65 million years ago a 100 million Megaton city-sized asteroid hit what is now Mexico. That impact led to the extinction of 70% of all species on Earth and the extinction of the ancient dinosaurs. Remember Chicxulub! Originally created for The Planetary Society’s 2018 Kick Asteroid Campaign. Comes in women relaxed or slim fit. You could consider the slim fits as stand-ins for women’s XXS, XS.

Celebrate the awe-inspiring spectacle of the 2024 Great American Total Eclipse with our exclusive T-shirt. This design captures the majestic beauty and drama of the eclipse, which promises to be particularly stunning given its alignment with the Sun at its 11-year maximum activity period. Commemorate this celestial event with the spirit of exploration championed by The Planetary Society.

The Planetary Society has a big bash lined up in Fredericksburg, Texas, this year called Eclipse-O-Rama, and we've been busy designing loads of Texas-themed swag for it. But we know the eclipse is a North American event, not just a Texas one. So, we didn't stop there – and went and created a national version to be sure nobody feels left out of the party.

Your Place in Space is our newest brand tee for the Planetary Society. We don’t want to say that’s Carl Sagan’s finger pointing at that pale blue dot, but who’s to say it’s not?

It is the evolution of space missions. From the tiny Sojourner to Spirit/Opportunity to Curiosity, eventually leading to the first humans on Mars. Planetary Society’s Advocacy group knows that every mission counts and is why they are fighting to get the most important missions the funding dollars they need to reach their goals.
