CALorimetric Electron Telescope (CALET)
Launch Date: August 19, 2015
Extended Mission Lifetime: 2024+ (Pending NASA and JAXA Review)
End of Operations: Limited by ISS lifetime, currently 2030
Data Archives: JAXA, NASA (HEASARC)
The CALorimetric Electron Telescope (CALET) is a mission on the International Space Station (ISS) studying cosmic rays, signatures for dark matter, and gamma-ray bursts. CALET was developed by JAXA with contributions from the Italian Space Agency and NASA.
| Instruments | Energy Range | Field of View |

Common GCN Circular Types:
| Type | Latency | Example |
|---|---|---|
| Observation of a GRB | 1 day | GRB 211115A |
| Follow-up of a GW trigger | hours | LIGO/Virgo S200115j |
Yearly Trigger Rates:
| Instrument | Type | Rates |
|---|---|---|
| CALET | GRBs, other transients, and non-astrophysical triggers | 140–150 |
Approximately half of CALET triggers will be of non-astrophysical origin.
