Bengaluru Firm Protoplanet Enabled ISRO's High-Altitude Human Behavior Simulation in Ladakh
When the Indian Space Research Organisation (ISRO) and the Institute of Aerospace Medicine (IAM) concluded their high-altitude human behavior simulation near Leh on April 9, attention largely centered on the psychological insights gained for future space crews. However, a crucial yet less visible role was played by a Bengaluru-based firm that made the entire exercise possible on the ground.
Protoplanet's Critical Infrastructure for Mission MITRA
Protoplanet was entrusted with building and operating the comprehensive infrastructure for Mission MITRA (Mapping of Interoperable Traits and Response Assessment). This ambitious project examined how small teams function under conditions of isolation, confinement, and stress in a low-oxygen environment, closely mimicking the challenges of space missions.
The simulation site, situated at approximately 4,000 meters above sea level, provided conditions that approximate the physiological and operational hurdles astronauts face. Siddharth Pandey, director of Protoplanet, explained to TOI: "Within a short planning window, we identified and secured a site near Leh and set up the core facilities needed for the simulation. These included compact living modules designed to restrict movement and personal space, mirroring the constraints of a spacecraft or orbital station."
Replicating Space Mission Conditions
To authentically replicate mission scenarios, Protoplanet established a sophisticated multi-site layout. This consisted of two separate camps that could not directly see each other, overseen by a central mission control station. This configuration allowed ISRO teams to practice remote coordination, a vital skill for future planetary missions where crews may operate at a distance with limited real-time communication capabilities.
The firm facilitated operational tasks that extended beyond routine daily living. Participants engaged in simulated extra-vehicular activities and indoor procedures while contending with communication delays and environmental stressors, providing a realistic test of their adaptability and resilience.
Life Support and Instrumentation Systems
Supporting these activities was a robust basic life-support setup, which included solar-powered systems with backup provisions and comprehensive logistics to sustain teams for several days in sub-zero temperatures. Pandey detailed: "Crew members ate space-analogue food supplied by DRDO alongside freeze-dried rations, the same provisions used during the Project HOPE mission in September 2025."
Instrumentation formed another critical component of Protoplanet's support. The company deployed wearable devices and on-site sensors to continuously track health indicators and measure performance metrics. This included monitoring how participants handled tasks requiring precision and decision-making under strain, aiming to generate valuable data on both physical and cognitive responses to extreme conditions.
Safety and Broader Implications for Human Spaceflight
Given the challenging terrain, safety systems were meticulously integrated into the exercise design. Emergency response arrangements, evacuation plans, and coordination with local authorities and the armed forces were established before the simulation commenced, ensuring participant security throughout the study.
The Ladakh simulation is part of ISRO's broader strategy to prepare for human spaceflight missions, including the landmark Gaganyaan program. While ISRO leads the scientific objectives, exercises like Mission MITRA depend on precise field execution in difficult environments. This collaboration highlights how private firms like Protoplanet are increasingly utilized to handle operational layers—setting up controlled conditions on Earth so that spaceflight risks can be thoroughly studied and mitigated in advance.
With the April exercise successfully completed, the data collected is expected to significantly inform future crew training and mission planning. This is particularly relevant for long-duration and deep-space scenarios, where understanding and optimizing human behavior can be as critical as the reliability of hardware and technology.
