A new generation of SpaceX’s Starlink satellites is reportedly disrupting radio astronomy, hindering scientists’ ability to observe the universe, according to researchers at the Netherlands Institute for Radio Astronomy (ASTRON). The interference from these satellites is proving to be a significant obstacle for astronomers, who are raising concerns about the impact on their research.

The issue stems from the second generation of Starlink satellites, which are emitting radio waves that are overpowering and obscuring the signals from distant celestial objects. According to ASTRON, the interference from these newer satellites is 32 times stronger than that from the first-generation models. This radiation exceeds the limits set by the International Telecommunications Union, the industry body responsible for regulating satellite emissions.

Professor Jessica Dempsey, director of ASTRON, highlighted the severity of the issue. “Every time more of these satellites are launched, we see less and less of the sky,” she told BBC News. Dempsey explained that the interference affects critical areas of research, including the study of black hole jets, early galaxies, and exoplanets. The increased brightness of the Starlink satellites is akin to comparing the faintest visible stars to the brightness of the full Moon, according to Cees Bassa, lead author of the study.

The study, conducted using the LOFAR radio telescope, found that almost all observed V2 Starlink satellites emitted unintended electromagnetic radiation, which was about 10 million times brighter than the weakest known sources of light. This level of interference is alarming as it threatens the integrity of ground-based astronomical observations across various wavelengths.

SpaceX, which operates Starlink, has not yet responded to requests for comment from BBC News. However, the company has previously engaged with astronomers about the interference from its first-generation satellites, though the newer models appear to be even more problematic.

The research published in the journal Astronomy and Astrophysics underscores the urgent need for regulatory measures to mitigate the impact of satellite constellations on scientific research. With predictions that the number of satellites in orbit could exceed 100,000 by 2030, the potential for further interference grows.

Professor Dempsey advocates for regulatory action and technical solutions, such as improved shielding of satellite components, to reduce radiation. Without these measures, astronomers fear that the night sky will become increasingly dominated by artificial signals, overshadowing the natural celestial wonders.

The findings highlight a growing tension between the expansion of satellite networks and the preservation of scientific observation, underscoring the need for a balanced approach to space exploration and research.

Engine Fire on Cathay Pacific Airbus A350 Linked to Fuel Leak, Investigators Reveal

Published

An engine fire aboard a Cathay Pacific Airbus A350 earlier this month was caused by a fuel leak, according to an investigation by Hong Kong’s Air Accident Investigation Authority (AAIA). The incident, which occurred in early September, prompted the airline to ground its A350 fleet following a turn-around flight due to an “engine component failure.”

The engine involved, a Rolls-Royce Trent XWB-97, suffered a malfunction shortly after departing from Hong Kong en route to Zurich. Pilots received a cockpit fire warning, shut down the affected engine, and deployed fire extinguishers. The aircraft, carrying 348 passengers and crew, made a safe emergency landing back in Hong Kong.

A preliminary report from the AAIA indicates that a broken fuel hose—among several damaged hoses—caused the fire. The protective cover of the fuel hose had ruptured, creating a “discernible hole” and leaving signs of soot and burn marks. The report highlights that other defective fuel hoses in the same engine could have led to a more severe fire if not promptly addressed.

The AAIA has recommended that the European Union Aviation Safety Agency (EASA) mandate new inspection protocols for the Trent XWB engines. In response, EASA has introduced inspections of fuel pipes and the removal of potentially compromised hoses. The agency also broadened its inspection requirements to include multiple variants of the Trent XWB engine after discovering that a specific cleaning process during engine refurbishment could degrade the fuel hoses.

Cathay Pacific has stated that it conducted a comprehensive fleet-wide inspection of its A350 aircraft and is fully compliant with EASA’s directives. The airline assured that it continues to collaborate closely with airframe and engine manufacturers as well as regulators to ensure safety.

The Airbus A350, which first entered service in 2016, is favored for its efficiency and low operating costs. The Trent XWB engine, developed by Rolls-Royce specifically for the A350, is central to the aircraft’s performance. Although the fire raised concerns about potential widespread issues affecting the global A350 fleet, it was soon determined that the problem was limited to the external fuel lines, not the engine’s internal components.

Rolls-Royce has committed to supporting the ongoing investigation and emphasized that the engine and aircraft systems effectively managed the incident. The company is also investing in improvements to its engine range, including the Trent XWB-97, in response to industry feedback.

The incident underscores the importance of rigorous safety inspections and timely responses to potential aviation hazards, ensuring continued confidence in the Airbus A350 and its Trent XWB engines.

