Chennai-based OrbitAID Aerospace is set to make history with India’s first in-orbit satellite refueling demonstration in late 2026, following a landmark partnership under the Indo-Australian Space MAITRI grant. The mission, supported by the Commonwealth, will deploy OrbitAID’s patent-pending Standard Interface for Docking and Refuelling Port (SIDRP)—a technology poised to revolutionize satellite operations by enabling refueling in space, extending mission lifespans, and reducing orbital debris.
Founded in 2021 by Sakthikumar R, Nikhil Balasubramanian, and Mano Balaji K, OrbitAID aims to establish itself as a leader in sustainable space logistics, positioning India at the forefront of the rapidly growing global space economy.
