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]
The Mars Observer spacecraft, also known as the Mars Geoscience/Climatology Orbiter, was a robotic space probe launched by NASA on September 25, 1992, to study the Martian surface, atmosphere, climate and magnetic field.
The Mars Climate Orbiter (formerly the Mars Surveyor '98 Orbiter) was a robotic space probe launched by NASA on December 11, 1998, to study the Martian climate, Martian atmosphere, and surface changes and to act as the communications relay in the Mars Surveyor '98 program for Mars Polar Lander.
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 ...

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 ...
The Mars Orbiter Camera (MOC) operated by Malin Space Science Systems – The Mars Orbiter Camera (MOC), originally known as Mars Observer Camera, [9] [10] used 3 instruments: a narrow angle camera that took (black-and-white) high resolution images (usually 1.5 to 12 m per pixel) and red and blue wide angle pictures for context (240 m per pixel ...
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.
