India's First Solar Observatory Aditya L1 Reaches Its Destination Halo Orbit

India's first solar observatory Aditya-L1 achieved a major milestone as it reached the Halo Orbit's L1 point, a unique spot in space outside the orbit of the Moon to give a clear view of the Sun throughout the year. Prime Minister Narendra Modi congratulated the achievement.
Objects positioned at L1 remain in a stable configuration relative to the Earth and the Sun, making it an advantageous location for certain types of satellites, like those used for solar observations or monitoring space weather. However, maintaining a satellite at L1 requires constant adjustments due to gravitational perturbations from other celestial bodies.

ISRO Tests Fuel Cell on PSLV-C58's POEM3 Platform Successfully

The Indian Space Research Organisation (ISRO) achieved a significant milestone by successfully testing a 100 W class Polymer Electrolyte Membrane Fuel Cell based Power System (FCPS) in its orbital platform, POEM3. This remarkable feat took place aboard the PSLV-C58 mission, marking a crucial step in the assessment of fuel cell technology for future space missions.
The primary objective of the experiment was to evaluate the operation of Polymer Electrolyte Membrane Fuel cells in the challenging environment of space. Additionally, the mission aimed to gather valuable data to inform the design of power systems for upcoming space endeavours.

China's Groundbreaking Voyage: Mengxiang Sets Sail for Earth's Mantle Exploration

China introduced its groundbreaking ocean drilling vessel, Mengxiang, signifying a pivotal moment in scientific exploration. Developed by the China Geological Survey in collaboration with 150 research institutes and companies, the vessel is named "dream" in Chinese, reflecting its ambitious mission. The Mengxiang aims to penetrate Earth's crust and delve into the mysteries of the mantle, marking humanity's inaugural foray into this uncharted territory.
Mengxiang is a colossal ship with exceptional capabilities. It boasts a range of 15,000 nautical miles and can operate for 120 days per port call. Engineered to withstand powerful tropical cyclones, it stands as a testament to advancements in deep-sea drilling technology. The vessel's drilling prowess is unmatched, with the capacity to reach depths of 11,000 metres below the sea's surface.
Traditionally confined to the Earth's crust, scientific exploration now eyes the mantle, a crucial layer connecting the surface to the core. The Mengxiang seeks to breach the Mohorovicic discontinuity, or Moho, the final frontier for human exploration into the mantle. While American scientists have pursued this goal since the 1960s, Mengxiang's cutting-edge technology represents a new chapter in the quest for understanding Earth's structure.

Scientists Discover Plant Growth-promoting Bacteria, Names it after Rabindranath Tagore

Researchers from Visva-Bharati University's botany department identified a bacterium with remarkable potential to enhance plant growth. Named 'Pantoea Tagorei' in homage to Nobel laureate, the bacteria could revolutionise agricultural practices, said microbiologist Bomba Dam, who led the research.
Dam was assisted by research scholars Raju Biswas, Abhijit Mishra, Abhinav Chakraborty, Pooja Mukhopadhyay and Sandeep Ghosh. The team isolated the bacteria from the soil of Sonajhuri in Santiniketan and then discovered the same in the coal mining belt in Jharkhand's Jharia.
The Association of Microbiologists of India officially recognised this discovery.
