This doesn't sound particularly good

First, just read the headline:

IG: NOAA, NASA Launched Next-Gen Satellite With Known Issues, Scrubbed Performance Metrics from Contract

So, basically, there were problems with the prime instruments (the Advanced Baseline Imager, ABI) on the satellite before launch.  Apparently NASA and NOAA changed the contracts so that this wouldn't affect the payment to the contractors despite knowing about the deficiencies.  And then they launched the instruments with the deficiencies.

Not good.

Let's summarize with three excerpts:

1.Testing on the ABI in March 2017 prior to launch showed issues with the cooling system. Engineers devised a workaround but only tested the changes at “ambient temperatures and pressures,” according to the IG, which did not simulate the conditions in which the satellite would be operating in space.

With the modifications tested at ground level, the risk management team labeled the issue as fixed and “did not categorize the thermal anomaly as a failure,” the IG wrote.

2.The ABI cooling system subsequently failed in April 2018, shortly after the satellite launched in March.

This should not be a surprise to anyone.

3.Engineers have since been able to get the GOES-17 satellite to deliver 97% of the data it was designed to, though it will never be able to operate at the level intended.

You can read the rest.  NASA may have "space" in its name, but this was not stellar performance.
