The gravitational force of Mars is 38 percent of Earth's gravity. This low gravity is due to the fact that Mars only possesses 11 percent of the Earth's mass and 15 percent of the Earth's volume. The planet's significantly lower mass and size reduces the gravity it exerts on objects.
The Martian atmosphere is also much lower compared to Earth. The pressure that its atmosphere generates on the planet surface is approximately 7.5 millibars. By comparison, the Earth's atmosphere exerts 1,000 millibars of pressure. However, a day on Mars is very similar in length to an Earth day, with a Martian day being approximately 24 hours and 37 minutes.
