Marsquakes may help reveal whether liquid water exists underground on red planet
Thursday, 20 June 2024 23:09If liquid water exists today on Mars, it may be too deep underground to detect with traditional methods used on Earth. But listening to earthquakes that occur on Mars - or marsquakes - could offer a new tool in the search, according to a team led by Penn State scientists. When quakes rumble and move through aquifers deep underground, they produce electromagnetic signals. The researchers re
Laying the foundation for lunar base construction; elucidating lunar soil-microwave interactions
Thursday, 20 June 2024 23:09KICT Studies Microwave Sintering of Lunar Soil for Moon Base Construction NASA's Artemis program aims to build a lunar base, but transporting construction materials from Earth to the Moon is expensive. To overcome this, researchers are exploring the use of local materials like lunar soil. One method being studied is microwave sintering, which solidifies lunar regolith without melting it. T
Iron meteorites hint that our infant solar system was more doughnut than dartboard
Thursday, 20 June 2024 23:09Four and a half billion years ago, our solar system was a cloud of gas and dust swirling around the sun, until gas began to condense and accrete along with dust to form asteroids and planets. What did this cosmic nursery, known as a protoplanetary disk, look like, and how was it structured? Astronomers can use telescopes to "see" protoplanetary disks far away from our much more mature solar syst
UH scientists discover massive energy imbalance on Saturn
Thursday, 20 June 2024 23:09A groundbreaking discovery by researchers at the University of Houston has revealed a massive energy imbalance on Saturn, shedding new light on planetary science and evolution and challenging existing climate models for the solar system's gas giants. The findings appear in the scientific publication Nature Communications. "This is the first time that a global energy imbalance on a seasonal
Titan's lakes may be shaped by waves
Thursday, 20 June 2024 23:09Titan, Saturn's largest moon, is the only other planetary body in the solar system that currently hosts active rivers, lakes, and seas. These otherworldly river systems are thought to be filled with liquid methane and ethane that flows into wide lakes and seas, some as large as the Great Lakes on Earth. The existence of Titan's large seas and smaller lakes was confirmed in 2007, with image
French-Chinese probe to hunt universe's biggest explosions
Thursday, 20 June 2024 23:09A French-Chinese telescope satellite will blast off this weekend on a mission to hunt down gamma-ray bursts, the most powerful explosions in the universe. The light from these almighty blasts has travelled billions of light years to reach Earth, so scientists believe they could hold answers to some mysteries of the universe's youth. But these flashes are so brief they have proved difficu
New Evidence Suggests Dark Matter Influence Extends Further Than Thought
Thursday, 20 June 2024 23:09Scientists at Case Western Reserve University have discovered new evidence that could reshape our understanding of the cosmos. Tobias Mistele, a post-doctoral scholar in the Department of Astronomy at Case Western Reserve's College of Arts and Sciences, used "gravitational lensing" to study dark matter. He found that the rotation curves of galaxies remain flat for millions of light years.
Solar Orbiter Observes Major Solar Activity
Thursday, 20 June 2024 23:09The hyperactive sunspot region responsible for the beautiful auroras earlier in May was still alive and kicking when it rotated away from Earth's view. Watching from the other side of the Sun, the ESA-led Solar Orbiter mission detected this same region producing the largest solar flare of this solar cycle. By observing the Sun from all sides, ESA missions reveal how active sunspot regions evolve
Iridium Expands Satellite Time and Location Service to Europe and Asia Pacific
Thursday, 20 June 2024 23:09Iridium Communications Inc. (Nasdaq: IRDM), a provider of global voice and data satellite communications, announced the expanded commercial availability of its Satellite Time and Location (STL) service. Iridium partners are now authorized to sell the service in parts of Europe and Asia Pacific. The STL service is designed to protect GNSS systems, like GPS and Galileo, with a signal resista
SES completes euro 3 billion acquisition financing syndication
Thursday, 20 June 2024 23:09SES S.A. has successfully syndicated a euro 3 billion acquisition financing package to support its earlier agreement to acquire Intelsat S.A. Deutsche Bank AG and Morgan Stanley underwrote a euro 3 billion bridge facility to support SES's financing needs as part of the agreement. The euro 3 billion bridge facility has now been syndicated with a high level of commitments to an international

Thursday, 20 June 2024 18:00Next-generation NASA technologies tested in flight
Thursday, 20 June 2024 17:55Teams of NASA researchers put their next-generation technologies to the microgravity test in a series of parabolic flights that aim to advance innovations supporting the agency's space exploration goals.
These parabolic flights provide a gateway to weightlessness, allowing research teams to interact with their hardware in reduced gravity conditions for intervals of approximately 22 seconds. The flights, which ran from February to April, took place aboard Zero Gravity Corporation's G-FORCE ONE aircraft and helped to advance several promising space technologies.
Under the Fundamental Regolith Properties, Handling, and Water Capture (FLEET) project, researchers tested an ultrasonic blade technology in a regolith simulant at lunar and Martian gravities. On Earth, vibratory tools reduce the forces between the tool and the soil, which also lowers the reaction forces experienced by the system.
