Hammond Power Solutions Declares Quarterly DividendThe collaboration between the European Space Agency (ESA) and European Union (EU) continues to gain ground, with the EU committing approximately €9 billion for space activities between 2021 and 2027. This substantial investment supports next-generation space systems and programs designed to protect citizens through advanced Earth observation capabilities. At the forefront of these initiatives is the Copernicus system, which provides free, near real-time satellite and ground-based data for users worldwide. The system’s cornerstone is the Sentinel satellite constellation. Each Sentinel satellite is designed for specific Earth observation tasks, from monitoring climate change and deforestation to tracking urbanization and responding to natural disasters. For example, Sentinel-1 monitors land masses, sea ice, and maritime activity while supporting emergency responses. Sentinel-2 assists with land management and humanitarian efforts through high-resolution imagery. Sentinel-3 delivers precise measurements of surface temperatures and ocean and land colors, while Sentinel-4 and Sentinel-5 focus on air quality and atmospheric monitoring. Finally, Sentinel-6 tracks global sea level changes, offering crucial insights for climate change studies. Launched in 2014, Sentinel-1A was the first of its kind, followed by Sentinel-1B in 2016. Together, these satellites have provided immense value, releasing over 95,000 data products monthly. Users worldwide now download more than 2.3 petabytes of data for free, emphasizing the program’s global importance. How the mission works Latest in the series, the Sentinel-1C satellite took off from the European Spaceport in French Guiana on December 5. The satellite reached orbit aboard the Vega-C, a 35-meter European rocket with a launch mass of 210 tons. The vehicle, capable of lifting 2,300 kg to orbit, completed its mission in eight minutes. According to Simonetta Cheli , ESA’s director of earth observation programs, transitioning to the Vega-C rocket was a challenge, as earlier satellites relied on the now-unavailable Soyuz launcher. Equipped with a C-band synthetic aperture radar, Sentinel-1C will deliver high-resolution imagery, ensuring continuity of data as earlier satellites age. “The novelty of the mission is the fact that it has onboard an AIS instrument, which is an automated identification system. This will be a complementary new tool to the satellite and to the radar system to identify marine ships, help and support improving transport, and that was part of the challenge,” stated Cheli in an interview with Interesting Engineering . Two identical satellites comprise the Sentinel-1 mission, operating from opposite sides of the same orbit to establish comprehensive Earth coverage. After losing Sentinel-1B to technical problems in 2022, rendering it incapable of gathering data, the mission is now operating at its full potential as the new Sentinel-1C works in tandem with Sentinel-1A to form the two-satellite constellation. Sentinel-1D satellite is scheduled to replace Sentinel-1A in the coming year. First images from Sentinel-1C Within a week after entering the orbit, Sentinel-1C took its first radar images. As per a media statement released by ESA , the photos show Svalbard in Norway, the Netherlands, and Brussels in Belgium. The first image, taken just over 56 hours after liftoff, shows Svalbard, a remote Norwegian archipelago in the Arctic Ocean. The second image if of the Netherlands, depicting Amsterdam and the Flevoland region. These first images contribute to numerous scientific areas, including monitoring ground deformation caused by earthquakes, volcanoes, and subsidence, as well as mapping natural resources. The mission supports humanitarian operations and global crisis response. The data is freely available through the Copernicus Data Space, providing access to information essential for environmental monitoring and protection. Converting radiation into energy Sentinel satellites provide high-resolution Earth observation data that can aid in solving challenges we face on the planet. For example, it is possible to get data on pollutants, which can guide the development of nanomaterials for pollution remediation and their effectiveness. Nanomaterials are made up of minute particles that can absorb radiation energy and convert it into light. Nanostructures, on the other hand, are specific arrangements of nanomaterials that can improve their functionality. Testing these materials directly in space opens up several possibilities. This would entail deploying