Martian weather between 3 June 2019 and 9 June 2019:

The MARCI acquires a global view of the red planet and its weather patterns every day. Please click and play the movie (.mp4 file) to see how the weather on Mars changed during this time.

Last week on Mars, dust storm activity continued along the edge of the receding seasonal north polar ice cap. Near the beginning of the week, a regional-scale dust storm occurred over the eastern Arcadia region and spread both southward to Amazonis and eastward towards the plains of Acidalia. As the storm slowly subsided during the second half of the week, dust haze pushed south towards the flanks of Olympus Mons. Focusing our attention to the southern hemisphere, sporadic local-scale dust storms were spotted over Sirenum, Aonia, and eastern Noachis Terra. Looking to the equatorial latitudes, condensate water-ice clouds remained present above the Tharsis Montes, Elysium Mons, and the plateaus near Valles Marineris. Throughout the week, skies persisted to be storm-free for both Curiosity in Gale Crater and InSight on Elysium Planitia.

About the Movie:
The movie (a .mp4 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 Science Laboratory rover, Curiosity (in Gale Crater) and the InSight lander (in Elysium Planitia). 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 movie.

Malin Space Science Systems (MSSS) built and operates the Mars Science Laboratory (MSL) Curiosity rover Mast Camera (Mastcam) and Mars Hand Lens Imager (MAHLI) and Mars Descent Imager (MARDI), the Mars Reconnaissance Orbiter (MRO) Mars Color Imager (MARCI) and Context Camera (CTX), and the Jupiter Orbiter (JUNO) camera (Junocam). 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, the suite of high resolution cameras aboard the 2009 Lunar Reconnaissance Orbiter (LRO), and Origins-Spectral Interpretation-Resource Identification-Security-Regolith Explorer (OSIRIS-REX) mission. MSSS is currently working on cameras for the Mars 2020 Rover mission.
