The ozone hole over the Antarctic was small in 2025 compared to previous years and remains on track to recover later this century. The hole this year was the fifth smallest since 1992, the year a landmark international agreement to phase out ozone-depleting chemicals began to take effect.

NASA Tests Scalable Satellite Tech to Launch Sensors Quicker
NASA’s Athena Economical Payload Integration Cost mission, or Athena EPIC, is a test launch for an innovative, scalable space vehicle design to support future missions. The small satellite platform is engineered to share resources among the payloads onboard by managing routine functions so the individual payloads don’t have to. This technology results in lower costs […]
Studying Storms from Space Station
Science in Space June 2025 Scientists use instruments on the International Space Station to study phenomena in Earth’s ionosphere or upper atmosphere including thunderstorms, lightning, and transient luminous events (TLEs). TLEs take many forms, including blue jets, discharges that grow upward into the stratosphere from cloud tops, and colorful bursts of energy above storms called […]
NASA Tracks Snowmelt to Improve Water Management
As part of a science mission tracking one of Earth’s most precious resources – water – NASA’s C-20A aircraft conducted a series of seven research flights in March that can help researchers track the process and timeline as snow melts and transforms into a freshwater resource. The agency’s Uninhabited Aerial Vehicle Synthetic Aperture Radar (UAVSAR) […]
Testing in the Clouds: NASA Flies to Improve Satellite Data
In February, NASA’s ER-2 science aircraft flew instruments designed to improve satellite data products and Earth science observations. From data collection to processing, satellite systems continue to advance, and NASA is exploring how instruments analyzing clouds can improve data measurement methods. Researchers participating in the Goddard Space Flight Center Lidar Observation and Validation Experiment (GLOVE) […]
NASA Measures Moonlight to Improve Earth Observations
Flying high above the clouds and moon-gazing may sound like a scene from a timeless romance, but NASA did just that in the name of Earth science research. In March 2025 pilots took the agency’s ER-2 science aircraft on a series of night flights over NASA’s Armstrong Flight Research Center in Edwards, California, as the […]
NASA Uses New Technology to Understand California Wildfires
The January wildfires in California devastated local habitats and communities. In an effort to better understand wildfire behavior, NASA scientists and engineers tried to learn from the events by testing new technology. The new instrument, the Compact Fire Infrared Radiance Spectral Tracker (c-FIRST), was tested when NASA’s B200 King Air aircraft flew over the wildfires […]
