The Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) meteorological staff at Malin Space Science Systems (MSSS) presents the following weather forecast and weekly weather reports for the landing sites of NASA's Mars Exploration Rovers (MER) and ESA's Beagle 2. MOC acquires images of the 3 landing sites and their surroundings every day. Weekly weather reports will be updated throughout the course of each lander mission. The landing sites are:

Isidis Planitia -- Beagle 2 -- reached Mars on 25 December 2003 (UTC) -- 24 December 2003 (PST)



Gusev Crater -- Spirit (MER-A) -- landed on 4 January 2004 (UTC) -- 3 January 2004 (PST)



Meridiani Planum -- Opportunity (MER-B) -- landed on 25 January 2004 (UTC) -- 24 January 2004 (PST)

Since March 1999, the MGS MOC has provided almost uninterrupted daily global observations of the Martian surface and weather in two colors (red and blue), at a resolution of 7.5 km/pixel (4.66 miles/pixel), during the early afternoon hours (2 PM local time). The two colors allow scientists to distinguish between different meteorological events, such as dust storms (pinkish-brown) and water ice clouds (white). With over 2.5 Mars years of observations, local and regional weather patterns have become well-known. Many weather patterns have a very strong tendency to repeat at about the same time and same place from year to year--- in other words, the weather is more predictable than for most places on Earth. This repeatability is not surprising. Martian weather conditions are controlled by several factors that do not change much from year to year: seasonal heating from the sun, recession of the seasonal polar frost, and topographic relief. It is therefore possible to use MGS MOC observations made in two consecutive years to generally forecast weather conditions at any given location for an interval not larger than about a week or so. Thus, the forecast---see link below---is based on the observations of martian weather made by MOC over the past two and a half Mars years.

Malin Space Science Systems and the California Institute of Technology built the MOC using spare hardware from the Mars Observer mission. MSSS operates the camera from its facilities in San Diego, CA. The Jet Propulsion Laboratory's Mars Surveyor Operations Project operates the Mars Global Surveyor spacecraft with its industrial partner, Lockheed Martin Astronautics, from facilities in Pasadena, CA and Denver, CO.