Sentinel data for the development of nanomaterials, which would in turn augment nanotechnology . Additionally, satellite data can help map natural resources, especially mineral resources. According to Professor Liberato Manna from the Italian Institute of Technology, the identification of mineral deposits could be important for the development of new technologies, since critical materials are always needed. Professor Manna is part of a project with the Italian Space Agency which is analyzing materials that can be used as scintillator detectors. A scintillator is a material that absorbs high-energy radiation, such as X-rays and gamma rays, and converts it into light. They are used for example in medical equipment for X-ray imaging, Tomography, and PET. In Manna’s opinion, the same principle could be applied to convert high-energy radiation into electricity, providing satellites with an additional power source. It is akin to your phone having a special coating that converts the sun’s heat into energy, thereby doing away with the need for a charger. Similarly, scintillator nanocrystals can detect high-energy radiation such as gamma rays, and convert them into light or even electricity. So, for example, harmful cosmic radiation that could otherwise damage satellites is absorbed, while part of the radiation could be converted into electricity to power the instruments on the satellite. “In essence, one can make the whole cover of the satellite a gigantic scintillator detector which acts as a radiation shield and a source of electricity at the same time,” observed Manna. Of course, this concept needs further testing. Future space missions will serve as valuable testing grounds, as nanomaterials could enable the creation of highly versatile scintillator detectors. Manna highlighted the importance of understanding the growth of nanomaterials in microgravity, as these environments can result in growth regimes that are highly out of equilibrium, promoting the creation of unique nanostructures. All this indicates that the data we get free of charge from satellites can not only help us combat global problems but can also determine technological development. From ocean to urbanization Furthermore, two recent studies have underscored the importance of satellites in environmental and sociological investigations. Using data from the ESA’s Sentinel-2 satellite, researchers were , for the first time, able to distinguish floating macroplastics mixed with algae and sea foam in coastal waters. Scientists used satellite data to improve the detection of plastic waste in Brazil’s coastal waters. Images beamed from the orbit were studied to classify materials like macroplastics, seaweed, and sea foam in the waters. The model achieved 87.25% accuracy in distinguishing macroplastics from other materials. Meanwhile, another study by researchers from Switzerland, examined high-resolution population maps acquired by Sentinel-1 and Sentinel-2 to develop a population mapping method called ‘Popcorn’. Through this, researchers were able to produce population maps for places in Rwanda which had less than 400 regional census counts. The study claimed the “proposed model has been shown to work well in a range of geographic regions, and greatly simplifies fine-grained population mapping.” The significance of Sentinel satellites cannot be overstated. While they have already proven vital in numerous fields of science, Cheli opines that research in the future should go in the direction of filling existing gaps.mnl168+log+in



BOSTON — Boston City Councilor Tania Fernandes Anderson is the subject of a federal investigation, and subpoenas have been issued to City Hall in relation to the probe, the Herald has learned. The nature and circumstances of the investigation into the second-term city councilor have not been revealed, and no criminal charges have been filed. The city acknowledged the existence of a federal subpoena or subpoenas that have been “issued to the Boston City Council or specific city councilors” in a Friday response to a Herald public records request that sought “information and/or documents relating to federal subpoenas that have been issued to Boston City Hall, the Boston City Council, Boston City Councilor Tania Fernandes Anderson and any of the 13 city councilors from Jan. 1, 2024 to Nov. 14, 2024. The city declined to provide the subpoena or subpoenas, which the Herald has learned pertained to a probe involving Fernandes Anderson, saying that it reached out to the Massachusetts U.S. Attorney’s office to confirm that the “investigatory exemption” of the public