Based in Poland, SpaceForest is developing a new commercial single-stage European sounding rocket offering almost four minutes of microgravity experimentation time. The 11.5-m tall rocket will be able to launch 50 kg up to 150 km in altitude while also stabilising the payload for high-quality microgravity periods of flight.

Perun runs on modified paraffin, commonly used as candle wax, and so its propellant is non-toxic. The rocket can be launched on a mobile launch pad, allowing for easy deployment at launch facilities around Europe.

Last year, SpaceForest launched two full-scale models of its Perun rocket that flew to 22 km and 13 km altitude from the coastal town of Ustka, Poland, on the Baltic Sea.
