NASA/Michael DeMocker Just after sunrise, the waning gibbous moon sets just behind a waving United States flag on March 19, 2025, in this image from NASA’s Michoud Assembly Facility in New Orleans. The waning gibbous moon phase comes after the full moon. As the Moon begins its journey back toward the Sun, the opposite side of the Moon now reflects the Moon’s light. The lighted side appears to shrink, but the Moon’s orbit is simply carrying it out of view from our perspective. The Moon also rises later and later each night.

In collaboration with the United States Department of Agriculture, Amazon Web Services, and Colorado State University, NASA turned to students for AI-driven solutions. NASA On March 28, 80 college students filed into Colorado State University’s (CSU) Nancy Richardson Design Center to receive pizza and a challenge: design an intelligent system capable of traversing rugged terrain to provide aid in emergency scenarios. They had 24 hours to complete this mission. Co-led by CSU, the United States Department of Agriculture (USDA) Forest Service, and NASA, the Spring 2025 CSU Hackathon forged a symbiotic relationship between federal agencies looking for novel AI solu…

Credit: NASA The United States participated in an international Artemis Accords workshop May 21-22 to advance the safe and responsible exploration of the Moon, Mars, and beyond. Hosted by the United Arab Emirates (UAE), which was represented by the UAE Space Agency, the workshop took place at the Abu Dhabi National Exhibition Centre. The Artemis Accords are a set of non-binding principles signed by nations for a peaceful and prosperous future in space for all of humanity to enjoy. In October 2020, under the first Trump administration, the accords were created, and since then, 54 countries have joined with the United States in committing to transparent and responsibl…

5 min read Percolating Clues: NASA Models New Way to Build Planetary Cores NASA’s Perseverance rover was traveling in the channel of an ancient river, Neretva Vallis, when it captured this view of an area of scientific interest nicknamed “Bright Angel” – the light-toned area in the distance at right. The area features light-toned rocky outcrops that may represent either ancient sediment that later filled the channel or possibly much older rock that was subsequently exposed by river erosion. NASA/JPL-Caltech A new NASA study reveals a surprising way planetary cores may have formed—one that could reshape how scientists understand the early evolution of rocky pla…

6 min read NASA’s Dragonfly Mission Sets Sights on Titan’s Mysteries When it descends through the thick golden haze on Saturn’s moon Titan, NASA’s Dragonfly rotorcraft will find eerily familiar terrain. Dunes wrap around Titan’s equator. Clouds drift across its skies. Rain drizzles. Rivers flow, forming canyons, lakes and seas. Artist’s concept of NASA’s Dragonfly on the surface of Saturn’s moon Titan. The car-sized rotorcraft will be equipped to characterize the habitability of Titan’s environment, investigate the progression of prebiotic chemistry in an environment where carbon-rich material and liquid water may have mixed for an extended period, and even sear…

5 Min Read NASA Knows: What is Lunar Regolith? (Grades 5-8) This article is for students grades 5-8. The surface of the Moon is covered in a thick layer of boulders, rocks, and dust. This dusty, rocky layer is called lunar regolith. It was created a long time ago when meteorites crashed into the Moon and broke up the ground. NASA scientists study the regolith to learn more about the Moon’s history. But the smallest parts of the regolith make exploring the Moon very hard! That is why scientists are working to understand it better and to keep astronauts safe during future lunar missi…

6 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) The SWOT satellite is helping scientists size up flood waves on waterways like the Yellowstone River, pictured here in October 2024 in Montana. SWOT measures the height of surface waters, including the ocean, and hundreds of thousands of rivers, lakes, and reservoirs in the U.S. alone.NPS In a first, researchers from NASA and Virginia Tech used satellite data to measure the height and speed of potentially hazardous flood waves traveling down U.S. rivers. The three waves they tracked were likely caused by extreme rainfall and by a loosened ice jam. While there is currently no database that c…

2 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) How big is space? Space is really big. Thinking about our solar system, let’s imagine you could get in a car and drive to Pluto at highway speeds. It would take you about 6,000 years to get there. When we start to think about other stars outside of our solar system, we need to think about another unit of distance. This is why astronomers use the unit light-years. Light travels at 186,000 miles per second. One light year is about 6 trillion miles. The closest star to our Sun is about four light years away. Our own Milky Way galaxy is about 10…

NASA/JPL-Caltech/Texas A&M/Cornell NASA’s Mars Exploration Rover Spirit captured this stunning view as the Sun sank below the rim of Gusev crater on Mars 20 years ago. In this image, the bluish glow in the sky above the Sun would be visible to us if we were there, but an artifact of the panoramic camera’s infrared imaging capabilities is that with this filter combination, the redness of the sky farther from the sunset is exaggerated compared to the daytime colors of the Martian sky.
