NASA/Carla Thomas NASA’s X-59 quiet supersonic research aircraft completed its first low-speed taxi test at U.S. Air Force Plant 42 in Palmdale, California, on July 10, 2025. This marked the first time the one-of-a-kind experimental aircraft has ever moved under its own power. During the test, engineers and flight crews monitored the X-59 as it moved across the runway, working to validate critical systems like steering and braking. The taxiing represents the start of the X-59’s final series of ground tests before first flight. The X-59 is the centerpiece of NASA’s Quesst mission, which aims to demonstrate quiet supersonic flight by reducing the loud sonic boom…

On July 19, 2013, in an event celebrated the world over, NASA’s Cassini spacecraft slipped into Saturn’s shadow and turned to image the planet, seven of its moons, its inner rings, and, in the background, our home planet, Earth.NASA/JPL-Caltech/SSI On July 19, 2013, NASA’s Cassini spacecraft had a rare opportunity to image Saturn and, far in the background, Earth. This image spans about 404,880 miles (651,591 kilometers) across. With the Sun’s powerful and potentially damaging rays eclipsed by Saturn itself, Cassini’s onboard cameras were able to take advantage of this unique viewing geometry. They acquired a panoramic mosaic of the Saturn system that allows scienti…

A lifelong baseball fan, Catherine Staggs set out with her family to visit all 30 Major League Baseball stadiums across the United States. That love of the game eventually led them to settle in Houston about eight years ago – a choice that helped lead Staggs to NASA’s Johnson Space Center, where she is a contracting officer for the agency’s Commercial Lunar Payload Services (CLPS) initiative. Through CLPS, she helps manage the contracts with commercial companies delivering science and technology to the Moon. These efforts support NASA’s Artemis campaign and lay the groundwork for continuous human presence on the lunar surface. Official portrait of Catherine Staggs…

4 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) NASA’s Athena Economical Payload Integration Cost mission, or Athena EPIC, is a test launch for an innovative, scalable space vehicle design to support future missions. The small satellite platform is engineered to share resources among the payloads onboard by managing routine functions so the individual payloads don’t have to. This technology results in lower costs to taxpayers and a quicker path to launch. Fully integrated, the Athena EPIC satellite undergoes performance testing in a NovaWurks cleanroom to prepare the sensor for launch. The optical module payload element may be seen…

This NASA/ESA Hubble Space Telescope image features the galaxy cluster Abell 209.ESA/Hubble & NASA, M. Postman, P. Kelly A massive, spacetime-warping cluster of galaxies is the setting of today’s NASA/ESA Hubble Space Telescope image. The galaxy cluster in question is Abell 209, located 2.8 billion light-years away in the constellation Cetus (the Whale). This Hubble image of Abell 209 shows more than a hundred galaxies, but there’s more to this cluster than even Hubble’s discerning eye can see. Abell 209’s galaxies are separated by millions of light-years, and the seemingly empty space between the galaxies is filled with hot, diffuse gas that is visible only at …

KEY POINTS Jupiter, Saturn, and Neptune each emit more energy than they receive from the Sun, meaning they have comparatively warm interiors. NASA’s Uranus flyby with Voyager 2 in 1986 found the planet colder than expected, which challenged ideas of how planets formed and evolved. However, with advanced computer modeling and a new look at old data, scientists think the planet may actually be warmer than previously expected. For millennia, astronomers thought Uranus was no more than a distant star. It wasn’t until the late 18th century that Uranus was universally accepted as a planet. To this day, the ringed, blue world subverts scientists’ expectations, but new NASA r…
