NASA-supported tool accelerates wildfire recovery

NASA-supported tool accelerates wildfire recovery
Burned Area Emergency Response teams— they may be one of most important parts of wildfires that you've probably never heard of. As the last flames of a raging wildfire are being contained, these BAER crews begin safeguarding lives, property, and natural resources threatened by additional perils that fires create. "Wildfire reduces or removes vegetation and ground cover protecting forest soils," said Mary Ellen Miller, a research engineer from Michigan Tech Research Institute.

Human activity may affect space weather

Human activity may affect space weather
Our Cold War history is now offering scientists a chance to better understand the complex space system that surrounds us. Space weather - which can include changes in Earth's magnetic environment - are usually triggered by the sun's activity, but recently declassified data on high-altitude nuclear explosion tests have provided a look at the mechansisms that set off perturbations in that magnetic system.

NASA confirms biofuels reduce jet engine pollution

NASA confirms biofuels reduce jet engine pollution
Using biofuels to help power jet engines reduces particle emissions in their exhaust by as much as 50 to 70%, in a new study conclusion that bodes well for airline economics and Earth's environment. The findings are the result of a cooperative international research program led by NASA and involving agencies from Germany and Canada, and are detailed in a study published in the journal Nature.

NASA supercomputer shows CO2 in the atmosphere

NASA supercomputer shows CO2 in the atmosphere
A NASA supercomputer project builds on the agency's satellite measurements of carbon dioxide and combines them with a sophisticated Earth system model to provide one of the most realistic views yet of how this critical greenhouse gas moves through the atmosphere. Scientists have tracked the rising concentration of heat-trapping carbon dioxide for decades using ground-based sensors in a few places.

Ensuring you get your 5-a-day on Mars

Around this time of year the farmers down on earth will be planting away their crops ready for harvest, and so are the Astronauts up in space. In particularly the Astronauts aboard the International Space Station are planting their third on-orbit crop of red romaine lettuce. The Veg-03 experiment was initiated by NASA astronaut Shane Kimbrough, one of his first science assignments as a new crew member aboard the orbiting laboratory.

NASA to shine lasers on future aircraft concept

NASA to shine lasers on future aircraft concept
As NASA aeronautics engineers prepare to develop a series of greener, quieter, faster X-planes, they are already testing concepts that could be candidates. One of those is a Blended Wing Body (BWB). A 6% scale model of a Boeing BWB is being tested for six weeks in the 14x22ft. Subsonic Tunnel at NASA's Langley Research Center in Hampton, Virginia.

NASA works to improve solar electric propulsion

NASA works to improve solar electric propulsion
NASA has selected Aerojet Rocketdyne of Redmond, Washington, to design and develop an advanced electric propulsion system that will significantly advance the nation's commercial space capabilities and enable deep space exploration missions, including the robotic portion of NASA’s Asteroid Redirect Mission (ARM) and its Journey to Mars.

NASA selects instruments to study air pollution

NASA selects instruments to study air pollution
NASA has selected two proposals for new Earth science investigations that will put new instruments in low-Earth orbit to track harmful particulate air pollutants and study the development of tropical cyclones. Observations of small atmospheric aerosols from the MAIA will be combined with health information to determine the toxicity of different particulate matter types in airborne pollutants over the world's major cities. David Diner of NASA's JPL in Pasadena, California, is the principal investigator.
