Russia and its partners plan to plunge the International Space Station (ISS) into the ocean at the end of its life cycle after 2020 so as not to leave space junk, its space agency said on Wednesday.
"After it completes its existence, we will be forced to sink the ISS. It cannot be left in orbit, it's too complex, too heavy an object, it can leave behind lots of rubbish," said deputy head of Roskosmos space agency Vitaly Davydov.
"Right now we've agreed with our partners that the station will be used until approximately 2020," he said in comments released on Wednesday.
Space junk is becoming an increasingly serious headache.
A piece of space debris narrowly missed the space station last month in a rare incident that forced the six-member crew to scramble to their rescue craft.
The ISS, which orbits 350 kilometres (220 miles) above Earth, is a sophisticated platform for scientific experiments bringing together space agencies from Russia, the United States, Europe, Japan, and Canada.
Launched in 1998, the ISS was initially expected to remain in space for 15 years until an agreement was reached to keep it operating through 2020.
By going into a watery grave, the ISS will repeat the fate of its predecessor space station Mir, which Russia sank in the Pacific Ocean in 2001 after 15 years of service.
Moscow this month proclaimed the beginning of "the era of the Soyuz" after the US shuttle's last flight left the Russian system as the sole means for delivering astronauts to the ISS.
Russia is currently developing a new space ship to replace the Soyuz capsule which is single-use, except for the section in which spacemen return to Earth, said Davydov.
Tests of the ship will begin after 2015 and it will have "elements of multi-use whose level will be much higher than they are today," he said, adding that Russia will compete with the United States in building the new-generation ship.
"We'll race each other."
Davydov said it remains unclear what will come after the ISS and whether mankind will see the need for a replacement orbiting close to Earth.
"Lots of our tasks are still linked to circumterrestrial space," he said, while adding that a new space station could be used as a base for building complexes that will explore deeper into space.
"I cannot rule out that it will be used to put together, create the complexes that in the future will fly to the Moon and Mars," he said, stressing that "a serious exploration" could not be done without manned flights.

Seeing 2020: Russian Outcry Delays Sinking of International Space Station (International Business Times)
The Russian space agency's deputy head Vitaly Davydov’s comments forced Russia’s space agency to back off after an international outcry on Thursday.
Davydov on Wednesday said that Russia planned to sink the International Space Station into the Pacific Ocean in 2020.
"The partners have agreed to continue the ISS operation until 2020. The partners will also approve an extended period of the ISS," the agency's Press Secretary Anna Vedishcheva told Russian news agency Interfax-AVN on Thursday.
In an effort to keep outer space clean and junk-free, Russia and its partners had planned to sink the International Space Station (ISS) in the ocean after its scheduled retirement in 2020, Russian Space Agency Roscosmos said in a statement on Wednesday.
During a meet of the international science agencies in 2010, most of them agreed on an extended period of operation, but Vedischeva stressed the space base’s fate: a watery grave at the depths of the Pacific Ocean.
"The only way to dispose of the station is to sink it," Vedishcheva said.
The International Space Station was placed in Earth’s lower orbit in 1998 and is a joint project of space agencies from the United States, Russia, Europe, Canada and Japan.
Space junk can be disastrous for spacecrafts and satellites, according to astronauts. The Mir space station was also sunk by Russia into the Pacific Ocean in 2001 when its 15-year life cycle ended.
Russia strives to lead in space exploration after NASA’s 30-year space shuttle mission ended on July 21 with successful landing of the final space shuttle, Atlantis.

Russia Reveals Plan to Sink International Space Station (Interfax)
Russian officials are calling for calm saying that the sinking of the International Space Station (ISS) in the Pacific Ocean is not a big deal, and that it would not happen anytime soon.
After startling some members of the public with statements made earlier this week about retiring the ISS in 2020 and letting it sink into ocean waters, officials with Russian Space Agency Roscosmos insist that there is no need to worry.
Seeking to clarify statements made by Vitaly Davydov, deputy head of Roscosmos, officials insist that the agency has no such plans for the International Space Station (ISS).
Russian, American, Japanese, European, and Canadian representatives of the ISS say they actually plan to use the space station well into 2028, assuming the station is still functional.
Furor had erupted after Davydov said in an interview on Russian television Wednesday that the agency had no choice but to let the ISS fall into the ocean.
"After it completes its existence, we will be forced to sink the ISS. It cannot be left in orbit, it's too complex, too heavy an object, it can leave behind lots of rubbish," Davydov said, according to a transcript published on the space agency’s website.
Officials insist Davydov's statements were taken out of context. However, his statements were echoed Thursday by the Russian space agency’s press secretary, Anna Vedishscheva, who noted the station’s retirement would be in 2020.
"The partners have agreed to continue the ISS operation until 2020. The partners will also approve an extended period of the ISS use and the procedure of its disposal. The only way to dispose of the station is to sink it," Vedishcheva told the Interfax News Agency.
Space agency partners have not revealed what might happen to the International Space Station once 2028 comes and goes. However, sinking the structure into ocean waters would not be unusual; the former space station, Mir, was also disposed of in the Pacific Ocean in 2001 after 15 years of service.
The ISS is funded for the next nine years, according to CBS News space analyst William Harwood, and would need more funding if space agency partners plan to use the station beyond 2020.
"With something as large as the station, they'll do a targeted re-entry to make sure it doesn't rain down on, say, New York,” Harwood told the network.
With NASA’s space fleet now officially retired, Russia is currently the only agency partner capable of transporting astronauts to and from the ISS.
The ISS orbits 220 miles above Earth and is used by NASA and other space agency partners to conduct experiments.
