Was Phobos downed by the Sun or a technical flaw?

Catastrophic Solar Flare Knocks Out Phobos?

Did a catastrophic Solar Flare knock out Russia’s Phobos satellite? The fall of Russia’s Phobos space probe might have been caused by a  solar flare, an intergovernmental commission reported to the Roskosmos state agency on Thursday. However, some experts have offered other versions of the crash. According to the commission, a cloud of plasma released during the November 4 solar flare remained active for the following 10 days and could have affected the probe’s launch. These experts believe that a technical or construction failure was … Continue reading

Solar flare disrupts flight communication

2012 solar flare disrupts flight communication

2012 Solar flare disrupts flight communication — and lights up night sky by David B. Nelson Jan 25, 2012 While 2012 prophets may interpret Sunday’s [January 22, 2012] massive solar flare activity as a sign of doomsday, scientists say not to worry, especially if you are lucky enough to catch a glimpse of the northern lights. But airlines are still urged to exercise caution. The flare was classified as a M8.7 Coronal Mass Ejection, a moderate event despite being called the biggest and strongest activity … Continue reading

Solar Flare May Have Caused Fobos-Grunt Failure

solar flare Fobos-Grunt satellite crash 2012

2012 Solar Flare Eyed in Fobos Satellite Crash Moscow Times 27 January 2012 A powerful solar flare may have caused the failure of the Fobos-Grunt space probe that crashed this month, a space industry source told Interfax on Thursday. The device may have ended up in a cloud of plasma released during the solar event, and this is the main theory being considered by the commission investigating the probe’s technical failure, the source said. The commission investigating the failure has completed its work and will … Continue reading

Solar flare space storm affects satellites and airlines

January 22, 2012 Solar Flare causes significant radiation storm but experts say most communication systems are unaffected Radiation from the largest solar flare in more than six years shouldn’t adversely affect communications or technology for most people on earth, experts say. Doug Biesecker, a physicist at the US Space Weather Prediction Center in Boulder, Colorado, said that while the solar flare has caused problems for some GPS systems, airline communications systems and satellites over the past day or two, most people around the world won’t … Continue reading

Solar storms may cause cellphones to drop calls

Solar Flare 2012 Cellphone catastrophe

On Sunday, January 22, 2012, a massive explosion on the sun known as a solar flare sent an ejection of some of the sun’s plasma hurtling toward earth at the ungodly speed of 1,000 kilometers…per second! No need to worry about being hit by flying sun plasma though — that will zoom right past Earth and race toward the edge of the solar system, according to Harlan Spence, principal investigator for the Cosmic Ray Telescope for the Effects of Radiation (CRaTER) instrument onboard NASA’s Lunar … Continue reading

Crab Pulsar gamma rays baffle scientists

Crab Pulsar gamma ray source

Scientists say the Crab Pulsar is blasting out gamma rays at a higher rate than can be explained by current scientific models. It’s emitting the highest-energy gamma rays ever observed from a pulsar – a highly magnetized and rapidly spinning neutron star – at more than 100 billion electron volts. That’s more than 50 billion times more energy than the visible light from the sun. “This is the highest energy pulsar system ever detected,” said Rene Ong, a UCLA professor of physics and astronomy and … Continue reading

Strange emissions by sun are suddenly mutating matter

The angry sun For months mounting fear has driven researchers to wring their hands over the approaching solar storms. Some have predicted devastating solar tsunamis that could wipe away our advanced technology, others voiced dire warnings that violent explosions on the surface of the sun could reach out to Earth, breach our magnetic field, and expose billions to high intensity X-rays and other deadly forms of cancer-causing radiation. Now evidence has surfaced that something potentially more dangerous is happening deep within the hidden core of … Continue reading

New Forecast: Sun’s ‘Superstorms’ Could Doom Satellites

One of the first images taken by SDO and still a favorite: A solar eruptive prominence as seen in extreme UV light on March 30, 2010. The superimposed image of the Earth gives a sense of just how large these eruptions can be.  CREDIT: NASA/SDO Magnetic storms set off by the sun could pose a bigger threat than thought to weather, communication, military and other satellites close to Earth, with a potentially devastating economic impact, scientists suggest. In the new study, researchers found that solar … Continue reading

Solar Megastorm Could Cripple Satellites for a Decade

Satellites not strong enough to withstand sun’s explosions, model shows. Earth-orbiting satellites are designed to withstand the sun’s explosions—but they may not be strong enough to ride out a solar “megastorm,” a new study says. If hit by a powerful onslaught of solar energy and particles, Earth’s atmosphere would be flooded with high-energy electrons accelerated to nearly the speed of light, according to a new computer model. This would hinder operations of low-Earth orbiting, or LEO, satellites. The satellites wouldn’t immediately start falling out of … Continue reading

Solar flare could unleash nuclear holocaust across planet Earth

Forget about the 2012 Mayan calendar, comet Elenin or the Rapture. The real threat to human civilization is far more mundane, and it’s right in front of our noses. If Fukushima has taught us anything, it’s that just one runaway meltdown of fissionable nuclear material can have wide-ranging and potentially devastating consequences for life on Earth. To date, Fukushima has already released168 times the total radiation released from the Hiroshima nuclear bomb detonated in 1945, and the Fukushima catastrophe is now undeniably the worst nuclear … Continue reading
