The University of KwaZulu-Natal’s Aerospace Systems Research Institute (ASRI) has set a goal to launch a South African satellite into orbit on a locally built rocket by 2030, preceded by a suborbital space flight targeted for 2028. Achieving these milestones depends on securing significant financial backing and rapidly expanding human capital. ASRI estimates that developing its planned two-stage Commercial Launch Vehicle (CLV) will require roughly R3 billion ($186 million), a stark contrast to its current R100 million two-year allocation from the Department of Science, Technology and Innovation (DSTI).

Additionally, the core engineering team must scale sixfold from roughly 20 personnel to at least 120. Recognizing that a university environment cannot easily absorb this level of operational growth, ASRI leadership is working with UKZN and government structures to commercialize its activities into a standalone entity.
ASRI’s commercial transition is already underway. The institute signed an exclusive agreement with local firm Mura Space to commercialize the sounding rocket launch facility at the Denel Overberg Test Range near Arniston. Early-stage discussions are also taking place regarding a potential rocket assembly facility near Cape Winelands Airport. Infrastructure development reached a major milestone with the commissioning of a permanent, six-storey-tall launch gantry at Overberg, built in partnership with local firm TF Design.
The institute’s flight heritage relies heavily on its Phoenix hybrid rocket series, which has completed eight flights across five campaigns. Phoenix achieved an African hybrid altitude record of 17.9 kilometres in 2021. Subsequent flights conducted in late 2024 focused on payload data recovery and validating the new launch gantry rather than maximum altitude. Beyond its role as a technological demonstrator, the inertly fuelled Phoenix series serves as an essential training tool to build local rocket engineering skills that currently do not exist in the South African job market.
ASRI’s ultimate objective is a two-stage CLV engineered to deliver a 200kg payload into a 500km sun-synchronous orbit from the Overberg site. Structurally and operationally similar to Rocket Lab’s Electron vehicle, the rocket utilizes a nine-plus-one engine configuration burning liquid oxygen and kerosene via electric pumps.

Powering this vehicle is the Saffire (South African First Integrated Rocket Engine), a liquid-fuelled motor designed for 27.6kN of thrust. ASRI has already hot-fired an 18kN pressure-fed demonstrator named Able. Current development is progressing toward full-scale electro-pump testing and the assembly of a 3D-printed, regeneratively cooled combustion chamber. To manage development costs, ASRI plans to use its 2028 suborbital rocket to validate flight termination, telemetry, and recovery systems before committing full resources to the larger orbital CLV architecture.
ASRI collaborates closely with Stellenbosch University on turbopump development, control systems, and telemetry downlinks. This partnership aims to strengthen ties with the broader aerospace and satellite technology cluster in the Western Cape, which includes established private firms like CubeSpace, Dragonfly Aerospace, and Simera Sense.
While speculation has surfaced regarding international interest in the Overberg site—including unconfirmed reports regarding SpaceX—foreign integration faces complex regulatory and geopolitical hurdles. International launch technologies are subject to strict dual-use export controls, and foreign technology transfers can carry prohibitive costs while risking dependence on external entities. ASRI maintains that establishing a sovereign launch capability tailored to Overberg’s favourable southern latitude for polar and sun-synchronous orbits remains the most sustainable long-term strategy for South Africa’s space sector.
