Volcanic Activity

By The Associated Press

JAKARTA, Indonesia – A volcano in northern Indonesia has spewed hot smoke and ash thousands of feet into the air in two new eruptions.

Mount Lokon on Sulawesi island had been dormant before rumbling back to life last year.

Government volcanologist Hendrasto says it unleashed two strong eruptions Friday.

Residents have been put on alert, but no evacuations are planned since the nearest villages are beyond the danger area about 2.5 kilometres (1.5 miles) from the crater.

Mount Lokon’s last major eruption in 1991 killed a Swiss hiker and forced thousands to flee. The volcano is one of five on high alert in Indonesia. The archipelago straddles the “Pacific Ring of Fire” and has more active volcanoes than any other nation.

Niger floods kill at least 92 people

Niamey, Niger – At least 92 people have died in floods that have swept Niger following torrential rains, according to the latest data released by the Prime minister’s office on Friday. The data indicate that 72,396 families are affected with 511,484 people being victims, as at Thursday. All the country’s eight regions are affected by floods with Tillabéry, Dosso and Niamey being the worst affected. Huge damage is reported on basic socio-economic infrastructure and other items crucial to the people.

Rice crops, schools, health centres, roads, bridges, dams have all been affected while a huge quantities of food and many cattle have been swept away by flood waters.

The chairperson of the technical committee in charge of managing the floods, Mrs Saadatou Malam Barmou, said that thanks to national solidarity and international cooperation, food needs are covered for 45 days out.

Water containers have been distributed to victims to fetch potable water to reduce water-related diseases. The ministry of Health has also set up health centres at the sites and mobile teams to solve health problems.

The government has made available 3,400 tonnes of cereals for the victims and raised 700 million CFAF to support re-housing and buy additional food.

Flooding, landslides plague parts of Alaska

The Associated Press

ANCHORAGE, Alaska — Flooding continues to cause problems throughout Southcentral Alaska.

Jeremy Zidek, spokesman for the state Division of Homeland Security and Emergency Management, says in a release that there have been reports of flooding, landslides and road closures throughout the area.

But there has been no report of major injuries.

Residents in East Talkeetna are being told to evacuate because of flooding.

The Red Cross has established three shelters in the Matanuska-Susitna Borough and helped with another in Seward.

Weather problems are not confined to Southcentral Alaska.

Zidek says a landslide has blocked access from the village of Chenega to its airport, and state transportation officials are working to restore access. And an assessment team is in Tanacross to evaluate damage from Sunday’s wind storm.

22.09.2012 Flood Cameroon Multiple areas, [Far North, Nort Regions] Damage level Details

Flood in Cameroon on Saturday, 22 September, 2012 at 13:44 (01:44 PM) UTC.

Description
Cameroon authorities have found six more bodies in flood waters, bringing the number killed to as high as 40 in the wake of tropical downpours and the breaching of a dam in the west African country. The inundation in the Far North Region has affected more than 26,000, officials said Thursday, and in neighboring Nigeria at least 15 deaths are blamed on waters rushing into the country from Cameroon’s compromised Lagdo Dam on the Benoue River. Cameroon’s Communication Minister Issa Tchiroma Bakary has described the flooding as “a calamity” and called for urgent action to save lives and property. Local officials are calling it the worst flood disaster in over 60 years. Water has submerged swaths of the North Region downstream, wiping out homes, farms and livestock, and Cameroon’s government has dispatched a military contingency to assist and evacuate victims.

Back

Updated: Saturday, 22 September, 2012 at 04:46 UTC
Description
Residents of Talkeetna are being asked to evacuate the town after its dike system against heavy flooding failed Friday, according to local firefighters. The evacuation is now voluntary, although an initial order was mandatory. Talkeetna Fire Department Battalion Chief Johnny Murdoch, the incident commander for flooding in the area, says the Susitna River started backing up to the Talkeetna River, causing the dike to fail. According to local officials the decision to evacuate Talkeetna was made by Alaska State Troopers, with authorities expecting water to continue rising Friday afternoon. The Associated Press reports that overnight rains in Talkeetna ranged from half an inch to 1 1/2 inches over a 6- to 8-hour period. The Talkeetna River was within a foot of its record stage of 17.4 feet, with officials telling the AP about 35 percent of Talkeetna has some form of water coverage. Students from Talkeetna’s elementary school were being bused to the local high school Friday. Traffic was blocked from entering Talkeetna until the evacuation was no longer mandatory, a change made shortly before 2 p.m. In a flood warning effective through 10 p.m. Friday, the National Weather Service says a levee protecting the town was breached as of 1 p.m. The Talkeetna River is 4 feet above flood stage, and expected to crest Friday evening. “All persons in the vicinity of Talkeetna should take precautions now to protect life and property,” meteorologists wrote. The NWS advises people to avoid crossing flowing streams — even small ones – on foot, or driving across flooded roadways in cars, under the slogan “Turn around, don’t drown.”

