PSI Senior Scientist Jamie Molaro sewed this week's #SciArt, a fun and cute baby quilt with navy blue silk and purple/teal patterned cotton. The Moon was created using a Photoshop filter on a photo to blur and separate the light and dark regions for cutting.
Ancient asteroid impacts left clues hidden in Earth's rocks. ☄️
From microscopic crystals to massive layers of buried debris, PSI scientists are piecing together the history of these powerful collisions.

The biggest “land rush” of the 21st century is underway—but not on Earth. The U.S. and China are now clamoring to build moon bases at the lunar south pole. But the Moon’s riches reach well beyond there. A new report flags where else astronauts should go.

PSI scientists are working with NASA on the lunar surface science team to map this region of the Moon and identify the best landing sites for Artemis IV. Tour the area for yourself ⬇️
The next chapter of human lunar exploration will unfold near the Moon’s South Pole.
This interactive lets you tour the region where the Moon Base will take shape and explore its distinctive lighting, rugged terrain, and notable landmarks.

"The Gimli of Tolkien lore discovered a sprawling cave system which he described to his elven companion as, 'chamber after chamber, Legolas; hall opening out of hall, dome after dome, stair beyond stair.'"
Fingers crossed we don't run into any orcs on the Moon!
GIMLI will probe the Marius Hills Pit for a hidden lava tube that could shelter astronauts and reveal the Moon's volcanic past. vist.ly/5mr6y
