"Sit tight and assess" as used above is probably a reference to the movie "Don't Look Up" from a few years ago, which (heavy-handedly) parodied administrations like Trump I (and which unortunately seem much less like parody in the Trump II era).

Yes. Quoting Projct 225:

> Break Up NOAA ... NOAA consists of six main offices ... Together, these form a colossal operation that has become one of the main drivers of the climate change alarm industry and, as such, is harmful to future U.S. prosperity. This industry’s mission emphasis on prediction and management seems designed around the fatal conceit of planning for the unplannable. That is not to say NOAA is useless, but its current organization corrupts its useful functions. It should be broken up and downsized. NOAA today boasts that it is a provider of environmental information services, a provider of environmental stewardship services, and a leader in applied scientific research. Each of these functions could be provided commercially, likely at lower cost and higher quality.

https://envirodatagov.org/project-2025-national-oceanic-and-...

Tldr: shut down NOAA to suppress climate change evidence, research, and preparedness; outsource to private industry the remaining parts that are considered directly useful for commerce.

Is it any wonder that the CEO of Accuweather Barry Myers was a Trump donor who became a NOAA head administrator appointee in Trump's first term? The appointment fortunately failed. Now they're trying again.

No, it's an attempt to strangle NOAA's ability to forecast weather, so that anyone that needs to know the forecast for their livelihood (transportation, fisherman, anyone that is outside) are forced to pay a private corporation for that.

By what I'm sure is a random coincidence, the CEO of Accuweather donated to Trump's campaign.

Accuweather, who also depend on this same USG sensor data for their modeling…

I don’t think anybody wins from this.

Frost1x · 8h ago
Are there other countries with similar weather satellites? I imagine China or the EU likely have some of their own. I know the US has been pushing this for free so plenty of nations likely piggy back off the free data. But I imagine larger ones might want their own redundant services to some degree to avoid vulnerability.

If so, they might be benefiting, but that’s about it.

"Since its establishment in 2014, the Copernicus program has received consistent investment from ESA, making it the world’s largest and most advanced open data Earth Observation initiative for climate, disaster, and resource management."[0]

Data from the Copernicus program is available for any citizen or organization worldwide. So a lot of free data will still be accessible.

Take one quick look at any wealth inequality graph over time and "who's winning" will be pretty clear. Someone always wins. This is simply a step at privatizing everything. Straight out of project 2025.

SpaceX?
defrost · 7h ago
Business as usual there,

SpaceX scores $81.6 million Space Force contract to launch weather satellite

  The contract for the mission designated USSF-178 was awarded on June 27  ( 2025 ) by the Space Systems Command and represents SpaceX’s third consecutive win under the National Security Space Launch (NSSL) Phase 3 Lane 1 program.

  The mission will carry the Weather System Follow-on – Microwave Space Vehicle 2 (WSF-M2), along with a secondary payload of experimental small satellites called BLAZE-2. 
~ https://spacenews.com/spacex-scores-81-6-million-space-force...

New weather sats going up, just not "free data for taxpayers".

dzhiurgis · 7h ago
This sounds so cheap that we could have thousands of individuals launch their private constellations.

Do you really need to subsidise this anymore?

If anything brining competition to this space (pun intended) might improve the data quality.

defrost · 4h ago
A contract to lift a sat to orbit improves data quality as much as a transport contract to deliver furniture improves a chaise lounge.

Satellites are still tricky and time consuming to build and are an entire other ball of wax than a lift to orbit.

dzhiurgis · 3h ago
Of course I'm not arguing sats are easy or simple or whatever, but overall cost has and still is dominated by launch cost, by at least an order of magnitude.
defrost · 3h ago

  A typical weather satellite carries a price tag of $290 million; a spy satellite might cost an additional $100 million
~ https://science.howstuffworks.com/satellite10.htm

  The National Oceanic and Atmospheric Administration (NOAA) asked the aerospace and defense giant to build it at least three, and potentially as many as seven, new next-generation Geostationary Extended Observations (GeoXO) sats. If all options are exercised, the total contract value will reach $2.3 billion.

  Bad news for Lockheed Martin: That works out to $324.3 million per satellite.
~ https://www.fool.com/investing/2024/06/30/lockheed-martin-wi...

