Electrical power, coolant, and communication lines were activated. Currently, JEM/SMILES is in the initial checkout phase.

Telemetry and command communication between in-orbit JEM/SMILES and on-ground Experiment Operations System (EOS), developed by Mitsubishi Space Software, is fine. Mechanical cooler has already started cooling. It will take about 3 days to achieve the lowest temperature of 4 Kelvin.
