Abstract Observations with sensitive photodiode detectors on the Perseverance rover (Hueso et al., 2023, https://doi.org/10.1029/2022JE007516 ; Vicente‐Retortillo https://doi.org/10.1029/2022je007672 ) to detect dust devils and track formation, movies of Ingenuity helicopter's downwash impingement Martian surface (Lemmon 2022a, https://doi.org/10.1029/2022je007605 Lemmon 2022b, https://doi.org/10.1029/2022gl100126 ), together in‐situ meteorological data, give new insights into important problem dust‐lifting Mars, a phenomenon which influenced lifetime recent rovers landers. These results, low‐gravity wind tunnel experiments parabolic flights interpretation large blast pattern from lander retrorockets, indicate that particle motion visible darkening Mars can result aerodynamic pressures only 1–5 Pa, considerably less than previously thought.

Effect of Atmospheric Dust on Interannual Variability in the Martian
Mars Observer Camera (MOC) observations from Mars Global surveyor (MGS) revealed that the Residual South Polar Cap (RSPC) consists of several units that show evidence of deposition and erosion with characteristic times on the order of ~ 100 years [1]. These authors suggested that significant changes observed in the RSPC between MY 9, when Mariner 9 observed the cap,, and MY 12, observed by Viki...
متن کاملMass of Dust in the Martian Atmosphere
1 Estimates of the mass of dust suspended in the Martian atmosphere are derived from global and regional 9 pm opacity maps produced from Viking Infrared Thermal Mapper data. During the peak of the 1977b storm, a total dust mass of approximately 101 S gm was suspended, equivalent to 10-3 gm/cm2, or a layer 4 Lm thick. During a local dust storm near Solis Planum at Ls 227°, approximately 3.56 x 1...
متن کاملON THE LIFTS OF SEMI-RIEMANNIAN METRICS
In this paper, we extend Sasaki metric for tangent bundle of a Riemannian manifold and Sasaki-Mok metric for the frame bundle of a Riemannian manifold [I] to the case of a semi-Riemannian vector bundle over a semi- Riemannian manifold. In fact, if E is a semi-Riemannian vector bundle over a semi-Riemannian manifold M, then by using an arbitrary (linear) connection on E, we can make E, as a...

Mukai (1992), Krymskii et al. (1992), Tátrallyay et al. (1992), Juhász et al. (1993), Kholshevnikov et al. (1993), In this paper, we present modeling results of the presumed dust belts of Mars. We combine recently obtained theoretical Ishimoto and Mukai (1994), Krivov (1994), Krivov and results in dynamics of circumplanetary dust grains with up-toTitov (1994), Sasaki (1994), Juhász and Horányi ...
متن کاملDetecting electrical activity from Martian dust storms
We present a model addressing the possible electrification of Martian dust storms based on the effective electrical charging of an individual dust grain. An upper charge bound on a grain can be determined based on the grain capacitance in the lowpressure Martian atmosphere. It is assumed that treiboelectric and inductive processes, like that presumed operating in terrestrial dust storms, can el...
