New research published ahead of print in the Journal of Applied Physiology suggests women lose more muscle than men in a microgravity environment such as spaceflight. The study “represent[s] the longest bed rest study on a large cohort of women” and underscores the need for more sex-specific studies on physiological responses to microgravity, the research team wrote. …read more […] The solar wings that will power ESA’s Hera asteroid mission for planetary defense as it ventures out to meet the Dimorphos asteroid have been cleared for flight. As part of its current test campaign at ESA’s ESTEC Test Center in the Netherlands, the spacecraft commanded the deployment of the wings one at a time, as it will do in space directly after launch—known as a “hot deployment.” …read more […] A team of astrophysicists led by Lauren Weiss, assistant professor in the Department of Physics and Astronomy at the University of Notre Dame, created the first-ever catalog of small, Earth-like planets with Jupiter-like siblings (planets that share the same star)—a critical component in the search for life elsewhere in our universe. …read more […] Telescopes have been collecting copious amounts of data on exoplanets in recent years. One of the most common datasets tracks what are known as transits, when an exoplanet crosses in front of its host star and dims the star’s light slightly as it does so. The majority of exoplanets have been found this way, but other interesting details might be hidden in the data. …read more […] The generation and manipulation of high-repetition pulses hold great promise across various applications, including high-speed photography, laser processing, and acoustic wave generation. Gigahertz (GHz) burst pulses, with intervals ranging from ~0.01 to ~10 nanoseconds, are particularly valued for visualizing ultrafast phenomena and improving laser processing efficiency. …read more […] Blue Origin launched its first rocket in more than a year on Tuesday, reviving the US company’s fortunes with a successful return to space following an uncrewed crash in 2022. …read more […] On Aug. 18, 2023, the Mars Reconnaissance Orbiter (MRO) captured ridged lines carved onto Mars’ landscape by the gradual movement of ice. While surface ice deposits are mostly limited to Mars’ polar caps, these patterns appear in many non-polar Martian regions. …read more […] NASA’s Psyche mission launched on 13 October 2023 on a journey to explore what could be the exposed metallic core of an ancient planet. …read more […] On a vast ice sheet in Antarctica, scientists and engineers are preparing a NASA experiment called GUSTO to explore the universe on a balloon. GUSTO will launch from the Ross Ice Shelf, near the U.S. National Science Foundation’s McMurdo Station research base, no earlier than Dec. 21. …read more […] The Manhattan Project was a top-secret program that culminated in the development of the first atomic bombs during World War 2. This covert and controversial research endeavor involved many gifted and reputable scientists, including physicist J. Robert Oppenheimer. …read more […] A winter wonderland calls to mind piles of fluffy, glistening snow. But to reach the ground, snowflakes are swept into the turbulent atmosphere, swirling through the air instead of plummeting directly to the ground. …read more […] A vast, flat, “featureless” plain on Mars surprised researchers by revealing a much more tumultuous geologic past than expected, according to a study led by researchers at the University of Arizona. Enormous amounts of lava have erupted from numerous fissures as recently as 1 million years ago, blanketing an area almost as large as Alaska and interacting with water in and under the surface, resulting in large flood events that carved out deep channels. …read more […] In quantum mechanics, particles can exist in multiple states at the same time, defying the logic of everyday experiences. This property, known as quantum superposition, is the basis for emerging quantum technologies that promise to transform computing, communication, and sensing. But quantum superpositions face a significant challenge: quantum decoherence. During this process, the delicate superposition of quantum states breaks down when interacting with its surrounding environment. …read more […] 
 Even though the Apollo missions brought back to Earth huge amounts of data about the moon, it has remained an enigma for astronomers and scientists alike. Dr. Robert Jastrow, the first president of NASA’s Commission of Lunar Exploration called the moon “the Rosetta Stone of the planets.” But what is it about the moon that fascinates everyone? Well, there are many people who firmly believe that Earth’s moon is actually a terraformed and engineered piece of hardware that has a 3-mile thick outer layer of dust and rocks. Beneath this layer, it is believed that the moon has a solid shell of …read more […] |
