An NJIT physicist is a collaborator in the discovery of a new structure in Earth’s inner radiation belt -- a zebra-striped structure of highly energized electrons that could endanger humans in space and also damage low-earth navigation and communication satellites. Newark, NJ (PRWEB) March 19, 2014 An NJIT physicist is a collaborator in the discovery of a new structure in Earth’s inner radiation belt -- a zebra-striped structure of highly energized electrons that could endanger humans...

Decades-old Mystery In Earth's Upper Atmosphere Solved
2013-12-18 14:51:49

University of California - Los Angeles New research published in the journal Nature resolves decades of scientific controversy over the origin of the extremely energetic particles known as ultra-relativistic electrons in the Earth's near-space environment and is likely to influence our understanding of planetary magnetospheres throughout the universe. Discovering the processes that control the formation and ultimate loss of these electrons in the Van Allen radiation belts — the rings...

Radiation Hazards Of Deep Space Travel Quantified By Researchers
2013-11-19 09:06:48

April Flowers for redOrbit.com - Your Universe Online Comprehensive findings on space-based radiation as measured by a detector aboard NASA’s Lunar Reconnaissance Orbiter (LRO) have been published by a team of scientists led by the University of New Hampshire. The findings, published in a special edition of Space Weather, provide critical information on the radiation hazards that will be faced by astronauts on extended missions to deep space such as those to Mars. The findings...

Prairie View A&M And NASA Goddard Collaborate On Radiation Effects Research
2013-11-04 13:54:06

NASA When Alvin Boutte presented his graduate work at the 2010 National Society of Black Engineers (NSBE) Aerospace Systems Conference in Los Angeles, Calif., he had no idea that he was about to connect with someone that would be instrumental in guiding his career. In attendance was Anthony Sanders from the Applied Engineering and Technology Directorate (AETD) at NASA’s Goddard Space Flight Center, Greenbelt, Md. The radiation engineering work that Boutte did at Prairie View A&M...

Space Weather Damaging Satellites
2013-09-16 14:32:14

Lee Rannals for redOrbit.com - Your Universe Online Scientists say space weather could be causing some satellite malfunctions due to high-energy electrons. Space weather is a biproduct of solar activity. When an eruption takes place on the sun's surface, it ejects charged particles which sometimes head straight towards Earth. MIT researchers writing in the journal Space Weather say this phenomenon is causing some geostationary satellites to experience failures despite efforts to protect...

ESA Opens New Space Weather Center In Brussels To Keep Their Eyes On Our Sun
2013-04-05 13:48:27

ESA This week, ESA opened a new Space Weather Coordination Centre to gather up-to-date information on our Sun. It is the first such data coordination center opened under the Agency´s Space Situational Awareness Programme. The new Space Situational Awareness (SSA) Space Weather Coordination Centre (SSCC) will serve as the central access point to a portfolio of European space-weather expertise for customers, including satellite operators, industrial sectors including...

Space Radiation Forecasts In Real Time
2012-10-16 14:06:24

Lee Rannals for redOrbit.com - Your Universe Online Astrophysicists have created the first online system for predicting and forecasting the radiation environment in near-Earth, lunar, and Martian space environments. The University of New Hampshire's Space Science Center (SSC) astrophysicists created the near real-time tool to provide critical information for potential manned missions to the moon and Mars. "If we send human beings back to the moon, and especially if we're able to go...

Cosmic Rays Alter Chemistry Of Lunar Ice
2012-03-20 02:52:10

Space scientists from the University of New Hampshire and multi-institutional colleagues report they have quantified levels of radiation on the moon's surface from galactic cosmic ray (GCR) bombardment that over time causes chemical changes in water ice and can create complex carbon chains similar to those that help form the foundations of biological structures. In addition, the radiation process causes the lunar soil, or regolith, to darken over time, which is important in understanding the...


Word of the Day
barratry
  • The offense of persistently instigating lawsuits, typically groundless ones.
  • An unlawful breach of duty on the part of a ship's master or crew resulting in injury to the ship's owner.
  • Sale or purchase of positions in church or state.
This word ultimately comes from the Old French word 'barater,' to cheat.
