Station Science Top News: September 13, 2024

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…

Astronauts 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…

NASA’s Artemis II Crew Uses Iceland Terrain for Lunar Training

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…

NASA’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…

James Webb Space Telescope zooms in on giant question mark in space (image)

Astronomers often have more questions than answers about the universe — and the universe, in turn, has asked its own question. Quite literally. Last year, the James Webb Space Telescope fortuitously spotted the unmistakable shape of a question mark across the sky. The uncanny feature was captured lurking at the bottom of an image of a pair of forming stars in the Vela constellation roughly 1,470 light-years from Earth. The picture soon went viral on social media sites, prompting a myriad of guesses of its nature, from a sign of…

Hubble Telescope spies a very sparkly mini-galaxy (image)

New images released by NASA’s Hubble Space Telescope are of the Pegasus Dwarf spheroidal galaxy, also known as Andromeda VI.  Pegasus is located in the Andromeda Galaxy, also called Messier 31, which is the Milky Way’s closest neighbour at about 2,480,000 light-years away from Earth. As such, Andromeda is one of the few galaxies visible to the naked eye — best observed in November. The images were captured as part of a re-examination of the entire Andromeda system, meant to gather further information to answer long-standing questions related to dark…
