Morphology

mission + impossible

The meaning is directly compositional: 'mission' = a task/assignment and 'impossible' = cannot be accomplished, so together they denote a task that cannot (or is extremely difficult to) be achieved. This straightforward adjective-noun combination is cross-linguistically transparent and follows predictable English patterns, so a B1 learner who knows both words will readily infer the meaning.

Etymology

Mission impossible creates a strong image: a mission is an important task and impossible means it cannot be done, so the phrase feels like a job that will fail. Imagine a spy team given a task with no way to win, dangerous and very hard. That's why it means 'a task that is extremely difficult or almost impossible'.
