Helicity Space develops in-space fusion propulsion and power technology, exemplified by its Helicity Drive, to enable advanced space exploration. Their proprietary system efficiently converts electricity into plasma heating, utilizing a novel magneto-inertial fusion method coupled with a peristaltic magnetic compression scheme. This compact, scalable, and reusable technology is engineered to generate thrust from fusion reactions, providing a more agile and efficient approach for deep space transit than current methods.
The company was co-founded by Dr. Setthivoine You, Marta Calvo, and Stephane Lintner, who collectively bring extensive expertise in plasma physics, operations, and strategic development. Dr. You, with over two decades in plasma physics and academic roles at The University of Tokyo and Caltech, spearheads technology. Marta Calvo, drawing on her background at Pratt Whitney Rocketdyne, manages operations, while Stephane Lintner, a Caltech PhD and former Goldman Sachs executive, guides strategic efforts.
Helicity Space's technology serves applications across human and robotic space exploration, national security, and expanding global commerce. The company's vision is to catalyze humanity's spacefaring future by enabling faster, more efficient deep space transports. This will facilitate critical advancements like off-world industries, interplanetary resource mining, and planetary preservation, ultimately ensuring sustained human presence across the solar system.

Helicity Space is a space technology company developing the Helicity Drive, a scalable fusion propulsion engine that enables safer, faster, reusable, and more fuel-efficient deep-space travel.[1][3][4][5] Founded in 2018 and headquartered in Pasadena, California (with early ties to Berkeley), it targets space exploration, science, off-world industries, and interplanetary resource mining by converting electricity into plasma heating for fusion conditions and direct thrust.[1][2][3] The company has raised $5M in Seed VC funding, including recent investment from Lockheed Martin Ventures, and holds patents in ion engines, nuclear spacecraft propulsion, and plasma physics.[1]
Helicity serves space agencies, commercial explorers, and national security entities, solving key limitations of chemical rockets: high propellant use, slow interplanetary speeds, prolonged radiation exposure, and rigid trajectories.[3][4] Its engines require no radioactive fuel, support 100 kW to GW power ranges, and fit current launch vehicles, driving growth through partnerships like DOE INFUSE and Limitless Space Institute.[1][4]
Helicity Space was co-founded in 2018 by Marta Calvo (Chief Operations Officer), Stephane Litner, and Dr. Setthivoine You in Pasadena, California, emerging from expertise in plasma physics and aerospace.[1] The idea stemmed from advancing magneto-inertial fusion via self-organized Taylor relaxation, magnetic reconnection, and peristaltic magnetic compression—techniques enabling compact, scalable plasma confinement and heating superior to traditional magnetic or laser fusion.[4]
Early traction included a $5M Seed VC round in December (latest: Seed VC - II), patents in core tech areas, and investment from Lockheed Martin Ventures, providing funding and collaboration access.[1] Supported by U.S. DOE’s INFUSE program, Limitless Space Institute, and affiliations like Fusion Industry Association, these milestones validated their propulsion focus amid rising commercial space demand.[1][4]
Helicity Space stands out in fusion propulsion through:
Compared to competitors like Frontier Aerospace (chemical thrusters) or Exos Aerospace (reusable launchers), Helicity's fusion focus offers higher energy density and deep-space agility.[1]
Helicity rides the commercial space boom, fueled by falling launch costs (e.g., SpaceX), rising interplanetary ambitions, and fusion energy breakthroughs enabling off-world economies.[1][3] Timing aligns with U.S. space priorities—national security, science, and resource mining—bolstered by DOE support and Lockheed partnerships amid geopolitical pushes for strategic advantages.[1][4]
Market forces like orbital synchronization limits and radiation risks from chemical propulsion create tailwinds; fusion unlocks agile, efficient missions for Mars, asteroids, and beyond, influencing ecosystems via tech transfer to Earth clean energy and scalable power for satellites.[3][4][6] As a seed-stage innovator, it accelerates humanity's solar system expansion, bridging startups and primes like Lockheed.
Helicity's path forward centers on prototyping Helicity Drive for near-term demos, leveraging Lockheed collaboration and DOE funding to achieve thrust bursts and scale to GW-class engines.[1][4] Trends like fusion commercialization, constellation designs (e.g., solar observation fleets), and Artemis/NASA deep-space goals will propel milestones, potentially enabling first fusion-propelled missions by late 2020s.[1][6]
Influence may evolve from propulsion pioneer to ecosystem enabler, powering reusable tugs, miners, and habitats—tying back to its mission of accelerating solar system access for survival and prosperity.[3] Risks include fusion scaling hurdles, but partnerships position it strongly in a $100B+ space economy.
