This is something space power has not achieved.
And this is confirmed by the "new world order" in lunatic research.
Chinese probe Changand 4 This Thursday became the first ship to land on the hidden moon side.
The mission is a "historical step in space exploration," according to Chinese press, and will enable exploration of the lesser-known side of our satellite, experiments with living organisms such as potato seeds and silkworm shells.
In the BBC Mundo we are telling you about the four ambitious scientific goals of the historic Chinese mission.
1. Study the mega shock in the history of the Solar System
The hidden face of the moon is also called the "dark side" of our satellite, not because it lacks light, but because it is largely unknown.
This side that we never see from Earth is radically different from the visible person and it is covered with craters.
Chang 4 landed on a flat surface of about 200 km of crater called Von Kárman, which in turn is in the large pool, Depression Aitkena.
– This gigantic depression has 2,500 km in diameter and 13 km in depthAndrew Coates, a physics professor at the University of London, explained to the BBC.
"It is the product of one of the greatest influences in the solar system.
"It is believed that the shock that created the great depression was so powerful that it had pierced the moon to the mantle," Coates added.
Chinese explorers will try to direct their instruments to the rocks of the cloak exposed in that pool.
Craters in Depression Aitken are records of the effects of the Moon, and perhaps the Earth, through its history.
How influential are these influences for life? Chang # 4 can help find answers.
2. Explore the bark and the interior of the moon
Many instruments in the probe are replicas of its predecessor, Change 3, which landed in 2013 on the visible side of the moon.
Among these instruments are cameras that have already started recording and sending revealing images of the hidden side of our satellite.
This is one of the biggest challenges for the mission on the hidden moon side The moon's body just blocks data transfer directly.
That is why the Chinese mission uses satellite, Quiquiao, which is 60,000 km from the Moon and communicates with the Earth.
Chang # 4 also has a radar that can penetrate the Moon's surface, The bore is thicker on the dark side of the Moon than on the visible side where the bark of the thorn is subject to the eruptions of the magma produced by the sea, the dark areas that can be seen with the naked eye.
The mission to follow the one who landed this Thursday, and who will have a name changeand 5will look for lunar surface patterns and return them to Earth.
3. A unique opportunity for radio astronomy
The mission has a spectrometer that will allow for the study of solar radiation. And with the Quequiao satellite instrument, it can work as a radio telescope.
The hidden side of the Moon is ideal for radio astronomy research because The moon's body blocks the noise of the ionsorearth spheres and human radio transmissions.
Chang # 4 will allow you to notice low frequency radio waves which can not be captured from Earth.
These signals come from the beginnings of the Universe, a period known as a dark era with no light-emitting stars, but hydrogen atoms emitting radio signals.
Not all instruments on Chinese probes, German scientists cooperate with their Chinese colleagues on the installation of particle detectors in the research vehicle, and the radio astronomy instrument on Quequiao satellite is a joint effort of China and the Netherlands.
4. Experiments with plants and worms
Probe wears capsules sealed with living species of Earth, including potato seeds and herbs called arabidopsis, as well as silkworm shells, with which China will try to create a lunar mini biosphere.
If Arabidopsis is blooming, the plant will produce "the first flower on the Moon," according to Chinese press.
Closed capsules allow the passage of sunlight so plants can perform photosynthesis.
The experiment, designed in collaboration with 28 Chinese universities, is a pioneering test of photosynthesis and breathing organisms in low lunar gravity, sixth of what is experienced on Earth.
Previous studies at the International Space Station have already shown that plants can grow well under micro-gravity conditions but experiment with biorcontrolled sphere on the Moon's surface.
The second difference is that the International Space Station is under the protection of so- Van Allen's belts, two radiation-generated areas that generate Earth's magnetic field.
But experiments on the moon can show growth to organisms without being protected from cosmic radiation.