The tsunami in Japan in March 2011 unleashed a series of negligence related with the resulting nuclear disaster. A scientific study headed by Spanish researchers has for the first time identified those atomic power plants that are more prone to suffering the effects of a tsunami. In total, 23 plants are in dangerous areas, including Fukushima I, with 74 reactors located in the east and southeast of Asia.

Tsunamis are synonymous with the destruction of cities and homes and since the Japanese coast was devastated in March 2011 we now know that they cause nuclear disaster, endanger the safety of the population and pollute the environment. As such phenomena are still difficult to predict, a team of scientists have assessed “potentially dangerous” areas that are home to completed nuclear plants or those under construction. In the study published in the ‘Natural Hazards’ journal, the researchers drew a map of the world’s geographic zones that are more at risk of large tsunamis. Based on this data, 23 nuclear power plants with 74 reactors have been identified in high risk areas. One of them includes Fukushima I. Out of them, 13 plants with 29 reactors are active; another four, that now have 20 reactors, are being expanded to house nine more; and there are seven new plants under construction with 16 reactors. “We are dealing with the first vision of the global distribution of civil nuclear power plants situated on the coast and exposed to tsunamis,” as explained to SINC by José Manuel Rodríguez-Llanes, coauthor of the study and researcher at the Centre for Research on the Epidemiology of Disasters (CRED) of the Catholic University of Leuven in Belgium. The authors used historical, archaeological, geological and instrumental records as a base for determining tsunami risk. Despite the fact that the risk of these natural disasters threatens practically the entire western coast of the American continent, the Spanish/Portuguese Atlantic Coast and the coast of North Africa, the Eastern Mediterranean and areas of Oceania, especially in South and Southeast Asia are at greater risk due to the presence of atomic power stations.

23 nuclear power plants are in tsunami risk areas Credit: SINC For Debarati Guha-Sapir, another coauthor of the study and CRED researcher, “the impact of natural disaster is getting worse due to the growing interaction with technological installations.” China: a nuclear power in the making Some 27 out of 64 nuclear reactors that are currently under construction in the world are found in China. This is an example of the massive nuclear investment of the Asian giant. “The most important fact is that 19 (two of which are in Taiwan) out of the 27 reactors are being built in areas identified as dangerous,” state the authors of the study. In the case of Japan, which in March 2011 suffered the consequences of the worse tsunami in its history, there are seven plants with 19 reactors at risk, one of which is currently under construction. South Korea is now expanding two plants at risk with five reactors. India (two reactors) and Pakistan (one reactor) could also feel the consequences of a tsunami in the plants. The ghost of Fukushima “The location of nuclear installations does not only have implications for their host countries but also for the areas which could be affected by radioactive leaks,” as outlined to SINC by Joaquín Rodríguez-Vidal, lead author of the study and researcher at the Geodynamics and Paleontology Department of the University of Huelva. According to the study, we should learn our lessons from the Fukushima accident. For the authors, prevention and previous scientific studies are the best tools for avoiding such disasters. “But since the tsunami in 2004 the Indian Ocean region is still to take effective political measures,” warn the researchers. The Fukushima crisis took place in a highly developed country with one of the highest standards in scientific knowledge and technological infrastructure. “If it had occurred in a country less equipped for dealing with the consequences of catastrophe, the impact would have been a lot more serious for the world at large,” claim the experts. Therefore, Professor Rodríguez-Vidal recommends the drafting of more local analyses that consider the seismic amplification of each nuclear power plant and determine the adaptation of installation identified in the study.

Japan Backpedals on “No Nukes” Policy

Published on Sep 19, 2012 by

Last week, Japan surprised the world by announcing that it plans to abandon atomic energy completely by the 2030s. But now in an abrupt turnaround, the Japanese Cabinet appears to be backpedaling on that decision, dropping any mention of the 2030s deadline in its approval of Japan’s new energy policy.

