Rocket Lab Successfully Launches NEONSAT-1A on Bridging the Swarm Mission
Rocket Lab successfully launched South Korea’s NEONSAT-1A satellite on January 29, 2026, completing the delayed Bridging the Swarm mission from New Zealand. Deployed into a 540-kilometer orbit, the Earth-observation spacecraft will deliver near-real-time imagery to monitor natural disasters across the Korean Peninsula. The launch marked Rocket La...

VLT’s GRAVITY Instrument Detects ‘Tug’ from Colossal Exomoon; Could Be Largest Natural Satellite Ever Found
Astronomers have spotted a subtle orbital wobble around the massive exoplanet HD 206893 B, hinting at the presence of a gigantic moon nearly half Jupiter’s mass. If confirmed, it would be unlike any moon known, potentially redefining how scientists distinguish between moons, planets, and brown dwarfs.

Glaciers Speed Up in Summer and Slow in Winter, New Global Map Reveals
A new global map of glacier speeds, built from nearly a decade of satellite observations, shows that glaciers consistently move faster in summer and slower in winter. Meltwater acts as a natural lubricant, accelerating flow during warm months. Scientists warn that glaciers with strong seasonal shifts are likely to speed up long-term, adding to futu...

NOAA’s GOES-19 Satellite Records Rare Eclipse With Distorted Lunar Path
On Sept. 21, 2025, GOES-19’s CCOR-1 coronagraph recorded a natural lunar eclipse. The Moon’s trajectory appeared curved due to a satellite yaw-flip. Unlike L1-based coronagraphs, GOES-19’s orbit enabled this rare capture, helping scientists refine imaging systems and improve understanding of the Sun’s corona.

NASA-ISRO NISAR Satellite Prepares to Deliver Sharpest-Ever Views of Earth
The NISAR satellite, developed by NASA and ISRO, is ready to begin full science operations. Using dual-band radar, it will provide high-precision data on land movement, ice dynamics, vegetation, and natural hazards, supporting global research and disaster management efforts.

How ISRO Is Touching Lives: Parliament To Debate Space Programmes Today
The Indian Space Research Organisation (ISRO), once a modest initiative launched from a church in a fishing village in Thumba, Kerala, has now become a global symbol of frugal innovation and technological excellence.

10 Strange 'Dark Voids' Appear Over Remote Island Near Antarctica in Rare Satellite View
A rare NASA satellite image shows 10 sharply defined “dark voids” above Heard Island, a volcanic peak in the southern Indian Ocean. Formed by von Kármán vortices bent nearly 90 degrees by fierce westerly winds, the striking gaps pierce thick cloud cover, offering a vivid glimpse of nature’s intricate atmospheric patterns from space.

SWOT Satellite Captures Tsunami Wave After Kamchatka Quake
On July 30, 2025, the NASA–CNES SWOT satellite captured the leading edge of a tsunami wave in the Pacific, triggered by an 8.8 magnitude earthquake near Russia’s Kamchatka Peninsula. Recorded about 70 minutes after the quake, the wave measured 1.5 feet in open water but could grow to 30 feet at shore. SWOT’s advanced radar mapped the wave’s...

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 ...
