The Japanese Nippon Yusen Kaisha (NYK) has obtained approval from ClassNK for the design of an offshore reusable rocket recovery system.
The initiative, developed through the Japan Aerospace Exploration Agency (JAXA)’s Space Strategy Fund, will enable NYK to conduct a demonstration test in 2028, collaborating with various partners, including Mitsubishi Heavy Industries.
But how does this recovery system work?
Rockets are launched by generating thrust through fuel combustion. After launch, the lower stage (first stage) of the rocket separates from the upper stage and falls back to Earth.
The offshore recovery system consists of two vessels: a recovery ship, where the rocket’s first stage lands, and a command ship that supports recovery operations. The recovery ship remains stationary at the landing site, serving as the landing point for the falling rocket’s first stage. The recovery ship is equipped with a dynamic positioning system (DPS), allowing it to maintain its position precisely, accounting for factors such as tidal currents. Notably, the recovery ship will operate entirely unmanned during rocket recovery, and the rocket will be securely fastened after landing on the recovery ship. Once the rocket has landed, the command ship will coordinate with the recovery ship to safely return the rocket to port.
For NYK, this is a business with enormous potential.
“With the increase in the number of rocket launches, a corresponding rise in the demand for transporting rocket components and satellites is expected,” states the shipping company in a press release. “We aim to leverage our strengths as a comprehensive logistics provider to seize business opportunities related to space development,” it adds, highlighting how advances in the development of recovery ships now enable the reuse of rocket first stages, increasing the frequency of spacecraft launches.
