SHUKRAYAAN

SHUKRAYAAN

1. Context

Two Months after the successful Moon landing and launch of a mission to study the Sun, Prime Minister Narendra Modi announced recently two new targets for the space agency ISRO setting up an Indian space station by 2035 and taking the first Indian to the Moon by 2040. The Prime Minister also called on the scientists to work towards a Venus Orbiter Mission and a Mars Lander Mission.

2. Shukrayaan (Venus Orbiter Mission)

The Venus Orbiter Mission, unofficially known as Shukrayaan, is a planned Indian Space Research Organisation (ISRO) mission to study the surface and atmosphere of Venus. It is expected to launch in 2024.

Key features of the mission

  • The spacecraft will orbit Venus for four years, enabling a comprehensive study of the planet's dynamic atmosphere and surface features.
  • The mission will carry a suite of scientific instruments, including a high-resolution camera, an atmospheric spectrometer, and a plasma analyzer, to gather detailed information about Venus's atmosphere, surface composition, and ionosphere.
  • The mission aims to shed light on the evolution of Venus, particularly its transition from a potentially habitable planet to its current harsh environment. It will also investigate the planet's unique atmospheric dynamics and greenhouse effect, providing insights into climate change processes.
  • The mission will involve collaboration with international space agencies, such as NASA, which will contribute a Synthetic Aperture Radar (SAR) instrument to map Venus's surface at high resolution.
  • The mission will push the boundaries of spacecraft design and engineering, as it will need to withstand the extreme conditions of Venus's atmosphere and surface. This will contribute to India's growing expertise in space technology.
 3. The Indian Human Spaceflight Programme (IHSP) and Gaganyaan

The Indian Human Spaceflight Programme (IHSP), spearheaded by the Indian Space Research Organisation (ISRO), is a pivotal initiative that aims to establish India's capability to launch and safely return humans to low Earth orbit. At the heart of this program lies the ambitious Gaganyaan mission, India's first crewed spaceflight endeavour.

3.1. Objectives of the IHSP

The IHSP embodies India's aspirations to become a self-reliant spacefaring nation and pursue human spaceflight missions independently. Its primary objectives include:

  • To develop and showcase India's indigenous technological expertise in launching and recovering humans from space.
  • To conduct scientific experiments in the unique microgravity environment of space, contributing to advancements in various fields.
  • To ignite national pride and inspire the youth, particularly in pursuing STEM education and careers in space exploration.
3.2. Gaganyaan Mission -India's First Crewed Spaceflight

The Gaganyaan mission, meaning "Sky Craft" in Sanskrit, is the first step in realizing the IHSP's vision. It is scheduled to launch in 2024, carrying three Indian astronauts to orbit Earth for seven days.

  • The Gaganyaan mission will utilize the Geosynchronous Satellite Launch Vehicle Mark III (GSLV Mk III), India's most powerful rocket, to launch the crew module into a low Earth orbit of approximately 400 kilometres.
  • The crew module will accommodate the three astronauts and provide a habitable environment during their week-long mission. The astronauts will undergo rigorous training, including simulations, physical conditioning, and psychological preparation.
  • The mission will carry a suite of scientific experiments to be conducted in microgravity, covering areas such as material science, bioscience, and space medicine.
3.3. Significance of the IHSP and Gaganyaan

The successful execution of the IHSP and the Gaganyaan mission will mark a significant milestone in India's space exploration journey. It will:

  • Place India among an elite group of nations with independent human spaceflight capabilities, demonstrating its technological prowess and boosting national pride.
  •  Spur further advancements in space technology, leading to the development of new space-based applications and services.
  •  Ignite the imagination of young minds and inspire future generations to pursue careers in science, technology, engineering, and mathematics (STEM).

4. Indian Space Research Organisation

The Indian Space Research Organisation (ISRO) is the premier national space agency of India, headquartered in Bengaluru. Established in 1969, ISRO has emerged as a global leader in space technology and is renowned for its cost-effective and innovative approach to space exploration.
