We all have to speak up to prevent this from happening! Here is why NASA science is important to me:
"NASA science programs uniquely expand our knowledge of our home planet and the universe around us. This gives me perspective on my world and inspires me to be the best person I can be."
BREAKING: The president's budget request just hit Congress, which could usher in a dark age for NASA space science.
Congress has the final say, but you can help shape the outcome by adding your name to our global petition.
This is just the start of our fight.

We need to contact our Congressional representatives and Senators to urge them to restore funding to prevent this colossal loss of science and waste of money already spent!
The president's proposed 2026+ budget will eliminate or severely handicap many NASA astrophysics and planetary science missions. Ironically, a number of these have already been mostly built (e.g. $3+B spent on Roman), or are already operating (Keck, Euclid), or delivered to partners (Ariel/CASE).
Here's NASA astrophysics, if I read the president's proposed budget correctly. 🔭
