Preguntas frecuentes: La verdadera historia del cuidado de la salud de los astronautas en el espacio
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…
The Real Story About Astronaut Health Care in Space
Lee esta historia en español aquí. The International Space Station is humanity’s home in space and a research station orbiting about 250 miles above the Earth. NASA and its international partners have maintained a continuous human presence aboard the space…
Ready, Set, Action! Our Sun is the Star in Dazzling Simulation
NASA supercomputers are shedding light on what causes some of the Sun’s most complex behaviors. Using data from the suite of active Sun-watching spacecraft currently observing the star at the heart of our solar system, researchers can explore solar dynamics like never…
NASA: Mystery of Life’s Handedness Deepens
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…
NASA’s Hubble Finds Sizzling Details About Young Star FU Orionis
In 1936, astronomers saw a puzzling event in the constellation Orion: the young star FU Orionis (FU Ori) became a hundred times brighter in a matter of months. At its peak, FU Ori was intrinsically 100 times brighter than our…
Extratropical Cyclone Whips Over the Pacific Northwest
Damaging winds from the strong storm knocked out power for thousands of people in Washington state.

Weld-ASSIST: Weldability Assessment for In-Space Conditions using a Digital Twin
ESI24 Haghighi Quadchart Azadeh HaghighiUniversity of Illinois, Chicago In-space manufacturing and assembly are vital to NASA’s long-term exploration goals, especially for the Moon and Mars missions. Deploying welding technology in space enables the assembly and repair of structures, reducing logistical burdens…
Integrated Computational Materials Modelling Framework for Investigating the Process-Structure-Property Linkage of the Lunar Metal Welding with Internal Defects
ESI24 Li Quadchart Wei LiUniversity of Texas at Dallas Internal defects are always formed in laser welding process due to the keyhole instability, molten pool collapse, and rapid solidification. The extreme lunar environment complicates the reliable implementation of welding, thereby enhancing…
Deformable Crumpled Nano-ball Coatings with Adaptable Adhesion and Mechanical Energy Absorption for Lunar Dust Mitigation
ESI24 Nam Quadchart SungWoo NamUniversity 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…
Engineering the Adhesion Mechanisms of Hierarchical Dust-Mitigating Nanostructures
ESI24 Chang Quadchart Chih-Hao ChangUniversity of Texas at Austin Establishing a permanent base on the moon is a critical step in the exploration of deep space. One significant challenge observed during the Apollo missions was the adhesion of lunar dust, which…
Studying Passive Dust Mitigation on Anisotropic Structured Surface
ESI24 Zhai Quadchart Lei ZhaiUniversity of Central Florida Lunar dust, with its chemical reactivity, electrostatic charge, and potential magnetism, poses a serious threat to astronauts and equipment on the Moon’s surface. To address this, the project proposes developing structured coatings with…
Developing High-Performance Bioinspired Surface Textures for Repelling Lunar Dust
ESI24 Zou Quadchart Min ZouUniversity of Arkansas, Fayetteville Lunar dust, with its highly abrasive and electrostatic properties, poses serious threats to the longevity and functionality of spacecraft, habitats, and equipment operating on the Moon. This project aims to develop advanced…
Sols 4368-4369: The Colors of Fall – and Mars
Earth planning date: Monday, Nov. 18, 2024 I am in the U.K., where we are approaching the time when trees are just branches and twigs. One tree that still has its full foliage is my little quince tree in my…
NASA, SpaceX Illustrate Key Moments of Artemis Lunar Lander Mission
NASA is working with U.S. industry to develop the human landing systems that will safely carry astronauts from lunar orbit to the surface of the Moon and back throughout the agency’s Artemis campaign. For Artemis III, the first crewed return…
NASA’s Chandra, Hubble Tune Into ‘Flame-Throwing’ Guitar Nebula
Normally found only in heavy metal bands or certain post-apocalyptic films, a “flame-throwing guitar” has now been spotted moving through space. Astronomers have captured movies of this extreme cosmic object using NASA’s Chandra X-ray Observatory and Hubble Space Telescope. The…
