Martian weather between 2 June 2014 and 8 June 2014:

The MARCI acquires a global view of the red planet and its weather patterns every day. Please click and play the Quicktime movie (.mov file) to see how the weather on Mars changed during this time.

Dust activity on Mars picked up considerably this past week as expected based on observations from previous years. In the northern hemisphere, dust lifting occurred off the residual polar cap edge and was transported into Acidalia and northern Utopia as well as over the cap itself. Persistent local storm activity (storms with a duration of a day or two) was observed in the southern hemisphere throughout the week. Storms forming near the seasonal south polar cap edge in Aonia traveled north into Solis and contributed dust haze into the canyons of Valles Marineris before the haze was picked up by easterly circulation into Noachis. Storms were also observed in Cimmeria, Sirenum, Noachis, and Hellas. Diffuse water ice clouds forming the aphelion cloud belt remained present over much of equatorial Mars. Water ice clouds were also present in northern Utopia. A small dust cloud approached the south rim of Gale Crater but was only present for one sol, and the Curiosity rover site was otherwise relatively free of storms or clouds. Skies were cloudy but storm free over the Opportunity rover site at Endeavor Crater for most of the week. At the end of the week a storm was observed between Valles Marineris and Meridiani making atmospheric conditions dustier over the Opportunity rover site, however conditions were clearer than a smoggy summer day in Los Angeles.

About the Quicktime Movie:
The movie (a .mov file that you can click and play, above) was generated from images obtained by the Mars Color Imager (MARCI) onboard the Mars Reconnaissance Orbiter (MRO). During a nominal operational week, a total of about 273 MARCI images, taken in three of the camera’s seven color filter bands (420, 550, and 600 nanometer wavelengths), are map projected and mosaiced together to produce seven false-color daily global maps. These maps are then projected onto a sphere with north at the top and east to the right and with the mid-afternoon vantage point of an observer in the orbital plane (the imaginary plane that the planet draws out as it circles the Sun). Black areas in the movie are the result of data drops or high angle roll maneuvers by the spacecraft that limit the camera’s view of the planet. Equally-spaced blurry areas that run from south-to-north (bottom-to-top) result from the high off-nadir viewing geometry, a product of the spacecraft’s low-orbit, 250 km x 316 km (155 miles x 196 miles). The movie is rendered at a lower resolution than the intrinsic 1–2 km nadir resolution that the MARCI provides, so that it is practical to view and share via the Internet. The small white circles on these images of Mars indicate the locations of the Mars Exploration Rover, Opportunity (on Meridiani Planum), and the Mars Science Laboratory rover, Curiosity (in Gale Crater). Other locations on Mars referenced in the weather report can be found by referring to the map below. Note that the still image of Mars depicted at the top of this page is a single frame from the Quicktime movie.

Malin Space Science Systems (MSSS) built and operates the Mars Reconnaissance Orbiter (MRO) Mars Color Imager (MARCI) and Context Camera (CTX). MSSS also built and operated the Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC). In addition, MSSS built the Mars Odyssey (ODY) Thermal Emission Imaging Spectrometer (THEMIS) Visible (VIS) camera subsystem, which shares optics with the thermal infrared instrument and is operated at Arizona State University (ASU). MSSS also built the Mars Descent Imager (MARDI) for the Phoenix Mars Scout lander and the suite of high resolution cameras aboard the 2009 Lunar Reconnaissance Orbiter (LRO). MSSS is currently working on cameras for the 2011 Mars Science Laboratory (MSL) rover mission and the 2011 Juno Mission to Jupiter.
