What was the title of C.S. Lewis's 1943 science-fiction novel about Ransom?

Out of the Silent Planet was C.S. Lewis’s 1943 science-fiction novel about Ransom. It is the first book in the series often called the Space Trilogy or Ransom Trilogy.

The protagonist, Elwin Ransom, is a philologist who is kidnapped and taken to the planet Malacandra, known as Mars in the novel’s setting. There he encounters intelligent species and learns that Earth is regarded as a fallen or corrupted world.

Lewis used the novel to challenge the morally bleak and technologically dominated ideas he associated with some modern science fiction. The book combines planetary adventure with Christian cosmology, language, and reflections on humanity’s place in the universe.

The next books in the trilogy are Perelandra, published in 1943, and That Hideous Strength, published in 1945. These titles are often confused with the first novel because all three follow Ransom’s wider story, but only Out of the Silent Planet begins his journey to Malacandra.
