European start-up The Exploration Company will work with ISRO on its debut mission in January 2024.
Originally planned with Ariane 6, the mission switched to ISRO's PSLV due to launch delays.
The mission will feature the "Bikini" prototype flying to Earth orbit and back in early 2024.
The Exploration Company's Nyx capsule aims to provide cost-effective, reusable cargo and human transport to space, with flexibility across launch vehicles.
