Iran's Space Agency to Test Upgraded Bio-Capsule in Suborbital Launch

Iran (IMNA) - Hassan Salarieh, head of the Iranian Space Agency, stated that the new bio-capsule is set for an experimental launch in the coming year, aimed at conducting initial tests to demonstrate its technical capabilities. He highlighted that this follows the launch of a 500-kilogram bio-capsule two years ago, which prompted the development of the next-generation model. Originally designed to weigh approximately 1,500 kilograms, the project has been optimized to a final mass of about 700 kilograms after extensive technical studies and redesigns.

Despite the weigh ,reduction Salarieh emphasized that the updated capsule is significantly more advanced than its predecessors, particularly regarding volume, mass efficiency, and guidance, control, and navigation systems. A critical enhancement is the improved controllability and attitude control of the capsule, essential for future missions that may transport living organisms and potentially humans. He noted that precise landing capabilities are vital for bio-capsules.

The new capsule is designed to accommodate biological payloads under various conditions, with consideration for the possibility of carrying humans. However, Salarieh confirmed that no living organisms will be aboard during the initial launches, as multiple test missions are necessary to validate the capsule’s performance.

Regarding life-support systems, Salarieh explained that providing suitable biological conditions, including tolerance to acceleration and environmental factors, is a core design requirement. The capsule will be launched using a domestically developed liquid-fueled vehicle, necessitated by the new capsule's increased mass. The earlier model used the “Salman” launcher.

The new launcher is being developed with a focus on managing acceleration levels, as living organisms can only withstand limited g-forces. Salarieh noted that the design and construction of the launcher are progressing alongside the capsule’s development.

While setting an exact launch date is challenging due to potential technical delays, current estimates suggest an experimental launch could occur within six to nine months, likely in early 2026.
