The star Polaris is a part of the constellation Ursa Minor, so housing the machine Polaris in the building Ursa makes sense. But Antares is the name of a star that is part of the constellation Scorpius. Why not name the manufacturing building Scorpius then to produce their commercial Antares-class m...

There was a Reuters article that provided an image with the following text appended: "Fusion energy startup Helion Energy's engineers test turbo pumps under ultra-high vacuum for th...
