Startup builds “inflatable” concrete houses in just hours

Posted by in categories: habitats, space

Looking ahead: Automatic Construction is in the process of building a concrete house for one customer in New York and has contracts signed with two others, according to Bell. It’s also inked a deal with a “large commercial contractor” for a structure.

It’s not clear how large those will be, but the prototypes the company has built so far are better described as tiny houses than starter homes — they might be large enough for one person, but they aren’t likely to accommodate a family.

NASA Names Astronauts For First Crewed Moon Mission In Over 50 Years

Posted by in category: space

NASA’s plan to land the first woman and first person of color on the Moon during the first crewed lunar flyby of the 21st century took one giant leap this week with the unveiling of four astronauts for the Artemis II mission.

In a news conference Monday at Ellington Field near NASA’s Johnson Space Center in Houston the space agency announced the first black man, the first woman and the first Canadian on any crewed Moon mission—the agency’s first since Apollo 17 in 1972.

The Apollo 8-style Artemis 2 mission will see NASA astronauts Reid Wiseman, Victor Glove and Christina Hammock Koch, and Canadian astronaut Jeremy Hansen, embark on a 10-day trip around the Moon.

NASA’s Mars Ingenuity helicopter breaks records once again

Posted by in category: space

The off-world chopper flew to its highest altitude and speed on its 49th mission on the Red Planet.

NASA’s record-breaking Mars Ingenuity helicopter has soared to new heights and flown faster. The off-world helicopter has flown for almost two years, massively exceeding its original mission parameters.

On its latest flight, Sunday, April 2, Ingenuity flew to its highest altitude yet and faster than on any of its previous missions. The latest flight.

New AI tool can generate faster, accurate and sharper cosmic images

Posted by in categories: information science, robotics/AI, space

The team was able to produce blur-free, high-resolution images of the universe by incorporating this AI algorithm.

Before reaching ground-based telescopes, cosmic light interacts with the Earth’s atmosphere. That’s why, the majority of advanced ground-based telescopes are located at high altitudes on Earth, where the atmosphere is thinner. The Earth’s changing atmosphere often obscures the view of the universe.

The atmosphere obstructs certain wavelengths as well as distorts the light coming from great distances. This interference may interfere with the accurate construction of space images, which is critical for unraveling the mysteries of the universe. The produced blurry images may obscure the shapes of astronomical objects and cause measurement errors.

AI chip race: Google says its Tensor chips compute faster than Nvidia’s A100

It also says that it has a healthy pipeline for chips in the future.

Search engine giant Google has claimed that the supercomputers it uses to develop its artificial intelligence (AI) models are faster and more energy efficient than Nvidia Corporation’s. While processing power for most companies delving into the AI space comes from Nvidia’s chips, Google uses a custom chip called Tensor Processing Unit (TPU).

Google announced its Tensor chips during the peak of the COVID-19 pandemic when businesses from electronics to automotive faced the pinch of chip shortage.

Mind-Bending Animation Shows How The Universe Would Look if We Could See Gamma Rays

Posted by in categories: energy, space

Most of the light streaming through the Universe is invisible to human eyes. Beyond the mid-range wavelengths we can see, there’s a whole cosmos shining in high-and low-energy radiation.

But we humans are clever little animals and have managed to build instruments that can see the light we cannot. One of these is NASA’s Fermi Gamma-ray Space Telescope, an observatory hanging out in low-Earth orbit, monitoring the sky for gamma rays, the highest-energy light in the Universe.

Fermi constantly surveils the entire sky, observing gamma-ray sources and how they change over time, providing astronomers with a map of the various producers of gamma radiation that we can detect. This data is compiled into a catalog that scientists can use to probe the production of gamma radiation.

NASA names woman, Black astronauts to Artemis II crew in lunar first

Posted by in category: space

April 3 (Reuters) — NASA on Monday named the first woman and the first African American ever assigned as astronauts to a lunar mission, introducing them as part of the four-member team chosen to fly on what would be the first crewed voyage around the moon in more than 50 years.

Christina Koch, 44, an engineer who already holds the record for longest continuous spaceflight by a woman and was part of NASA’s first three all-female spacewalks, was named as a mission specialist for the Artemis II lunar flyby expected as early as next year.

She will be joined by Victor Glover, 46, a U.S. Navy aviator and veteran of four spacewalks who NASA has designated as pilot of Artemis II. He will be the first Black astronaut ever to be sent on a lunar mission.

Recreating the double-slit experiment that proved the wave nature of light in time, instead of space

Posted by in categories: particle physics, quantum physics, space

Imperial physicists have recreated the famous double-slit experiment, which showed light behaving as particles and a wave, in time rather than space.

The experiment relies on that can change their in fractions of a second, which could be used in new technologies or to explore fundamental questions in physics.

The original , performed in 1,801 by Thomas Young at the Royal Institution, showed that light acts as a wave. Further experiments, however, showed that light actually behaves as both a wave and as particles—revealing its .

Physics Breakthrough: Researchers Overcome Long-Standing Limitation of First Law of Thermodynamics

Posted by in categories: physics, space

Physicists at West Virginia University have overcome a long-standing limitation of the first law of thermodynamics.

Paul Cassak, a professor and associate director of the Center for KINETIC Plasma Physics at West Virginia University, and Hasan Barbhuiya, a graduate research assistant in the Department of Physics and Astronomy, are investigating the conversion of energy in superheated plasmas in space. Funded by the National Science Foundation, their findings, published in the Physical Review Letters journal, are set to revolutionize the understanding of how plasmas in space and labs are heated and could have far-reaching implications in physics and other sciences.
