Pixxel plans to form a constellation of small satellites for hyperspectral imaging of the earth’s surface with the highest resolution

Pixxel, which calls itself “the new leader in advanced Earth imaging technology,” has announced the completion of an initial round of funding that raised $ 7.3 million. Omnivore VC, Techstars and other companies were the new investors. who have joined Lightspeed Ventures, Blume, growX and other investors who have believed in Pixxel’s future.

In addition, Pixxel, founded in 2019, has come out of stealth today and publicly announced its goal of creating the world’s highest resolution hyperspectral satellite constellation.

“We’re thrilled to finally share what we’re building at Pixxel. The new funding allows us to create a planetary health monitor using state-of-the-art hyperspectral small satellites. It will enable us to achieve some of the most complete images of its kind, ”said Awais Ahmed, co-founder and CEO of Pixxel. “These hyperspectral satellites will enable society to tackle many of humankind’s most pressing problems, and we believe they will become the holy grail of remote sensing, providing the best combination of spatial, temporal and spectral resolution available today, and enabling people to see the Earth like never before.” …

Pixxel satellites for hyperspectral imaging of the Earth can transmit 50 times more information than conventional multispectral satellites in widespread use today. They work with a large number of spectral bands (300, including visible and infrared), collecting accurate chemical signatures and “offering more accurate solutions to previously unsolved problems” in industries such as agriculture, energy and environmental protection. Once deployed, the Pixxel constellation is said to provide 24/7 global coverage at a higher resolution and at a lower cost than any existing satellite competitors.

The first Pixxel hyperspectral satellite will be launched in the next few months.

Elon Musk told why to chip people

Elon Musk wrote an article for the Chinese magazine China Cyberspace, which is published by China’s Internet censorship agency. In the text, he, among other things, told why people need to be chipped – this will be done by his company Neuralink. The translation of the article was published by Yang Liu, a correspondent for the Chinese state agency Xinhua, on his blog on Substack.

Elon Musk told why to chip people

Neuralink is focused on developing computer-human brain fusion technologies, developing coin-sized brain chips similar to wearable devices such as smartphones.”, — wrote the billionaire.

According to the businessman, chips from Nueralink are planned to be deeply integrated with the user’s body. “[Чипы] register and stimulate brain activity using implants in the cerebral cortex” Musk added.

He also recalled that the chip will help people with disabilities – restore the motor function of limbs in people with spinal injuries and nervous system disorders, and also allow paralyzed people to use their brains to work with computers and smartphones.

Musk concluded that the technologies of his companies Tesla, SpaceX and Neuralink together will be able to “help achieve a better future for humanity“.

James Webb Space Telescope Captures Imposter

The James Webb Space Telescope sent images in which astronomers noticed the ancient galaxy CEERS-DSFG-1, which was previously considered a record holder, which appeared just 200-300 billion years after the Big Bang. However, the work of two groups of astrophysicists disproved this.

James Webb Space Telescope Captures 'Imposter Galaxy'

The farther away a galaxy is, the earlier in the universe it can be seen and the more its light is stretched due to the expansion of the universe, causing blue and ultraviolet light from hot young stars to appear infrared. Astronomers call this effect “redshift,” and the greater the redshift, the farther and older the galaxy.

A team of astronomers from the National Astronomical Observatory of Japan used the NOEMA (Northern Extended Millimeter Array) submillimeter telescope in France to discover this distant galaxy. As a result, scientists have found that it contains a huge amount of dust.

The dust absorbs the blue waves of starlight while letting through the red waves. This means that a dusty galaxy can mimic high redshift galaxies. Taking this into account, the team calculated that CEERS-DSFG-1 formed just 12.5 billion years ago.

Additional evidence for this theory was provided by a team of astronomers from the Harvard Center for Astrophysics. They also concluded that CEERS-DSFG-1 mimics the record-breaking galaxy. They also found that all of the nearest neighbors of CEERS-DSFG-1 are a young protocluster of galaxies, and CEERS-DSFG-1 is at the center of this cluster.

12228 stream processors 384 bit memory bus and 192MB fast cache

Another portion of preliminary details about AMD’s new generation 3D cards has been published on the Web.

12,228 stream processors, 384-bit memory bus, and 192MB fast cache.  Possible characteristics of the Radeon RX 7900 XT

It is assumed that the Radeon RX 7900 XT will be built on the Navi 31 GPU, consisting of one GCD module (the equivalent of CCD in Ryzen processors) with 12,288 stream processors and six MCD modules – each with 16 MB of third-level cache (Infinity Cache) and 64 -bit memory controller. In total, this gives 96 MB of cache memory and a 384-bit bus, but the use of bulk packaging technology will allow each MCD to place another cache chip, as a result, the total volume of Infinity Cahce will be 192 MB.

This is the full Navi 31 configuration, but there will also be a stripped-down version – with 10,752 stream processors and five MCDs – with 160 MB of Infinity Cache and a 320-bit bus. Such a GPU could form the basis of the Radeon RX 7800 XT.

Navi 32 is another contender for the Radeon RX 7800 XT (or more likely the Radeon RX 7800). It predicts the presence of 7680 stream processors, a 256-bit bus and 64 MB of Infinity Cache (there will be no additional cache memory chips). Finally, the Radeon RX 7700 XT can get a monolithic Navi 33 GPU with 4096 stream processors and 32 MB Infinity Cahce and a 128-bit bus.
