Solar Wind Loses Power, Hits 50-year Low

09.23.2008

Sept. 23, 2008: In a briefing today at NASA headquarters, solar physicists announced that the solar wind is losing power.

"The average pressure of the solar wind has dropped more than 20% since the mid-1990s," says Dave McComas of the Southwest Research Institute in San Antonio, Texas. "This is the weakest it's been since we began monitoring solar wind almost 50 years ago."

McComas is principal investigator for the SWOOPS solar wind sensor onboard the Ulysses spacecraft, which measured the decrease. Ulysses, launched in 1990, circles the sun in a unique orbit that carries it over both the sun's poles and equator, giving Ulysses a global view of solar wind activity:

Above: Global measurements of solar wind pressure by Ulysses. Green curves trace the solar wind in 1992-1998, while blue curves denote lower pressure winds in 2004-2008. [Larger image]

Curiously, the speed of the million mph solar wind hasn't decreased much-only 3%. The change in pressure comes mainly from reductions in temperature and density. The solar wind is 13% cooler and 20% less dense.

"What we're seeing is a long term trend, a steady decrease in pressure that began sometime in the mid-1990s," explains Arik Posner, NASA's Ulysses Program Scientist in Washington DC.

How unusual is this event?

"It's hard to say. We've only been monitoring solar wind since the early years of the Space Age-from the early 60s to the present," says Posner. "Over that period of time, it's unique. How the event stands out over centuries or millennia, however, is anybody's guess. We don't have data going back that far."

Flagging solar wind has repercussions across the entire solar system-beginning with the heliosphere.

The heliosphere is a bubble of magnetism springing from the sun and inflated to colossal proportions by the solar wind. Every planet from Mercury to Pluto and beyond is inside it. The heliosphere is our solar system's first line of defense against galactic cosmic rays. High-energy particles from black holes and supernovas try to enter the solar system, but most are deflected by the heliosphere's magnetic fields.

Right: The heliosphere. Click to view a larger image showing the rest of the bubble.

"The solar wind isn't inflating the heliosphere as much as it used to," says McComas. "That means less shielding against cosmic rays."

In addition to weakened solar wind, "Ulysses also finds that the sun's underlying magnetic field has weakened by more than 30% since the mid-1990s," says Posner. "This reduces natural shielding even more."

Unpublished Ulysses cosmic ray data show that, indeed, high energy (GeV) electrons, a minor but telltale component of cosmic rays around Earth, have jumped in number by about 20%.

These extra particles pose no threat to people on Earth's surface. Our thick atmosphere and planetary magnetic field provide additional layers of protection that keep us safe.

But any extra cosmic rays can have consequences. If the trend continues, astronauts on the Moon or en route to Mars would get a higher dose of space radiation. Robotic space probes and satellites in high Earth orbit face an increased risk of instrument malfunctions and reboots due to cosmic ray strikes. Also, there are controversial studies linking cosmic ray fluxes to cloudiness and climate change on Earth. That link may be tested in the years ahead.

Above: The temperature and density of electrons in the solar wind have dropped since the mid-1990s. [Larger image]

Some of most dramatic effects of the phenomenon may be felt by NASA's two Voyager spacecraft. After traveling outward for 30+ years, the two probes are now at the edge of the heliosphere. With the heliosphere shrinking, the Voyagers may soon find themselves on the outside looking in, thrust into interstellar space long before anyone expected. No spacecraft has ever been outside the heliosphere before and no one knows what the Voyagers may find there.

NASA is about to launch a new spacecraft named IBEX (short for Interstellar Boundary Explorer) that can monitor the dimensions of the heliosphere without actually traveling to the edge of the solar system. IBEX may actually be able to "see" the heliosphere shrinking and anticipate the Voyager's exit. Moreover, IBEX will reveal how our solar system's cosmic ray shield reacts to changes in solar wind.

"The potential for discovery," says McComas, "is breathtaking."

NASA To Discuss Conditions On And Surrounding The Sun

WASHINGTON -- NASA will hold a media teleconference Tuesday, Sept. 23, at 12:30 p.m. EDT, to discuss data from the joint NASA and European Space Agency Ulysses mission that reveals the sun's solar wind is at a 50-year low. The sun's current state could result in changing conditions in the solar system.

Ulysses was the first mission to survey the space environment above and below the poles of the sun. The reams of data Ulysses returned have changed forever the way scientists view our star and its effects. The venerable spacecraft has lasted more than 17 years - almost four times its expected mission lifetime.

