São Francisco’s Colorful Palette

An astronaut aboard the International Space Station snapped this photo while in orbit over southeast Brazil. The image focuses on the Três Marias Reservoir, a human-made waterbody fed by the São Francisco River. The types of land cover vary across the image, with bold colors dominating the scene.

A Practiced Escape

Teams at NASA’s Kennedy Space Center in Florida practice the Artemis mission emergency escape, or egress, procedures on Friday, Aug. 9, 2024. Simulated flight crew members practice getting out of the emergency egress basket and into the emergency transport vehicle to drive them to safety in the event of an unlikely emergency during launch countdown.

Earth’s Crest Over the Lunar Horizon

This view of the Earth's crest over the lunar horizon was taken during the Apollo 15 lunar landing mission. Apollo 15 launched from NASA's Kennedy Space Center on July 26, 1971. Aboard was a crew of three astronauts: David R. Scott, James B. Irwin, and Alfred M. Worden. The primary scientific objectives were to observe the lunar surface, survey and sample material and surface features in a preselected area of the Hadley-Apennine region, setup and activation of surface experiments and conduct in-flight experiments and photographic tasks from lunar orbit.

Webb Sees Gassy Baby Stars

In this image of the Serpens Nebula from NASA’s James Webb Space Telescope, astronomers found a grouping of aligned protostellar outflows within one small region (the top left corner). Serpens is a reflection nebula, which means it’s a cloud of gas and dust that does not create its own light, but instead shines by reflecting the light from stars close to or within the nebula.

Carving Canyons

Erosion, tectonic uplift, and a human-built dam have all helped shape the Upper Lake Powell area in Utah.

Europa Clipper Solar Array Alignment and Install

Technicians move NASA’s Europa Clipper spacecraft inside the Payload Hazardous Servicing Facility to accommodate installation of its five-panel solar array at the agency’s Kennedy Space Center in Florida on Thursday, Aug. 1, 2024. After moving the spacecraft, the team had to precisely align the spacecraft in preparation for the installation. The huge arrays – spanning more than 100 feet when fully deployed, or about the length of a basketball court – will collect sunlight to power the spacecraft as it flies multiple times around Jupiter’s icy moon, Europa, conducting science investigations to determine its potential to support life.

Artemis II Core Stage Arrives at Kennedy

Employees from NASA’s Kennedy Space Center in Florida watch as teams with Exploration Ground Systems transport the agency’s powerful SLS (Space Launch System) core stage to the spaceport’s Vehicle Assembly Building on Wednesday, July 24, 2024. The 212-foot-long rocket stage completed its journey from NASA’s Michoud Assembly Facility in New Orleans aboard the Pegasus barge the previous day. Once inside, SLS will be prepared for integration atop the mobile launcher ahead of the Artemis II launch.

Telfer Mine, Western Australia

In the arid outback of Western Australia, miners have excavated rust-colored soil to reach the precious minerals below. The open pits and ponds of Telfer mine can be seen in this image, captured by the OLI-2 (Operational Land Imager-2) on Landsat 9.

Ranger 7 Snaps the Moon

Ranger 7 took this image, the first picture of the Moon by a U.S. spacecraft, on July 31, 1964, about 17 minutes before crashing into the lunar surface.

Transportation Officer Melissa Coleman

"And don't be intimidated or influenced by an emblem or your perception of what kind of people are behind that emblem. Because now I realize, once I've made it to NASA, that it’s nothing like I thought it was. In a lot of ways, it's better, right? Because I get these opportunities to do things that are not in my primary role to serve others, and in that capacity, it's serving me. That’s my advice." — Melissa Coleman, Transportation Officer, Logistics Branch, NASA's Kennedy Space Center

Hubble Images a Classic Spiral

This NASA/ESA Hubble Space Telescope image is a wonderfully detailed snapshot of the spiral galaxy NGC 3430 that lies 100 million light-years from Earth in the constellation Leo Minor.

From Intern to Astronaut

From left to right, NASA astronaut candidates Anil Menon, Deniz Burnham, and Marcos Berrios pose for a photograph in front of NASA’s Artemis I Space Launch System and Orion spacecraft at Launch Complex 39B at the agency’s Kennedy Space Center in Florida on Sept. 2, 2022.

A Saturnian Summer

NASA's Hubble Space Telescope captured this image of Saturn on July 4, 2020. Two of Saturn's icy moons are clearly visible in this exposure: Mimas at right, and Enceladus at bottom. This image is taken as part of the Outer Planets Atmospheres Legacy (OPAL) project. OPAL is helping scientists understand the atmospheric dynamics and evolution of our solar system's gas giant planets. In Saturn's case, astronomers continue tracking shifting weather patterns and storms.

London, UK (SPX) Jul 21, 2024
Several cities in the United States, including the nation's capital, have power grids particularly vulnerable to space weather, according to new research. However, the reasons for this susceptibility remain unclear. The British Geological Survey (BGS) conducted a study revealing that some US regions are more prone to the impacts of geomagnetic storms. These storms are caused by solar flare

New Method to Accurately Predict Solar Storms to Protect Earth's Technology

London, UK (SPX) Jul 21, 2024
Space storms could soon be forecasted with greater accuracy thanks to significant advancements in predicting when a violent solar eruption may impact Earth. Scientists have developed a method to determine the exact speed of a coronal mass ejection (CME) and predict its impact on Earth before it fully erupts from the Sun. CMEs, which are bursts of gas and magnetic fields from the solar atmo
