It's the weight on Earth. Just look for a source that specifies in kg - there's no ambiguity about what the SI unit represents.

No, ambiguity was introduced when the measurement was switched from force to mass. The question remains: what is the weight/force experienced on the wheels on Mars? Knowing the mass won't tell us unless we also know the acceleration due to gravity on Mars.
