Topic: Carbon Dioxide
In addition to better understanding the overall role of forests in the global carbon cycle, the scientists were also able to distinguish between the contributions of various forest types, confirming that among forests, tropical forests are those responsible for the largest component of global carbon fluctuations – both absorbing more carbon than other forest types, and releasing more carbon into the atmosphere due to deforestation and degradation. «Read the rest of this article» Sections: Technology | No Comments
NASA’s Mars Oxygen In-Situ Resource Utilization Experiment could one day provide Oxygen for Rockets
That’s a lot of propellant. But instead of shipping all that oxygen, what if the crew could make it out of thin (Martian) air? A first-generation oxygen generator aboard NASA’s Perseverance rover will test technology for doing exactly that. ![]() An illustration of MOXIE and its components. An air pump pulls in carbon dioxide gas from the Martian atmosphere, which is then regulated and fed to the Solid OXide Electrolyzer (SOXE), where it is electrochemically split to produce pure oxygen.

NASA’s OSCAR Project looks to convert Space Waste into useful Resources
As NASA prepares to return astronauts to the Moon and then venture to Mars, a lot of planning goes into how to keep crews safe and healthy and enable them to do as much science as possible. One of the challenges is how to handle trash. The Orbital Syngas/Commodity Augmentation Reactor (OSCAR) project, is an avenue to evolve new and innovative technology for dealing with garbage in space. «Read the rest of this article» Sections: Technology | No Comments
NASA’s Mars Curiosity Rover discovers information in Rocks about Mars’ cold, icy past
Weaving this story, element by element, from roughly 140 million miles (225 million kilometers) away is a painstaking process. But scientists aren’t the type to be easily deterred. Orbiters and rovers at Mars have confirmed that the planet once had liquid water, thanks to clues that include dry riverbeds, ancient shorelines, and salty surface chemistry. ![]() Filled with briny lakes, the Quisquiro salt flat in South America’s Altiplano represents the kind of landscape that scientists think may have existed in Gale Crater on Mars.

NASA’s Orbiting Carbon Observatory-2 measures Carbon Dioxide in Urban Areas
The study also demonstrates how satellite measurements of this powerful greenhouse gas can give fast-growing cities new tools to track carbon dioxide emissions and assess the impact of policy changes and infrastructure improvements on their energy efficiency. ![]() NASA’s Orbiting Carbon Observatory-2 (OCO-2) measures the amount of carbon dioxide in the atmosphere over areas like Las Vegas, Nevada, to help researchers better characterize the sources and sinks of the greenhouse gas.

NASA looks at returning to Venus
The image reveals a hellish landscape: a young surface with more volcanoes than any other body in the solar system, gigantic rifts, towering mountain belts and temperatures hot enough to melt lead. ![]() Venus hides a wealth of information that could help us better understand Earth and exoplanets. NASA’s JPL is designing mission concepts to survive the planet’s extreme temperatures and atmospheric pressure. This image is a composite of data from NASA’s Magellan spacecraft and Pioneer Venus Orbiter. (NASA/JPL-Caltech) «Read the rest of this article» Sections: Technology | No Comments
NASA Mars Curiosity Rover finds new mystery, Oxygen
As a result, they noticed something baffling: oxygen, the gas many Earth creatures use to breathe, behaves in a way that so far scientists cannot explain through any known chemical processes. Over the course of three Mars years (or nearly six Earth years) an instrument in the Sample Analysis at Mars (SAM) portable chemistry lab inside the belly of NASA’s Curiosity rover inhaled the air of Gale Crater and analyzed its composition. ![]() NASA’s Curiosity Mars rover imaged these drifting clouds on May 17, 2019, the 2,410th Martian day, or sol, of the mission, using its black-and-white Navigation Cameras (Navcams).

NASA Study reveals Amazon Drying Out due to Human Activities
Scientists at NASA’s Jet Propulsion Laboratory in Pasadena, California, analyzed decades of ground and satellite data over the Amazon rainforest to track both how much moisture was in the atmosphere and how much moisture was needed to maintain the rainforest system. «Read the rest of this article» Sections: Technology | No Comments
