Recent study Enceladus, one of Saturn’s months, revealed several organic compounds that have never been recorded before. The findings were published this month in the astronomy of nature, provide new marks on the inner chemical composition of this icy world, as well as a new hope that you could pound life.

The researchers analyzed data from the Cassini probe, which appeared in 1997. and studied Saturn and his moon to his destruction in 2017. year, Cassini collected data from the icy fragments from the Moon’s underground ocean into space.

Enceladus has been discovered in Saturn’s gravitational withdrawal by 274. It measures a diameter about 500 kilometers, which makes it a planet six-largest satellite. Although this month does not expire for its size, it is significant for its cryonolcanoes on Encladus South Pole, which has expelled water vapor and ice fragments. The plumps of expelled material can be expanded to almost 10,000 kilometers in length, which is more than a distance from Mexico to Patagonia, and some of this material rises into space. The farthest saturn’s main rings – his ring – primarily seems of ice thrown in the enceladus space.

It is believed that this material comes from the saline water chamber below the moon iceberg that is associated with its rocky core. It is possible that chemical reactions take place down, under high pressure and warm.

So far, most chemical analysis of ice from Enceladus was deposited in Saturn’s E ring. But during the fast flying month in 2008. Cassini was sufficient enough to sample freshly thrown fragments from Kriovolcan. New research work reaffirmed this data, confirming the presence of previously discovered organic molecules, as well as the detection of compounds previously undetected.

“Such compounds are of the intermediaries in the synthesis of more complex molecules, which could be potentially biologically relevant. However, these molecules,” Nozair Khawaja, the planetary scientist from Berlin and the leading author of the study, said for Reuters. The discovery significantly expands the range of confirmed organic molecules on encepladus.

The key is that the compounds appeared in freshly thrown particles, suggesting that they were formed within the moon-hidden ocean or in contact with their internal interfaces, not during travel via e-ring or exposure. This increases the hypothesis that the hydrothermal processes below the enSpoladus surface could generate rich organic chemistry. By combining this new research with previous studies, scientists have now found five out of six elements that are necessary for life-carbon, hydrogen, nitrogen, oxygen, phosphorus and sulfur disincludes satellite material.

Sam alone is not the discovery of life, nor biosignatures – signs of life. However, the research confirms that Enceladus has three basic conditions for life in the form: liquid water, energy source and essential elements and bodies. “Enceladus is, and it should be ranked, as the main target for researching residence and search whether there is life or not,” Khawaja said.

“In your rush to move fast, they add long-term collision hazards,” McKnight said.

Deputy Chief of the Chinese National Space Agency, Bian Zhigang addressed the International Astronautical Congress on Monday. They asked him about the commitment of China to good management space management. Bian admitted a “very serious challenge” in this area, “especially with megaconstelles.” He did not mention the Chinese problem with the leaving rockets in the orbit.

White said China “is currently exploring” how to remove spatial debris from the orbit. One of the mission China claims is to test the techniques of relief for dismissal attached to multiple space boat in orbit, but American officials see it as a military threat. The same basic technologies needed to clean the space for cleaning space, Rendezvous and connecting systems, robotic weapons and automation on board – can be used to laminate the opponents satellite.

Silver lining

McKnight and its co-authors (from the US, Great Britain, Italy, Japan and Russia) went an extra mile to assess the threat of changing the difference to rejecting some of the most dangerous items from the list. He said the results were promising.

“If you take 10 objects, you reduce it by 30 percent,” McKnight said. “It’s a measurable change. I think that’s what’s missing in the past about the justification of active debris.”

Active debris removal is an elusive proposal. Although technically feasible, because several missions showed, there is a question of who pays. Is there a sustainable market for cleaning the space cleaning services? The European Space Agency and the Japanese Space Agency has invested a low level of funding in the debris removal initiatives. One of these projects, led by the Japanese company named Astroscale last year, completed a successful demonstration to set the phase for the future attempt to agree with the defective Japanese rocket and directs him into the atmosphere.

Astroscale was founded in 2013. for the purpose of displacing the low-time orbite of space trash. Realization of a limited market for these missions, the company turned back and back in the continuation of the satellite service and filling fuel technology.

“We can make a measurable impact on the potential that creates debris and potential to start Kessler syndrome by removing 10 or 20 objects,” McKnight said. “The bad news is that we just added 26 new facilities in the last two years.”

