Sentinel-5A, a new satellite launched in August 2025, has begun providing detailed images of Earth's atmosphere, including the ozone hole over Antarctica, pollution levels over urban areas, and natural emissions from volcanoes and wildfires, enhancing global environmental monitoring.
A Falcon 9 rocket launched the European MTG-S1 weather satellite on July 1, which is designed to collect weather data and monitor atmospheric pollution, marking a significant step in European space capabilities.
A recent study by Canadian and French researchers found that drug-resistant bacteria can be carried by clouds over long distances, potentially becoming a major health concern worldwide. The bacteria were found in cloud samples taken from an atmospheric research station in central France, with an average of around 8,000 bacteria per milliliter. The study did not offer conclusions on the potential health effects of the spread of antibiotic-resistant bacteria in the atmosphere, but atmospheric monitoring could help pinpoint sources and limit their dispersal.
