At ~5:02 pm CDT on August 27 2019, SpaceX successfully launched its Starhopper test vehicle on a 150-meter flight test. After ascending to 150-meters, Starhopper successfully landed at a landing pad ~160-meters away.

The 150-meter flight was the last of a long line of tests that Starhopper, the first vehicle in the Starship program, conducted. It was based on the Big Falcon Rocket (BFR, a previous name for Starship)2018design. Starhopper used a single Raptor engine and three non-retractable legs.

On August 9 2021, the joint ESA/NASA Solar Orbiter spacecraft performed a flyby of Venus, coming within 7,995 km of the Venusian surface. Just 33 hours later, on August 10 the joint ESA/JAXA BepiColombo spacecraft flew by the planet, coming within 552 km of the surface.

The historic double flyby was a result of the two spacecraft attempting to reduce their orbital energy while en route to their respective destinations. BepiColombo is traveling to Mercury, where it will study the planet in-depth, while Solar Orbiter is finishing its last flybys before entering the correct orbital inclination to best observe the Sun.

NASA’s MOXIE could make breathing in Mars a reality. The space agency’s new invention can turn Martian air into oxygen, making it a game-changer for future Mars explorations.

According to Popular Mechanics’ latest report, it is impossible to breathe on Mars since its atmosphere is around 1% the density of Earth’s. Will this be beneficial for Elon Musk’s planned ‘Mars City?’. NASA’s MOXIE experiment will soon have an answer for us to thrive longer on the red planet. This weekend, the space agency hopes that the automated system could be the saving grace for humans to live on Mars if a time comes that the Earth becomes unsuitable for living.

The device called Mars Oxygen In-Situ Resource Utilization Experiment could supply humans with oxygen through extracting from the atmosphere of the red planet which is composed of 96% of carbon dioxide. The process will be made possible through electrolysis which involves the device being run through an electrical current. Since the Perseverance rover’s touchdown in February, MOXIE will conduct the third oxygen-extraction procedure. Moreover, what it produces could supply enough oxygen for humans that is good for 10 to 15 minutes.

The unambiguous discovery of a Wigner crystal relied on a novel technique for probing the insides of complex materials.

“The network learned to find fundamental concepts that are key to molecular structure formation, but without explicitly being told to,” Townshend added. “The exciting aspect is that the algorithm has clearly recovered things that we knew were important, but it has also recovered characteristics that we didn’t know about before.”

Having shown success with proteins, the researchers turned their attention to RNA molecules. The researchers tested their algorithm in a series of “RNA Puzzles” from a longstanding competition in their field, and in every case, the tool outperformed all the other puzzle participants and did so without being designed specifically for RNA structures.

“We introduce a machine learning approach that enables identification of accurate structural models without assumptions about their defining characteristics, despite being trained with only 18 known RNA structures,” the authors of the Science article wrote. “The resulting scoring function, the Atomic Rotationally Equivariant Scorer (ARES), substantially outperforms previous methods and consistently produces the best results in community-wide blind RNA structure prediction challenges.”

The mechanism by which sleep disruption impedes neurodevelopment, however, is still not well understood. It may be that increased wakefulness due to sleep disruption increases glutamate circulation in the brain, affecting glutamatergic structures. Alternatively, decreased REM sleep may reduce “pruning”, an essential developmental process in which superfluous synapses are removed to improve signaling and organization.

The period of neurodevelopment extending from birth to roughly two years of age is one of frenetic, constant change. Neurons and synapses form, are organized, and are pruned. It is well known that sleep plays a fundamental role in these processes, and disruptions to sleep at this stage can be devastating to neurodevelopment and may be the cause of disorders like autism spectrum disorder (ASD).

Understanding the relation between sleep and neurodevelopment in early life is thus essential to understanding (and perhaps preventing) developmental disorders. Building on previous work with prairie voles—a highly social animal with neurodevelopmental similarities to humans—researchers from Portland and California recently published a paper in Current Research in Neurobiology examining the effects of early life sleep disruptions (ELSD) on the prefrontal cortex (PFC).

Researchers have created a scalable quantum computing platform that has been shrunk down to the size of a penny, which would serve as the basis for a quantum computer that can achieve quantum speeds while using far fewer devices than current designs.

The team hopes their research, published in Nature Communications, will help push quantum computing forward in the constant pursuit of use in real-world applications.

Over the past few years, quantum computing has gone from science fiction to a realistic technology that may see use in the next few decades. While quantum teleportation and even quantum computer chips have been demonstrated previously, the technology is still a long way off seeing real-world use.

China has been building the JF-22 hypervelocity wind tunnel in Huairou, an industrial district of Beijing, since 2018. Wind tunnels are large tubes that move air around stationary objects to simulate flying, allowing researchers to learn more about how the object will fly.

The JF-22 will be capable of simulating flying conditions at about 30 times the speed of sound when it is completed in 2022.

November2021will be a big month for NASA.

The Artemis I team is gearing up to launch the spacecraft Orion to the Moon and back for an uncrewed test flight.

At the heart of NASA’s Artemis mission, which aims to land humans on the lunar surface by 2,024 is the spacecraft Orion. Here’s how engineers are preparing for its maiden voyage.
