Gaganyaan: ISRO conducts simulation missions

Key Highlights:

• ISRO is conducting Gyanex, simulation missions for the Gaganyaan program, to prepare astronauts for space-like conditions.
• These analog experiments involve astronauts spending several days in confined spacecraft-like conditions to simulate a human space mission.
• The primary goal is to develop protocols for communication and resource management in the absence of gravity.
• Gyanex-1, the first in the series, was conducted in July, with Group Captain Angad Pratap and two others confined for 10 days.
• During Gyanex-1, the crew members conducted 11 science experiments, and parameters were recorded to guide protocol development.
• The first human spaceflight mission under Gaganyaan is scheduled for 2027.

Detailed Insights:

• Gyanex missions aim to replicate all aspects of a space mission except microgravity, which is difficult to simulate on Earth.
• Astronauts live in a confined crew module and space station, following routines and conducting scientific experiments with limited resources.
• Food consumed during these experiments is developed by DRDO, ensuring astronauts are accustomed to space-specific provisions.
• These experiments are conducted in a static mock-up simulator in Bangalore, providing a realistic spacecraft environment.
• The data collected from Gyanex missions will help refine protocols for future crewed missions, enhancing mission preparedness.
• A series of Gyanex experiments are planned before the actual human spaceflight mission to ensure comprehensive training and protocol validation.

Key Concepts Involved:

• Gaganyaan: India's human spaceflight program to send astronauts into Earth's orbit.
• Analog Experiment: Simulation missions on Earth that mimic the conditions and activities of a space mission.
• Microgravity: The condition of near weightlessness experienced in space due to freefall.