7m and 470kg of steel frame dropped into the SFP of reactor3, “566 fuel assemblies are in the pool”

Posted by Mochizuki on September 22nd, 2012 · No Comments

About 11:05 of 9/22/2012, Tepco dropped a steel frame of 7m long and 470kg into the SFP of reactor3. 514 assemblies of spent fuel and 52 fuel assemblies are kept in the pool.

Tepco was removing debris by the remote controlling crane and dropped it into the pool mistakenly.

The steel frame was 30cm×20cm×7m, 470kg. It was dropped from South-East side.

Tepco states the radiation level did not change, the dosimeter set 2m above the pool did not measure any change in radiation level either. Water level and the temperature did not change.

It hasn’t happened that such a large material dropped into the pool. Tepco is planning to investigate if the fuel assemblies are not damaged by underwater camera.

9/22 午前11:05頃、東電が長さ7m、重さ470kgの鉄骨を3号機使用済み核燃料プールに落としました。
このプールには514体の使用済み核燃料集合体と、52体の新燃料が入っています。

遠隔操作が可能な無人クレーンで瓦礫を撤去していたところ、鉄骨を落としてしまったということです。
落ちた鉄骨は、縦30センチ、横20センチ、長さ7メートルで、重さは470キロあり、プールの南東側から落ちたということです。

東電はこれまでのところ、プールに設置している線量計やプールの水に含まれる放射性物質の濃度、それに水位に変化はなく、冷却も問題なくできている と説明していますが、これほど大きなものがプールに落ちたことはないことから、核燃料集合体が損傷していないか今後水中カメラを使って調べるとしていま す。

Tritium leakage from reactor 5 and 6

Posted by Mochizuki
On 9/21/2012, Tepco released the nuclear analysis result of radioactive materials in the sea water.

The samples were taken on 4/16 and 5/14, so their release is 5 ~ 4 months behind.

The result shows 3.8 ~ 6.0 Bq/L of tritium leakage from around reactor 5 and 6 (North of Unit 5-6 Discharge Channel).

Tepco evaluates it is from the Fukushima accident.  From April to May, the tritium amount increased.

Epidemic Hazards / Diseases

West Nile virus kills 5 in Balkans, dozens in hospital

PRISTINA,   (bdnews24.com/Reuters) – At least five people in the Balkans have died from West Nile virus and several dozen others have been hospitalized in the past four weeks, according to health authorities in Serbia, Kosovo, Macedonia and Croatia.

West Nile virus is a mosquito-borne disease usually found in temperate and tropical regions. While many cases are mild and have no symptoms, severe disease symptoms can include headaches, high fever, neck stiffness, coma, tremors, convulsions, muscle weakness and paralysis.

Kosovo confirmed its first fatality on Wednesday, saying the victim was a woman from central Kosovo who died on Sept 14. Macedonia’s health officials said on Thursday one woman had died and two other people were infected with the virus.

A spokesman for the Kosovo Health Ministry told Reuters on Thursday two other people who died recently were also suspected of having the same virus, but the cases had not been confirmed with laboratory blood tests.

The United States is currently experiencing one of its worst outbreaks of West Nile virus since 2003.

In Serbia, three people have died and 35 were hospitalized since mid-August.

“This is the first time the West Nile virus has been officially registered in Serbia,” the country’s Department for Public Health said in a statement.

All the infected people were over 50 and had other chronic diseases, it said. Serbia’s western neighbor Croatia has registered five probable cases of the virus but no deaths.

Health: Measles epidemic kills 22 in Congo

Measles epidemic Congo – An outbreak of measles, which has been raging in Likouala, North-eastern Congo since April, has already killed 22 people, the state-run radio said Friday.

The epidemic, which initially hit Liranga and Bétou, have now reached Impfondo and Epena.

Following the outbreak, the Ministry of Health Thursday launched a 5-day vaccination campaign against measles in the district.

Vaccination teams will travel throughout the localities of Likouala, which since 2009 has sheltered over 100,000 refugees from the Democratic Republic of Congo (DRC), who are fleeing inter-ethnic violence in the Equateur province.

22.09.2012 Epidemic Hazard USA State of New York, [Ulster County] Damage level Details

Epidemic Hazard in USA on Saturday, 22 September, 2012 at 17:13 (05:13 PM) UTC.

