Pinkus' next project is a digital publication titled Terranes of Climate Change: Subsurface, Surface, Atmosphere.
Hayes' lab uses data from the Cassini RADAR instrument to study interactions between Titan's subsurface, surface, and atmosphere.
Specifically, Hayes is interested in using data from the Cassini RADAR instrument to study interactions between Titan's subsurface, surface, and atmosphere.
The presence of methane suggests ongoing exchange between the subsurface and the atmosphere of potentially biogenic trace gases, while the spatial and temporal variations cannot be accounted for with current knowledge of martian photochemistry.
Among the processes to be studied are the effects of regolith on transport from the subsurface to the atmosphere, the freezing point depression effects of dissolved nitrogen, and the solubility of various relevant organic compounds.
These hydrological systems are often interconnected, and surface water is also actively exchanged between the atmosphere and subsurface (i.e. groundwater).
These measurements also provide insight into the composition of the liquid found on Titan, allowing the researchers to better understand how the lakes and seas interact with the moon's atmosphere and subsurface.
With its liquids (both surface and subsurface) and robust nitrogen atmosphere, Titan's methane cycle is viewed as an analogy to Earth's water cycle, although at a much lower temperature.
Carrying instruments to study the atmosphere, surface, and subsurface, it entered Mars orbit on December 25; however, its British lander, Beagle 2, which was to examine the rocks and soil for signs of past or present life, failed to establish radio contact after having landed on the Martian surface the same day.
An additional property of Rn gas is its recoil energy, which enables it to migrate varying distances in porous and permeable media, thus allowing it to escape into the atmosphere from the subsurface.
