UT researchers secure $17.8M grant for cutting-edge hypersonic wind tunnel
Tuesday, 24 December 2024 09:16
Researchers from the University of Tennessee, Knoxville, have been awarded a $17.8 million grant by the U.S. Air Force to construct a hypersonic wind tunnel at the UT Space Institute in Tullahoma, Tennessee. The facility will test advanced materials, such as high-temperature ceramics, under the extreme conditions of hypersonic flight - speeds exceeding Mach 5, or five times the speed of sound. First integration of European reusable stage demonstrator Themis
Tuesday, 24 December 2024 09:16
ArianeGroup has successfully completed the initial mechanical integration of Themis, the European reusable launcher first stage demonstrator, at its Les Mureaux facility in France.
Standing 28 meters tall, the prototype comprises the Multi-Engine Bay (MEB), tanks, the Flight Control Bay (FCB), and the upper segment that completes the stage structure.

Tuesday, 24 December 2024 09:16
The Jovian Vortex Hunter project has released a groundbreaking catalog of 7,222 atmospheric vortices on Jupiter, showcasing immense swirling storms captured over the last two years. Each vortex represents a powerful atmospheric phenomenon within the gas giant's turbulent skies, with thousands of volunteers contributing to this unprecedented effort.
Vortices are categorized by color, with " Cutting edge satellite monitors water levels in Ohio River Basin
Tuesday, 24 December 2024 09:16
The Ohio River Basin, spanning from Pennsylvania to Illinois, covers an area nearly as large as France and is home to over 25 million people. A collaborative effort between NASA and the French space agency CNES (Centre National d'Etudes Spatiales) through the Surface Water and Ocean Topography (SWOT) mission now provides researchers with a valuable tool to monitor water levels in lakes, reservoi Dark energy theory challenged by evidence of a 'lumpy' Universe
Tuesday, 24 December 2024 09:16
A groundbreaking study from researchers at the University of Canterbury in New Zealand proposes that dark energy, a long-debated concept in cosmology, may not exist. Using improved supernovae light curve analyses, the team argues the Universe's expansion is far more irregular than previously believed, rendering dark energy unnecessary to explain its accelerating rate.
For over a century, p Webb Telescope detects new population of small Main Belt Asteroids
Tuesday, 24 December 2024 09:16
The James Webb Space Telescope (JWST) has expanded its role in solar system research, revealing a previously undetectable population of small asteroids within the main asteroid belt between Mars and Jupiter.
A team from the Massachusetts Institute of Technology (MIT) used Webb's observations of the star TRAPPIST-1 to identify 138 new asteroids ranging in size from a bus to a stadium. These Lab experiments explore origins of gullies on Asteroid Vesta
Tuesday, 24 December 2024 09:16
The rugged surface of asteroid Vesta, studied extensively by NASA's Dawn mission, features craters and mysterious gullies whose formation has puzzled scientists. These deep channels, previously hypothesized to result from debris flows driven by meteoroid impacts and temperature changes, are now thought to involve a surprising factor: brief flows of water.
A recent NASA-funded study, publis SpaceX launches 21 Starlink satellites from Florida
Tuesday, 24 December 2024 09:16
Shortly after midnight on Monday, SpaceX launched a new round of 21 Starlink satellites into lower Earth orbit, 13 of which can contact cell phones directly.
The Falcon 9 rocket blasted off from the Kennedy Space Center in Florida at 12:35 a.m., EDT. The first stage, making its 15th trip, landed safely on the drone ship "Just Read the Instructions" about eight minutes after the launch. Unveiling hidden stars in the Milky Way with stellar orbital mapping
Tuesday, 24 December 2024 09:16
A research team led by the Leibniz Institute for Astrophysics Potsdam (AIP) has pioneered a method to reconstruct the Milky Way's structure by mapping the orbits of stars. This approach reveals a deeper understanding of the galaxy's evolution and the distribution of stellar populations.
Despite advances in observational astronomy, much of the Milky Way remains hidden due to the obscuring e New commercial Artemis moon rovers undergo testing at NASA
