Mr. Spaceship

by Philip K. Dick

"Mr. Spaceship" by Philip K. Dick is a science fiction novelette first published in 1953. Humanity wages a losing war against the Yuks, aliens who power their technology with living organisms rather than machines. When researcher Philip Kramer and his team create a spaceship controlled by a human brain—his dying professor's—they believe they've found the solution. But the professor has other plans, seizing control of the vessel to pursue his own vision for humanity's future.
