The Circulator was successfully restarted at 029/21:40:20 UTC, followed by the Compressor at 029/21:53:52 UTC. Our next transition to Compressor Operate will occur at approximately 030/01:02 UTC. Ops Request 18004 to ramp the NCC Compressor and transition to PID Operate was successfully completed at 030/01:09:14 UTC. Ops Request 18005 to dump the 8051 min/max and history buffer is in progress. The compressor commanded speed under PID control is continuing its gradual climb to a maximum of 7043 rps in surge, while our TBA inlet temperature is at 127.10 K and falling along with the rest of the cryogenic loop temperatures. |
