Each of the two rovers presently on the Martian surface has a mass of 174 kilograms.

That mass weighs 384 pounds on Earth, zero on the way to Mars, and 145 pounds

On Earth, the Spirit and Opportunity rovers each weigh about 408 lbs. Surface

gravity on Mars is 38% that of Earth, so each rover weighs about 155 lbs there.

The mass of Curiosity is 899 kilograms. That mass weighs 8,816 newtons (1,982 pounds)

on Earth and 3,336 newtons (750 pounds) on Mars.

Mars has a mass of 6.4185 × 1023 kg. If it were placed in gravitational field similar to Earth's it would weigh 6.4185 × 1023 kg, but it can't be so it doesn't. Another case of the weight of something not being the same as its mass.
