Perseverance reached Mars for about $2.7 billion, while a crewed expedition could cost hundreds of billions because humans require years of life support, protection, supplies and a way home—although the frequently quoted $500 billion figure is only a rough historical estimate, not a settled NASA price tag.

Perseverance's Mars mission had a planned life-cycle cost of about $2.7 billion, covering a one-way robotic trip. A crewed Mars expedition would cost far more, since humans need years of life support, protection, supplies, and a return trip; the often-cited $500 billion figure is described as a rough historical estimate rather than a fixed NASA price tag.
Perseverance's planned $2.7 billion life-cycle cost covered a one-way robotic mission. A human Mars campaign adds years of life support, heavy landing, ascent and return, while old $500 billion figures describe broader programmes rather than a settled price for one expedition.
