Group Captain Ajit Krishnan, an astronaut candidate from India, is spearheading an innovative research project that compares the user-friendliness of US and Russian spacecraft. This research, part of his M.Tech program at the Indian Institute of Science (IISc), Bengaluru, explores the manual control systems and design approaches of spacecraft from these two leading spacefaring nations. The study is set against the backdrop of evolving space missions and the increasing importance of user interface in spacecraft design.

Today's spacecraft, including the SpaceX Crew Dragon, Russia's Soyuz, Boeing's Starliner, and NASA's Artemis Orion, are capable of autonomous operations but also provide manual controls for the crew. These manual controls are crucial for handling emergencies, docking with space stations, and ensuring a safe return to Earth. Krishnan’s research aims to assess and compare these controls' efficiency and intuitiveness, focusing on the practical aspects of user interaction with spacecraft systems.

Insights from Testing US and Russian Spacecraft Interfaces

Krishnan, a former Indian Air Force fighter pilot, has utilized virtual reality (VR) to test the user interfaces of both American and Russian spacecraft. Alongside twelve test pilots from the Indian Air Force’s Aircraft Systems Testing Establishment (ASTE), Krishnan evaluated simulators of the spacecraft. The VR setup included a headset and a specialized glove designed to simulate the restricted hand movements experienced in a spaceflight suit.

The research findings highlight significant differences between the control systems of US and Russian spacecraft. According to Professor Biswas, the Russian Soyuz spacecraft, which employs a control stick similar to those used in fighter planes, was found to be more intuitive and user-friendly. The control stick provides a direct, tactile interface that many users, especially those with a background in aviation, find easier to manage. The Soyuz spacecraft’s bottom-view interface, where astronauts view the Earth from below, was also reported to be more accessible and straightforward for both experienced pilots and novices.

In contrast, the American spacecraft, such as the SpaceX Crew Dragon, utilizes a touchscreen control panel. While the touchscreen interface requires users to interact with a digital display, which can be less intuitive compared to physical controls, it has been noted to be more fuel-efficient. Professor Biswas explained that the control stick in the Soyuz spacecraft consumes more fuel due to continuous movement, whereas the touchscreen interface minimizes fuel consumption by allowing control only when necessary. This efficiency in the touchscreen method helps conserve fuel, which is a critical consideration in spacecraft design.

Implications for Future Spacecraft Design

While this research is not directly related to India's Gaganyaan program, the insights gained from comparing US and Russian spacecraft controls could have broader implications for future spacecraft and aircraft design projects. The customized software, VR headset with an eye tracker, and EEG tracker developed for this research could inform the design of astronaut-carrying spacecraft and even passenger aircraft.

The comparison between US and Russian spacecraft is not just a matter of user preference but also a step towards optimizing spacecraft design for both functionality and efficiency. By understanding how different control systems impact user experience and resource usage, engineers and designers can develop more effective and user-friendly spacecraft. This research also underscores the importance of considering both intuitive control systems and fuel efficiency in the design process.

As the space industry continues to advance, the integration of user-friendly interfaces and efficient systems will play a crucial role in the success of future missions. Krishnan’s research represents a valuable contribution to this ongoing evolution, providing insights that could shape the next generation of spacecraft.

In summary, the comparative study of US and Russian spacecraft conducted by Group Captain Ajit Krishnan offers significant insights into the user-friendliness and efficiency of different spacecraft control systems. The findings from this research could influence future spacecraft design, contributing to the development of more effective and intuitive systems for space missions.
