The Concept

The Solorocket is a Single Stage to Orbit (SSTO) rocket. The rocket has the ability to fly one passenger or a payload into space and allow rendez-vous with an orbiting space station.


The Solorocket was inspired by the Haaas 2CA by ARCA which is a Single Stage to Orbit craft. This improved SSTO launch system designed by ARCA provides a more reliable and safer launch protocol compared to staged rockets. We tried to imagine using it to launch a single astronaut into low earth orbit.

How It Works

The Solorocket features a cabin, approximately 1.5 m in diameter equipped for a single astronaut. The passenger sits on a straddle seat akin to the SkyRider 2.0, which is being developed by Aviointeriors. The seat would allow for a more comfortable journey compared to a classic upright seat which would feel cramped in the small cabin space. The use of a straddle seat would be ideal for the short ride to space and would provide more hand mobility.

The Solorocket is small and compact allowing for good fuel economy and a small jet door on the side of the craft will allow easy access into the cabin. It is envisioned that Solorocket will be powered with cutting edge rocket fuels to allow for maximum efficiency. This will also reduce travel time from earth to the international space station from 6 hours which is currently the time taken for the Soyuz rocket.

Space travel requires robust materials in order to cope with the pressures and temperatures faced during re-entry. One such challenge is the type of material used for the rocket body. The fuselage needs to provide adequate protection and prevent distortion and melting during the exit and re-entry in the earth’s atmosphere. The Solorocket could be used to develop and test new types of materials like carbon nanotubes to coat this spacecraft.

What Is It Used For?

The Solorocket will be used to transport a single passenger or a 220-pound payload into low earth orbit. The target cost would be 1M per launch. Imagine the Solorocket docking to an inflatable space hotel engineered by Bigelow Aerospace or any government-owned space station for that matter. Imagine launch complex able to send multiple rockets safely on an hourly basis. That’s the vision behind the Solorocket concept, inspired by Arca Space.


The Solorocket concept was imagined in November 2018 by Charles Bombardier and inspired by the development program of the Haas 2CA rocket . The concept was designed by Jorge Ciprian, an Industrial Designer from Argentina. Jorge graduated with a degree in design from the University of Buenos Aires, and he currently works as a freelance designer. Jorge also designed the Meritis Super yacht and the Katroli helicopter concept for Imaginactive.
