Published Fossils of giant sea lizard that ruled the oceans 66 million years ago discovered
(via sciencedaily.com) Fossils of a giant killer mosasaur have been discovered, along with the fossilized remains of its prey.
Published NASA schedules PUNCH mission to launch in 2025
(via sciencedaily.com) More than 60 engineers and scientists are gathering at Southwest Research Institute Aug. 23-24 to kick off the launch vehicle collaboration for NASA's Polarimeter to Unify the Corona and Heliosphere (PUNCH) mission. PUNCH, which will study the inception of the solar wind, has secured its ride into Earth orbit aboard a SpaceX Falcon 9, sharing a ride into space with NASA's Spectro-Photometer for the History of the Universe, Epoch of Re-ionization, and Ices Explorer (SPHEREx) mission.
Published Saturn V was loud but didn't melt concrete
(via sciencedaily.com) Abundant internet claims about the acoustic power of the Saturn V suggest that it melted concrete and lit grass on fire over a mile away, but such ideas are undeniably false. Researchers used a physics-based model to estimate the rocket's acoustic levels and obtained a value of 203 decibels, which matched the limited data from the 1960s. So, while the Saturn V was extremely loud, that kind of power is nowhere near enough to melt concrete or start grass fires.
Published Seeing universe's most massive known star
(via sciencedaily.com) By harnessing the capabilities of the Gemini South telescope in Chile, astronomers have obtained the sharpest image ever of the star R136a1, the most massive known star in the universe. Their research challenges our understanding of the most massive stars and suggests that they may not be as massive as previously thought.
Published Compact QKD system paves the way to cost-effective satellite-based quantum networks
(via sciencedaily.com) Researchers report an experimental demonstration of a space-to-ground quantum key distribution (QKD) network using a compact QKD terminal aboard the Chinese Space Lab Tiangong-2 and four ground stations. The demonstration represents an important step toward practical QKD based on constellations of small satellites, a setup considered one of the most promising routes to creating a global quantum communication network.
Published Breaking in a new planet
(via sciencedaily.com) Impacts affect the porosity and structure of moons and planets more dramatically than scientists suspected, increasing their potential habitability for life. Studying how those impacts affect planetary bodies, asteroids, moons and other rocks in space helps planetary scientists understand extraplanetary geology, especially where to look for precious matter including water, ice and even, potentially, microbial life.
Published Mars model provides method for landing humans on Red Planet
(via sciencedaily.com) A mathematical model developed by space medicine experts could be used to predict whether an astronaut can safely travel to Mars and fulfill their mission duties upon stepping foot on the Red Planet.
Published Wobbling droplets in space confirm late professor's theory
(via sciencedaily.com) At a time when astronomers around the world are reveling in new views of the distant cosmos, an experiment on the International Space Station has given researchers fresh insight into something a little closer to home: water.
Published Harvesting resources on Mars with plasmas
(via sciencedaily.com) Researchers have devised a plasma-based way to produce and separate oxygen within the Martian environment. It's a complementary approach to NASA's Mars Oxygen In-Situ Resource Utilization Experiment and may deliver high rates of molecule production per kilogram of instrumentation sent to space. The team presents the method for harnessing and processing local resources to generate products on Mars.
Published All the better to better eat you with -- dinosaurs evolved different eye socket shapes to allow stronger bites
(via sciencedaily.com) Large dinosaur predators, such as Tyrannosaurus rex, evolved different shapes of eye sockets to better deal with high bite forces, new research has shown.
Published Prehistoric podiatry: How dinos carried their enormous weight
(via sciencedaily.com) Scientists have cracked an enduring mystery, discovering how sauropod dinosaurs -- like Brontosaurus and Diplodocus -- supported their gigantic bodies on land.
Published Building on the moon and Mars? You'll need extraterrestrial cement for that
(via sciencedaily.com) Researchers are exploring ways to use clay-like topsoil materials from the moon or Mars as the basis for extraterrestrial cement that could be used by astronauts to create building materials for life in outer space. Scientists have converted simulated lunar and Martian soils into geopolymer cement, which is considered a good substitute for conventional cement.
Published The speed at which spinosaurid dinosaur teeth were replaced accounts for their overabundance in Cretaceous sites
(via sciencedaily.com) Spinosaurid dinosaurs were able to develop up to three generations of teeth at the same time, a high replacement rate that explains why so many teeth of this type have been found in Cretaceous sites.
Published Robotic motion in curved space defies standard laws of physics
(via sciencedaily.com) Researchers have proven that when bodies exist in curved spaces, they can in fact move without pushing against something.
Published As reflective satellites fill the skies, students are making sure astronomers can adapt
(via sciencedaily.com) Students have completed a comprehensive brightness study to characterize mega-constellation satellites cluttering the skies.
Published Webb captures stellar gymnastics in the Cartwheel Galaxy
(via sciencedaily.com) NASA's James Webb Space Telescope has peered into the chaos of the Cartwheel Galaxy, revealing new details about star formation and the galaxy's central black hole.
Published Modeling reveals how dwarf planet Ceres powers unexpected geologic activity
(via sciencedaily.com) Original source For a long time, our view of Ceres was fuzzy, according to a geoscientist. A dwarf planet and the largest body found in the asteroid belt -- the region between Jupiter and Mars speckled with hundreds of thousands of asteroids -- Ceres had no distinguishable surface features in existing telescopic observations from Earth.
Published Space travel: Bone aging in fast forward
(via sciencedaily.com) Long periods in space damage bone structure irreparably in some cases and can make parts of the human skeleton age prematurely by up to 10 years, according to new research. Adapted training programs in conjunction with medication could provide better protection for astronauts on future space missions. The research findings also have implications for treating rheumatic conditions in clinical practice.
Published Plesiosaur fossils found in the Sahara suggest they weren't just marine animals
(via sciencedaily.com) Fossils of small plesiosaurs, long-necked marine reptiles from the age of dinosaurs, have been found in a 100-million year old river system that is now Morocco's Sahara Desert. This discovery suggests some species of plesiosaur, traditionally thought to be sea creatures, may have lived in freshwater.
Published Scientists discover places on the moon where it's always 'sweater weather'
(via sciencedaily.com) A team led by planetary scientists has discovered shady locations within pits on the moon that always hover around a comfortable 63 degrees Fahrenheit. The pits, and caves to which they may lead, would make safer, more thermally stable base camps for lunar exploration and long-term habitation than the rest of the moon's surface, which heats up to 260 degrees during the day and drops to 280 degrees below zero at night.
