SpaceX Launches IMAP, CGO, SWFO-L1 to Probe Solar Frontier and Space Weather
A Falcon 9 lifted off from Kennedy Space Center on Sept. 24, 2025, carrying NASA’s IMAP, CGO, and SWFO-L1 spacecraft. The mission aims to chart the heliosphere’s boundary, monitor Earth’s geocorona, and deliver constant space-weather alerts, protecting satellites and astronauts while expanding knowledge of the solar system’s outer edge.

Satellite Observations Record Arctic Sea Ice at Lowest Level of the Year
NASA satellites recorded Arctic sea ice at 1.78 million sq miles on Sept. 10, 2025—its tenth-lowest extent. Antarctic ice also stayed below seasonal averages. Scientists stress these lows reflect long-term climate-driven changes reshaping Earth’s polar regions.

Astronomers Capture Sharpest-Ever Solar Flare Images with NSF’s DKIST Telescope
Astronomers have achieved a major breakthrough by capturing the sharpest images of a solar flare ever recorded, using the National Science Foundation’s Daniel K. Inouye Solar Telescope (DKIST). Observed at the hydrogen-alpha wavelength during the decay of an X1.3-class solar flare, the images unveiled hundreds of ultra-fine coronal loops averagin...

NASA-ISRO Earth Observation Satellite Unfolds Giant Radar Antenna in Space
NASA and ISRO’s joint NISAR mission has successfully deployed its 12-meter radar reflector in orbit. This unique satellite, carrying dual L-band and S-band radars, will monitor Earth’s glaciers, volcanoes, earthquakes, and ecosystems with unmatched accuracy. The milestone reflects decades of research and showcases the strength of U.S.-India spa...

Ariane 6 Launches Metop-SGA1 Weather Satellite into Polar Orbit
Europe’s heavy-lift Ariane 6 rocket completed its third successful launch on Aug. 12, 2025, lifting off from Kourou, French Guiana at 8:37 p.m. EDT. The mission carried Metop-SGA1, an 8,900-pound next-generation polar-orbiting weather satellite operated by EUMETSAT. Placed into an 800 km polar orbit 64 minutes after liftoff, Metop-SGA1 will deliv...
