MARCI weather report, January 22-28, 2018
The prevalence of water-ice clouds was strong across many regions of Mars last week. The aphelion cloud belt continued to rule the skies along the tropics. Poleward of Alba Patera, remainders of a recurring annular (ring-shaped) cloud were visible in … Continue reading

MARCI weather report, January 15-21, 2018
Last week on Mars, a number of small transient dust storms were spotted over Solis Planum. Looking slightly northwards, the water-ice clouds of the aphelion cloud belt continued to dominate the afternoon skies. The northern plains were at a continued … Continue reading

Hydrogen escape from atmosphere linked to global dust storms
Some Mars experts are eager and optimistic for a dust storm this year to grow so grand it darkens skies around the entire Red Planet. This biggest type of phenomenon in the environment of modern Mars could be examined as … Continue reading

How the solar wind interacts with Mars
Mars, without a strong internal dipole magnetic field, is a place where the supersonic solar wind directly contacts the planet’s upper atmosphere. Using a large set of data from the Mars Atmosphere and Volatile EvolutioN (MAVEN) mission, [a paper published … Continue reading

MARCI weather report, January 8-14, 2018
Last week, the red planet experienced weather conditions comparable to that of the preceding week. The plateaus of Solis and Syria both experienced short-lived local-scale dust storms. Along the equatorial latitudes, the aphelion cloud belt persisted each afternoon. Looking northward, … Continue reading

MARCI weather report, January 1-7, 2018
Small transient dust storms were spotted over Solis and Syria Planum this past week. The aphelion cloud belt, comprised of condensate water-ice clouds, dominated the equatorial latitudes all week. Apart from dust haze over some areas, dust-lifting activity was diminished … Continue reading

MARCI weather report, December 25-31, 2017
Weather features on the red planet were very similar to the previous week. The aphelion cloud belt, formed of diffuse water-ice clouds, persisted over the tropics. Focusing further southward, local-scale dust storms were observed over Solis Planum and western Noachis. … Continue reading

MARCI weather report, December 11-17, 2017
Last week, a couple of small transient dust storms were spotted near the edge of the north polar cap, which had already reached its perennial configuration. Looking further south to the tropics, the aphelion cloud belt continued to be the … Continue reading

Mars atmosphere well protected from solar wind
Despite the absence of a global Earth-like magnetic dipole, the Martian atmosphere is well protected from the effects of the solar wind on ion escape from the planet. New research shows this using measurements from the Swedish particle instrument ASPERA-3 … Continue reading
