Which C.S. Lewis novel features the characters Ransom, Weston, and Devine on the planet Malacandra?

Out of the Silent Planet features Ransom, Weston, and Devine on the planet Malacandra.

Published in 1938, Out of the Silent Planet is the first novel in C.S. Lewis’s Space Trilogy. Its protagonist, Elwin Ransom, is kidnapped and taken to Malacandra, a planet that humans commonly call Mars. There he encounters intelligent species and begins to reconsider the assumptions brought from Earth.

The antagonists Weston and Devine represent contrasting forms of human ambition and exploitation. Lewis uses the story to explore colonialism, scientific power, language, morality, and the possibility of intelligent life beyond Earth. The novel’s speculative setting is paired with theological and philosophical questions.

The two sequels are Perelandra and That Hideous Strength. Their settings and plots differ substantially, so the characters and planet in this question identify the first volume specifically. Malacandra is the inhabitants’ name for the world, while “Mars” is the familiar Roman-derived name used by humans.
