Exploring the Red Planet is expensive. All previous missions cost billions of dollars. Perseverance is no different and NASA expects to spend \(2\.7 billion over the project's life\-cycle, according to research by The Planetary Society\. The bulk of that funding was put into the design and construction of the spacecraft itself which cost \)2.2 billion. Launch services for the Atlas V rocket cost \(243 million while the two years of prime mission operations are expected to work out at a further \)300 million. So how does that total compare with previous missions to Mars?