records law applied in this instance. According to the U.S. Attorney’s office, release of such information could impair the “integrity of a grand jury investigation,” per the city’s records response. When reached for comment, a spokesperson for the U.S. Attorney’s office declined to comment, saying that the office “can’t confirm or deny an investigation.” Fernandes Anderson, who represents District 7 which includes Roxbury, Dorchester, the South End and Fenway, did not immediately respond to the Herald’s request for comment. She declined to comment when reached by the Boston Globe on Tuesday, per a report from the outlet. “I don’t want to comment on it,” Fernandes Anderson, the first African immigrant and Muslim American elected to the City Council, told the Globe. City Council President Ruthzee Louijeune said in a statement to the Herald that “it is important to respect the legal process.” “Drawing any conclusions right now would be premature,” Louijeune said. “As the president of the Boston City Council and as a lawyer, I want to emphasize that any actions that are found to undermine the law must be taken very seriously. “The work of the Council will proceed without disruption and we will remain focused on the issues most important to residents, including acting with integrity as a body,” Louijeune added. “At this time, I will refrain from any further comments, while urging everyone to avoid speculation and to respect due process.” The existence of a federal probe is the latest controversy for a city councilor who has had her fair share since taking office roughly three years ago. Last month, Fernandes Anderson was hit with a number of state campaign finance violations, per a Nov. 14 letter from the Office of Campaign and Political Finance. The violations included her failure to report roughly $32,900 of $34,500 of campaign contributions over an 11-month period in a timely fashion, and receipt of individual contributions in excess of the $1,000 state limit. The letter notes that the Anderson Committee took steps to resolve the excess contributions, by purging $1,750 to the Commonwealth on Sept. 26 to resolve the individual matter, and refunding $100 to the committee of a state senator that had sent a second $100 contribution in the same calendar year to Fernandes Anderson. Only one $100 contribution per year between two campaign committees is allowed by state law. Fernandes Anderson admitted to a state ethics violation last year for hiring her sister and son to paid positions on her City Council staff and paid a $5,000 fine. The State Ethics Commission said Fernandes Anderson appointed her sister and son to full-time positions in 2022, her first year on the Council. She also chose to increase their salaries, and in the case of her sister, award a $7,000 bonus. Fernandes Anderson set her sister’s salary at $65,000. She awarded her sister a raise in June 2022, increasing her salary to $70,000 and tacking on a $7,000 bonus, the Ethics Commission said. In June 2022, Fernandes Anderson appointed her son as her full-time office manager at an annual salary of $52,000. She participated in the Council’s July 15 vote to approve the appointment. Eleven days later, the councilor increased her son’s salary to $70,000, the Commission said. Fernandes Anderson addressed the matter in several tweets in July 2023 upon the ethics violation becoming public saying that she “messed up” and referencing her sister, said, “You are my everything and if it wasn’t unethical, I’d do it again.” More recently, a video of Fernandes Anderson not saying the oath of office during this past January’s inauguration, in violation of the city charter, went viral on social media. Fernandes Anderson retook the oath privately with the city clerk days later. In a social media statement at the time, she said she had been “internalizing” her oath and “committing a prayer between myself and God.” The 13 city councilors now make a $115,000 salary, after starting the year with an $11,500 pay hike. The last city councilor to be subject to a federal probe while in office was the late Chuck Turner who was sentenced to three years in jail in 2018 for pocketing a $1,000 bribe from an informant who claimed to be seeking a liquor license. Turner sued the city for $350,000 after being booted off the City Council in 2010 following the conviction, and settled for $106,000 eight years later, after the courts ruled that the Council violated its own rules because under state law, elected officials can only be removed from the body after sentencing, not conviction. --------- ©2024 MediaNews Group, Inc.

