SpaceForest PERUN suborbital rocket – open call for research payloads and experiments 2026

Suborbital Rocket | Space Missions | Call for Payloads & Experiments

PERUN is the ideal choice for suborbital space flights. It is a single-stage, guided suborbital launch vehicle powered by a hybrid rocket engine, designed to deliver high performance at a low cost of operation.

The rocket enables experiments in a microgravity environment and provides access to near-space and spaceflight conditions, including high dynamic loads and vacuum exposure. PERUN supports controlled mission profiles, reliable payload recovery, and post-flight handling in cleanroom conditions, enabling both technology demonstration and scientific research missions.

ADVANTAGES

  • Controlled flight path
  • Trajectory accurate determination
  • Low accelerations
  • Controlled orientation during micro – G time
  • Simple preparations and transportation
  • Simple pre-launch operations
  • Late payload access – up to 1 h before flight

Payload Support

  • Payload qualification for flight – a comprehensive technical assessment ensuring compliance with suborbital flight requirements and the safety of your payload during launch, flight, and recovery.
  • R&D support for payload integration – assistance in designing, adapting, and integrating payloads into the PERUN rocket module, along with engineering guidance to maximize the chances of experiment success.
  • Safe, tested launch and recovery procedures – proven protocols before, during, and after flight to guarantee payload integrity.

PAYLOAD

SpaceForest offers different payload modules (PM) to accommodate different payload volumes. The PM will be provided to the customer to mount their payload and send it back to SpaceForest for integration before a flight. Payloads can be sent directly to SpaceForest to handle the mounting and integration as well.

COMMUNICATION

The autonomous tracking and data exchange system RASEL allows for reliable, long-distance communication with a rocket and continuous monitoring of the vehicle and payload parameters. The rocket position is continuously transmitted to the flight control center to ensure flight safety and quick recovery after landing. The communication system will also be used to download or upload data from the payload in real-time.

GUIDANCE SYSTEMS

In the Perun rocket, we use two cooperating systems to control the rocket. The Thrust Vector Control (TVC) is a mechatronic system that changes direction of thrust in the engine phase of flight. The CGT (Cold Gas Thruster) is a system of 8 nozzles located on the body of the rocket, which counteract rotation of the rocket during the engine phase of flight. Later, the CGT system provides high quality microgravity by stabilizing the payload section and ensuring no rotation.

TRANSPORTER ERECTOR LAUNCHER

Focusing our engineering efforts on reducing the launch costs we developed the TEL – Transporter Erector Launcher to offer mobility and availability to launch from various spaceports around the world.
