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
when it gets there.

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.
Mars has a mass of 6.42 x 10^23 kilograms. The weight of Mars would vary depending on the gravitational pull it is subjected to.
Which one? There have been two, you need to specify the one you are asking about.
Sorry, there've been FOUR, not two!
On Mars, gravity is about 38% of Earth's gravity. If you weigh 90 pounds on Earth, you would weigh around 34.2 pounds on Mars.
98 pounds on Mars would weigh approximately 37.1 pounds due to the weaker gravity on Mars compared to Earth.
On Mars, you weigh 37.7% as much as you would on Earth. If you weigh 100 pounds on Earth, you weigh only 37.7 pounds on Mars. If you weigh 150 pounds on Earth, you weigh only 56.6 pounds. The equation is .37 x Earth weight = Martian weight.
On Mars, an object weighing 125 pounds on Earth would weigh approximately 47.5 pounds, due to Mars having only 38% of the gravity of Earth.
Gravitational acceleration at Mars' surface = 3.7 m/sec2 = (3.7/9.8) = 0.3776 of its value at earth's surface.An object that weighs 115 on earth would weigh [ 115 x (3.7/9.8) ] = 43.418 on Mars. (rounded)
