India has officially greenlit Chandrayaan-4, a 2028 lunar sample-return mission set to bring home 3 kg of Moon soil. The mission involves five spacecraft docking in Earth orbit before heading to the lunar surface. ISRO is also moving ahead with its Bharatiya Antariksh Station, with the first module planned for 2028 and full completion targeted for 2035.

SpaceX successfully launched the Sentinel-6B ocean-monitoring satellite on November 17, 2025, marking its 500th orbital mission using a reused Falcon 9 booster. Sentinel-6B will extend more than 40 years of continuous sea-level measurement, delivering high-precision global ocean data as part of Europe’s Copernicus climate program. Equipped with advanced radar and mi...

As lunar exploration surges, scientists warn that the Moon’s limited stable orbits are growing crowded. Georgia Tech simulations suggest that with about 50 satellites, each may need several collision-avoidance maneuvers per year. Even now, orbiters like Chandrayaan-2 require frequent course corrections. With Artemis and private missions incoming, agencies are develo...

Astronomers using ESO’s Very Large Telescope have captured a rare early look at supernova SN 2024ggi, just one day after its discovery. The blast shockwave appeared olive-shaped—not spherical—revealing surprising asymmetry in the explosion. Recorded with the FORS2 instrument, the data shows the shock-breakout phase in unprecedented detail. The discovery challeng...

Researchers at the University of Houston find boron arsenide conducts heat better than diamond, reshaping thermal management in electronics.
