A compilation of SpaceForest SF-1000 rocket engine tests recorded over several months in Poland.

Based in Poland, SpaceForest is developing a new commercial single-stage European sounding rocket offering almost four minutes of microgravity experimentation time and uses the SF-1000 engine.

The SF-1000 runs on nitrous oxide and modified paraffin, commonly used as candle wax, and so its propellant is non-toxic. It ran during one of these tests with a total impulse of 1200 kN and a specific impulse – and indication of engine efficiency –  of 212 seconds. At one point the video greys out, this is due to the camera recording the engine overheating.

The last test in this video shows the engine using a thrust vector control actuator that provides directional control on ascent.

The Perun launch service offers commercial and institutional customers access to microgravity to run experiments. 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. The service is geared to provide easy access to payloads right up to an hour before launch, which is useful for last-minute tweaks, preparing biological samples or charging batteries for example.

To support the further service development and deployment of Perun, ESA is offering co-funding of through its ‘Boost!’ programme, boosting commercial initiatives that offer transportation services to space, in space, and returning from space. The programme also supports Member States implementing national objectives for spaceports, testing facilities and more.
