12-Jul-2023: Shri Sarbananda Sonowal inaugurates ‘SAGAR SAMPARK’ Differential Global Navigation Satellite System to Strengthen Maritime sector
The Ministry of Ports, Shipping and Waterways is committed towards innovation, building best infrastructure, and strengthening the Indian Maritime sector. Today, to further the digital initiative in maritime sector the Union Minister of Ports, Shipping and Waterways, Shri Sarbananda Sonowal inaugurated the indigenous Differential Global Navigation Satellite System (DGNSS) ‘SAGAR SAMPARK’ in the presence of Shri Shripad Y. Naik, the Minister of State of Ports, Shipping and Waterways; Shri TK Ramachandran, IAS Secretary, MoPSW and other senior officials from the ministry and Directorate General of Lighthouses and Lightships. DGNSS is a terrestrial based enhancement system which corrects the errors and inaccuracies in the Global Navigation Satellite System (GNSS) allowing for more accurate positioning information.
2-Jul-2023: First batch of crew module recovery divers complete training
The first batch of crew recovery team of Mission Gaganyaan completed Phase-1 of training at Indian Navy's Water Survival Training Facility (WSTF) at Kochi. Utilising the state of the art facility, the team comprising of Indian Naval Divers and Marine Commandos underwent recovery training of crew module in varied sea conditions. The two weeks training capsule covered a brief on the conduct of the mission, actions to be taken during medical exigencies and familiarisation with different aircraft and their rescue equipment. The training also validated the SOPs formulated jointly by the Indian Navy and ISRO. On the concluding day, Dr. Mohan M, Director of Human Space Flight Centre, ISRO witnessed the recovery demonstration and interacted with the team. The team trained at WSTF will now be involved in recovery of test launches planned by ISRO in the forthcoming months.
15-Jun-2023: New study reveals higher temperature enhancements during acoustic shocks in the solar chromosphere
A new study has found that bright grains observed in the chromosphere of the Sun are due to upward propagating shocks in the solar plasma, and show higher temperature enhancements than previous estimates. The study can help improve understanding of the mechanism of heating of the chromosphere situated between the bright solar surface and the extremely hot corona.
The chromosphere is a highly active layer within the solar atmosphere and plays a crucial role in transferring energy (specifically non-thermal energy) that heats the corona and fuels the solar wind, which extends outward into the surrounding regions of the solar atmosphere. Although a large portion of this energy is converted into heat and radiation, only a small fraction is actually used to heat the corona and power the solar wind.
