c) cube

g) octahedron

Before you rejoice, think that a ability to solve the puzzle for the profession astronaut enough. To get a job in the European Space Agency, you have to first go to the European Astronaut Center in Cologne, where you teach science, mathematics, engineering, and medical skills, as well as orbital mechanics, the ability to survive and Russian language (for those who do not owns).

Subsequently, two and a half years of training in extreme conditions around the world, and only then, you may be able to fly into space.

But back to the puzzles.
