This story is NOT TRUE.

There is one operating satellite in this constellation, and congress voted to shut down the program in 2015.

The DMSP program was discontinued in 2015 by a vote in congress[1]. Virtually every working stallelite in this program has failed. As best as I can tell there's just a single working one specifically NOAA-19[2].

Instead the program has switched to JPSS[3] which is part of GEOSS[4].

The key facts are:

- DMSP satellites are up and measuring data - These data will continue to be measured after Monday - the government is discontinuing processing and public access to the data - This will impact our capacity to predict hurricanes and monitor sea ice.

Which of the above are “not true”?

While you're correct that Congress voted to phase out the program, you're wrong on a number of levels. First, NOAA-19 is not a DMSP satellite. Second, many of the DMSP satellites are still in orbit and functioning - even the very Wikipedia article you linked to shows this. There was no legitimate reason to cut off their data that we've been given. Third, JPSS and GEOS lack some of the capabilities of the DMSP, for example the Special Sensor Microwave Imager/Sounder that was still providing highly valuable real-time microwave data, including precipitation rates, sea surface wind speeds, sea ice coverage, water vapor levels and cloud properties.

So to be frank, the only thing that's "NOT TRUE" is nearly all of your post.

thank you!
