In the absence of gravity, water in space exhibits distinct behaviors. Surface tension and capillary flow, phenomena that arise due to these altered conditions, can be leveraged to facilitate the movement of fluids with increased efficiency. What may initially seem like a recreational endeavor holds the potential to yield practical benefits in enhancing fluid transport systems for microgravity environments, such as those found in the fuel tanks of spacecraft used for space travel. #SpaceX,#NASA,#Astronomy,#CosmicExploration,#SpaceDiscoveries,#UniverseMysteries,#Astrobiology,#StellarJourney,#GalacticWonders,#MarsExploration,#Universe,#Cosmos,#SpaceMissions,#Stargazing,#SpaceScience,#Astrophotography,#SpaceExploration

Embark on an immersive virtual journey to the Moon, now available in stunning 4K resolution, courtesy of data furnished by NASA's Lunar Reconnaissance Orbiter spacecraft. As this captivating visualization guides you through the Moon's various facets—the near side, the far side, and the polar regions—it brings into focus intriguing landmarks, sites, and invaluable insights collected about the lunar landscape. Accompanying your voyage is a musical backdrop provided by Killer Tracks, featuring compositions like "Never Looking Back" by Frederick Wiedmann and "Flying over Turmoil" by Benjamin Krause & Scott Goodman.

NASA astronaut Scott Kelly, who marked day 300 of a historic year in space on Jan. 21, 2016, shows off another fascinating feature of life in microgravity. Kelly used two paddles with hydrophobic, or water repellant, features to pass a sphere of water back and forth. Scientists use the microgravity environment of the space station to advance scientific knowledge in Earth, space, physical, and biological sciences that otherwise wouldn't be possible down here on the planet. The paddles are polycarbonate laser etched so that the surfaces are actually arrays of 300 micrometer posts (0.3mm). The surfaces were then spray coated with a Teflon coat. The combined effects of surface roughness and non-wettability produce a super-hydrophobic surface capable of preventing water adhesion in dynamic processes. The larger the drop, the less force it takes to break it up. The smaller the drop, the harder you can hit it. Scott is demonstrating about a 4 mL drop (over 100 times larger than a rain drop).

At Lockheed Martin Space in Littleton, Colorado, NASA's Lucy mission has undergone testing for the deployment of its expansive solar arrays within a thermal vacuum chamber. Each of these circular arrays boasts an impressive width of nearly 24 feet (7.3 meters). These exceptional arrays are set to provide the essential power source for Lucy during its ambitious 12-year expedition through the Jupiter Trojan asteroids. This mission sets a new benchmark for solar-powered endeavors, spanning a staggering 530 million miles (853 million kilometers) from the Sun. The considerable scale of these solar arrays is essential, as they are designed to capture the sunlight required to fuel the spacecraft as it voyages through the expanse of deep space.

In 2018, NASA's OSIRIS-REx mission began its residence on Bennu, an asteroid comparable in height to a skyscraper and positioned remarkably close to Earth. The mission intricately observed Bennu, creating an intricate tapestry of data since its arrival on December 3, 2018. As of May 10, 2021, OSIRIS-REx embarks on its journey back to Earth, carrying a valuable payload of over 60 grams of asteroid samples. This narrated video comprehensively portrays the mission's trajectory during its tenure at Bennu. Additional information can be found at nasa.gov/osiris-rex. The musical accompaniment features "Visionary" by Andy Blythe and Marten Joustra, as well as "Babel" by Max Cameron Concors, courtesy of Universal Production Music. The data originates from collaborative efforts involving NASA, University of Arizona, CSA, York University, Open University, and MDA. Video production credits belong to NASA's Goddard Space Flight Center and its Scientific Visualization Studio, with Dan Gallagher (USRA) and Kel Elkins (USRA) as Producers, Kel Elkins (USRA) as Lead Data Visualizer, Dan Gallagher (USRA) as the Narrator, Michael Moreau (NASA/GSFC) as Deputy Project Manager, Dante Lauretta (The University of Arizona) as Principal Investigator, and Kenny Getzandanner (NASA/GSFC) among the contributors.#NASA#Space #Astronomy #SpaceExploration #Universe #Cosmos#SpaceMissions #Stargazing #SpaceScience #Astrophotography

This high-resolution 4K presentation illustrates the Moon's phase and libration with hourly updates throughout the year 2022. The perspective is that of an observer in the Northern Hemisphere. Each frame in the visualization represents a span of one hour. Alongside, the animation displays the Moon's orbital position, points of sub-Earth and subsolar illumination, and its accurate distance from Earth. The scale is maintained true to reality. Notably, craters located near the lunar terminator are identified, as well as significant features like Apollo landing sites and maria, all illuminated by sunlight. The video is attributed to NASA's Goddard Space Flight Center, with data visualization crafted by Ernie Wright (USRA), and production and editing overseen by David Ladd (AIMM). The musical accompaniment "Build the Future" is provided by Universal Production Music. #SpaceX #NASA #Astronomy #CosmicExploration #SpaceDiscoveries #UniverseMysteries #Astrobiology #StellarJourney #GalacticWonders #MarsExploration

While the Apollo missions marked humanity's initial footsteps on the Moon, Artemis represents a pivotal era where we are poised to establish a sustainable human presence on another celestial body for the very first time. By utilizing the lunar environment as a testing ground for Mars habitation, this new phase in exploration will cement our enduring connection with the cosmos. ✨ Our journey back to the Moon is now a permanent endeavor, and we're forging ahead with unwavering determination. Actress Kelly Marie Tran, known for her role in "Star Wars: The Rise of Skywalker," has lent her voice to this endeavor. #NASA #SpaceExploration #Astronomy #SpaceDiscoveries #SpaceMissions #CosmicWonders #Astrophysics #UniverseExploration #SpaceScience #StellarJourney #SpaceX #NASA #Astronomy #CosmicExploration #SpaceDiscoveries #UniverseMysteries #Astrobiology #StellarJourney #GalacticWonders #MarsExploration
