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...

Cosmic Rays Origins
2013-08-30 11:25:08

[ Listen To The redOrbit.com Podcast: The Mystery Of The Origins Of Cosmic Rays ] John P. Millis, PhD for redOrbit.com - Your Universe Online Streaming across the Universe are high-energy charged particles, known as cosmic rays. They move through space, interacting with our galactic magnetic field, deflecting in every possible direction. Eventually these fast-moving particles may impact the Earth’s atmosphere. For more than 100 years astronomers have been aware of their existence,...

Mexico Observatory To Hunt For Gamma Rays In Known Universe
2013-08-22 07:35:15

April Flowers for redOrbit.com - Your Universe Online A new observatory has begun formal operations in Mexico. The High-Altitude Water Cherenkov (HAWC) Gamma Ray Observatory is designed to study the origins of very high-energy cosmic rays and observe the most energetic objects in the known universe. The HAWC uses a unique detection technique that is different from the classical astronomical design of mirrors, lenses, and antennae, making the extraordinary observatory a significant boost...

DNA Sequencing Microchip Tested For Trip To Mars
2013-07-09 11:11:13

Brett Smith for redOrbit.com - Your Universe Online As space agencies make plans to send scientific equipment to Mars, they must take into consideration the demands of a grueling trek across the solar system. The journey exposes spacecraft and their precious cargo to frigid temperatures and harsh solar radiation, meaning the often sensitive equipment onboard must be designed to handle these physical challenges. Aiming to build a system that excavates the Red Planet's surface for genetic...

Moon Radiation Study Reduce Health Risks Astronauts
2013-06-12 10:23:11

April Flowers for redOrbit.com - Your Universe Online A new study from the space scientists at the University of New Hampshire (UNH) and the Southwest Research Institute (SwRI) reports that data collected by NASA's Lunar Reconnaissance Orbiter (LRO) reveals that lighter materials like plastics provide effective shielding against the radiation hazards faced by astronauts during extended space travel. The findings, published in the journal Space Weather, could help reduce human health risks...

Extragalactic Ankle And Galactic Knee
2013-06-03 17:42:35

Karlsruhe Institute of Technology It is obvious from the data of the KASCADE-Grande experiment at the Karlsruhe Institute of Technology (KIT) that the so-called “knee” of the cosmic rays, a bend in the energy spectrum at high energies, is located at different energies for light and heavy particles. As regards light particles, the scientists have now found that the energy spectrum flattens again beyond the knee and forms a type of “ankle”. This structure indicates...

Radiation Dangers From Manned Mars Trip
2013-05-30 13:20:16

John P. Millis, Ph.D. and Lee Rannals for redOrbit.com — Your Universe Online There are many barriers that stand in the way of sending a human team to the surface of Mars. But near the top of the list of dangers would have to be the radiation exposure during the round trip voyage through the solar system. Clearly, a detailed understanding of the exposure levels is key in planning any mission to the Red Planet. To this end, the recent mission that carried NASA´s Curiosity...

New Cosmic Ray Telescope Hosted By Space Station
2013-03-12 15:44:52

University of Chicago The National Aeronautics and Space Administration has awarded $4.4 million to a collaboration of scientists at five United States universities and NASA´s Marshall Space Flight Center to help build a telescope for deployment on the International Space Station in 2017. The U.S. collaboration is part of a 13-nation effort to build the 2.5-meter ultraviolet telescope, called the Extreme Universe Space Observatory. UChicago Prof. Angela Olinto leads the U.S....

Where Do Cosmic Rays Come From?
2013-03-01 05:33:26

[ Listen to the Webcast ] John P. Millis, Ph.D. for redOrbit.com — Your Universe Online As we search the heavens, one of the striking observations is that we are constantly bombarded by a stream of extremely high energy charged particles, traveling at nearly the speed of light. Known as Cosmic Rays — composed mostly (90%) of protons with the rest mostly heavy nuclei and a small number of electrons — these particles appear to come from all directions. But where do...

Cosmic Rays -- Cosmic Rays. Cosmic rays are energetic particles that are found in space and filter through our atmosphere. Cosmic rays have interested scientists for many different reasons. They come from all directions in space, and the origination of many of these cosmic rays is unknown. Cosmic rays were originally discovered because of the ionozation they produce in our atmosphere. Cosmic rays also have an extreme energy range of incident particles, which have allowed physicists to...
