What are the objects floating in space? Bodies, sports cars, urine crystals, everything!

1, the famous writer Douglas Adams once said that space is extremely huge.
because it is so vast that many people think it is completely empty, and space is named.
is the case, with only 4% of space filled with matter, most of which are planets, galaxies, black holes and all sorts of weird cosmic hoaxes, but there are some very strange things out there.
fact, thanks to human intervention, there are many strange objects floating among the stars.
2, Musk's sports car is one of the newest residents in space.
February 6, 2018, SpaceX, a U.S. space exploration technology company, test-fired a Falcon Heavy rocket carrying a very special cargo, Elon Musk's Tesla Roadster.
expects the car to start orbiting the sun and then move closer to Mars.
considering that the car is full of bacteria, this could have an unpredictable effect on the red planet.
3, the discovery of Pluto's human space funeral is not particularly new, the idea of sending your ashes into the universe has been around for decades, starting with Gene Roddenberry, creator of Star Trek, who became the first dead person to fly into outer space aboard the space shuttle Columbia.
besides, the ashes of Clyde Tombaugh, an American astronomer who discovered Pluto in 1930, were even sent to places never had been.
long after his death, his ashes were brought into space by the New Horizons spacecraft, eventually hoping they would successfully leave the solar system.
4, urine crystals in all the movies, books and documentaries, space flight seems to be a very romantic thing, with the twinkling aurora, dawnons on the Earth's horizon, and a battle on the space station.
but there is a dark side to everything.
astronauts, who are frugal, insist on recycling everything, even the waste that the spacecraft has abandoned.
sometimes, urine and excess water are sprayed into the splendid universe, where it freezes into tiny droplets of ice. After
, the ice melts into water vapor and floats in space.
5, America's stupid plan of the Cold War was a strange time, a time of crazy planning, singular military innovation, and unexplained competition between East and West.
, however, perhaps most inconceivable, the United States is trying to reinvent the ionosphere of the entire planet, only to protect weaknesses in its communications systems.
underwater cables (for telecommunications) vulnerable to Soviet attacks, and if such an attack is successful, the United States will be forced to communicate with the world over radio.
the problem is that the ionosphere that allows such broadcasts is often disturbed by solar activity.
solution is Project West Ford.
millions of tiny pieces of copper were sent into space, forming permanent radio reflectors that would prevent soviet or solar attacks.
in short, it didn't work, and most of the unnecessary stuff ended up burning up when it re-entered the atmosphere.
however, there are still thousands of pieces of copper gathered there to form a cosmic monument.
6, a large number of animal carcasses, although humans often boast of their achievements in space exploration, but we rarely appreciate the field of unsung heroes.
We often use animals to test the dangers of space before sending astronauts into space.
1947, a flock of fruit flies was lucky when they were successfully sent into space and safely returned to Earth.
followed by Albert I, the rhesus monkey, who died of asphyxiation during the flight.
Albert II died on his way back to Earth.
dog named Laika, perhaps the most famous cosmic creature, died shortly after launch.
for decades to come, other countries continue to send monkeys into space.
some burned to death when they returned to Earth, others were permanently trapped in floating graves in space. What could be more impressive than the space debris sent to the depths of the solar system
7, the giant back-to-fly rod? That's the space debris that can come back.
the Apollo 12 rocket separated from a spacecraft that sent Charles Conrad and Alan L. Bean to the moon, part of the rocket engine went into deep space and began orbiting the sun.
However, in the early 2000s, it flew back, and bewildered scientists initially thought it was an asteroid, J002E3.
eventually, it began orbiting the Earth, approaching the Earth, and even seriously threatening other satellites.
most likely, J002E3 will eventually burn up in the Earth's atmosphere or hit the moon.
8, the mysterious object Niku in the vast expanse of space, sometimes scientists will find a lot of things that simply can not be explained.
, however, they usually exist hundreds or thousands of light-years away from Earth, not on our doorstep.
, for example, Niku, a mysterious object found on the edge of our solar system, and experts are puzzled.
Niku's biggest feature is its retrograde orbit, which means it is in the opposite direction to other objects in the solar system.
it exists somewhere outside Neptune's orbit, accompanied by five other objects with similar characteristics, all of which run on the same plane.
even more curious, studies have shown that they may have been in these orbits for millions of years, and that more objects in the sky may be running in a similar way.
why they do it, and why they're piling up, remains a mystery.
9, a satellite that could destroy everything, in the film Gravity, depicts a phenomenon called Kessler syndrome, in which a piece of space debris collides with another piece of debris and then attracts more debris to collide, slowly forming a cluster of killer garbage that can devour anything that is blocked in its orbit.
May this could happen, experts have been concerned about Kessler syndrome and its potentially devastating impact on the Earth's global network.
engineers Charlotte Bewick and Donald Kessler think this has happened. One of the biggest potential incentives for
is Envisat, an ESA satellite that was decommissioned in 2013.
the giant satellite is no longer able to drive, it has become a "time bomb" and is waiting to collide with another piece of debris and trigger a chain reaction.
10, The Golden Globe Voyager is perhaps one of the most famous space missions of all time and one of the most profound and impressive space feats ever accomplished by mankind.
Voyager 1 and Voyager 2 were launched into the solar system to study the planets, and after overtaking them, they are now in deep space, Voyager 1 is now in interstellar space, Voyager 2 in the sun, far beyond the edge of Pluto's orbit. The most famous item in the
Traveler program is The Golden Record, which compiles a great deal of Earth music and contains many other information that can be discovered by other space shuttles in the distant future as part of a time capsule.
among the songs selected include Bach's Brandenburg Concerto No. 2, Zaire and Chuck Berry's Johnny B. Goode.
11, huge reservoirs in space, you may never think of how much water there there.
2011, two groups of astronomers discovered the largest "water reservoir" ever discovered in the universe, about 140 trillion times the amount of water stored in all of Earth's oceans, orbiting giant black holes 12 billion light-years from Earth.
black hole itself is called a quasar, it is 20 billion times the size of the sun and produces 1,000 trillion times the energy of the sun.
Although astronomers believe that water exists in distant space, they have never really looked at it before, let alone so much water.
