| Abstract: | Abstract: The Balloon Facility of Tata Institute of Fundamental Research (TIFR-BF), an integral part of the Department of Atomic Energy (DAE), plays a pivotal role in advancing balloon-borne scientific research by providing a robust platform for experiments in astronomy, atmospheric sciences, and other disciplines. Over the years, scientific ballooning has evolved significantly, with advancements in materials, payload design, flight control, and propulsion systems, enabling more complex and high-precision missions. These developments have expanded the scope of high-altitude research and opened new possibilities for stratospheric exploration. One of the most notable shifts in recent years has been the renewed interest in using hydrogen as a lifting gas for stratospheric balloons. Historically, helium was the preferred choice due to its inert nature and safety profile. However, the rising global demand and limited availability of helium have led to sharp price increases, making it increasingly impractical for large-scale or long-term stratospheric missions. This has sparked global efforts to explore hydrogen as a viable alternative, given its abundance, low cost, and environmental sustainability. TIFR-BF has substantial experience in using hydrogen for balloon operations, having developed effective protocols for its safe storage, handling, and flight operations over several decades. The facility’s expertise ensures reliable and secure operations, mitigating the risks traditionally associated with hydrogen. This long-standing capability positions TIFR-BF to make meaningful contributions to the evolving global conversation about the feasibility of hydrogen-based ballooning. As the scientific community explores sustainable technologies for high-altitude missions, TIFR-BF's leadership will be instrumental in addressing key safety concerns and operational challenges. Leveraging its extensive experience, the facility is well-prepared to support future stratospheric balloon missions, paving the way for environmentally sustainable, cost-effective scientific research at the edge of space. |