The panelists are:
-- Ed Smith, NASA Ulysses project scientist and magnetic field instrument investigator, Jet Propulsion Laboratory, Pasadena, Calif.
-- Dave McComas, Ulysses solar wind instrument principal investigator, Southwest Research Institute, San Antonio
-- Karine Issautier, Ulysses radio wave lead investigator, Observatoire de Paris, Meudon, France
-- Nancy Crooker, Research Professor, Boston University, Boston, Mass.

Fyrr sumar var essi tilkynning ar sem sagt er a virkni nstu slsveiflu geti ori minni en undanfari

International Mission Studying Sun to Conclude
June 12, 2008
PASADENA, Calif. - After more than 17 years of pioneering solar science, a joint NASA and European Space Agency mission to study the sun will end on or about July 1.

The Ulysses spacecraft has endured for almost four times its expected lifespan. However, the spacecraft will cease operations because of a decline in power produced by its onboard generators. Ulysses has forever changed the way scientists view the sun and its effect on the surrounding space. Mission results and the science legacy it leaves behind were reviewed today at a media briefing at European Space Agency Headquarters in Paris.

"The main objective of Ulysses was to study, from every angle, the heliosphere, which is the vast bubble in space carved out by the solar wind," said Ed Smith, Ulysses project scientist at NASA's Jet Propulsion Laboratory, Pasadena, Calif. "Over its long life, Ulysses redefined our knowledge of the heliosphere and went on to answer questions about our solar neighborhood we did not know to ask."


Ulysses ends its career after revealing that the magnetic field emanating from the sun's poles is much weaker than previously observed. This could mean the upcoming solar maximum period will be less intense than in recent history.

"Over almost two decades of science observations by Ulysses, we have learned a lot more than we expected about our star and the way it interacts with the space surrounding it," said Richard Marsden, Ulysses project scientist and mission manager for the European Space Agency (ESA). "Solar missions have appeared in recent years, but Ulysses is still unique today. Its special point of view over the sun's poles never has been covered by any other mission."

The spacecraft and its suite of 10 instruments had to be highly sensitive, yet robust enough to withstand some of the most extreme conditions in the solar system, including intense radiation while passing by the giant planet Jupiter's north pole. The encounter occurred while injecting the mission into its orbit over the sun's poles.

"Ulysses has been a challenging mission since launch," said Ed Massey, Ulysses project manager at JPL. "Its success required the cooperation and intellect of engineers and scientists from around the world."

Ulysses was the first mission to survey the environment in space above and below the poles of the sun in the four dimensions of space and time. It showed the sun's magnetic field is carried into the solar system in a more complicated manner than previously believed. Particles expelled by the sun from low latitudes can climb to high latitudes and vice versa, sometimes unexpectedly finding their way out to the planets. Ulysses also studied dust flowing into our solar system from deep space, and showed it was 30 times more abundant than astronomers suspected. In addition, the spacecraft detected helium atoms from deep space and confirmed the universe does not contain enough matter to eventually halt its expansion.

Ulysses collected and transmitted science data to Earth during its 8.6 billion kilometer journey (5.4 billion miles). As the power supply weakened during the years, engineers devised methods to conserve energy. The power has dwindled to the point where thruster fuel soon will freeze in the spacecraft's pipelines.

"When the last bits of data finally arrive, it surely will be tough to say goodbye," said Nigel Angold, ESA's Ulysses mission operations manager. "But any sadness I might feel will pale in comparison to the pride of working on such a magnificent mission. Although operations will be ending, scientific discoveries from Ulysses data will continue for years to come."

Ulysses was launched aboard space shuttle Discovery on Oct. 6, 1990. From Earth orbit, it was propelled toward Jupiter by solid-fuel rocket motors. Ulysses passed Jupiter on Feb. 8, 1992. The giant planet's gravity then bent the spacecraft's flight path downward and away from the ecliptic plane to place the spacecraft in a final orbit around the sun that would take it past our star's north and south poles.

The spacecraft was provided by ESA. NASA provided the launch vehicle and upper stage boosters. The U.S. Department of Energy supplied a radioisotope thermoelectric generator to provide power to the spacecraft. Science instruments were provided by both U.S. and European investigators. The spacecraft is operated from JPL by a joint NASA/ESA team. More information about the joint NASA/ESA Ulysses mission is available at

Carbon Recycling International captures carbon dioxide from industrial emissions and converts carbon dioxide to ultra clean fuel. The sources of emissions are from basic infrastructure industrial processes including aluminum smeltering, ferro silicon manufacturing, cement production and coal fired power generation.

