What is cloud seeding? A proposed solution to Delhi's severe air pollution crisis
Delhi is exploring cloud seeding as a potential solution to combat its severe air pollution crisis. The technique involves inducing rainfall to wash away pollutants, but its effectiveness and long-term impact are debated among scientists. While it may offer temporary relief, experts emphasize the need for sustainable solutions addressing the root causes of pollution.

The dark energy pushing our universe apart may not be what it seems, scientists say
Astronomers studying the accelerating expansion of the universe have found that dark energy, the force thought to be responsible, may not be constant as previously believed. New analyses of distant galaxies suggest that dark energy could be changing or weakening over time, potentially challenging the standard cosmological model.
India’s Gsat-20 satellite becomes part of SpaceX’s global launch record
SpaceX achieved a global milestone by launching three Falcon 9 rockets in 20 hours, including one carrying India's advanced communication satellite, GSAT-20. This marked SpaceX's 112th, 113th, and 114th launches of the year. The GSAT-20, weighing 4,700kg, was launched from Cape Canaveral and will significantly enhance India's broadband connectivity.
Isro depended on SpaceX to launch GSAT-N2 as its existing capability was not sufficient: Ex-chiefs
India turned to SpaceX's Falcon 9 rocket to launch its GSAT-N2 communication satellite due to the heavier payload exceeding the capabilities of ISRO's current launch vehicles, said ex-Isro chiefs. While Isro is working on enhancing its launch capacity, the 4,700 kg satellite required a more powerful rocket, highlighting the need for increased capabilities to handle future heavy payloads.
