It’s easy to think about satellites as a bunch of mini-moons, orbiting the Earth seamlessly and without any (noticeable) movement. But that’s not quite right: satellites and other spacecraft often require fairly continuous tweaks to their positions in orbit.
Historically, the aerospace industry has relied on thrusters, or a combination of reaction wheels and magnetic torque rods, to control a spacecraft’s attitude, control and positioning. But these take up a lot of space and mass, and limit how long a spacecraft can stay in orbit. New Zealand-based Zenno Astronautics has come up with an alternative to these heavy and time-limited propulsion systems. The core technology is an electromagnet that generates a very strong magnetic field, which can interact with other magnetic fields — like those on other spacecraft, or even Earth’s own — to generate torque.
The technology caught the interest of investors, who recently contributed to a NZ$10.5 million ($6.585 million) seed round. New Zealand-based VC firms GD1 (Global From Day One) and Nuance Connected Capital led the round, with additional participation from Shasta Ventures, NZGCP, K1W1, Austrian billionaire Wolfgang Leitner, Alt Ventures, Enterprise Angels, Arkisys and NZVC.
The funding marks the beginning of what Zenno hopes will be a landmark 18 months, culminating in their first launch in the fourth quarter of 2023. Around the same time, the company hopes to have a production facility operating with a massive manufacturing capacity of 1,000 electromagnetic systems per year.
“We can generate a new type of force in space,” founder Max Arshavsky told TechCrunch. “That is really the most fundamental breakthrough that we have.”
