India's-third-moon-mission-Chandrayaan-3On 14 July 2023, India successfully launched Chandrayaan-3 with LVM3-M4 rocket from Satish Dhawan Space Center in Sriharikota.

An Overview of the news:

  • With the success of ISRO's Chandrayaan-3 mission, India will be the fourth country after Russia (Soviet Union), America and China to have soft-landed on the Moon.
  • ISRO launched Chandrayaan-1 in 2008. Chandrayaan-2 was launched in 2019. Chandrayaan-3 was launched from Sriharikota on 14 July 2023.

Propulsion Module, Lander and Rover of Chandrayaan-3:

  • In Chandrayaan-2 where there were Orbiter, Lander and Rover. Whereas, Chandrayaan-3 has a propulsion module, lander and rover.
  • The Lander + Rover of Chandrayaan-3 weighs about 250 kg more than the Lander + Rover of Chandrayaan-2.

How long will the missions last:

  • While Chandrayaan-2 had a mission life of 7 years (estimated), Chandrayaan-3's propulsion module is designed to work for 3 to 6 months.
  • Chandrayaan-3 will move towards the moon more quickly than Chandrayaan-2.
  • 4 thrusters have been installed in the lander of Chandrayaan-3. After a journey of about 40 days, Chandrayaan-3 will reach the surface of the moon. Chandrayaan-2 took 42 days to reach the moon.

Mission Cost:

  • The cost of launching this mission is Rs 615 crore. While it has cost Rs 500 crore to launch it.

Mission Objective:

  • The Chandrayaan-3 mission aims to gather more information about the lunar surface. For this, four types of scientific instruments have been installed on the lander. Which mainly:

    • Earthquakes on the moon
    • Surface thermal properties,
    • Variation in plasma near the surface,
    • Attempt to measure the exact distance between the Moon and the Earth,
    • Will study the chemical and mineralogical composition of the lunar surface.

4. Megasiphon Thylacos, a new fossil species of tunicate discovered

Tags: Environment Science and Technology

Megasiphon Thylacos, a new fossil species of tunicate discoveredResearchers recently described a new fossil species of tunicate called Megasiphon Thylacos

An Overview of the News

  • The Megasiphon Thylacos fossil is about 500 million years old.

  • The discovery suggests that the modern tunicate body plan was established shortly after the Cambrian explosion.

  • The fossil provides insight into the sedentary, filter-feeding lifestyle of ancestral tunicates and their metamorphosis from tadpole-like larvae.

About Tunicates

  • Tunicates, commonly known as sea squirts, are a group of marine animals.

  • They spend most of their lives attached to surfaces such as docks, rocks or the bottom of a boat.

  • There are about 3,000 species of tunicates in the world's oceans, mainly in shallow water habitats.

  • The evolutionary history of tunicates dates back at least 500 million years.

Tunicate Lineage:

  • Ascidians: Ascidians, often called "sea wasps", are one of the main tunicate lineages.

  • They begin their lives as mobile, tadpole-like larvae.

  • As they mature, they undergo metamorphosis and turn into barrel-shaped adults with two siphons.

  • Ascidians spend their adult lives attached to the ocean floor.

  • Appendicularians: The Appendicularias represent another Angrakha dynasty.

  • They retain their tadpole-like appearance even when they become adults.

  • They float freely in the upper water.

  • They appear to be more distantly related to vertebrates than to ascidians.

Physical Characteristics and Feeding Mechanism:

  • The body of adult tunicates is usually barrel-shaped.

  • They have two siphons coming out of their body.

  • A siphon draws water along with the food particles using suction.

  • The other siphons the filtered water back out.

6. Chandrayaan-3 vs. Chandrayaan-2: A Comparison of India's Moon Missions

Tags: Science and Technology

Chandrayaan-3-vs.-Chandrayaan-2-A-Comparison-of-India's-Moon-MissionsWhy in News?

India’s third mission to the moon - Chandrayaan-3 - will take off on 14th July, 2023. The mission aims to achieve what its predecessor - Chandrayaan-2 could not - land softly on the lunar surface and explore it with a rover. A last-minute glitch led to the failure of the lander's (Vikram) soft landing attempt after a successful orbital insertion.

About The Chandrayaan-3 Mission:

  • Chandrayaan-3 ("mooncraft") is a planned 3rd lunar exploration mission by the ISRO to demonstrate end-to-end capability in safe landing (through the lander Vikram) and roving (through the rover Pragyan) on the lunar surface. 

  • Unlike Chandrayaan-2, it will not have an orbiter, and its propulsion module will behave like a communications relay satellite.

Comparing Chandrayaan 2 and 3 Missions:

  • Chandrayaan-2 and Chandrayaan-3 have similar objectives of landing on the moon and exploring its surface with a rover. 

  • However, there are several changes and improvements in the mission design of Chandrayaan-3 based on the lessons learned from Chandrayaan-2's failure.

Changes in the Mission Design:

  • Expanded Landing Area: Chandrayaan-3 has been given instructions to land safely anywhere in a 4kmx2.4km area, unlike the specific 500mx500m patch targeted by Chandrayaan-2.

  • Increased Fuel Capacity: The lander in Chandrayaan-3 has been provided with more fuel to travel longer distances to the landing site or an alternate landing site.

  • Enhanced Landing Site Determination: Instead of relying solely on pictures taken during descent, high-resolution images from Chandrayaan-2's orbiter have been used to feed the lander with location information.

  • Modified Lander Structure: Changes have been made to the lander's physical structure, including the removal of one thruster, strengthening of the legs for higher velocity landings, and the addition of more solar panels.

Chandrayaan-3 Payloads:

  • Propulsion Module: It carries the Spectro-polarimetry of HAbitable Planet Earth (SHAPE) payload to search for smaller habitable planets.

  • Lander Payloads: Chandrayaan-3's lander carries four payloads - Radio Anatomy of Moon Bound Hypersensitive ionosphere and Atmosphere (RAMBHA), Chandra’s Surface Thermophysical Experiment (ChaSTE), Instrument for Lunar Seismic Activity (ILSA), and Langmuir Probe (LP).

  • Rover Payloads: The rover, Pragyan, is equipped with the Alpha Particle X-ray Spectrometer (APXS) and Laser Induced Breakdown Spectroscopy (LIBS) for analysing the elemental composition near the landing site.

How will the Mission be Implemented?

  • The mission will be implemented by launching the lander-rover configuration into a 100-km lunar orbit using a propulsion module. 

  • Once safely on the moon, the lander module (Vikram) will deploy the rover (Pragyan) to perform in-situ chemical analysis of the lunar surface.

Different Kinds of Moon Missions that have been Launched so far:

  • Moon missions can be categorized into flybys, orbiters, impact missions, landers, rovers, and human missions. 

  • Chandrayaan-3 falls under the landers and rovers category, aiming for a soft landing and mobile exploration on the lunar surface.
