The experts examined the crater wall, and collected samples of gases, rocks and ice.
« We made only the first step in the study of the subject. Foundation has been laid, now need to treat the extracted material, develop a plan for further research will have to use a number of methods, drilling, “- said Alexander Kizyakov scientist of the Department Cryology MSU.
