Spaceman of Bohemia is a sci-fi novel written by Jaroslav Kalfař in 2017. There are two parts of the story, and it is written from the point of view of Jakub Procházka, the first independent Czech Republic's astronaut. He is sent on a solo mission in space to a cloud of "intergalactic dust" near the planet Venus that no other country is willing to risk sending their citizens to inspect. He leaves behind his wife for this 8-month mission. While alone, he meets a giant arachnid named Hanuš and becomes friends with him. Jakub wants to escape his past so desperately that he is willing to travel hundreds of millions of miles to be free from it.
