SpaceX Sends Sentinel-6B to Orbit for Precision Sea-Level Tracking
SpaceX successfully launched the Sentinel-6B ocean-monitoring satellite on November 17, 2025, marking its 500th orbital mission using a reused Falcon 9 booster. Sentinel-6B will extend more than 40 years of continuous sea-level measurement, delivering high-precision global ocean data as part of Europe’s Copernicus climate program. Equipped with a...

Scientists Develop Eco-Friendly Method to Break Down and Reuse Teflon Plastic
A new “mechanochemical” process allows the recycling of Teflon by grinding it with sodium metal at room temperature. This solvent-free reaction breaks down Teflon’s carbon-fluorine bonds, producing harmless carbon and sodium fluoride instead of toxic PFAS. The sodium fluoride can be reused in fluorine-based products, making this approach a br...

Rising Rocket Launches May Delay Ozone Layer Recovery, Study Finds
A growing number of rocket launches may be compromising the ozone layer's recovery, according to new scientific studies. Chlorine and soot from rockets, along with pollutants released during satellite re-entry, could have long-term environmental impacts. The space industry is urged to act now—through regulation, innovation, and cleaner fuels—to...

NASA and ISRO Prepare to Launch NISAR Earth-Mapping Satellite
NASA and India’s ISRO are set to launch NISAR, a first-of-its-kind Earth-observing satellite equipped with advanced dual-band radar. Scheduled to lift off no earlier than late July 2025 from Sriharikota, India, NISAR will map nearly all of Earth’s land and ice every 12 days, capturing surface changes with centimeter-level precision. Its L-band ...

Climate Satellite MethaneSAT Fails After Just One Year in Orbit
MethaneSAT, a climate-monitoring satellite backed by Google and the Bezos Earth Fund, has failed after just one year in orbit. Launched in March 2024 to track methane leaks, the $88 million satellite lost power in June 2025. Though unrecoverable, mission operators will continue analyzing the collected data to support climate action and emission tra...

Breakthrough Laser Tech Enhances LiDAR Accuracy and Gas Detection
Researchers from NTNU and EPFL have developed a compact, low-cost laser on a photonic chip using thin-film lithium niobate. This new laser enables ultrafast, mode-hop-free tuning and delivers stable performance with a single control knob. Demonstrated in LiDAR systems, it achieved 4 cm range precision for self-driving cars and also detected trace h...

Green Rooftops Could Help Cities Like Shanghai Filter Out Tons of Microplastics from Rainwater
A Tongji University study shows green roofs can trap most rainborne microplastics, with soil capturing the majority. If all Shanghai rooftops went green, they could remove 56.2 metric tons of microplastics each year, highlighting a promising method for tackling urban pollution.
