Jacaranda mimosifolia
Jacaranda mimosifolia is a sub-tropical tree native to south-central South America that has been widely planted elsewhere because of its attractive and long-lasting violet-colored flowers. In its native range in the wild, J. mimosifolia is listed as Vulnerable by the IUCN. The jacaranda is regarded as an and Queensland, invasive species in parts of South Africa, Australia, where it can out-compete native species. New species of damselfly
● A group of researchers has discovered a new species of damselfly in the Wayanad landscape of the Western Ghats, Kerala. Named Euphaea wayanadensis, this species marks Kerala’s 191st recorded odonate species (including dragonflies and damselflies), and the 223rd one to be documented from the Ghats.
● The new species belongs to the family Euphaeidae North Sentinel Island Chandrayaan-3 & ChaSTE On August 23, 2023, the Vikram lander of India’s Chandrayaan-3 mission successfully landed on the moon. This event marked a significant milestone in lunar exploration, particularly in the moon’s south pole region. The Vikram Lander: A Marvel of Engineering. The Touchdown: A Moment of Triumph. The Vikram lander carried a thermal probe designed to gather crucial data from the moon’s soil. This achievement was celebrated by scientists and engineers worldwide.
Meet ChaSTE:
Chandra’s Surface Thermophysical Experiment. The Role of ChaSTE in Lunar Research ChaSTE was the first instrument to measure temperatures near the moon’s south pole. It revealed that water ice is more prevalent than previously thought, supporting future lunar missions. Measuring Temperatures Near the Moon’s South Pole ChaSTE provided accurate temperature readings, essential for understanding the moon’s environment. The Technology Behind ChaSTE: The Deployment Mechanism Explained ChaSTE features a sophisticated deployment mechanism with ten temperature sensors.
These sensors are spaced 1 cm apart, allowing for a comprehensive temperature profile. How the Probe Works: A Step-by-Step Breakdown The probe’s motor rotates, pushing the needle into the lunar soil. As it descends, the soil’s resistance increases, providing feedback for accurate tracking. The Significance of Water Ice Discovery Implications for Future Lunar Missions. The discovery of water ice is crucial for future lunar bases, providing resources like oxygen and hydrogen.
