A single instrument in low Earth orbit, CALET, captured helium data across an expansive energy range, from 40 GeV to 250 TeV, for the first time, capitalizing on its remarkably wide dynamic range. The observed spectrum exhibits a deviation from a single power law greater than eight times, with a progressive hardening in the spectral energy range between a few hundred GeV and a few tens of TeV. This result is supported by the findings of both sp
