(ORDO NEWS) — In 2019, China discovered a mysterious substance on the far side of the moon. But only after a long time, scientists were able to give an accurate answer about what it is.
In January 2019, China’s Chang’e-4 lunar probe became part of space history. It is the first spacecraft to make a soft landing on the mysterious far side of the moon.
Together with Chang’e-4, the Yutu-2 lunar rover also arrived on the satellite, which studied the rocky landscape for several months.
In the course of these explorations of the area, China said in September that the rover had stumbled upon an unusual gel-like substance at the bottom of the crater.
The strange material has been described as a “colored mystery substance”. Upon closer analysis, it became clear that the substance had a more glassy structure than a gel one, but its origin was still incomprehensible.
According to an article published in the journal Earth and Planetary Science Letters, a team of Chinese scientists were able to confirm their suspicions: the 50 by 15 cm material is most likely the result of melting due to meteor impacts.
Due to poor lighting, scientists were unable to fully understand the composition of the vitreous substance. But they were able to determine plagioclase, in an amount of about 38%. Which is quite normal for the moon.
The article also points out that the material is similar to two specific samples that were returned by NASA’s Apollo 15 and Apollo 17 missions.