It's generally agreed that ~ $90 million for a sat launch is less than a third of a ~$300 million per sat build cost.

Such as the Lockheed Martin 2024 contract I linked?

Sure.. try that link, it's from last year and talks about grown up big boy weather sat costs in 2024..

Your $30m SmallSat is not in the same league as a full featured $300m sat .. I'll leave you to work out the differences.

I had a bit of a chat with chatgpt and I agree the smallsats are not replacement just yet, but in future there's no doubt they are better in most ways - faster iteration, far better resolution and of course lower cost.

Here is what will be denied to NOAA, now and going forward

    Defense Department data also allow hurricane forecasters to see
    hurricanes as they form, and monitor them in real-time.

    For example, hurricane experts can see where the center of a 
    newly formed storm is, which allows them to figure out as 
    early as possible what direction it is likely to go, and whether
    the storm might hit land. That's important for people in harm's way,
    who need as much time as possible to decide whether to evacuate,
    and to prepare their homes for wind and water.
The public paid for this data. Deliberately siloing the data to insure it can't save American lives wouldn't just be theft, it would be an act indistinguishable from evil.
whycombagator · 7h ago
> NOAA, which oversees the National Hurricane Center, says the loss of the Defense Department data will not lead to less-accurate hurricane forecasts this year. In a statement, NOAA communications director Kim Doster said, "NOAA's data sources are fully capable of providing a complete suite of cutting-edge data and models that ensure the gold-standard weather forecasting the American people deserve."

> it would be ...

lots of ways to fill in that part. iterating the words seems worth the effort. Thinking out loud, there are readers with frame of reference, and movements or politics-in-practice that have frames of reference, in the messaging .. So making a 2x2 square and filling it in.. you can write for the readers and refine, you can align with movements or their spokespersons and refine, all combined with you yourself representing what you are about.

So to complete the exercise.. how many readers of YNews would respond to "that is evil" wording.. how many movements or politics-in-practice would say "that is evil" as part of their outfacing communications.. and how strongly to you, the writer, want to associate the concepts of "that is evil" with respect to other things that you say or think are important.

I write this pedantic screed because this is so, so critical to communicate right now. The narrow rocky valley pass in which to lay an ambush, is completely in place.. the budget strings. Everyone knows that this is raw executive power in action.. it is to be, because I say so, implemented via the purse. I am not sure how much to include those backdrop statements in any impactful messaging though, because "there is no bad news in sales" and popularity or adaption is part of the task.

Is that possible? I thought GPS works by just listening for signals from GPS satellites?

I’m now realizing I know hardly anything about GPS. Like it was made in the 50’s or something? Do we keep sending more GPS satellites into space? Or are there just the original handful?

hypercube33 · 4h ago
The basics of it are it's a digital synchronized time signal sent out by a constellation of satellites. Devices listen for at least 3 separate streams of time signals and the. triangulation happens to get a position.

Irrc the satellite signals not encrypted or whatever were randomized to be inaccurate on purpose. This is mitigated these days by using stuff like cell towers - we know exactly where they are. they pick the same signals out and send out corrections to the randomized data which increases accuracy.

Late 80s, early 90s for civilian use.

There have been several iterations of satellites and systems.

defrost · 2h ago
Late 70s:

  In February 1978, the first Block I developmental Navstar/GPS satellite launched, with three more Navstar satellites launched by the end of 1978.
esseph · 2h ago
We're coming at this from different angles.

Probably easiest for the OP just read the Wikipedia article.

defrost · 2h ago
Not sure about yourself, I'm coming at it from the angle of the dates the local (Nor'West Australia) ham operators started picking GPS signals from navigation satellites .. that and recording transmissions from the Harold Holt submarine communications base passed the time.

There were off book non US reverse engineered Navstar recievers cobbled together on benches in the mid 80s being trialed as alternatives to LORAN use.

That's a little earlier than your statement of "late 80s".

It'd be documented in, say, Geoscience Australia metadata notes to air surveys of the era.

Of course that'd be a primary source and not wikipedia, nor a wikipedia secondary reference newspaper article.

esseph · 1h ago
Early Block I was mostly used for testing.

If you're just concerned with the first satellite launch, ehhhh, sure. As a useable global system it was much later.

