Point Nemo (Pole of Inaccessibility)
Full Name
Oceanic Pole of Inaccessibility (Point Nemo)
Technical Name
South Pacific Ocean Uninhabited Area (SPOUA)
Definition
The farthest point from land in the ocean
Distance
2688 kilometers away from the nearest landmass
Purpose
Spacecraft Cemetery
Usage
Due to its remoteness from human and ship trafficit is the safest re-entry zoneand hundreds of satellites have been deorbited here

Point Nemo (Pole of Inaccessibility) is a geographical region defined in technical literature as the "Oceanic Pole of Inaccessibility" or the "South Pacific Ocean Uninhabited Area" (SPOUA). This area, located at the center of the South Pacific Ocean, is the point on Earth farthest from any landmass. Due to its location and isolation, it is used by international space agencies as a controlled re-entry zone for decommissioned spacecraft, known as the spacecraft cemetery.

Geographical Location and Characteristics

Point Nemo is located in the South Pacific Ocean at coordinates 48°52.6′ South latitude and 123°23.6′ West longitude.【1】 This point is approximately 2,688 kilometers from the nearest landmasses (or over 1,600 miles according to some sources).【2】 The closest land formations to Point Nemo are Ducie Island, part of the Pitcairn Islands to the north, Motu Nui, part of Easter Island to the northeast, and Maher Island off the coast of Antarctica to the south.【3】

In geographical literature, the region is described as the "middle of nowhere" and is recognized as the location farthest from any human activity or settlement.【4】

Spacecraft Cemetery

Due to its isolation caused by ocean currents and wind patterns and the absence of human population, Point Nemo has been designated by the global space industry as a spacecraft cemetery.【5】 The primary purpose of this use is to minimize the risk of decommissioned spacecraft and satellites falling uncontrollably to Earth and potentially endangering populated areas or air and maritime traffic.【6】


History and Statistics: Since 1971, more than 263 spacecraft have been deliberately deorbited into the Point Nemo region.【7】 The majority of these controlled re-entry (splashdown) vehicles belong to Russia (and the former Soviet Union), the United States, Europe, and Japan.【8】

Important spacecraft and stations buried in this region include:


  • Mir Space Station: The station, operated by the Soviet Union and later Russia, was deorbited here at the end of its mission.【9】
  • Salyut Stations: Military space stations from the Soviet era.【10】
  • Skylab: The United States' first space station.【11】
  • Cargo Vehicles: Russian Progress cargo ships, the European Space Agency's ATV (Automated Transfer Vehicle), and Japan's HTV spacecraft.【12】
  • SpaceX Falcon 9: Rocket components from the private space transportation company SpaceX have also been deorbited into this region.【13】


Additionally, the International Space Station (ISS) is planned to be deorbited into this region upon completion of its mission in 2031.【14】


Process: When spacecraft are directed toward Point Nemo, they enter a process of atmospheric disintegration. During this process, fuel tanks and other combustible components burn up, while non-combustible metal parts and heavy fragments sink to the ocean floor.【15】

Environmental Characteristics and Biological Life

The South Pacific Gyre (SPG), where Point Nemo is located, is an oceanographically extremely low-nutrient (oligotrophic) region.【16】


Microbial Life: Scientific studies of seafloor sediments in the region have revealed the presence of microbial life despite extremely low energy and nutrient levels. Aerobic microorganisms have been found to remain viable in deep-sea sediments of the South Pacific Gyre, even within layers dating back approximately 101.5 million years from the surface to the volcanic basement.【17】 Although the metabolic activity of these microorganisms is extremely slow, observations in laboratory settings show they rapidly multiply when provided with nutrient supplements.【18】


Macroscopic Life: Due to ocean currents that prevent nutrient delivery, the region is described as a "biological desert." However, it is not entirely devoid of life; for example, in 2005, previously unknown species such as the Yeti crab (Kiwa hirsuta) were discovered near a point in this region, along the Pacific-Antarctic Ridge.【19】

Legal Status and Environmental Debates

Point Nemo and its surrounding area fall under the status of "Areas Beyond National Jurisdiction" (ABNJ), meaning they are not under the sovereignty of any state.【20】 This status requires that activities in the region be evaluated under international law, particularly the United Nations Convention on the Law of the Sea (UNCLOS) and the Outer Space Treaty.【21】


Environmental Impacts: While the deorbiting of spacecraft into the ocean (splashdown) is considered a necessary practice for space safety, its environmental effects remain a subject of debate. It has been noted that debris from re-entering spacecraft may contain toxic fuel residues (such as hydrazine), heavy metals, and other hazardous substances capable of harming marine ecosystems.【22】 Current international legal frameworks impose on states the obligation to protect the marine environment, but the absence of specific and binding norms addressing marine pollution caused by space activities creates a "legal gap."【23】

In legal doctrine, it is argued that these activities should be subject to environmental impact assessment (EIA) processes and that states bear a duty of "due diligence" under international law to protect marine life.【24】
