Europa Clipper observes…. Mars? Yes, on its cruise to the Jupiter system, Europa Clipper swung by Mars for a gravity assist and captured this cool image of Mars and its two tiny moons.

Four charts showing the extent of cuts to NASA in the FY26 budget:

- Cuts to every science division
- Smallest science funding since 1984
- 19 active, inflight missions cancelled
- Smallest NASA budget since FY 1961

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.

Next stop for Europa Clipper: Mars??? That’s right, we are doing a rare Mars gravity assist on March 1st to help pick up speed on our journey out to the Jupiter system. More info and cool animations below!

Ganymede's cool and all but Europa has a giant ocean of liquid water - more water than all Earth's oceans combined - close enough to the surface to interact with it, great chemistry at the icy surface from radiation, and even more chemistry at the rock layer at the bottom of the ocean.

Want one of those amazing rainbow NASA pins you've seen the cool kids wearing? Here's your chance! Contribute to help get pins made for distribution at conferences, or to get your own bag of pins (choose which design) to distribute as you wish.
