The study, led by researchers at the Georgia Institute of Technology, found brown carbon particles released into the air from burning trees and other organic matter are much more likely than previously thought to travel to the upper levels of the atmosphere, where they can interfere with rays from the sun – sometimes cooling the air and at other times warming it. ![]() Brown carbon particles produced by wildfires such as the ones that have scorched parts of Georgia and Florida this year are more likely than previously thought to travel to the upper levels of the atmosphere and impact climate.

NASA’s Mars Reconnaissance Orbiter confirms Liquid Flowing Water on MarsWritten by Guy Webster / DC Agle
Using an imaging spectrometer on MRO, researchers detected signatures of hydrated minerals on slopes where mysterious streaks are seen on the Red Planet. These darkish streaks appear to ebb and flow over time. They darken and appear to flow down steep slopes during warm seasons, and then fade in cooler seasons. They appear in several locations on Mars when temperatures are above minus 10 degrees Fahrenheit (minus 23 Celsius), and disappear at colder times. ![]() Dark, narrow streaks on Martian slopes such as these at Hale Crater are inferred to be formed by seasonal flow of water on contemporary Mars. The streaks are roughly the length of a football field. (NASA/JPL-Caltech/Univ. of Arizona) «Read the rest of this article» Sections: Technology | No Comments

NASA’s Jet Propulsion Laboratory CubeSat program provides big satellite performance in a small packageWritten by DC Agle
From designing the spacecraft, the mission proposal and the circuit boards to testing the flight software and putting together budgets, sending something, anything, into the cosmos depends on good people who know their job. “Although significantly smaller in size, CubeSats contain analogous payloads and subsystems to larger satellites and require similar technical knowledge and resources to traditional flight projects,” said Shannon Statham, an engineer at NASA’s Jet Propulsion Laboratory in Pasadena, California. “The training and experience gained by working on CubeSats are directly applicable to larger missions.” ![]() Team RACE: Fifteen JPL Early Career Hires (recently graduated engineers and scientists) worked closely together to get the Radiometer Atmospheric CubeSat Experiment (RACE) ready for flight.

NASA’s Mars Reconnaissance, Odyssey orbiters discover Martian Slopes where Water possibly flowedWritten by Guy Webster
The features are dark, finger-like markings that advance down some Martian slopes when temperatures rise. The new clues include corresponding seasonal changes in iron minerals on the same slopes and a survey of ground temperatures and other traits at active sites. ![]() This image combines a photograph of seasonal dark flows on a Martian slope with a grid of colors based on data collected by a mineral-mapping spectrometer observing the same area.
