High-temperature superconducting (HTS) electromagnets have been identified as a key enabling technology for many new applications in space such radiation shielding, electric propulsion, and science instruments. Despite their potential benefits, to date there no public examples of HTS operating space. A consortium led by Paihau-Robinson Research Institute intends fly demonstration mission called Hēki the International Space Station (ISS) operation 2025.Hēki's primary magnet consists four...
The incredible current density and high magnetic field generation possible with high-temperature superconductors (HTS) have the potential to revolutionize energy generation, e.g. high-power generators, compact fusion devices.
