Our goal is to provide you or your business with a safe, reliable, affordable and reusable access to space.

This is a non-profit suborbital space endeavor lead by Sebastian Borg, Henrik Ågren and Per Lantz based entirely  on sponsors and volunteers. We believe in openness regarding both our successes and failures, and the progress updates here track our work from the beginning, enjoy!

SRRG is always looking for sponsors who would like to support our project, with either financial support or products. If you or your company is interested in sponsoring our project don`t hesitate to contact us.

On SRRG Facebook and Youtube site you can see videos, follow our daily updates and share ideas, enjoy!

High altitude test 

In mid-June we will carry out a high altitude test  with some of the electrical equipment which in future will  be installed in the rocket.
The equipment we will be testing is the GPS unit, Barometer, Video/data unit and altitude measuring unit. In this way we can gather important data, calibrate the sensors and avoid faulty measurements.
A 2.5 m wide weather balloon filled with helium will take the equipment up to a height of 10,000 feet ( 3048m ). 
Shortly after the barometer and altimeter senses the 10,000 m limit the quick release is triggered, releasing the load from the balloon and begins to fall back to the ground by parachute.

The test will take place between 10th - 24th June

Precise date coming soon...

Help us to move forward by supporting the project financially.

We have completed the:
- Parachute system ( interior )
- Separation electronics for fuel tanks , nosecone, cargo section.
- LES sequencing electronics and sensors. 
- Full-scale drawings of rocket  outer and interior design.
- Thermal control electronics ( Engine and heat shield )

Remains to be done:
- Cargo section (Framework)
- Engine mount 
- Rocket engine 

- Oxidiser tank: Stainless steel ( 2000*600*3 mm )
- Ethanol tank: Stainless steel ( 1800*600*3 mm )


RD-1 rocket engine 

Some measurements have been blurred for safety reasons.


Instead of spending a lot of money, not to mention time consuming it is to developing a new rocket engine, we have decided to go on an already proven and reliable such.

The RD-107 engine suits our objective. The RD-107 is a Attitude Control Engine for the Russian Soyuz rocket used in late 1970`s.It has a pulling force of 3,8 tonnes and it is powered on Ethanol (75%) and liquid oxygen (LOX).

The original engine was built with ordinary steel but we have chosen to build our in a more modern material such as stainless steel. It can withstand higher temperatures and it will not rust in contact with the fuel where ordinary steel would cause impurities and result in injector clogging or engine failure.
Our design has not changed anything compared to the original engine, the same dimensions, the same data. All we've changed is the choice of materials.