LONDON — What does a spy agency give for Christmas? How about a riddle wrapped in an enigma inside a mystery. GCHQ, Britain’s electronic and cyber-intelligence agency, on Wednesday published its annual Christmas Challenge — a seasonal greeting card that doubles as a set of fiendishly difficult puzzles designed to excite young minds about solving cyphers and unearthing clues. The challenge is aimed at young people aged 11 to 18, who are encouraged to work in teams and use “lateral thinking, ingenuity and perseverance” to crack the seven brainteasers set by GCHQ’s “in-house puzzlers.” The card is sent by the head of GCHQ — short for Government Communications Headquarters — to other national security chiefs around the world. Puzzles were first included in 2015 and have become an annual tradition. The card can be downloaded from the GCHQ website and has become popular with teachers — the agency says a third of British secondary schools have downloaded it. The agency admits the festive fun has an ulterior motive. GCHQ Director Anne Keast-Butler said she hoped the card would inspire young people to explore STEM subjects — science, technology, engineering and mathematics — “and to consider what a career in cybersecurity and intelligence might have to offer.” It also aims to dispel some myths about intelligence work, fueled by super-agent James Bond and other fictional spies. GCHQ’s “chief puzzler,” Colin, said the challenge is best solved by teamwork, in contrast to the popular image of the lone genius or solo secret agent. “Don’t get me wrong — we have geniuses in the department,” said Colin, who gave only his first name because of the secret nature of his work. “But critically what we have is a large number of people with different skills coming together. “The skills we want are quite diverse. We like analytical skills but also lateral thinking skills. And we like the idea with some of these puzzles that it involves a certain amount of perseverance to get to the answer.” The card features a map of the U.K., linked to the locations where GCHQ has bases, including its high-tech headquarters in Cheltenham, western England, nicknamed the doughnut because of its shape. Many British people are keen puzzle-solvers, and the link between puzzlers and spycraft is often celebrated — notably in the many books, films and TV shows about Bletchley Park, a complex of buildings and wooden huts northwest of London where, during World War II, hundreds of mathematicians, cryptologists, crossword puzzle experts and computer pioneers worked to crack Nazi Germany’s secret codes. Historians say their work shortened World War II by as much as two years. Colin said that among new recruits to GCHQ, “we now hear more and more that they first heard of GCHQ through puzzling.” “It definitely inspires people.” Technology has advanced immeasurably since the days of Bletchley Park, but — reassuringly — making and solving puzzles is one area that still needs the human touch. “AI doesn’t have a good record either setting or solving puzzles, not of this sort,” Colin said. “It is still the case that people are able to set interesting puzzles in a way that AI isn’t — thank goodness.” — By JILL LAWLESS, Associated Press

I also put a dryer sheet in each of my gym shoes at home. To freshen my clothes quickly, I put them in the dryer with a dryer sheet on the air cycle. I reuse ones from the dryer to dust with. My sisters place dryer sheets under their bedsheets. Others rub a dryer sheet on their sofas! I love and use many of the suggestions you and others have printed in your column. -- Jackie, Colorado Springs, Colorado SEND A GREAT HINT TO: Heloise@Heloise.com SHREDDED PAPER Dear Heloise: You're a big fan of recycling items, so I thought you might be interested in what we do with shredded paper in our office. Three of us have family in other countries, so we often have to mail Christmas gifts. We have a paper shredder, and when it comes time to empty it, we dump the paper into large plastic bags and save it in a closet. We later use that paper when we mail gifts for various occasions such as weddings, birthdays and Christmas. The word got out, and now there are a couple of other offices in our building that come down for some "packing material." -- Anne H., Milford, Delaware MICROWAVE FUDGE Dear Heloise: When I lived at home, my mother insisted on doing the cooking. She said I always made a mess of her kitchen. In college, we had our meals in the dining hall, so I never really learned how to cook. But now I have my own place, and I would like to make a recipe I saw in your column a couple of years ago. I don't know the name of it, but it was a fudge recipe where you could microwave the ingredients. It sounded good and so easy to make. Would you reprint this recipe? I want to take it to a family gathering for Thanksgiving. -- Jeffery M., in Boulder, Colorado Jeffery, the recipe you're thinking of was called "Matthews' Microwave Fudge," and it was indeed very easy to make. Here is the recipe: -- 1 pound of powdered sugar -- 1/2 cup cocoa -- 1/4 teaspoon butter or margarine -- 4 tablespoons milk -- 1 tablespoon vanilla extract -- 1 cup chopped pecan or walnuts Combine all the ingredients except the nuts in a microwave-safe bowl. Microwave on high until all the ingredients in the mixture are melted and smooth. Remove and stir periodically. When the mixture is smooth, remove it from the microwave and stir in the nuts. Spread the fudge into a buttered 9-by-5-inch loaf pan and allow it to cool completely before cutting it into bite-sized pieces. -- Heloise REUSING STOCKINGS Dear Heloise: Last week while I was making soup, I wanted to put certain spices in a square of gauze or cheesecloth and found that I had neither in my house. I looked around and finally found a clean nylon stocking I no longer wore or needed. I placed the spices in a square I had cut from the nylon stocking and tied it at the top! It worked very well! -- Louella T., Livingston, Montana