Description
– In light of confirmation of a measles case in a school-aged child in Ulster County, State Health Commissioner Nirav R. Shah, M.D., M.P.H., advises all New Yorkers to be vaccinated against measles. “Many people think measles is a childhood disease of the past, but it remains a highly-contagious viral disease that can cause serious health problems and even death,” Shah said. “The good news is that measles is preventable, and people who are vaccinated can protect themselves against the disease.” The current Ulster County measles case involves a child who attends a school where nearly half of the students are not vaccinated against measles. Although vaccination against measles is one of the required immunizations for school children in New York, exemptions from the requirement may be granted by a school. The Ulster County Health Department is working with the school district to protect other school children from measles. Unvaccinated children who attend the same Ulster County school as the child with measles and unvaccinated school staff are being excluded from the school for 21 days to help prevent them from contracting or spreading the disease. Individuals are not at risk of contracting measles if they are immune. A person is considered immune if they were born before January 1, 1957, have a history of physician-diagnosed measles, a blood test confirming immunity, or have received two doses of the MMR (Measles, Mumps and Rubella) vaccine. Measles is a highly contagious respiratory disease caused by a virus and is spread by direct contact with nasal or throat secretions of infected people. Due to widespread immunization in the United States, the measles virus does not circulate in this country, but is present in some foreign countries, including some in Europe and Asia. It is strongly recommended that anyone traveling to a country where measles is circulating be immunized before their trip; those who are not immunized could potentially contract the disease while abroad and infect other non-immunized individuals upon their return back to the U.S.
Biohazard name: Measles
Biohazard level: 2/4 Medium
Biohazard desc.: Bacteria and viruses that cause only mild disease to humans, or are difficult to contract via aerosol in a lab setting, such as hepatitis A, B, and C, influenza A, Lyme disease, salmonella, mumps, measles, scrapie, dengue fever, and HIV. “Routine diagnostic work with clinical specimens can be done safely at Biosafety Level 2, using Biosafety Level 2 practices and procedures. Research work (including co-cultivation, virus replication studies, or manipulations involving concentrated virus) can be done in a BSL-2 (P2) facility, using BSL-3 practices and procedures. Virus production activities, including virus concentrations, require a BSL-3 (P3) facility and use of BSL-3 practices and procedures”, see Recommended Biosafety Levels for Infectious Agents.

22.09.2012 Epidemic Hazard Sudan South Sudan, [In some refugees camp] Damage level Details

Epidemic Hazard in Sudan on Saturday, 22 September, 2012 at 13:38 (01:38 PM) UTC.

Description
The international humanitarian agency Oxfam is warning that living conditions of refugees in a camp in Upper Nile state are becoming increasingly desperate, and more people will probably die if help does not arrive soon. More than 100,000 refugees have fled fighting between Sudanese armed forces and rebels in Sudan’s Blue Nile and Southern Kordofan states. At least 16 refugees have died in the past two weeks from an outbreak of Hepatitis E, according to the U.N. Pauline Ballaman, Oxfam’s South Sudan director, said the best way to curb the spread of the water-borne disease is to relocate thousands of Sudanese refugees to a safer place. “The government of South Sudan and UNHCR, who are the lead agencies, would encourage them to look at all other possibilities because this is not going to be a sustainable job or solution,” Ballaman said. South Sudan and the UN refugee agency considered relocating the refugees to areas along the Nile River, according to Ballaman, but she said no decision has been made so far. Ballaman said more people are showing symptoms of Hepatitis E. She added, “there are a lot more people affected and, of course, it is far more serious for the nursing and pregnant mothers and young children, and malnutrition kicks in as well,” According to Ballaman, no season is favorable to housing more than 100,000 refugees. Widespread flooding during South Sudan’s rainy season is the problem right now, but when the dry season arrives the problem will be not enough water.

23.09.2012 Epidemic Hazard USA State of New York, New Paltz [Mountain Laurel Waldorf School] Damage level Details

Epidemic Hazard in USA on Saturday, 22 September, 2012 at 05:13 (05:13 AM) UTC.

