NASA Drone Could Help Detect Wildfires in Refuge

Posted on by

A camera-equipped lightweight drone could soon be helping federal officials spot forest fires in the nearly 112,000-acre Great Dismal Swamp National Wildlife Refuge along the Virginia-North Carolina border. NASAs Langley Research Center and the U.S. Fish and Wildlife Service have signed a one-year agreement to test small unmanned drones for the detection of brush and forest fires. NASA Langley got the drones for free from the U.S. Army and equipped them with infrared and visual cameras.

According to Mike Logan, the research lead at NASA Langley, an unmanned aerial vehicle costs much less to operate than a human piloted aircraft and can be used much more frequently and sooner to try to spot fires, like right after a thunderstorm passes. Actual flights over the swamp should begin before the end of the year. That will give operators enough experience to be proficient by the start of next fire season in the spring. It's not the first time drones have been used to help fight forest fires. For example, a Predator drone was used to provide aerial views of the massive Rim fire around Yosemite National Park in the summer of 2013.

NASA Selects Advanced Oxygen Recovery Proposals for Spacecraft Missions

Posted on by

NASA has selected four partners to develop game changing technologies with the potential to increase the oxygen recovery rate aboard human spacecraft to at least 75 percent while achieving high reliability. These oxygen recovery and recycling technologies will drive exploration and enable our human journey to Mars and beyond.

"Improving oxygen recovery while achieving high reliability is critical for any long-duration human spaceflight missions where oxygen resupply from Earth isn't available," said NASA Associate Administrator for Space Technology Michael Gazarik. "NASA recognizes that sustained technology investments must be made to mature the capabilities required to reach the challenging destinations that await exploration; such as cis-lunar space, an asteroid, and Mars. These ambitious projects will enable the critical life support systems needed for us to venture further into space and explore the high frontier and are another example of how technology drives exploration."

Phase I awards are up to $750,000, providing awardees with the funding for 15 months to complete the engineering development unit hardware phase. Technologies selected to continue to Phase II will develop prototype hardware with NASA support that provides up to $2 million per award for up to 24 months.

The organizations selected to work on the development of advanced life-support technologies are:

Future maturation of these technologies may use the International Space Station National Laboratory as a proving ground to retire risk and gain experience with capabilities needed for deep-space exploration.

The advanced technologies found in these proposals are called for in the agency's space technology roadmaps and space technology strategic investment plans. The National Research Council's "NASA Space Technology Roadmaps and Priorities" identified long-duration environmental control and life support systems as one of the top five areas capable of having the greatest impact on deep space exploration.

Proposals for this solicitation were received from NASA centers, universities, research groups and industry. These awards are managed by the Game Changing Development Program within NASA's Space Technology Mission Directorate. NASA's Langley Research Center in Hampton, Virginia, manages the Game Changing Development Program.

During the next 18 months, NASA's Space Technology Mission Directorate will release several more solicitations, investing in high priority technology areas where advances are needed to achieve more capable, reliable and affordable science, exploration and commercial space capabilities.

NASA's Space Technology Mission Directorate remains committed to developing the critical, broadly applicable technologies required to enable future exploration missions beyond low-Earth orbit. The directorate continues to solicit the help of the best and brightest minds in academia, industry, and government to drive innovation and enable solutions in a myriad of important technology thrust areas. These planned investments are addressing high priority challenges for achieving safe and affordable deep-space exploration.

NASA Langley to use drone as fire-spotter over Great Dismal Swamp

Posted on by

In August 2011, lightning struck the Great Dismal Swamp and ignited a mammoth blaze that burned for 108 days, scorched 6,500 acres and blew choking smoke into surrounding states.

It was the biggest wildfire on record in Virginia history. And it sparked a eureka moment in nearby resident Mike Logan, who happens to lead the Small Unmanned Aerial Vehicle Lab at NASA Langley Research Center in Hampton.

"I made a phone call to the local fire captain after inhaling days of peat bog smoke," Logan said in a release Tuesday. "I learned most fires are caused by lightning strikes, and the only way they can spot them is by hiring an aircraft to do an aerial survey of the huge swamp. So I figured why not use a UAV or drone as a fire detector?"

Now the NASA center has joined with the U.S. Fish and Wildlife Service of the Department of the Interior on a year-long project to test Logan's idea.

Proponents of UAVs have long promoted the idea of using unmanned aircraft as fire-spotters. Chris Lowie, manager of the Great Dismal Swamp refuge, said Fish and Wildlife is evaluating whether drones can offer a "safe and more cost-effective alternative for surveillance" of vulnerable areas, particularly after a thunderstorm.

The refuge has experienced lightning-induced fires throughout its history. Before the 2011 blaze, another had struck in 2008. Each cost $10 million to extinguish.

Lowie said they hope to see not only a "significant decrease" in the time it takes to scout for fires but in the cost to battle them.

The Federal Aviation Administration must approve the project, NASA says. Once it does, engineers will install cameras and transmitters on a lightweight former U.S. Army target drone and send it on scouting missions over the refuge.

According to NASA, the drone weighs 50 pounds and has a nearly 6-foot wingspan. It has an 8-mile range and can fly for about an hour under battery power. It can be pre-programmed to fly autonomously, but a pilot will still monitor operations during the test period.

According to NASA Langley spokeswoman Katherine Barnstorff, actual flights should begin by year's end so crews can get proficient in the technology before the start of the spring fire season. A refuge fire management team will monitor the flight video, and NASA engineers will monitor and program the drone.
