NASA Firestation To Track Strange Things Produced By Thunderstorms
2013-09-11 12:32:12

[ Watch the Video: Firestation To Investigate Thunderstorm Tops ] Lee Rannals for redOrbit.com - Your Universe Online A new experiment aboard the International Space Station (ISS) is looking into the strange things that come from the tops of thunderstorms. The experiment, called "Firestation" consists of a package of sensors designed to explore how the Earth mimics a supernova during thunderstorms. About 50 times a second bolts of lightning heat up the air to a temperature five times...

Researchers Explore Dark Lightning
2013-04-11 10:57:42

April Flowers for redOrbit.com - Your Universe Online A group of researchers from Florida Institute of Technology's Department of Physics and Space Science recently asked the somewhat unusual question: "What are the radiation doses to airplane passengers from the intense bursts of gamma-rays that originate from thunderclouds?" Faculty members Joseph Dwyer, Ningyu Liu and Hamid Rassoul discussed the question and their answers concerning terrestrial gamma ray flashes at a press conference...

NASA Gives Fermi Space Telescope Better Vision
2012-12-06 15:31:34

[Watch Video: Fermi Finds Radio Bursts From Terrestrial Gamma-Ray Flashes] Lee Rannals for redOrbit.com — Your Universe Online NASA's Fermi Gamma-ray Space Telescope is new and improved, and ready to start sending back some images of high-energy light mysteriously produced above thunderstorms. The space agency updated the telescope with improved data analysis techniques and a new operating mode to the Gamma-ray Burst Monitor (GBM) aboard Fermi. This will enable the...

WASHINGTON, Dec. 6, 2012 /PRNewswire-USNewswire/ -- Thanks to improved data analysis techniques and a new operating mode, the Gamma-ray Burst Monitor (GBM) aboard NASA's Fermi Gamma-ray Space Telescope is now 10 times better at catching the brief outbursts of high-energy light mysteriously produced above thunderstorms. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) The outbursts, known as terrestrial gamma-ray flashes (TGFs), last only a few thousandths of a second, but...

Tiny 'Firefly' Satellite Used To Flash Straight Into Lightning and Thunderstorms
2012-07-20 15:50:45

'CubeSat' will help solve mysteries of terrestrial gamma ray flashes, 1,000 times more powerful than 'northern lights' Imagine a fully-instrumented satellite the size of a half-gallon milk carton. Then imagine that milk carton whirling in space, catching never-before-seen glimpses of processes thought to be linked to lightning. The little satellite that could is a CubeSat called Firefly, and it's on a countdown to launch next year. CubeSats, named for the roughly four-inch-cubed...

RHESSI Mission Celebrates Ten Years And Forty Thousand X-Ray Flares
2012-02-11 04:00:56

[ Watch the Video ] On February 5, 2002, NASA launched what was then called the High Energy Solar Spectroscopic Imager (HESSI) into orbit. Renamed within months as the Ramaty High Energy Solar Spectroscopic Imager (RHESSI) after Reuven Ramaty, a deceased NASA scientist who had long championed the mission, the spacecraft's job was to observe giant explosions on the sun called solar flares. During a solar flare, the gas soars to over 20 million degrees Fahrenheit, and emits X-rays that...

Firestation In Space To Open Firehose Of Lightning Data
2011-10-18 09:49:22

When opportunity knocked, NASA heliophysicist Doug Rowland answered. He and his team recently secured another flight opportunity for a pint-sized instrument studying lightning in Earth's upper atmosphere and now are bracing for a veritable "fire hose" of data about a little-understood phenomenon first discovered by scientists nearly two decades ago. The instrument, Firestation, is one of four experiments manifested to fly on an experiment pallet the U.S. Department of Defense plans to...

NASA scientists have discovered beams of antimatter being produced by thunderstorms here on Earth--a phenomenon that had never been observed before, the US space agency said on Monday. It is believed that the antimatter particles were formed in a terrestrial gamma-ray flash, or TGF. According to a NASA press release, about 500 of these lightning-related events occur each day, but most of them are undetected. This one was spotted using NASA's Fermi Gamma-ray Space Telescope. "These signals are...

WASHINGTON, Jan. 10, 2011 /PRNewswire-USNewswire/ -- Scientists using NASA's Fermi Gamma-ray Space Telescope have detected beams of antimatter produced above thunderstorms on Earth, a phenomenon never seen before. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) Scientists think the antimatter particles were formed in a terrestrial gamma-ray flash (TGF), a brief burst produced inside thunderstorms and shown to be associated with lightning. It is estimated that about 500 TGFs...

Satellites are big. They cost a lot of money. At least that's the impression a couple of University of Maryland-College Park students had when they applied for an internship to help construct a satellite instrument with scientists at the NASA Goddard Space Flight Center in Greenbelt, Md. As the pair quickly discovered, nothing could have been farther from the truth. To their astonishment, the satellite that Saman Kholdebarin and Lida Ramsey helped to develop was literally the size of a...
