In a pocket of the universe teeming with galaxies, the James Webb Space Telescope has zeroed in on one blazing so brightly it outshines its stars. The James Webb Space Telescope has spotted the galaxy named GS-NDG-9422 — a realm that existed about one billion years after the Big Bang, and indeed one that may provide the missing link of galaxy evolution between the universe’s first stars and well-structured galaxies. GS-NDG-9422 “will help us understand how the cosmic story began,” Alex Cameron, an observational astronomer at the University of Oxford…

Europe’s Mars ‘fetch rover’ nails sample pick-up test in the field (video)
European aerospace giant Airbus has taken two of its Mars rovers out for field tests in a quarry near London, showcasing for the first time a new robotic arm for autonomous sample collection on alien planets. The company also experimented with a model of its ExoMars rover, hoping to improve its navigation system to enable the robot to travel faster and explore more terrain once it reaches the Red Planet in 2028. During the tests, the Mars Sample Fetch Rover demonstrator model named Codi received coordinates from a simulated ground…
Read MoreNASA’s Europa Clipper on track for Oct. 10 launch to Jupiter’s icy moon despite radiation worries
Three weeks from now, NASA’s Europa Clipper probe will lift off and embark on a long-awaited mission to study Jupiter’s icy moon Europa, which scientists think is one of the most promising places to look for life beyond Earth. The launch appears to still be on track for Oct. 10, as per the agency’s original schedule, which comes as a relief to scientists after the team discovered a few possibly defective transistors just months prior that threatened to imperil the mission. Any signs of life on Europa would likely be…

JAXA (Japan Aerospace Exploration Agency) researchers examined the structures of four titanium-based compounds solidified in levitators in microgravity and on the ground and found that the internal microstructures were generally similar. These results could support development of new materials for use in space manufacturing. To produce glass or metal alloys on Earth, raw materials are placed into a container and heated. But reactions between the container and the materials can cause imperfections. The JAXA Electrostatic Levitation Furnace can levitate, melt, and solidify materials without a container. The facility enables measurement of the thermophysical properties of high…
Read MoreAstronauts 3D-print first metal part while on ISS
ESA scientists have successfully demonstrated 3D printing of a metal part in space for the first time. 3D printing in space poses challenges, as many methods rely on gravity to position materials during the printing process. This is because when creating metal structures, molten metal is often used as part of the filament, or printable medium. In space, its behavior can be unpredictable, which can result in poor-quality objects, as the filament might shift or be placed incorrectly due to the lack of gravitational forces. Scientists therefore had to adapt…

4 Min Read NASA’s Artemis II Crew Uses Iceland Terrain for Lunar Training Credits: NASA/Trevor Graff/Robert Markowitz Black and gray sediment stretches as far as the eye can see. Boulders sit on top of ground devoid of vegetation. Humans appear almost miniature in scale against a swath of shadowy mountains. At first glance, it seems a perfect scene from an excursion on the Moon’s surface … except the people are in hiking gear, not spacesuits. Iceland has served as a lunar stand-in for training NASA astronauts since the days of…

Read MoreNASA’s Voyager 1 probe swaps thrusters in tricky fix as it flies through interstellar space
The distant and cold Voyager 1 spacecraft did a clever thruster trick to help it phone home. Voyager 1, the most distant human object that is now flying through interstellar space, had thruster issues making it difficult for the spacecraft to stay pointed at Earth when calling home. Unless Voyager 1 could make a switch to a different thruster set, the 47-year-old spacecraft would sail on alone without help from Earth. Making matters worse, Voyager 1 is so old that sudden changes could damage the spacecraft. “All the decisions we…
