A cyclone is a low-pressure area of winds that spiral inwards. Although tropical storms most often come to mind, these spiraling storms can also form at mid- and high latitudes. Two such cyclones formed in tandem south of Iceland in November 2006.NASA/Jesse Allen The Moderate Resolution Imaging Spectroradiometer flying aboard NASA’s Terra satellite took this picture of two cyclones near Iceland on Nov. 20, 2006. Though we usually think of cyclones occurring in the tropics, these spiraling storms can also form at mid- and high latitudes. Cyclones at these latitudes are actually fairly common, and they drive much of the Earth’s weather. Image credit: NASA/Jesse Allen …

NASA’s Human Landing System (HLS) will transport the next astronauts that land on the Moon, including the first woman and first person of color, beginning with Artemis III. For safety and mission success, the landers and other equipment in development for NASA’s Artemis campaign must work reliably in the harshest of environments. The Hub for Innovative Thermal Technology Maturation and Prototyping (HI-TTeMP) lab at NASA’s Marshall Space Flight Center in Huntsville, Alabama, provides engineers with thermal analysis of materials that may be a prototype or in an early developmental stage using a vacuum chamber, back left, and a conduction chamber, right.

NASA Read this story in English here. La Estación Espacial Internacional es el hogar de la humanidad en el espacio y una estación de investigación que gira en órbita sobre la Tierra a unos 400 kilómetros (250 millas) de altura. La NASA y sus socios internacionales han mantenido una presencia humana continua a bordo de la estación espacial durante más de 24 años, haciendo investigaciones que no es posible realizar en la Tierra. La gente que vive y trabaja a bordo de este laboratorio en microgravedad también forma parte de las investigaciones que se llevan a cabo, y ellos ayudan a abordar complejos problemas de la salud humana en la Tierra y preparan a la humanida…

NASA/JPL-Caltech This Oct. 4, 2017, illustration shows a hypothetical uneven ring of dust orbiting KIC 8462852, also known as Boyajian’s Star or Tabby’s Star. The star has experienced unusual dips in brightness over a matter of days, as well as much subtler but longer-term dimming trends. Scientists proposed several explanations for this unexpected behavior, ranging from Tabby’s Star swallowing a planet to alien “megastructures” harvesting the star’s energy. However, a study using NASA’s Spitzer and Swift missions as well as the Belgian AstroLAB IRIS observatory suggests that the cause of the dimming over long periods is likely an uneven dust cloud moving around the sta…

4 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) The mystery of why life uses molecules with specific orientations has deepened with a NASA-funded discovery that RNA — a key molecule thought to have potentially held the instructions for life before DNA emerged — can favor making the building blocks of proteins in either the left-hand or the right-hand orientation. Resolving this mystery could provide clues to the origin of life. The findings appear in research recently published in Nature Communications. Proteins are the workhorse molecules of life, used in everything from structures like hair to enzymes (catalysts that speed up or reg…

The extreme lunar environment complicates the reliable implementation of welding, thereby enhancing the welding defects formation. The welding defects are critical material barriers preventing the metal components from Moon exploration.

2 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) ESI24 Nam Quadchart SungWoo Nam University of California, Irvine Lunar dust may seem unimposing, but it presents a significant challenge for space missions. Its abrasive and jagged particles can damage equipment, clog devices, and even pose health risks to astronauts. This project addresses such issues by developing advanced coatings composed of crumpled nano-balls made from atomically thin 2D materials such as MoS₂, graphene, and MXenes. By crumpling these nanosheets—much like crumpling a piece of paper—we create compression and aggregation resistant particles that can be dispersed …

One significant challenge observed during the Apollo missions was the adhesion of lunar dust, which can build up on vehicle, equipment, and space suit. Highly fine and abrasive, the dust particles can have adverse mechanical, electrical, and health effects. The proposed research aims to develop a new class of hierarchical, heterogenous nanostructured coating that can passively mitigate adhesion of lunar particles. Using scal…
