Blue Origin, the U.S. space company of Amazon founder Jeff Bezos, successfully reused and recovered a booster for its New Glenn rocket on Sunday, confirming its mastery of a technical feat that could boost its launch cadence and expand its rivalry with SpaceX. Go to Source The Dark Energy Spectroscopic Instrument (DESI) has successfully completed the largest high-resolution 3D map of the universe ever made, a major milestone in understanding the force driving cosmic expansion. The milestone was reached when DESI’s 5,000 fiber-optic sensors captured their final scheduled observations, targeting a region of sky near the Little Dipper. Go to Source […] Engineers love a good practical challenge, especially when it comes to spaceflight. But there’s one particular challenge facing the crewed missions of the near future that scares mission planners above almost all others—fire. For decades, we’ve relied on a NASA test known as NASA-STD-6001B to screen material flammability for flight. But space is much more […] Our planet rests inside a magnetic cocoon filled with plasma—but it’s not always peaceful and quiet. Activity from the sun can send waves through this space, and some of those disturbances can even reach Earth, affecting our power grid. Go to Source European astronomers have used the Atacama Large Millimeter Array (ALMA) and the James Webb Space Telescope (JWST) to observe a recently discovered giant disk galaxy known as ADF22.1. Results of the new observations, published April 8 on the arXiv preprint server, shed more light on the formation and evolution of this galaxy. Go to Source […] The Artemis II astronauts who ignited a lunar renaissance gave high marks Thursday to their moonship, especially the heat shield, for its performance during reentry. Go to Source Nearly a week after their Pacific splashdown, the astronauts who crewed the Artemis II mission that flew around the moon told reporters Thursday they have yet to fully grasp the magnitude of the moment. Go to Source Texas A&M University is preparing for a new era of space research with the launch of a research centrifuge at the Anthony Wood ’87 Artificial Gravity Lab. Set to become one of the most advanced human centrifuge facilities in the United States, the lab can simulate lunar and Martian gravity for extended periods of time, […] In the era of precision cosmology, research often means big science: large observatories, highly complex instruments, international collaborations and substantial funding. Yet even in such an advanced field, progress is still possible—including in the search for elusive dark matter—through more agile approaches, driven by small teams and young researchers, supported by institutions and a good […] The time had come to open the envelope, but Stephan Schlamminger, a physicist at the National Institute of Standards and Technology (NIST), wasn’t sure he wanted to know the secret number that lay inside. For the past 10 years, Schlamminger had spent most of his working hours trying to measure a single quantity, known as […] The launch of NASA’s James Webb Space Telescope (JWST) in 2021 pushed the horizon of seeing the early universe, unveiling cosmic events just a few hundred million years after the Big Bang. Among the most striking discoveries are supermassive black holes—some reaching 100 million times the mass of our sun. Go to Source […] Interstellar comet 3I/ATLAS is now on its way out of our solar system, never to return. The comet was only the third-ever detected object to originate from outside our solar system. Traveling at high speeds, it looped around the sun within 1.5 AU (one AU, or astronomical unit, is the distance between Earth and the […] University of Birmingham experts have created open-source computer software that helps scientists understand how fast-moving particles behave when they interact with electromagnetic waves in space. Understanding how these particles behave in Earth’s radiation belts is crucial because high-energy electrons can damage satellites, while radiation belt dynamics affect space weather forecasts. Better models help protect astronauts, […] On a chilly yet beautifully clear evening last November, I sat on a video call with colleagues and happened to mention the live feed from the International Space Station—a real-time broadcast from onboard cameras as the station orbits Earth.
