New Study Reveals Recent Ice Gains in Antarctica, But Long-Term Melting Continues
A study led by researchers at Tongji University using NASA's GRACE satellites has observed recent ice gains in Antarctica from 2021 to 2023, mainly due to unusual precipitation. However, the long-term satellite data from 2002 to 2020 shows a significant and accelerating trend of ice loss. However, experts emphasize this short-term gain does not rev...

28 Major US Cities Are Sinking, Including NYC and Chicago, Satellite Study Finds
A new satellite study has revealed that 28 of the most populous U.S. cities, including New York and Chicago, are sinking by up to 10 millimetres yearly. Researchers found that groundwater extraction is the key driver behind this trend, raising silent but serious threats to infrastructure, even in inland cities not typically prone to such risks.

Scientists Chase Falling Satellite to Study Atmospheric Pollution from Spacecraft Reentries
In a rare airborne mission, scientists chased ESA's Cluster Salsa satellite as it reentered Earth's atmosphere. The fiery descent revealed emissions of lithium, potassium, and aluminum—chemicals that could impact the ozone layer and climate. With satellite reentries increasing, researchers aim to improve pollution models and plan further tracking...

NASA's TRACERS Mission Rescheduled for 2025 to Explore Solar Wind and Earth's Magnetic Field
NASA has delayed its TRACERS mission to no earlier than 2025 to provide additional preparation time for the crew. The mission will send twin satellites to explore how solar wind interacts with Earth's magnetosphere, particularly through a process called magnetic reconnection. These high-speed solar particles can trigger auroras and impact satellite...

NASA's New Satellite Duo Begins Tracking Mysterious Auroral Electrojets
The EZIE mission is shaping up to be a breakthrough in space weather research. Launched in March 2025, its three satellites are now orbiting Earth and collecting data on auroral electrojets, massive energy currents near the poles. Scientists believe the results could lead to better forecasting tools and stronger, safer satellite systems.

Hidden Solar Cycle Could Reshape Space Weather for the Next 50 Years, Finds Study
A hidden solar cycle is emerging, potentially intensifying space weather events over the next 50 years. While this cycle may raise concerns about geomagnetic storms and satellite disruptions, scientists believe it could also offer valuable opportunities to advance space weather forecasting, study Earth's magnetic field, and improve our resilience t...

Two New Exoplanets Found Orbiting a Star in Draco Constellation
Astronomers have identified two exoplanets, TOI-1453 b and TOI-1453 c, orbiting a star 250 light-years away in Draco. The planets, a super-Earth and a sub-Neptune, were detected using NASA’s TESS satellite and the HARPS-N spectrograph. TOI-1453 b is a rocky planet orbiting close to its star, while TOI-1453 c is twice Earth’s size and may have a...

Greenland’s Melting Glaciers Expose 1,620 km of New Coastline Since 2000
Over the past 20 years, Greenland’s glaciers have melted enough to expose 1,620 kilometres of new coastline, altering the Arctic’s geography. Satellite data from 2000 to 2020 tracked these changes, showing significant ice loss. The study also identified 35 newly exposed islands, some of which remain unclaimed on existing maps. Scientists warn o...

NASA to Launch Three Rockets in Alaska to Study Auroral Substorms’ Impact
NASA is conducting a rocket experiment from Poker Flat Research Range in Alaska. Three rockets will launch within a three-hour window to study how auroral substorms influence the Earth's upper atmosphere. Scientists will observe whether auroras drive vertical convection or if acoustic-buoyancy waves spread their energy over a wider region. Vapour t...

NASA’s EZIE Satellites Begin Mission to Study Auroral Electrojets and Space Weather
NASA’s Electrojet Zeeman Imaging Explorer (EZIE) mission has been launched aboard a SpaceX Falcon 9 from Vandenberg Space Force Base. The trio of small satellites will map auroral electrojets, powerful currents in Earth’s atmosphere linked to solar storms. Their data will enhance space weather prediction models and help understand planetary mag...

NASA's MMS Mission Marks 10 Years of Magnetic Reconnection Discoveries
NASA's Magnetospheric Multiscale (MMS) mission has completed a decade of discoveries, advancing the study of magnetic reconnection—a crucial process in space physics. The four-satellite fleet has enabled over 1,500 research papers, refining theories and revealing unexpected reconnection locations. The mission has also set records for GPS tracking...

ISRO Expands with Two Launchpads, Chandrayaan-4 to Launch in 2028 with Lunar Sample Return Mission
Isro is developing two new launchpads in Andhra Pradesh and Tamil Nadu to support its growing space program. Chandrayaan-4, a 9,200 kg mission planned for 2028, will involve a lunar sample return. The organisation is also collaborating with NASA on the NISAR satellite for environmental monitoring. In the past decade, Isro has launched 433 satellite...

Tiny Plasma Jets on Sun Identified as Key Drivers of Solar Wind
Observations from ESA’s Solar Orbiter have revealed that tiny plasma jets, known as picoflares, are responsible for both the fast and slow components of the solar wind. The discovery challenges previous assumptions that different mechanisms drive these solar wind types. With further research, scientists hope to refine space weather predictions, p...

NASA’s PUNCH Mission Set to Track the Sun’s Corona and Solar Wind in 3D
NASA’s PUNCH mission, set for launch on Feb 27, will deploy four satellites to study the transition between the sun’s corona and the solar wind. The mission aims to improve understanding of space weather by capturing 3D images, helping predict solar storms with greater accuracy. The data will also complement NASA’s Parker Solar Probe, offerin...
