Heki Mission
The Hēki Mission is an ambitious test of a superconducting magnet and power supply in space.
These are crucial components for the ground-based Kōkako thruster, an advanced propulsion system.
Kōkako thruster—A revolutionary propulsion system
The Kōkako thruster—named after the New Zealand native bird—is an electric propulsion system that exhausts plasma to generate thrust.
Two key components are central to this system:
- the plasma “rocket” creates and expels plasma to produce thrust
- the superconducting magnet accelerates the plasma to increase efficiency.
The superconducting magnet's unique property of having zero electrical resistance allows it to generate extremely strong magnetic fields with minimal power consumption—a significant advantage in space where power is limited.
The role of superconducting technology
Superconducting magnets are essential to the Kōkako thruster's efficiency. Unlike traditional magnets, these magnets can produce powerful magnetic fields without electrical resistance, making them ideal for space applications.
The Hēki Mission aims to validate the feasibility of using superconducting magnets in space by demonstrating their compatibility with other systems and successful operations in harsh environments just outside the International Space Station (ISS).
Hēki mission objectives
The Hēki technology demonstration payload, named after the te reo Māori word for egg, serves as a precursor to the Kōkako thruster. Hēki focuses on testing the superconducting magnet and its power supply, known as a flux pump, in the launch and space environment. These flux pumps are designed to generate high currents at very low power, which is essential for the magnet's operation.
Advantages of the Kōkako thruster
The Kōkako thruster offers several advantages over existing electric propulsion systems. It can operate with various propellants, enhancing its flexibility and cost-effectiveness.
Additionally, it can achieve higher power levels and thrust while maintaining efficiency, making it suitable for long-term missions to destinations like the Moon, Mars, and beyond.
