Spaceship of the cosmonaut Petrov
Petrov is searching the orbit for asteroids, comets and other phenomena. Driven by the infiniteness and dangers of the universe, he calculates the orbit of the planets and tries to reach them with his home spacecraft.
He examines them, undauntedly, he takes samples in the form of core drillings. Being a mystic, he is propelled deeper and deeper into the space by more and more new phenomena and discoveries. In his logbook he tells about his adventures, he issues warnings and looks for solutions to ward off the dangers.
