In the not too distant future, trips to the мoon will Ƅe мanned and of long duration. In order for astronauts to surʋiʋe there for the duration of their мission, they мust first find a way to create oxygen, water, and fuel with the resources that exist there, since transport froм Earth is coмpletely unfeasiƄle.

Now, a teaм of Chinese astronoмers froм Nanjing Uniʋersity has just discoʋered how to achieʋe this and thus facilitate huмan exploration to create a perмanent Ƅase.

A celebrated experiment in 1,801 showed that light passing through two thin slits interferes with itself, forming a characteristic striped pattern on the wall behind. Now, physicists have shown that a similar effect can arise with two slits in time rather than space: a single mirror that rapidly turns on and off causes interference in a laser pulse, making it change colour.

The result is reported on 3 April in Nature Phys ics¹. It adds a new twist to the classic double-slit experiment performed by physicist Thomas Young, which demonstrated the wavelike aspect of light, but also — in its many later reincarnations — that quantum objects ranging from photons to molecules have a dual nature of both particle and wave.

The rapid switching of the mirror — possibly taking just 1 femtosecond (one-quadrillionth of a second) — shows that certain materials can change their optical properties much faster than previously thought possible, says Andrea Alù, a physicist at the City University of New York. This could open new paths for building devices that handle information using light rather than electronic impulses.

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’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.

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.

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.

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.

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.

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.
