A Spacecraft Graveyard in the Most Remote Place on Earth

Few people have ever seen the loneliest place on our planet, Point Nemo. Nope, it’s not in Antarctica. This spot lies more than 13,000 ft deep in the South Pacific Ocean. But that's not the only amazing thing Point Nemo is famous for. Once, someone decided that it would make a perfect place to crash defunct satellites - and that's how Point Nemo has become the world's only spacecraft graveyard.
The Oceanic Point of Inaccessibility, which is another name for Point Nemo, is the most remote place on Earth. In fact, it's so isolated, that at any given moment, the people closest to this location are probably astronauts! The thing is, this spot has a much closer connection to space than you might think!

SUMMARY:
- There are two ways to get rid of dead satellites. If a satellite's orbit lies very high above our planet, it's easier to blast it into outer space than return it to Earth.
- But if a satellite isn't large and is moving relatively low, engineers use what fuel is left in its tanks to slow it down. As a result, the thing just falls out of its orbit and starts to approach Earth at the breakneck speed of over 17,000 miles per hour.
- What about the big stuff, like large satellites or even space stations? The problem with them is that they might not burn up entirely before they reach the surface of our Earth, which is a terrible safety risk.
- That's when the Point of Inaccessibility comes into play. Aerospace engineers appreciate that they "can put things down" in Point Nemo without hitting anything.
- Since 1971, when Point Nemo was chosen for a spacecraft graveyard, space agencies have already dumped more than 260 dead satellites into the ocean. The largest spacecraft is Russia's MIR space lab, buried under 2 miles of water.
- Dead spacecraft aren't tucked carefully together on the bottom. Since even large spacecraft burn up as they enter the atmosphere, it's not a whole object that touches the surface of the water.
- If all the space around our planet gets crowded with satellites, both functioning and dead, people will face the serious problem of space junk.
- The most dangerous thing might be one large piece of space debris hitting another. Not that it happens often, but it does happen.
- Most modern spacecraft have built-in systems that help to de-orbit them and land in the designated area.
- The most hilarious thing about the Point of Inaccessibility is that the man who discovered it has never been there! It was 1992 when Hrvoje Lukatela, a Croatian survey engineer, used a computer program that figured out which spot was the farthest distance from all other land coordinates.