The fuel is high octane gasoline, ultra low sulfur diesel and methanol for existing automobiles and future hybrid flexible automobiles. The recycling of carbon dioxide results in a net reduction of carbon dioxide and the cost effective conversion enables a sustainable production of synthetic fuel.

The technology is available today and is a viable solution for transport fuel in lieu of hydrogen fuel and carbon sequestration and in complement with oil based fuel.

Founded in 2006, Carbon Recycling International, Ehf, captures carbon recycling from industrial emissions and convert carbon dioxide to methanol, gasoline and diesel. It is a venture backed Icelandic American company with headquarter in Iceland and operation in the US.

Last week this new, shorter Northwest Passage's navigability was dramatically demonstrated as Hudson Bay Company's Eastern Arctic Patrol Nascopie sounded her way through Bellot Strait. Snow shrouded the Arctic dusk as head on through the haze came the bow of another ship. Nascopie's Captain Thomas Smellie's incredulous hail got a booming reply from veteran Arctic Trader Patsy Klingenberg, from the deck of the Schooner Aklavik, eastbound to Baffin Island, and astonished Eskimo cheers from both crews echoed through the rock-bound channel. That night captains of both vessels described from their anchorages to Canadian Broadcasting Co. and NBC audiences their historic meeting. Hopeful for the growing trade of the North were residents and sponsors of Churchill that somehow Northwest Passage II would bring business, help redeem millions of dollars sunk in Canada's most northerly port.

Frbr fyrirlestur undrabarns um fjru vddina, strengjafri og tilraunirnar hj CERN ... Myndband

brian_greene.jpgLangar ig a vita hvers vegna menn leggja svona grarlega miki sig vi reindarannsknir og eru tilbnir a verja 500 milljrum krna vlbna sem 5000 vsindamenn munu koma a? a hltur a vera eitthva strmerkilegt a gerst.

Er etta eitthva sem er ofar skilningi okkar sem ekki eru reindafringar? Er etta eitthva sem hltur a vera mgulegt a skilja? Nei, ekki aldeilis.

Brian Greene er prfessor elisfri og strfri vi Columbia hsklann Bandarkjunum. Hann er einnig frbr fyrirlesari og auvelt me a segja fr annig a allir skilji. Jafnvel g og . Hann er einn ekktasti reindafringur samtmans, en hann er srfingur svokallari strengjafri. Undrabarn sem fr 12 ra gamalt Columbia hsklann til a nema strfri.

fyrirlestrinum myndbandinu lsir hann auskilinn htt eim rsma undraheimi sem vsindamenn um allan heim eru a reyna a skyggnast inn me hjlp reindahraalsins CERN. Eftir aeins feinar mntur erum vi mikils vsari um ennan heim ar sem vddirnar eru ekki aeins rjr, og jafnvel ekki fjrar, heldur tu!

Betri fyrirlesari en Brian Greene er er lklega vandfundinn. Hann er ekktur fyrir a fra almenning um frilega elisfri, m.a. sjnvarpsttum.

a vri frbrt ef sjnvarpi tki til sninga eitthva af ttum hans.

r Wikipedia:

Brian Greene (fddur 3. febrar 1963) er elisfringur og einn ekktasti strengjafringur heims. Hann hefur veri prfessor vi Columbia-hskla san ri 1996. Greene, sem fddur er New York var undrabarn strfri. Hfileikar hans voru slkir, a 12 ra gamall hlaut hann einkakennslu hj strfriprfessor vi Columbia-hskla ar sem hann hafi egar fari langt fram r allri framhaldssklastrfri. ri 1980 innritaist Greene Harvard-hskla til a leggja stund elisfri og sar nam hann vi hsklann Oxford Englandi.

Bk hans The Elegant Universe: Superstrings, Hidden Dimensions, and the Quest for the Ultimate Theory var til ess fallinn a vekja huga strengjakenningunni og M-kenningunni. Hn var tnefnd til Pulitzer verlauna flokki bka sem ekki teljast til skldsagna. Bkin var sar vifangsefni sjnvarpstta PBS sjnvarpstinni ar sem Greene var sgumaur. Seinni bk hans The Fabric of the Cosmos fjallar um tmarm og eli alheimsins.

Brian Greene hefur einnig komi a leiklist, t.a.m. var hann leikaranum John Lithgow til astoar vsindalegan texta sjnvarpsttarinni 3rd Rock from the Sun og kom einnig fram sem aukaleikari myndinni Frequency. Nveri var hann einnig til rgjafar vi kvikmyndina Deja Vu sem fjallar um tmaflakk og inniheldur hugtk r frilegri elisfri.
