Image 1 - Watching Space Weather Through The MAGIC Of CubeSat CINEMA
2012-03-27 04:29:04

A trio of CubeSats that will study the effects of space weather on the Earth´s radiation belts and magnetic field are being prepared for launch. TRIO-CINEMA is a collaboration between UC Berkeley, Kyung Hee University and Imperial College London. The first CINEMA CubeSat passed acceptance testing in January 2012 and will launch in mid-2012. Two more identical spacecraft will launch towards the end of the year. The mission will be presented by Professor Tim Horbury at the National...

New System To Forecast Space Weather
2012-03-05 08:04:05

A new system has been developed by British scientists that will forecast space weather in an effort to better protect satellites orbiting our planet from damaging solar storms. Led by researchers at the British Antarctic Survey (BAS), the SPACECAST project is expected to provide reliable web-based forecasts so that satellite operators will be able to take action to keep their navigational, communication, and scientific satellites from the radiation that solar storms produce. Researchers...

Findings further efforts to better predict geomagnetic storms in space UCLA researchers have explained the puzzling disappearing act of energetic electrons in Earth's outer radiation belt, using data collected from a fleet of orbiting spacecraft. In a paper published today in the journal Nature Physics, the team shows that the missing electrons are swept away from the planet by a tide of solar wind particles during periods of heightened solar activity. "This is an important milestone...

Curiosity And The Solar Storm
2011-12-15 04:46:44

On Nov. 26th, Curiosity blasted off from Cape Canaveral atop an Atlas 5 rocket.  Riding a plume of fire through the blue Florida sky, the car-sized rover began a nine month journey to search for signs of life Mars. Meanwhile, 93 million miles away, a second lesser-noticed Mars launch was underway.  Around the time that Curiosity´s rocket was breaking the bonds of Earth, a filament of magnetism erupted from the sun, hurling a billion-ton cloud of plasma (a “CME”)...

Image 1 - Proba-1 Celebrates 10 Years Of Charting Earth's Radiation Belts

ESA´s Proba-1 recently celebrated its tenth birthday in orbit. Kept busy as an Earth-observing mission, the microsatellite has also been building a detailed picture of changes in our planet´s radiation belts. Smaller than a cubic meter, the technology-testing Proba-1 was launched on 22 October 2001. Among the payloads was ESA´s SREM standard radiation environment monitor, which was turned on a week later. The size of a shoebox, the monitor records high-energy charged...

For the first time, researchers have confirmed the existence of antimatter in the Earth's magnetosphere, BBC News reported on Sunday. Writing in Astrophysical Journal Letters, the researchers report that they discovered a thin band of antiprotons lying in between the inner and outer Van Allen radiation belts using the PAMELA (Payload for Antimatter Matter Exploration and Light-nuclei Astrophysics) satellite. Though the British news organization claims that only a small number of antiprotons...

The Van Allen radiation belts are a hazardous environment, full of 'killer' electrons that can be lethal to orbiting satellites. And when those electrons sometimes hit the atmosphere, they alter its chemistry with implications for climate variation. Now students at a school in Yorkshire are set to help scientists better understand the belts. Dr Andrew Kavanagh will present this innovative project between Lancaster University and Headlands School and Community Science College on Wednesday 20...

Scientists use innovative Radio Aurora Explorer satellite to discover conditions that cause disruptions in space-based communication and navigation signals Space weather-based disturbances in the Earth's upper atmosphere cause disruptions that affect space-based communication and navigation signals, such as GPS and radio signals. Radio Aurora Explorer (RAX) is a space weather research satellite that is designed to investigate the causes of these weather disturbances. RAX is the first...

They nicknamed it the "Little Balloon That Could." Launched in December of 2010 from McMurdo Station in Antarctica, the research balloon was a test run and it bobbed lower every day like it had some kind of leak. But every day for five days it rose back up in the sky to some 112,000 feet in the air. Down on Earth, physicist Robyn Millan was cheering it on, hoping the test launch would bode well for the success of her grand idea: launches in 2013 and 2014 of 20 such balloons to float in the...

Van Allen Radiation Belt -- The Van Allen radiation belt is a torus of energetic charged particles around Earth, trapped by Earth's magnetic field. The presence of a radiation belt had been theorized prior to the Space Age and the belt's presence was confirmed by the Explorer I on January 31, 1958 and Explorer III missions, under Doctor James Van Allen. The trapped radiation was first mapped out by Explorer IV and Pioneer III. Qualitatively, it is useful to view this belt as consisting...

endocarp
  • The hard inner (usually woody) layer of the pericarp of some fruits (as peaches or plums or cherries or olives) that contains the seed.
This word comes from the Greek 'endon,' in, within, plus the Greek 'kardia,' heart.