"The GPS project was launched in the United States in 1973 to overcome the limitations of previous navigation systems,[15] combining ideas from several predecessors, including classified engineering design studies from the 1960s. The U.S. Department of Defense developed the system, which originally used 24 satellites, for use by the United States military, and became fully operational in 1993. Civilian use was allowed from the 1980s. "

Here's the current list, marked by launch date and Block:

The GPS signal can be encrypted such that only the army can access it. The not encrypted signal can be made less accurate or disabled over specific regions.
XorNot · 6h ago
Which would be hilarious because one of the primary reasons GPS became generally accessible was because consumer GPS being accurate made it easier and cheaper to stick GPS in absolutely everything the military uses.

Basically trying to deny accurate positioning tends to not help your own forces as much as it being trivial for them to call back to your giant logistics machine with accurate positioning.

They're not just petty, they're wildly impractical.

You can't privatise NOAA and the services it offers. It cannot work at an equivalent level as a private service. Its effectiveness relies on being able to decide what's valuable in purely scientific terms, and those terms don't align with short-term corporate greed.

But if you ask these cranks what NOAA actually does, they'll have no clue. They're not just evil, they're stupid - the smallest, most banal bureaucrats, cosplaying radicals.

Yes the conflation is my bad because I think this move is relative to NWS privatization, which is what might strike most people. You can’t have the government predicting and tracking major weather events and issues, those are the biggest datasets to sell access too.

For other NOAA fallout effects in the government, a Potus wouldn’t have to rob from the FEMA funds if there’s nothing for FEMA to prepare for, in that FEMA cannot say we need to spend money to help flooding in Texas or hurricane damage in Florida.

“We shouldn’t keep trusting nation-states for meteorology data. They can and will cut off access if the powers that be demand it, even if it hurts billions of others by doing so.” - Me, circa mid-2010s

“You’re overreacting, nobody would be dumb enough to cut off access to data like that. Stop being alarmist.” - Everyone I have shared that thought with since.

Unfortunately, “I Told You So’s” don’t pay my rent, otherwise I’d have a decent home of my own by now. Here’s hoping ESA or JAXA help fill that gap until the UN can take over (an organization ideally suited for global meteorology tasks).

Michael Lewis, in the Fifth Risk, has a whole chapter on how during Trump 1 the head of Accuweather was basically trying to shut down free distribution of weather updates from NOAA/National Weather Service.

My hunch is that the location of the satellites can be deduced from the weather data. These satellites would be a target in a time of war.
gpm · 6h ago
The location of the satellites is public knowledge. Satellites are trivially tracked from the ground - the amateur community does this whenever someone tries to keep the location of one secret: https://www.popsci.com/zuma-spy-satellite-amateur-astronomer...

They also don't exactly move much, it takes precious fuel to change a satellites orbit.

3-5105 · 7h ago
Satellites using sun-synchronous orbits can circle the Earth multiple times in a day.Compared with a stationary observer on the ground,they are moving at a relatively fast speed.Therefore,as long as they delay the release of observational data by a random time period,there won't be this issue.Only geostationary satellites would have this problem.

But a bigger problem comes before the above issue:most of the current human meteorological satellites do not have stealth capabilities.You can see them directly.Perhaps your idea will become a practical problem when satellite stealth technology matures.

This is a translation.

skiboyec · 7h ago
I did not see your comment before I left mine! But yes the second half makes sense.

I do think you might able to deduce the orbit even if the data release is delayed by a random time period. If you’re a foreign adversary that has its own satellites, you can measure the same information from a known orbit. Then one could compare the published data with one’s known dataset to deduce things like the angle from which the data was measured.

Most plausible reason. National security hawks have always been extremely protective of intelligence even when the risk is tiny. Probably some DoD people (or person) wanted to keep it closed and new hawkish leadership let them do it.

Who knows, the Navy hasn't released any statement beyond "cyber security risks" so there's only politics to fill in the blanks.

It seems to be this agency https://en.wikipedia.org/wiki/Fleet_Numerical_Meteorology_an...

So why does The King get to tweet pictures from our spy satellites then?

Hmm I think I’m wrong. From what I can tell satellites , especially those in LEO can be optically tracked pretty easily

Yeah I was going to say: you can also know where satellites are by looking at them. Obviously we're not publishing weather data from the ones with important natsec equipment onboard.
