Target Prelims 2024: Day 19:
1. OSIRIS-Rex mission:
**NASA's Origins-Spectral Interpretation-Resource Identification-Security-Regolith Explorer (OSIRIS-Rex) mission is set to drop a capsule containing samples from the asteroid Bennu to Earth.
• It is a spacecraft that traveled to an asteroid named Bennu and collected a sample of rocks and dust from the surface.
• This mission will help to investigate how planets formed and how life began, as well as improve the understanding of asteroids that could impact Earth.
• Asteroid Bennu - Named after an Egyptian deity, Bennu is located about 200 million miles away from the Earth.
2. Psyche Mission:
**Psyche mission fires lasers at Earth from 16 million kilometres away, successfully demonstrating the future of communication in space.
• Launched by - NASA in 2023, to study the metallic asteroid called ‘16 Psyche’, located in the main asteroid belt between Mars and Jupiter.
• Mission – By 2029, the spacecraft will begin exploring the asteroid and will spend about 2 years orbiting the asteroid.
• It will take pictures, map the surface, and collect data to determine Psyche’s composition.
3. Carbon-dioxide Auroras:
NASA’s satellite spots infrared carbon dioxide aurora from outer space
• Aurora - When solar storm interacts with the magnetic field lines at the north and south poles into Earth's atmosphere, it results in beautiful displays of light called auroras.
Oxygen gives off green and red light and Nitrogen glows blue and purple.
* In the north, the display is called aurora borealis, or northern lights.
• In the south, it is called aurora australis, or southern lights.
• Other planets (Jupiter, Saturn, Uranus, Neptune) in our solar system have auroras.
• Carbon-dioxide Auroras - While carbon dioxide is known for its effects on the troposphere as a greenhouse gas, it also exists in trace amounts in Earth's atmosphere at the edge of space.
4. Sagar Maitri Mission:
Recently, an oceanographic research vessel ‘INS Sagardhwani’ embarked on Sagar Maitri (SM) Mission-4.
• Sagar Maitri - A novel initiative of DRDO to support Safety and Growth for All in the Region (SAGAR) policy.
• Objective - To promote closer cooperation in socio-economic aspects and long-term scientific partnerships & collaborations with the 8
Indian Ocean Rim (IOR) countries.
• MAITRI – Marine and Allied Interdisciplinary Training and Research Initiative is a scientific component initiated by DRDO under SAGAR Policy
• It establishes long-term collaboration with IOR countries in Ocean Research and Development.
• INS Sagardhwani - A marine acoustic research ship.
**8 IOR countries - Oman, Maldives, Thailand, Malaysia, Singapore, Myanmar, Sri Lanka & Indonesia.
5. Project Udbhav:
**The Indian Army has started an initiative, named Project Udbhav in collaboration with the United Service Institution (USI) of India.
• Aim - To rediscover the Indic heritage of statecraft and strategic thoughts derived from ancient Indian texts of statecraft, warcraft, diplomacy and grand strategy.
• It focuses on indigenous military systems, historical texts, regional texts and kingdoms, thematic studies, and intricate kautilya Studies from 4th century BCE to the 8th century CE.
• The first scholarly outcome of the initiative is the Paramparik Bhartiya Darshan Ranniti aur Netriyta ke Shashwat Niyam.
