Mission managers for NOAA’s JPSS-2 confirm the satellite has acquired signal and is receiving and responding to commands. The satellite is currently power positive (getting electricity) and in a safe and stable configuration while teams assess the status of the solar array.
At this time, the team has not yet received data to confirm solar array deployment. There may not be an issue, but we’re monitoring closely as more telemetry data becomes available.
Following a planned hold, and using some of the 36 minute launch window to work an issue, teams are moving forward. As the team was filling the rocket with liquid oxygen earlier, they also were working a valve issue on the ground. There is about 28 minutes left in the window, and the new T-0 is 1:49 a.m. PST.
