Sizing Up The Sun

SDO Mission scientists participated in a briefing to discuss the upcoming launch and science of an unprecedented mission to study the sun and its dynamic behaviour. The briefing on the Solar Dynamics Observatory mission took place in Washington and the Kennedy Space Centre in Florida.

A ULA Atlas 5 rocket in a 401 vehicle configuration is scheduled to launch the Solar Dynamics Observatory from the Cape Canaveral Air Force Station, Florida on the 9th February, 2010.
The 1 hour launch window starts at 15:50 GMT.

The launch of NASA's Solar Dynamics Observatory from Cape Canaveral Air Force Station has slipped from Feb. 3 to Feb. 9.
NASA officials said high winds before the holidays delayed the mating of a Centaur upper stage to the United Launch Alliance Atlas V booster, eating up contingency time.

In February, the Solar Dynamic Observatory will launch to study the sun. Every 11 years, the sun undergoes a furious upheaval. Dark sunspots burst forth from beneath the sun's surface. Explosions as powerful as a billion atomic bombs spark intense flares of high-energy radiation. Clouds of gas big enough to swallow planets break away and billow into space. It's a flamboyant display of stellar power.

NASA's Solar Dynamics Observatory Investigates the Sun's Cycle of Highs and Lows
How intense will the next solar cycle be? Can we predict when a violent solar storm will blast Earth with energetic particles? Could a prolonged period of inactivity on the sun plunge Earth into a prolonged winter? These are a few of the questions that scientists anticipate the new Solar Dynamics Observatory (SDO) will help to answer.
Scheduled to launch this winter on an Atlas V rocket, SDO will peer into the sun's atmosphere and probe the sun's inner workings. SDO is the first mission of NASA's Living With a Star program, which seeks to reveal how solar activity is generated and to understand the causes of solar variability and its impact on Earth.

EVE: Measuring the Sun's Hidden Variability
Every 11 years, the sun undergoes a furious upheaval. Dark sunspots burst forth from beneath the sun's surface. Explosions as powerful as a billion atomic bombs spark intense flares of high-energy radiation. Clouds of gas big enough to swallow planets break away and billow into space. It's a flamboyant display of stellar power.
So why can't we see any of it?
Almost none of the drama of Solar Maximum is visible to the human eye. Look at the sun in the noontime sky and - ho-hum - it's the same old bland ball of light.
