Recurring Slope Lineae: Shallow subsurface flowing water on Mars - David...
Δημοσιεύτηκε στις 7 Οκτ 2014
Abstract: Recurring Slope Lineae
(RSL) are narrow (0.5 to 5 m) dark albedo features that incrementally
lengthen down steep slopes and reoccur each year. RSL are well
correlated with temperature, as they lengthen as temperature increases
and fade as temperature decreases. RSL have been observed within a
latitude band from 37°N to 52°S, but tend to cluster in the southern
mid-latitudes (SML) in and around Valles Marineris and Chryse Planitia.
In this talk, Dr. Stillman will demonstrate how observations from the
~25 cm/pixel High Resolution Imaging Science Experiment (Hi-Rise)
onboard Mars Reconnaissance Orbiter and surface temperature data
acquired by three orbital instruments suggest that RSL are caused by
subsurface liquid water flows.
