Description
India is making significant strides in space research, particularly in the field of microgravity studies. The Indian Space Research Organisation (ISRO) is preparing for the Axiom-4 mission to the International Space Station (ISS), slated for launch in May 2025. This mission will include Group Captain Shubhanshu Shukla, an Indian astronaut, and feature seven key microgravity experiments developed by Indian researchers.
Understanding Microgravity
Microgravity refers to an environment where gravitational forces are extremely weak—almost a million times less than the gravity on Earth. Often described as "weightlessness," this condition is typically found in orbit and allows scientists to conduct experiments that are otherwise impossible under Earth’s gravitational pull.
Importance Of Microgravity Research
Studying various processes under microgravity is essential across multiple domains, including human physiology, material science, and biotechnology. It enables researchers to make discoveries related to cell growth, tissue regeneration, and even food production—offering potential breakthroughs in medicine, agriculture, and space exploration.
ISRO’s Selected Microgravity Experiments
For the Axiom-4 mission, ISRO has chosen seven experimental projects, each focusing on a different aspect of microgravity research:
Radiation Effects on Edible Microalgae – Understanding how space radiation impacts algae used in food.
Seed Germination in Space – Studying how salad seeds sprout in low-gravity environments.
Cyanobacteria Growth Study – Comparing the proteomic and growth responses of cyanobacteria under varying nitrogen conditions.
Tardigrade Survival Analysis – Investigating the survival mechanisms of Paramacrobiotus species in space.
Human-Machine Interaction – Examining how humans operate electronic displays in microgravity.
Muscle Regeneration Study – Assessing how metabolic supplements influence muscle recovery in space conditions.
Food Crop Seed Evaluation – Analyzing growth and productivity of crop seeds in space-like environments.
Building India Microgravity Research Ecosystem
The Axiom-4 mission marks a pivotal moment in India’s space science journey. The insights gathered from these experiments are expected to strengthen India’s scientific community and promote further research in space-based applications. It also sets the stage for more Indian contributions to international space missions and the advancement of space health, agriculture, and biotechnology.
