Solar Activity Continues On The Sun
2013-05-15 11:28:59

NASA Solar activity continued on May 14, 2013, as the sun emitted a fourth X-class flare from its upper left limb, peaking at 9:48 p.m. EDT. This flare is classified as an X1.2 flare and it is the 18th X-class flare of the current solar cycle. The flare caused a radio blackout — categorized as an R3, or strong, on NOAA´s space weather scales from R1 to R5 -- which has since subsided. The flare was also associated with a non-Earth-directed CME. CMEs and flares are separate but...

The Impacts Of Strong Solar Flares
2013-05-14 07:53:54

NASA Given a legitimate need to protect Earth from the most intense forms of space weather -- great bursts of electromagnetic energy and particles that can sometimes stream from the sun -- some people worry that a gigantic "killer solar flare" could hurl enough energy to destroy Earth, but this is not actually possible. Solar activity is indeed currently ramping up toward what is known as solar maximum, something that occurs approximately every 11 years. However, this same solar cycle...

Mid-Level Solar Flare Emitted By The Sun
2013-05-04 08:29:41

NASA The sun emitted a mid-level solar flare, peaking at 1:32 pm EDT on May 3, 2013. Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth's atmosphere to physically affect humans on the ground, however -- when intense enough -- they can disturb the atmosphere in the layer where GPS and communications signals travel. This disrupts the radio signals for as long as the flare is ongoing, and the radio blackout for this flare has already...

Satellite Instrument Package To Assess Space Weather Ready For Delivery
2013-05-02 15:25:32

University of Colorado Boulder A multimillion dollar University of Colorado Boulder instrument package to study space weather has passed its pre-installation testing and is ready to be incorporated onto a National Oceanic and Atmospheric Administration satellite for a 2015 launch. Designed and built by CU´s Laboratory for Atmospheric and Space Physics, the instrument suite known as the Extreme Ultraviolet and X-ray Irradiance Sensors, or EXIS, is the first of four identical...

Orbital To Build Icon Space Weather Satellite For NASA
2013-04-30 04:53:34

redOrbit Staff & Wire Reports - Your Universe Online NASA has awarded a two-year, $50 million contract to Orbital Sciences Corporation to build a new heliophysics science satellite that will investigate the connection between space weather storms in the ionosphere and Earth´s terrestrial weather. The mission is currently set to launch in 2017, and will study the interface between the upper reaches of the Earth´s atmosphere and outer space in response to a recent scientific...

NASA Mission To Study What Interferes With Radio Waves
2013-04-26 07:44:43

NASA A NASA-funded sounding rocket mission will launch from an atoll in the Pacific in the next few weeks to help scientists better understand and predict the electrical storms in Earth's upper atmosphere. These storms can interfere with satellite communication and global positioning signals. The mission, called EVEX, for the Equatorial Vortex Experiment, will launch two rockets for a twelve-minute journey through the equatorial ionosphere above the South Pacific. The launch window for...

NASA’s Next Space Weather Satellite To Be Built By UC Berkeley
2013-04-17 14:32:11

University of California, Berkeley NASA has awarded the University of California, Berkeley, up to $200 million to build a satellite to determine how Earth´s weather affects weather at the edge of space, in hopes of improving forecasts of extreme “space weather” that can disrupt global positioning satellites (GPS) and radio communications. The satellite mission, called the Ionospheric Connection Explorer (ICON), will be designed, built and operated by scientists at UC...

NASA Wind Discovers SLAMS Magnetic Waves
2013-04-17 11:48:16

redOrbit Staff & Wire Reports - Your Universe Online Analysis of data collected by NASA´s Wind spacecraft as it traveled through the front of the Earth´s magnetosphere from 1998 through 2002 has revealed a special type of magnetic pulsations, scientists from the US space agency revealed on Tuesday. The magnetosphere, a giant area of space created by the Earth´s magnetic fields as it travels around the sun, produces a standing bow wave or bow shock as is travels...

NASA's CINDI Celebrating Fifth Anniversary
2013-04-15 15:10:13

NASA On April 16, 2008, a suite of NASA instruments was launched into space to study a unique region of Earth´s upper atmosphere: the electrically charged region called the ionosphere. The instruments, known collectively as CINDI (Coupled Ion-Neutral Dynamics Investigation), fly aboard an Air Force Research Laboratory satellite called C/NOFS (Communications/Navigation Outage Forecasting System) to study this region that hovers some 60 to 400 miles above Earth. The ionosphere is...


Word of the Day
mallemaroking
  • Nautical, the visiting and carousing of sailors in the Greenland ships.
This word is apparently from a confusion of two similar Dutch words: 'mallemerok,' a foolish woman, and 'mallemok,' a name for some persons among the crew of a whaling vessel.
