Mission Study

• NASA has selected the Dynamic Atmosphere-Ionosphere Explorer (DAPHNE) mission concept to investigate the relationship between Earth's atmosphere and space weather. • The mission will specifically research how atmospheric dynamics and space weather influence the surrounding space environment. • This study is critical for improving our understanding of atmospheric waves and auroras, which can impact satellite communications and navigation systems.

Imperial College scientists analysed health records before and after introduction of air pollution reduction zonesLow emission and clean air zones attract controversy whenever they are proposed, but there is growing evidence that they work in improving air quality. The Bradford zone was followed by a reduction of about 25% in GP visits for heart and breathing problems and survey data shows that the central London zone was followed by a reduction in the likelihood of a person taking sick leave.Now analysis of health records has found emergency admissions to hospital reduced after the introduction of the T-charge and ultra-low emissions zone (Ulez) in central London.

• A comprehensive analysis from the National Center for Atmospheric Research shows US carbon dioxide emissions fell 8.2% year-over-year in Q1 2026, driven primarily by renewable energy sources now supplying 34% of national electricity generation. • Solar and wind capacity additions reached record levels with 42 gigawatts of new renewable infrastructure installed in 2025, according to data released by the Department of Energy and independent research institutions. • Climate scientists attribute the acceleration partly to state-level climate policies and federal incentives from the 2024 Clean Energy Investment Act, though transportation and industrial sectors still require significant emission reductions.

• Researchers from Harvard T.H. Chan School of Public Health published findings on March 19 in Environmental Health Perspectives linking fine particulate matter (PM2.5) exposure to a 3.2% increase in cardiovascular hospital admissions within two days in major US metropolitan areas. • The analysis of 15 million hospital records across 50 US cities over 12 years found that a 10 microgram per cubic meter increase in PM2.5 correlates with approximately 4,200 additional cardiovascular hospitalizations annually across studied cities. • The research supports EPA air quality standards and highlights urgent need for pollution control measures, as cardiovascular disease remains the leading cause of death in the United States affecting 126 million Americans.
