallow water, known as a shelf sea. Much of these shelves were exposed by drops in sea level during glacial periods. The shelf surrounding an island is known as an insular shelf. The continental margin, between the continental shelf and the abyssal ...
An American architect, Robert Sarmast, claims that Atlantis lies at the bottom of the eastern Mediterranean within the Cyprus Basin. [7] In his book and on his web site, he argues that images prepared from sonar data of the sea bottom of the Cyprus Basin southeast of Cyprus show features resembling man-made structures on it at depths of 1,500 ...
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.
