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...

Atmospheric Drag Impacts On Satellite Orbits
2013-09-12 04:13:35

redOrbit Staff & Wire Reports - Your Universe Online A beach ball-sized satellite designed to investigate the impact that atmospheric drag can have on satellite orbits is slated to be launched by NASA on Sunday, September 15. The satellite, which is known as the Drag and Atmospheric Neutral Density Explorer (DANDE), was designed and built by students at the University of Colorado Boulder. It will depart from Vandenberg Air Force Base in California and be carried into space aboard a...

No Planetary Influence On Solar Activity
2013-09-05 14:37:53

Lee Rannals for redOrbit.com - Your Universe Online New research in Astronomy & Astrophysics (A&A) is correcting errors in one statistical study published in the same journal last yea,r regarding the isotopic records of solar activity. Last year, astronomers wrote in the journal claiming that there is evidence of planetary influence on solar activity. However, the latest study refutes that claim, saying that they found no evidence of any planetary effect on the Sun. The Sun...

NASA's Goddard Space Flight Center Visitor Center in Greenbelt, Md. will host this month's Sunday Experiment on Sunday, Sept. 15 from 1 to 3 p.m. EDT. The Sunday Experiment is a free afternoon for children of all ages and their families to discover NASA Goddard's exciting missions. The Sept. 15 Sunday Experiment will explore NASA's Solar Dynamics Observatory (SDO) mission. SDO was launched in 2010, and is currently studying solar activity and how it causes space weather. Space weather...

Another Earth-Directed Coronal Mass Ejection
2013-08-22 06:59:09

NASA On August 21, 2013 at 1:24 am EDT, the sun erupted with an Earth-directed coronal mass ejection, or CME, a solar phenomenon that can send billions of tons of particles into space and reach Earth one to three days later. These particles cannot travel through the atmosphere to harm humans on Earth, but they can affect electronic systems in satellites and on the ground. Experimental NASA research models, based on observations from NASA’s Solar Terrestrial Relations Observatory show...

Solar Flip Soon
2013-08-06 13:41:02

Brett Smith for redOrbit.com - Your Universe Online [ Watch the Video: Preparing For The Solar Max Magnetic Flip ] Solar experts are anticipating a major event that is about to happen within the next three or four months - the sun is going to flip. Every eleven years, the Sun reaches the peak of its cycle and proceeds to switch polarity, making north become south and south become north. NASA scientists said the upcoming change will also mark the halfway point of solar max, a period...
