The early universe was and remains a mystery to the scientists. How was it formed, how did it develop and what stages of its evolution existed? The researchers are trying to find the answers to these and other questions. Theoretical assumptions that allow a glimpse into the history of the universe are supported by practical actions. One of the daring plans that will allow us to learn much more about the early Universe than the astronomers know, is related to the upcoming mission of NASA.

It is assumed that a spacecraft will be directed to the far side of the Moon that will be able to look in the very first days of the formation of the ancient Universe. That mission is implemented by NASA and the National Radio Astronomy Observatory, NRAO.


The spacecraft will be launched so that it can land on the dark side of the Earth's satellite. The device, called DAPPER, has to look for certain radio signals. They were published by the Universe during the so-called dark ages. Their period dates back about 380 thousand years after the Big Bang.

At that moment, there were no stars or galaxies that could illuminate the Universe. If the spacecraft installed on the far side of the Moon is lucky enough to detect these signals, then their decoding will give modern science a new level of understanding of the development of the Universe and the formation of stars and planets.

The task is complicated by the fact that any early signals from space are extremely weak. Therefore, the DAPPER device has to go all the way to the dark side of the satellite in order to block all radio transmissions from the Earth, and thus catch the distant and barely distinguishable signals of the ancient Universe.


Not a single telescope installed on the Earth will be able to cope with this task. Technically, no device is capable of measuring and confirming the very weak signal of neutral hydrogen from the early Universe, because there are so many other bright and strong signals that interrupt possible weak ones.

So does the lead researcher of the NASA mission, Richard Bradley, say. While the spacecraft is in development and only in 2-3 years will it be ready for launch.
