Point Nemo, the water cemetery of the earth for spacecraft



& # 39; s Point Nemo & # 39; s; is a watery graveyard for titanium fuel tanks and other high-tech space junk

A place unlikely to land on Sunday the Tiangong-1

ground-based and out-of-control space lab is the lonely place in the South Pacific where it should crash.

Officially referred to as the "Ocean Spot of Inaccessibility," this water cemetery is better known for Titan fuel tanks and other high-tech space junk than Space Nemo, in honor of Jules Verne's fictional submarine captain.

Point Nemo is further from the country than any other point on the globe: 2,688 kilometers from the Pitcairn Islands in the north, one of the Easter Islands in the northwest and Maher Island – part of the Antarctic – in the south. 19659005] "Its most attractive feature for controlled reentry is that nobody lives there," said Stijn Lemmens, space junk expert for the European Space Agency in Darmstadt.

"Coincidentally, it's not biologically too so it's used as a dumping space cemetery" would be a more polite term – mainly for cargo spacecraft, "he told AFP.

About 250-300 spacecraft – mostly burned

By far the largest object descending from the sky to land at Point Nemo in 2001 was the Russian space laboratory MIR, which weighed 120 tons.

"It is routine for you are used today by the (Russian) Progress capsules that go back and forth to the International Space Station (ISS), "Lemmens said.

The mighty 420-ton ISS also has a meeting with fate at Point Nemo, in the Year 2024.

In the future, most spacecraft will be designed "for doom" with materials that melt at lower temperatures, making them less likely to survive reentry n and hit the earth's surface.

Both NASA and ESA, B. switch from titanium to alumium in the production of fuel tanks.

In 2011, China launched Tiangong-1, its first manned space laboratory, into space. It was earmarked for controlled re-entry, but ground engineers lost control in March 2016 of the eight-tonne craft in March 2016, when it began descening (19659005) The likelihood of someone hit by debris from Tiangong-1 is diminishing Data from the ESA vanishingly small, less than one in 12 trillion.

By the way, "Nemo" means "nobody" in Latin.
