South Korean space start-up Innospace has introduced a new suborbital rocket, “Sebit”, as part of plans to broaden its launch service portfolio beyond satellite deployment into testing and research applications. The company said the vehicle is designed as a multipurpose platform capable of supporting a range of missions, including microgravity experiments, component validation and high-altitude technology testing. The rocket is powered by a three-tonne-class hybrid engine and is designed to reach altitudes of more than 50 kilometres.

Innospace stated that the addition of Sebit extends its existing launch vehicle portfolio, which includes the “Hanbit” series developed for small satellite launches and earlier hybrid rocket programmes. The new system is intended to support demand for testing and verification services in addition to launch services.

A first flight test is scheduled for July at the Alcantara Space Center in Brazil, where the company plans to assess performance and operational stability ahead of commercial deployment. During flight, the rocket will transmit real-time telemetry data to ground systems to monitor performance. The company said the development reflects growing demand for high-speed and high-altitude testing environments across both commercial space and defence-related applications. 

Separately, Innospace said it is continuing work on follow-up launches of its Hanbit-Nano vehicle after investigating the cause of an earlier mission termination in cooperation with Brazilian aviation authorities, with a subsequent launch planned for later in 2026 subject to regulatory approval.