Description
A case of measles has been confirmed in a student who attends the Mountain Laurel Waldorf School in New Paltz, according to the Dutchess County Department of Health. The measles case was reported by Dutchess County Health Commissioner Dr. Michael Caldwell in a press release emailed to local media outlets late Friday. It was not immediately clear why the release came from a Dutchess County official rather than one in Ulster County, where the private school is located, and the name and hometown of the infected person were not provided. Caldwell said his office has “been in close communication” with the Ulster County Department of Health and the state Department of Health. Caldwell said anyone who has visited the school since Sept. 10 or has had contact with anyone from the school since that date should make sure their measles vaccinations are up to date. Those who lack proper vaccinations should consult with a doctor. Caldwell said his department has learned that a number of students at the New Paltz school have not been vaccinated for measles, meaning they could become ill and put others at risk. Caldwell said all medical practices and laboratories in the area should be on high alert that there may be a number of children and family members who have been exposed and could spread the disease further. Incidents of measles, which is highly contagious, have increased in the United States recently due to a growing number of unvaccinated individuals who travel to countries where measles is prevalent, Caldwell said.

22.09.2012 Event into space Ireland Multiple areas, [Over the Ireland airspace] Damage level Details

Event into space in Ireland on Saturday, 22 September, 2012 at 13:27 (01:27 PM) UTC.

Description
A massive fireball was seen right across Ireland last night which may be “one of the best ever seen” in Europe and was a “huge event”, according to Astronomy Ireland. The trail of fragments passed across the sky at about 10.55pm with sightings reported from Dublin, Donegal, Cork, Sligo, Carlow, Longford, Antrim and across Britain and as far away as as The Netherlands. It was “very unusual to see it in multiple countries,” David Moore of Astronomy Ireland said. “I’ve never seen one fragmented like that and streaked across the sky,” he said. The fireball later exploded into fragments. Mr Moore said the cause of the fireball was not yet clear. “It is a piece of space debris, but whether it is man made or natural is not known,” he said. He said it was too slow for natural debris and was going the wrong direction for man-made debris. “It is probably a space rock that has skidded across the atmosphere.” Meteorites will have been dropped “but whether they landed in Ireland or at sea we will have to figure out”, he said. Witnesses described a trail of seven to 12 fireballs in a straight line across the sky. No sound was to be heard either by witnesses in the city or the countryside. Kielder Observatory in Britain last night reported a sighting of a “huge fireball” .Mr Moore asked for witnesses to submit a fireball report to the Astronomy Ireland website “This will help us to triangulate the path,” he said. Twitter and Facebook filled with reports of the strange sightings last night, with meteor trending on Twitter in Ireland. “Spotted what looked like about eight fireballs travelling east to west over the M1 at Santry, Dublin at 10.56pm. Amazing,” wrote one tweeter last night. The Irish Coast Guard had reports from the north coast right down the east coast.
22.09.2012 Event into space United Kingdom Scotland and England, [Between Airdrie and Arbroath, Greater Manchester] Damage level Details

Event into space in United Kingdom on Saturday, 22 September, 2012 at 04:54 (04:54 AM) UTC.

Description
A suspected meteorite shower over Scotland has prompted a flurry of 999 calls from worried members of the public. Concerned callers from Airdrie to Arbroath likened the lights they saw in the sky to flares, fireworks and even a plane crash. Coastguard and police forces up and down the country were inundated with reports from around 11pm on Friday night. A spokesman for Forth Coastguard said: “From talking to other stations and to the RAF it’s almost certainly meteorite activity. “Calls came in from all over the place, thick and fast. We’ve had people report possible plane crashes, and others the weirdest fireworks they’ve ever seen. “Folk just haven’t known how to describe what they’ve seen. It’s quite extraordinary.” The spokesman said reports had come from Crail, Johnshaven and Arbroath. Clyde Coastguard said it had received a “flurry” of calls reporting flares seen in Drummore, Airdrie and Brodick on Arran. A spokeswoman said: “When we get it all over and at the same time then we attribute them to meteorites. There was meteorite activity forecast from September 15 to 21.” Shetland Coastguard said a report of a flare at 11.10pm at Duncansby Head near John O’Groats was thought to be part of the meteorite shower.

Beautiful and Mysterious Superbubble In The Large Magellanic Cloud
Observed By Chandra
 

MessageToEagle.com – Beautiful and mysterious structures known as superbubbles result from the stellar winds and supernovae of OB [spectral types O or early-type B] associations.

Astronomers believe they play play a fundamental role in the structure and energetics of the ISM [interstellar medium] in star-forming galaxies.

Their influence may also dominate the relationship between the different interstellar gas phases.

How do superbubbles form and evolve?
How do they affect the local and global ISM?

