“Researchers say the satellites themselves are operating normally and do not appear to have suffered any errors that would physically prevent the data from continuing to be collected and distributed, so the abrupt data halt might have been an intentional decision.”

Wait, the U.S. aren’t even going to try selling the satellites? We’re just scrapping them?

That claim does not seem justified.

> 2016 failure of DMSP 19 without replacement[edit] On 11 February 2016, a power failure left both the command-and-control subsystem and its backup without the ability to reach the satellite's processor, according to the U.S. Air Force Space Command investigation released in July 2016 that also announced that DMSP 5D-3/F19 was considered to be 'lost'. The satellite's data can still be used, until it ceases pointing the sensors towards the Earth. The satellite was the most recent on-orbit, having been launched on 3 April 2014.[15]

> The failure only left F16, F17 and F18 – all significantly past their expected 3–5 year lifespan – operational. F19's planned replacement was not carried out because Congress ordered the destruction of the already constructed F20 probe to save money by not having to pay its storage costs. It is unlikely that a new DMSP satellite would be launched before 2023; by then the three remaining satellites should no longer be operational.[16]

To anyone acting as if this is a surprise or they're suddenly caught out and have to switch to another provider, I have to wonder, with the writing on the wall for 8 years now, how have you not already updated your plans?

That's the guardian for you. Remove context. Generate hyperbole. Beg for money.

That doesn't accurately capture the reason why there's outrage here. In the weather community, we're constantly thinking through contingencies because a great deal of things are out of our control - and we rely on aging infrastructure, much of which is already flaky to begin with.

Data outages and data loss happens. But there's no reason to allow a _preventable_ data loss to occur. The DMSP data is still being collected, it's just not being distributed downstream. And the decision to make this policy change was seemingly done rapidly and with no input or feedback from the user community of this data - both inside and outside the federal government.

There's no reason to turn off the spigot of this data. And there certainly is no reason to do so abruptly and with virtually no notice. As a consequence, the community is limited in its ability to adapt. For instance, it would take time (and money) to spin up more hurricane hunting resources to replace the overpass data that the SSMI/S instrument captures. Some private companies operate PMW satellite constellations and we could accelerate the acquisition of these data, but there are limited (read: none) federal mechanisms to do this and due to vertical integration in the weather industry, the operators of these constellations may not actually be inclined to do so - and certainly won't do so on the cheap, especially for the federal government.

So this isn't hyperbole. This is a really big deal. It might not be visible to you, but there is a panic and scramble occurring in the weather community to figure out what to do from here.

And for the record - yes, the same panic would happen if the DMSP satellites failed suddenly due to natural causes. But this current situation could've - and should've - been prevented.

That's the goal, actually. You can be sure someone in the admin owns stock of these companies and pushed for this policy for this very reason.

The companies I'm referring to are (generally) not publicly traded, so it's not quite that simple. Is it possible that some sort of backroom shenanigans are going on here? Yeah, absolutely, especially as several knowledgable folks speaking publicly about this episode are pointing their fingers at opaque procedure within Space Force.

But Hanlon's razor ought to apply until shown otherwise.

Stock doesn't have to be publicly traded to be traded.

You're right, but I would stress that this is an over-simplification of the entangled financial interests that _might_ be at play - and there simply isn't any evidence that has been presented pointing in that direction.