Samsung Electronics Faces Major Disruption in India Amid Prolonged Worker Strike

For the past 11 days, around 1,500 workers at Samsung Electronics’ Chennai plant in Tamil Nadu have been on strike, causing significant disruptions to production. The Chennai facility, one of Samsung’s two factories in India, employs nearly 2,000 workers and is crucial to the company’s revenue, contributing about a third of its annual $12 billion (£9 billion) earnings from India.

The striking workers are demanding recognition of their newly-formed union, the Samsung India Labour Welfare Union (SILWU). They argue that only a union can effectively negotiate better wages and working conditions. The protest, one of Samsung’s largest in recent years, comes amid Prime Minister Narendra Modi’s efforts to attract foreign investment by positioning India as an alternative to China for manufacturing.

Samsung India has stated that worker welfare is a priority and that discussions are ongoing to resolve the issues. “We have initiated discussions with our workers at the Chennai plant to resolve all issues at the earliest,” the company said.

Earlier in the day, police detained around 104 workers for participating in an unauthorized protest march but released them later. The workers have vowed to continue their strike indefinitely until their demands are met. According to A Soundararajan from the Centre of Indian Trade Unions (CITU), which supports the new union, the workers are asking for union recognition, collective bargaining rights, and the exclusion of competing unions. About 90% of the workforce is reportedly aligned with SILWU.

The striking workers, who earn an average monthly salary of 25,000 rupees ($298; £226), are seeking a 50% raise over the next three years. They also allege unsafe working conditions, including excessive pressure to meet production targets and prolonged work hours without adequate breaks. Samsung India has denied these allegations, asserting that all workers receive suitable breaks and work in compliance with labor laws.

Tamil Nadu’s Labour Welfare Minister CV Ganesan has assured union officials that talks are underway to address their concerns. “We will fulfill the demands of the workers,” he said.

The protest highlights ongoing issues in India’s labor market, where multinational corporations often face criticism for inadequate labor practices. Labor economist Shyam Sundar notes that firms frequently use strategies to prevent unionization, such as promoting internal, company-controlled unions over external ones. He also points to the rise of contractual labor, which can be used to maintain a more compliant workforce.

As global companies, including Apple and Amazon, establish operations in India, labor rights activists argue that many underpay and overwork employees while resisting compliance with local labor laws. The situation at Samsung’s Chennai plant reflects broader challenges facing workers in India’s rapidly evolving industrial sector.

Bank of England Holds Interest Rates at 5%, Signals Gradual Rate Cuts Ahead

The Bank of England has maintained its base interest rate at 5%, with Governor Andrew Bailey indicating a gradual reduction in borrowing costs may be on the horizon. Bailey noted that while inflation has decreased significantly, the Bank will require more evidence of sustained low inflation before implementing further rate cuts.

Inflation remained at 2.2% last month, slightly above the Bank’s target. The decision to hold rates was widely anticipated, following a reduction from 5.25% in August—the first cut since the pandemic began in 2020. Bailey expressed optimism about future rate decreases but stressed the importance of caution to avoid cutting rates too quickly or excessively.

“The decision to keep rates steady was guided by the need to address persistent inflationary pressures,” Bailey said. He added that inflation must remain low to justify any further reductions. The base interest rate influences borrowing costs, affecting mortgages, credit cards, and savings returns. While higher rates have led to increased borrowing costs, they have also benefited savers.

The elevated rates have impacted many households, including James and Sofia, who recently moved to a smaller home due to rising rent. Their rent had increased by £100 a month to £1,650, prompting their move to a £1,400 rental property. Sofia, who had to return to work early from maternity leave due to financial strain, reported challenges such as relying on food banks and struggling with fuel costs.

Despite these issues, the Bank of England’s latest assessment suggests some positive economic developments. Mortgage approvals have risen to their highest level since September 2022, and there are reports of improving real incomes. However, the Bank anticipates inflation will climb to around 2.5% towards the end of the year, with the UK economy showing signs of gradual improvement.

Bailey noted that the economic impact of major global events, including the Covid-19 pandemic and the Ukraine war, has lessened. “We’ve managed to navigate past the severe effects of these global shocks,” he said, though he acknowledged that economic recovery has been slow. The Bank expects economic growth between July and September to be 0.3%, down from the 0.4% expansion previously anticipated.

The UK economy has experienced sluggish growth in recent years, prompting the new Labour government to pledge reforms aimed at revitalizing economic performance. The Bank of England’s cautious approach reflects ongoing concerns about inflation and economic stability as it looks to balance rate adjustments with broader economic conditions.
