Approval for Venus Mission “Shukrayaan”

Syllabus :GS 3/Space 

In News

  • The Indian government has approved ISRO’s Venus Orbiting Satellite mission, named Shukrayaan.

Shukrayaan Mission (Venus Orbiting Satellite)

  • Launch Details: Set to launch in March 2028.
    • Estimated cost of the mission is Rs 1,236 crore.
    • LVM-3 launch vehicle has been identified to place the spacecraft in an Elliptical Parking Orbit (EPO)
  • Objectives:
    • Atmospheric Studies: Analyze the composition of Venus’s thick, carbon dioxide-rich atmosphere. Study the extreme greenhouse effect and its impact on the planet’s climate.
    • Surface Mapping: Utilize advanced radar technology to map the planet’s surface, revealing hidden geological features.
    • Ionospheric Studies: Explore the upper atmosphere of Venus, including the ionosphere, to understand its interaction with solar radiation and the solar wind.
  • Scientific Payload:
    • Synthetic Aperture Radar (SAR): To penetrate the thick clouds and map the surface features.
    • Infrared Spectrometer: To study the composition of the atmosphere and surface.
    • Ultraviolet Spectrometer: To analyze the upper atmosphere and ionosphere.

Challenges of the Mission

  • Extreme Environment: Venus’s harsh environment, characterized by high temperatures and acidic atmosphere, poses significant challenges to spacecraft design and operation.
  • Technical Complexity: The mission requires precise navigation and control to achieve its scientific objectives.
  • Data Transmission: Reliable communication between the spacecraft and Earth over long distances is essential.
Facts about Venus
Venus, the second planet from the Sun, is often called Earth’s twin but is a harsh and hellish world. 
– Venus’s atmosphere is incredibly dense, composed primarily of carbon dioxide. This dense atmosphere traps heat from the Sun, creating a runaway greenhouse effect.
– Venus is the hottest planet in the solar system and is named after the goddess of love.
– Venus rotates on its axis in the opposite direction to most other planets, a phenomenon known as retrograde rotation. This means that the Sun rises in the west and sets in the east on Venus.
– Several space missions, including Mariner 2, Venera, and Magellan, have studied Venus, providing valuable insights into its atmosphere, surface, and geology.
– Future missions, such as NASA’s VERITAS and DAVINCI+, aim to further explore Venus.
