Mars in a Minute: How Do You Land on Mars?

Explain why it is your weight and not your mass that would change if you landed on Mars.

Why is life not possible on Venus and Mars?

The mean diameters of Mars and Earth are 6.9 xx 10^3 km and 1.3 xx 10^4 km, respectively. The mass of Mars is 0.11 times Earth's mass. (a) What is the ratio of the mean density (mass per unit volume) of Mars to that of Earth? (b) What is the value of the gravitational acceleration on Mars? (c) What is the escape speed on Mars?

Bauxite (Al_(2)O_(3).2H_(2)O) and Aluminosilicate both are ores of aluminium. Bauxite is found on earth but not on Mars whereas Aluminosilicate is found on earth as well as Mars. Possible reason is:

In the echo method of estimating distnces, a radar signa was sent towards the Mars. If the echo was received after 8 minute 20 second, how far wat the Mars from the earth at that instant?

How is our atmosphere different from the atmospheres on Venus and Mars?

Compare the period of rotation of planet Mars about the sun with that of the earth. The mean distance of the Mars from the sun is 1.52 AU.

The radius of the Earth is about 6400 km and that of Mars is about 3200 km. The mass of the Earth is about 20 times the mass of Mars. An object weighs 500 Non the surface of Earth. Its weight on the surface of Mars would be
