Trump just continually shooting our country in the face. This unwarranted (and likely illegal) destruction of Goddard is madness. It jeopardizes the next several decades of space exploration.
Reposting to correct an error: trump admin is quietly gutting 13 buildings and about 100 laboratories at Goddard campus that has been instrumental to Hubble and James Webb telescope missions. Staff say they’ve be locked and told to move equipment. Anything left behind will be thrown away.
NASA may be quietly gutting an iconic campus with what it calls strategic closures, workers fear
(CNN) — Alarm is growing among federal workers at NASA’s iconic Goddard Space Flight Center’s main campus in Greenbelt, Maryland — the nerve center for groundbreaking missions like the Hubble

Layoff notices at JPL are going out today.
About 11% of the Lab, or 550 people, are being let go.
I'm thinking of my friends and colleagues there, some of whom will still be employed after today and some of whom won't.
I'm sorry you're having to deal with this.

Just a reminder that NWS is considered essential during a government shutdown. Meteorologists will still go to work, forecasts will still be made, watches and warnings will be issued, data will flow. We won’t be paid until the shutdown ends, but we’ll still protect life and property as always.

I recognize that significant impacts from #Imelda are still possible without a direct landfall, but it's curious that the @accuweather.com track makes landfall while the NHC forecast keeps the storm offshore.
