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 ...

Two Spacecraft Recreate Artificial Solar Eclipses to Observe the Sun’s Superhot Corona
Twin satellites in ESA’s Proba-3 mission have successfully recreated artificial solar eclipses from space to examine the sun’s million-degree corona. The breakthrough will allow continuous observations of the sun’s outer atmosphere, offering rare insights that natural eclipses on Earth can’t provide. The mission marks a major step in solar ...

ESA's Proba-3 Unveils First-Ever Artificial Solar Eclipse Images from Precision Satellite Formation
ESA’s Proba-3 mission has captured the first artificial solar eclipse from space using two satellites flying in precise formation. This breakthrough allows frequent, high-resolution imaging of the sun’s corona, bypassing the rarity of natural eclipses. The mission opens new frontiers in solar physics and space weather research with open access ...

AI Reveals Mars’s Mysterious Slope Streaks Likely Formed by Dust, Not Water Activity
An AI-based study has found that Mars’s mysterious dark slope streaks are likely formed by dust and wind, not flowing water as long believed. Based on an analysis of over 86,000 satellite images, the findings challenge past theories and may help scientists focus future Mars missions on more promising areas in the search for ancient life.

China Launches AI-Powered Satellite Constellation to Build Space Supercomputer
On May 14, China launched the first 12 satellites of its Three-Body Computing Constellation, an ambitious project led by ADA Space and Zhejiang Lab. Set to include 2,800 satellites with a combined capacity of 1,000 peta operations per second, this space-based AI network uses natural cooling in orbit and high-speed laser communications. Designed to ...

NASA Spots Plankton Swarms from Space to Help Save North Atlantic Right Whales
North Atlantic Right Whales are one of the world’s most endangered mammals. They face threats from fishing gear entanglement and ship collisions. Scientists are now using NASA satellite data to track the whales’ key food source, the red coloured plankton Calanus finmarchicus, in the Gulf of Maine. By identifying swarms of this copepod via its n...

Chorus Waves Found Far From Earth Raise Concerns for Space Exploration
Chorus waves, energetic electromagnetic bursts resembling bird chirps, have been detected 100,000 miles from Earth, far beyond their usual range. NASA's Magnetospheric Multiscale satellites observed these waves in a flatter region of Earth's magnetosphere, contradicting prior assumptions about their formation near strong magnetic gradients. The wav...

Satellite Captures Svalbard Bear Island's Rare Cloud Formations and Algal Bloom
A 2023 satellite image captured algal bloom and atmospheric vortices near Bear Island in Norway’s Svalbard archipelago. The algal bloom, stretching 400 kilometres, formed vibrant spirals due to ocean currents. Atmospheric vortices, caused by airflow disruption over Miseryfjellet mountain, mirrored these patterns in the sky. Bear Island’s radioa...