The Magellanic Clouds provide a superior opportunity to study this shell-forming activity, since both stellar content and gaseous structure can be examined in detail.

A superbubble in the Large Magellanic Cloud (LMC) was observed by astronomers using Chandra X-ray Observatory.

LMC is a small satellite galaxy of the Milky Way, located about 160,000 light years from Earth.

Many new stars, some of them very massive, are forming in the star cluster NGC 1929, which is embedded in the nebula N44.

The massive stars produce intense radiation, expel matter at high speeds, and race through their evolution to explode as supernovas.

The winds and supernova shock waves carve out huge cavities called superbubbles in the surrounding gas. X-rays from NASA’s Chandra X-ray Observatory (blue) show hot regions created by these winds and shocks, while infrared data from NASA’s Spitzer Space Telescope (red) outline where the dust and cooler gas are found.

The optical light from the 2.2m Max-Planck-ESO telescope (yellow) in Chile shows where ultraviolet radiation from hot, young stars is causing gas in the nebula to glow.

A long-running problem in high-energy astrophysics has been that some superbubbles in the LMC, including N44, give off a lot more X-rays than expected from models of their structure.


A Chandra study published in 2011 showed that there are two extra sources of the bright X-ray emission: supernova shock waves striking the walls of the cavities, and hot material evaporating from the cavity walls.

The observations show no evidence for an enhancement of elements heavier than hydrogen and helium in the cavities, thus ruling out this possibility as an explanation for the bright X-ray emission.

This is the first time that the data have been good enough to distinguish between different sources of the X-rays produced by superbubbles.

The Chandra study of N44 and another superbubble in the LMC was led by Anne Jaskot from the University of Michigan in Ann Arbor. The co-authors were Dave Strickland from Johns Hopkins University in Baltimore, MD, Sally Oey from University of Michigan, You-Hua Chu from University of Illinois and Guillermo Garcia-Segura from Instituto de Astronomia-UNAM in Ensenada, Mexico.

New Photos Of Saturn And Its Moon Titan –
See A Striking Change Of Colors!
 

MessageToEagle.com – Cassini spacecraft has taken great photos of Saturn and its largest moon, Titan.

The colors are spectacular and on one of the images you can even see the changing hues of Saturn’s northern and southern hemispheres as they pass from one season to the next.

Upon Cassini’s arrival at Saturn eight years ago, Saturn’s northern winter hemisphere was an azure blue.

Now that winter is encroaching on the planet’s southern hemisphere and summer on the north, the color scheme is reversing: blue is tinting the southern atmosphere and is fading from the north.

Some of these views, such as those of the polar vortex, are only possible because Cassini’s newly inclined — or tilted — orbits allow more direct viewing of the polar regions of Saturn and its moons.

A giant of a moon appears before a giant of a planet undergoing seasonal changes in this natural color view of Titan and Saturn from NASA’s Cassini spacecraft.

Titan, Saturn’s largest moon, measures 3,200 miles, or 5,150 kilometers, across and is larger than the planet Mercury. Cassini scientists have been watching the moon’s south pole since a vortex appeared in its atmosphere in 2012.

As the seasons have changed in the Saturnian system, and spring has come to the north and autumn to the south, the azure blue in the northern Saturnian hemisphere that greeted Cassini upon its arrival in 2004 is now fading. The southern hemisphere, in its approach to winter, is taking on a bluish hue. This change is likely due to the reduced intensity of ultraviolet light and the haze it produces in the hemisphere approaching winter, and the increasing intensity of ultraviolet light and haze production in the hemisphere approaching summer.

Scientists are looking forward to seeing more of the same — new phenomena like Titan’s south polar vortex and changes wrought by the passage of time and seasons — during the remainder of Cassini’s mission.

“Cassini has been in orbit now for the last eight years, and despite the fact that we can’t know exactly what the next five years will show us, we can be certain that whatever it is will be wondrous,” said Carolyn Porco, imaging team lead based at the Space Science Institute in Boulder, Colo.“It is so fantastic to experience, through the instruments of Cassini, seasonal changes in the Saturn system,” said Amanda Hendrix, deputy project scientist, based at NASA’s Jet Propulsion Laboratory in Pasadena, Calif.

“Some of the changes we see in the data are completely unexpected, while some occur like clockwork on a seasonal timescale.

It’s an exciting time to be at Saturn.”
