We make fusion engines for spaceships



HelicitySpace develops critical propulsion and power technology necessary for enabling humanity's expansion into the solar system.



Fusion space propulsion

A reality before terrestrial fusion power plants

A direct fusion drive produces high specific impulse and high specific power, enabling rapid transportation of heavy payloads anytime, anywhere in the solar system–and beyond.

By focusing primarily on generating thrust from repetitive short pulses, we can make fusion space propulsion a reality before fusion power plants.





Helicity Drive

Efficient, scalable, compact

Based on rigorous science and modern technologies, our unique technology is innovative, compact, and realistic.

Our fusion concept merges several plasma plectonemes in a constant-energy compression magnetic nozzle. We exploit the efficiency of magnetic reconnection for heating, the stability of plectonemes for confinement, and the symmetry of passive coils for magnetic compression.


Our innovative approach can operate at modest fusion gains and scale to ignited operation. 

The engineering requirements to achieve fusion conditions are significantly simplified.





About us

An international, interdisciplinary team



We are an international team of physicists, engineers, and entrepreneurs passionate about fusion energy and human space travel.

After decades accumulating world-class expertise in some of the world's most eminent universities, fusion laboratories, aerospace companies, and financial institutions, we founded HelicitySpace in 2018 to tackle one of humankind's greatest adventures with one of humankind's hardest technical challenges.


Leaving the cradle to protect the cradle

Humanity is expanding into the solar system.

New worlds. New resources. New opportunities. 


Earth is a protected World Heritage Site.

Our mission is to enable space colonization with fusion technology.
