Former GOES engineer here. At this point I'd almost be surprised if 19 didn't have something go wrong. We had issues on almost every other satellite. GOES-17 had the loop heat pipe anomaly(Supposedly from someone stepping on it in the cleanroom...), GOES-15 (IIRC) had a micrometeorite strike, and GOES-13 had a fuel tank anomaly right before deorbit. GOES-16 and GOES-17 are on-orbit spares, so in the extremely unlikel…

From now on, every time I see the word "anomaly" I will assume it is an euphemism for "someone stepped on it".

I love how "safe mode" for a satellite is basically: "extend solar panels, turn self towards sun, don't do anything unnecessary, wait for further instructions".

My restorative mode is also "turn self towards sun, don't do anything unnecessary".

How do they track that? Is there a log book where someone has to write to? "Observed EMP555 step on loop heat pipe. Conducted visual inspection of the affected area; no damage found, pipe remains nominal."

“Measurements taking of the person: foot and shoe weight, total weight including clothing, height and leg length, estimated velocity of travel at time, estimated duration of load”

The cool thing about geostationary orbits is that they're far enough out that they get 24/7 sun (Except around the equinoxes). We could easily fit a solar worship break in the schedule in between imaging and momentum dumps.

Earthian, I believe? If you adhere to the same rules as Martian, Venusian, et al. I’d me more inclined to use Earthen, capitalized, though.

From the latest update (https://www.ospo.noaa.gov/operations/goes/status.html#datafi...), it looks like they're already restoring systems.

``` Update #3: DCS and SAR have returned to service as of 1630Z. Engineers will now work to restore ABI and expect imaging to resume by 1900Z. Image navigation may be slightly degraded for the first hour after imaging starts. The GOES-19 instruments will be restored in the following order:

    ABI
    GLM
    SUVI
    CCOR-1/EXIS/MAG/SEISS
The recovery process to return all GOES-19 instruments to normal operations is projected to take approximately 8 hours.

Update #2: The GOES-19 Safehold has been resolved and engineers are working to prepare for restart of the onboard instruments. More information on the recovery timeline will be provided when known. ```

As an aside, I'm always surprised how US Gov websites look like they've been made in Dreamweaver in about 2006. Not even seemingly with a emphasis on usability either.

Lots of the web still looks like this when you step outside the comfort zone of big tech search engines, content streaming sites, and social media.

Looks like its started to publish new imagery again! I'm sure those fellows are relieved to have it working... I can't imagine the stress of trying to debug something that far away and unreachable!

Was this reported anywhere in the news? Sounds like one of those "not even once" kind of mistakes.

Why must everything look and be modern

The counter to this is the UK.Gov website. Very simple and basic, modern (maybe) but very accessible. Government websites should put accessibility over everything else.
