I wouldn’t be completely sold on the WAG argument, but again, here are the costs of a human, robot and Martian mission:
Human cost: $150 million – including an astronaut
Robot cost: $350,000 – including a rover and an astronaut
Martian cost: $150 million
The rover is the cheapest and the simplest option, while WAG is the most expensive option. There are various ways to build a WAG, depending on how quickly a mission might succeed (see below), how complicated a mission is, how difficult a landing will be (more complicated missions require more expensive options), and how much of a threat Mars poses to Earth.
There are also different ways to use the lander:
Mars Science Laboratory: (included in the mission)
A Mars Science Laboratory rover will cost $25 million – including an astronaut and a rovers.
A Mars Science Laboratory rover is a small, light, cheap, easy-to-use robot that will search for evidence of life. A Mars Science Laboratory rover will be used by NASA to find clues about if life ever existed on Mars in order to inform the public about life as we know it on Earth.
Rover cost: $6 million (including astronaut)
A rovers will be launched to the surface. These rovers are designed to explore the surface, gather data, perform tests, and send back pictures along the Martian surface. There are three types of rovers in development:
Spacecraft: A spacecraft is a reusable, multi-stage (orbital and cruise) vehicle that transports the astronauts. This is in contrast to lander, rover or habitat which all take separate flights from Earth.

Rover: A lander is like a rovers, but has a larger payload and larger diameter. A rover should be launched as one large orbit (that’s the size of Mars) and then travel back down to Earth.
