 Defence Research and Development Organisation (DRDO) has achieved a significant milestone in hypersonic propulsion technology by successfully conducting a long-duration ground test of its scramjet engine. On April 25, 2025, the Defence Research & Development Laboratory (DRDL) in Hyderabad tested an Active Cooled Scramjet Subscale Combustor for over 1,000 seconds at the newly established Scramjet Connect Test Facility.    This test marks a substantial advancement from a previous 120-second trial conducted in January 2025, demonstrating DRDO’s growing expertise in sustaining supersonic combustion over extended periods. The successful operation of the…

The Ministry of Coal’s recent introduction of new incentives marks a significant shift in India’s strategy towards domestic coal production, specifically targeting the oft-overlooked potential of underground mining. These incentives, designed to bolster production and attract investment, represent a crucial move to enhance energy security and reduce reliance on imports. While surface mining has historically dominated India’s coal landscape, underground mining offers advantages in terms of environmental impact, land utilization, and the extraction of deeper coal seams inaccessible by open-cast methods.   The success of this initiative hinges on several…

A new study has accurately estimated the abundance of Helium in our Sun for the first time. This could be a major step in assessing the opacity of the Sun’s photosphere.   Astronomers have traditionally assumed the abundance of Helium in the photosphere of Sun-like stars to be one tenth of that of Hydrogen by extrapolating from hotter stars, or from the outer atmosphere of the Sun (solar corona, solar wind), or from seismology studies of the interior of the Sun. None of these methods are based on direct observations…
