Orbital mobility emerged as a pivotal topic within the space sector last year, highlighted by substantial investment from venture capitalists in startups focused on agile satellite technology. A notable player in this arena is UK-based Magdrive, which claims its innovative electric propulsion system for satellites outperforms existing solutions in terms of thrust and compact design.
In the realm of propulsion systems, spacecraft designers face multiple trade-offs. Traditional chemical systems provide high thrust but lack efficiency, while electric propulsion (EP) is known for its efficiency but not its power. Magdrive aims to bridge this gap with a system that utilises solid metal propellant to create high-energy plasma. According to co-founder and CEO Mark Stokes, this technology delivers high specific impulse and significantly enhanced thrust, while also reducing weight. This advancement allows spacecraft operators to opt for electric propulsion, facilitating a range of new missions without relying on heavier, pricier chemical thrusters.
Stokes envisions that improved propulsion capabilities could revolutionise satellite operations, enabling enhanced missions such as sustained rendezvous, satellite servicing, collision avoidance, and even unpredictable orbiting for defence and intelligence purposes. The concept of orbital mobility, labelled as “dynamic space operations” by U.S. Defence officials, has garnered significant interest, with Magdrive being selected as one of six startups for the Space Force’s Hyperspace Challenge accelerator last year.
Scalability is one of the standout features of Magdrive’s technology, with initial products—Rogue and the larger Warlock—capable of being configured in grids to amplify thrust or constructed in various sizes, including a “Super Magdrive” akin to a dishwasher. Founded in 2019 by Stokes and CTO Thomas Clayson, the team has grown to over 20 members and is preparing to demonstrate its first full-scale Rogue thrusters in orbit by June. The startup secured a $1.8 million seed funding round, followed by approximately $10 million in grants, and recently completed a new funding round totalling $10.5 million to support product development, research, hiring, and expansion into the U.S.
Magdrive perceives advanced propulsion as vital infrastructure for sustainable growth in the space industry. Both Rogue and Warlock are designed for reusability, using materials like aluminium and copper that could potentially be sourced from space, which would set them apart from competitors reliant on Earth-based fuel. Stokes explains, “We can use the materials that are already in space to fuel the Magdrive as its propellant,” contrasting it with traditional approaches which require constant fuel shipments from Earth.
The recent funding round was led by Switzerland’s Redalpine and included participation from several notable investors. Following its inaugural orbital demonstration this summer, Magdrive plans to test its Warlock system by 2026 and the Super Magdrive by 2027. Stokes emphasises that the future of space missions will focus less on speed or longevity and more on achieving extensive manoeuvrability within the operational lifespan of spacecraft, positioning Magdrive to play a crucial role in this transformative era.
