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…

The SpaceX Dragon cargo spacecraft is one day away from departing the International Space Station and the Expedition 73 crew members are finishing packing it with science and cargo. The orbital residents also continued their life science activities and lab…

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…

NASA’s X-59 quiet supersonic research aircraft successfully completed a critical series of tests in which the airplane was put through its paces for cruising high above the California desert – all without ever leaving the ground. The goal of ground-based…

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…

The rover took the image — its fifth since landing in February 2021 — between stops investigating the Martian surface. A Martian dust devil photobombed NASA’s Perseverance Mars rover as it took a selfie on May 10 to mark its…

The Discovery A newly discovered planetary system, informally known as 2M1510, is among the strangest ever found. An apparent planet traces out an orbit that carries it far over the poles of two brown dwarfs. This pair of mysterious objects…

Megan Harvey is a utilization flight lead and capsule communicator, or capcom, in the Research Integration Office at NASA’s Johnson Space Center in Houston. She integrates science payload constraints related to vehicles’ launch and landing schedules. She is also working…

Written by Susanne Schwenzer, Planetary Geologist at The Open University Earth planning date: Friday, May 16, 2025 As Curiosity progresses up Mount Sharp, it crosses different terrains, which the team has mapped from orbit. If you want to follow the…

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…

NASA and its international partners will soon receive scientific research samples and hardware after a SpaceX Dragon spacecraft departs the International Space Station on Thursday, May 22, for its return to Earth. Live coverage of undocking and departure begins at…

NASA has signed an agreement with Argentina’s Comisión Nacional de Actividades Espaciales (CONAE) for a CubeSat to fly on the agency’s Artemis II test flight. With this agreement, NASA has finalized all partnerships for the four international CubeSats that will…

Tuesday saw more space biology work aboard the International Space Station helping doctors learn how to protect health and preserve life in microgravity. The Expedition 73 residents also continued their cargo activities packing a U.S. and a Roscosmos cargo craft…

Four NASA astronauts will participate in a welcome home ceremony at Space Center Houston after recently returning from missions aboard the International Space Station. NASA astronauts Nick Hague, Suni Williams, Butch Wilmore, and Don Pettit will share highlights from their…

NASA is demonstrating new microgravity fluids technologies to enable advanced “no-moving-parts” plant-watering methods aboard spacecraft. Crop production in microgravity will be important to provide whole food nutrition, dietary variety, and psychological benefits to astronauts exploring deep space. Unfortunately, even the…

This article is for students grades 5-8. The International Space Station is a large spacecraft in orbit around Earth. It serves as a home where crews of astronauts and cosmonauts live. The space station is also a unique science laboratory. Several…

NASA has a record of Earth observations going back more than 50 years. What might be in store for the next 50 years? In this finale of our Earth series, we hear from two scientists helping to chart the course…

This NASA/ESA Hubble Space Telescope image offers us the chance to see a distant galaxy now some 19.5 billion light-years from Earth (but appearing as it did around 11 billion years ago, when the galaxy was 5.5 billion light-years away…

When future astronauts set foot on Mars, they will stand on decades of scientific groundwork laid by people like Andrea Harrington.   As NASA’s sample return curation integration lead, Harrington is helping shape the future of planetary exploration and paving the…

Written by Ashley Stroupe, Mission Operations Engineer at NASA’s Jet Propulsion Laboratory Earth planning date: Wednesday, May 14, 2025 Today we came into another strange and interesting workspace (see image above) that is as exciting as the one we had…

Scientists expect the new area of interest on the lower slope of Jezero Crater’s rim to offer up some of the oldest rocks on the Red Planet. NASA’s Perseverance Mars rover is exploring a new region of interest the team…

The Expedition 73 crew kicked off the work week studying space biology to learn how to counteract the effects of weightlessness on the human body. The International Space Station residents are also packing the SpaceX Dragon cargo spacecraft for its…

This artist’s concept illustration, released on May 14, 2025, shows a Sun-like star encircled by a disk of dusty debris containing crystalline water ice. Astronomers long expected that frozen water was scattered in systems around stars. By using detailed data…

The numbers are notable – 34 years of testing space shuttle main engines at NASA’s Stennis Space Center near Bay St. Louis, Mississippi, 3,244 individual tests, more than 820,000 seconds (totaling more than nine days) of cumulative hot fire. The…
