Instead of changing the entire makeup of Mars’ atmosphere, what if you could take a more localized, regional approach? Silica aerogel: extremely high insulation domes Intheir paper— published today, July 15, inNature Astronomy— the researchers outline how regions of the Red Planet could b...
Using an advanced computer model, the team simulated the potential atmospheric composition of early Mars to explore the potential for formaldehyde production. The model was built with the assumption that the atmosphere was rich in carbon dioxide, hydrogen, and carbon monoxide. Their simulations suggest...
The Atmosphere of Mars near the Surface: Isotope Ratios and Upper Limits on Noble Gases Several new analyses of the martian atmosphere have been carried out with the mass spectrometer in the molecular analysis experiment. The ratios of abundan... K Biemann,T Owen,DR Rushneck,... - 《Scienc...
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. A Joint Instrument Definition Team (JIDT) was asked to ...
One explanation is the presence of high concentrations of greenhouse gases, but which one(s) are (as usual) a subject of controversy. Some researchers suggest a carbon dioxide (CO2) atmosphere, (Ohmoto et al., 2004) while others are proponents of a methane (CH4) haze. (Arney et al., ...
Likewise, the exsolution of S-bearing phases such as H2S into the atmosphere during hydrothermalism would readily explain the absence of S enrichment in the area. The expectation that Al would resist leaching is realized with the presence of some high Al values in the area despite typically ...
Cultural Information Greenhouse Effect The greenhouse effect is a process by which thermal radiation from a planetary surface is absorbed by atmospheric greenhouse gases, and is re-radiated in all directions. Since part of this re-radiation is back towards the surface and the lower atmosphere, it ...
This is especially important because it is essentially an early image of the solar system's earliest moments. And, because the Ryugu sample was studied so carefully, without exposing the sample to the Earth's atmosphere and instead of studying it in a sealed environment filled with purified nitr...
, through its UK veterinary group Linnaeus and in partnership with Waltham Petcare Science Institute, today announced a first-of-its-kind partnership with SageTech Veterinary to pilot an innovative anaesthetic gas capture solution to help prevent harmful green...
Big "splashes" like these would have hurtled large volumes of atmosphere into space, while also introducing water and other material to the surface. Artist's concept: Disappearance of the ancient magnetic field may have triggered the loss of the Martian atmosphere. (Image credit: NASA) However,...
