The average surface pressure is about 610 pascals (0.088 psi) which is 0.6% of the Earth's value. [2] The currently thin Martian atmosphere prohibits the existence of liquid water on the surface of Mars, but many studies suggest that the Martian atmosphere was much thicker in the past. [4]

Mars is approximately half the diameter of Earth, with a surface area only slightly less than the total area of Earth's dry land. [2] Mars is less dense than Earth, having about 15% of Earth's volume and 11% of Earth's mass , resulting in about 38% of Earth's surface gravity .
The rover used its Mastcam instrument to capture the area on the 4,352 Martian day of the pioneering mission. Images of the area from NASA’s Mars Reconnaissance Orbiter had shown light-colored ...
The THEMIS instrument, before being mounted onto Mars Odyssey. The Thermal Emission Imaging System (THEMIS) is a camera on board the 2001 Mars Odyssey orbiter. It images Mars in the visible and infrared parts of the electromagnetic spectrum in order to determine the thermal properties of the surface and to refine the distribution of minerals on the surface of Mars as determined by the Thermal ...
In the full-resolution color image, Earth was 90 pixels across and the Moon was 24 pixels across from a distance of 142 million km. [7] On May 25, 2008, HiRISE imaged NASA's Mars Phoenix Lander parachuting down to the surface of Mars. It was the first time that one spacecraft imaged the final descent of another spacecraft onto a planetary body.
The mole penetrator unit is designed to be placed near the lander in an area about 3-m long and 2-m wide. [21] The total mass of the system is approximately 3 kg (6.6 lb) and it consumes a maximum of 2 watt s while the mole is active. [7]
NASA artwork of a potential Mars habitat in conjunction with other surface elements on Mars Various components of the Mars Outpost proposal. (M. Dowman, 1989) [1] 1990s era NASA design featuring 'spam can' type habitat landers. The downside may be minimal shielding for the crew, and two ideas are to use Mars materials, such as ice, to increase ...
