5 Things to Know About NASA’s Tiny Twin Polar Satellites

This artist’s concept depicts one of two PREFIRE CubeSats in orbit around Earth. The NASA mission will measure the amount of far-infrared radiation the planet’s polar regions shed to space – information that’s key to understanding Earth’s energy balance. NASA/JPL-Caltech Called PREFIRE, this CubeSat duo will boost our understanding of how much heat Earth’s polar […]

NASA’s CloudSat Ends Mission Peering Into the Heart of Clouds

An artist’s concept shows NASA’s CloudSat spacecraft in orbit above Earth. Launched in 2006, it provided the first global survey of cloud properties before being decommissioned in March 2024 at the end of its lifespan. NASA/JPL Over the course of nearly two decades, its powerful radar provided never-before-seen details of clouds and helped advance global […]

Tech Today: Folding NASA Experience into an Origami Toolkit 

3 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) Though the art of origami is centuries old, until the late 20th century it was considered virtually impossible to make insects or other figures with many long, complex protrusions. That changed with the introduction of math-based origami design, which Lang helped pioneer. Today, he’s […]

US, Germany Partnering on Mission to Track Earth’s Water Movement

An engineering geologist measures water depth at an agricultural well in a field north of Sacramento, California. Groundwater is an important source of water for irrigation in the state’s Central Valley, especially during times of drought, and the GRACE missions provide data that helps track the resource. Kelly M. Grow/California Department of Water Resources The […]
