Engineers and scientists at the Lockheed Martin [NYSE: LMT] Space Systems Advanced Technology Center (ATC) have completed delivery of key hardware subsystems for NASA´s Magnetosphereic Multiscale mission (MMS). The delivery comprised four flight subsystems and one flight spare unit. The prime contractor Southwest Research Institute (SWRI) partnered with Lockheed Martin to develop and build the Hot Plasma Composition Analyzer (HPCA) as part of the MMS instrument suite. When it launches...

When the sun launched a moderate, or M-class, solar flare May 17, 2012, it was still one of the largest eruptions seen since late January when our star began to rouse from an anomalously long quiet period. But the event was not just an additional solar wake-up call; it produced something that has the solar physics community puzzled and scientists from the University of New Hampshire poised to analyze a singular dataset gathered during the event by a European satellite called PAMELA - short...

Astronomers Capture Images of Massive Solar Tornado

A NASA satellite has captured images of a solar tornado that is said to be five times as wide as Earth and one of the largest such structures ever discovered on our sun, astronomers revealed during the National Astronomy Meeting in Manchester, England, on Friday. According to CNET Senior Writer Martin LaMonica, a video of the solar twister, which was recorded last September by a telescope equipped to the US space agency's Solar Dynamic Observatory (SDO) satellite, was presented during the...

Massive solar flares could bring down the national electrical grid and affect power in the U.S. “for a period of years,” according to a 2009 NASA report. On March 27th Jack Jobe, Emmy-nominated journalist and survival teacher, shows how to prepare yourself and your family on National Geographic´s “Doomsday Preppers.” Aurora, Colorado (PRWEB) March 24, 2012 National Geographic takes viewers inside the world of Jack Jobe, a “Common Sense Survival...

Solar Storm Threat Appears To Have Passed

[ Watch the Solar Flare in Action Here and Here ] Two recent Coronal Mass Ejections (CMEs) -- massive bursts of solar wind produced by the Sun -- appear to have caused little or no damage to electrical systems, according to scientists. The CMEs were caught by NASA as they took off from the Sun, traveling faster than 1,300 miles per second. The first wave hit yesterday morning, March 8. The second hit late last night into early this morning. Joseph Kunches, a scientist with the...

CMEs Heading Towards Earth

[ Watch the Solar Flare in Action Here and Here ] NASA said on Wednesday that two Coronal Mass Ejections (CMEs) are now traveling faster than 1,300 miles per second, on track towards Earth. NASA's Solar Terrestrial Relations Observatory (STEREO) and the Solar Heliospheric Observatory (SOHO) caught the CMEs as they took-off from the sun. The space agency said the first CME, which is traveling at about 1,300 miles per second, will reach Earth on the morning of March 8. This CME...

Flying Through A Geomagnetic Storm

[ Watch the Video ] Glowing green and red, shimmering hypnotically across the night sky, the aurora borealis is a wonder to behold.  Longtime sky watchers say it is the greatest show on Earth. It might be the greatest show in Earth orbit, too. High above our planet, astronauts onboard the International Space Station (ISS) have been enjoying an up-close view of auroras outside their windows as the ISS flies through geomagnetic storms. “We can actually fly into the...

RHESSI Mission Celebrates Ten Years And Forty Thousand X-Ray Flares

[ Watch the Video ] On February 5, 2002, NASA launched what was then called the High Energy Solar Spectroscopic Imager (HESSI) into orbit. Renamed within months as the Ramaty High Energy Solar Spectroscopic Imager (RHESSI) after Reuven Ramaty, a deceased NASA scientist who had long championed the mission, the spacecraft's job was to observe giant explosions on the sun called solar flares. During a solar flare, the gas soars to over 20 million degrees Fahrenheit, and emits X-rays that...

Sun Delivered Curveball Of Powerful Radiation At Earth
2012-02-02 04:32:26

A potent follow-up solar flare, which occurred Friday (Jan. 27, 2012), just days after the Sun launched the biggest coronal mass ejection (CME) seen in nearly a decade, delivered a powerful radiation punch to Earth's magnetic field despite the fact that it was aimed away from our planet. According to University of New Hampshire scientists currently studying and modeling various aspects of solar radiation, this was due to both the existing population of energetic particles launched by the...


Word of the Day
barghest
  • A goblin in English folklore, often appearing in the shape of a large dog and believed to portend imminent death or misfortune.
  • A ghost, wraith, hobgoblin, elf, or spirit.