Gravitational Lean not only separates the light source, but increases it, allowing a detailed display of light sources behind the lens. Thanks to that, the team says the HER-3 Galaxy’s bright star of the Galaxy that was subjected to the star explosive center – and was formed at the time when the stars formed at the peak. HERS-3 also has a sloping, a rotating disk, from which the gas is removed at an angry rate, says the team.

“Thanks to this natural telescope, we can zoom in in the region 10 times smaller than the Milky Way, and almost 12 billion light years, and in the process concludes the hidden thing in light,” said Hugo Mesias, the co-author of the paper, in the statement.

Giant dark material halo was detected

At first glance, the Einstein’s hers-3 cross seems to be created exclusively by gravitational lenses that generate four giant galaxies located between her 3 and country. However, using a precise model of gravitational lens, the team found that the observed mass of these four giant galaxies is insufficient to explain the schedule of five photos of the cross: their mass is simply not large enough to see the visual effect.

“The only way to play the exceptional configuration we have noticed was to add an invisible, massive component: Halo dark matter in the center of the Galaxy Group,” said the lead author of the Pierre Cox, from the Institute D’Astrophysique de Paris.

NASA Viper Lunar The rover could be delivered to the moon of blue origin, Jeff Bezos’ Aerospace Company. The American Space Agency has awarded the company’s order for the task of designing the delivery plan for the Rover, with the future delivery option.

The award, worth 190 million dollars, is presented through NASA programming local services (CLPS) which the Agency used to buy delivery services to the month from private companies. The award does not imply a direct delivery contract; First, NASA will check if blue origin is able to successfully send expensive Viper Rover to the moon-south pole. To be eligible to download the ribbon, the company must put your blue moon MK1 Munar Lander-Coll with our technology – on the moon surface by the end of 2025. Years.

The blue origin won in this Agreement to send a load to the month of 2023. year, and designed the Blue Mk1 to fulfill it. On this mission, there will be our stereo cameras that will implement surface surveys, in addition to small spheres equipped with laser mission monitoring technology.

“There is an option for delivery and secure rover deployment on the moon surface. The NASA will decide to achieve this option after the execution and examination of the first flight of blue origin from the MK1 Lander,” said the statement.

On the same day, he announced the blue background, “Our second blue moon MK1 Lander has already been in production and in good mk1 Lander, this mission is important for future lunar permanence and they will learn about the origin and distribution of water on the moon.”

Viper-who represents volatile investigating Polar Exploration Rover – they designed NASA scientists to explore the Lunar South Pole for LEDs and other resources of interest. It is about 2.5 meters high, weighs almost 500 kilograms and has a single drill and three scientific instruments. The vehicle was supposed to be launched in 2023. years, just for that date to retire back. Then, faced with growing costs and further delay, 2024. years, Nasa said he canceled the mission. The CLPS reward appears to be the blue origin that revived the program.

The arrival of private space companies has the potential to reduce the traditional costs of the universe, while enabling mission managers to focus on scientific issues. Blue Origin, Firefly Aerospace and Spacex are just some of the companies that have emerged in this sector and won CLPS contracts with NASA.

“NASA is taking the world in research for more months than ever before, and this delivery is only one of the many ways to use the American Lunar area,” the acting administrator said Sean Duffy in the statement. “Our rover will explore the extremely surrounding southern pole, permanently shaded regions to help keep future landing sites and better understanding of people in longer missions, because America leads our future in space.”

Radiant Leonides is the constellation of Leo, which rises around midnight of the local time and is the most in the sky around dawn.

Geminidi (December)

Geminidi are active from 4. December by 17. December, who crossed overnight from 13. December by 14. December. They have a sharp top, so the night is 13. the best time to Skywatch.

Geminidi are the most spectacular meteor shower in the year. In addition to bragging up to 120 or as many as 150 meteors per hour during their top, this meteor shower is also the brightest and most dangerous in the year.

Geminidi is bright, slow moving meteors who often have yellow tones, but can be a number of other colors, including green, blue, white, red or orange. And unlike most meteors, which cause comet debris, Geminid are the rest of the asteroids.

The Night that will be whistling, Gemini’s constellation, will be above the horizon all night and will reach their highest point around 2 in the morning local time, so meteors will be visible for almost all night.

That same night, the moon will be about 32 percent lighted and will increase in the east 1:30 in the east of the USA, so if you watch this shower soon after midnight, the moonlight will not interfere with your viewing experience.

Urside (December)

Urside are active from 17. December by 26. December, cleaning in the early morning on 22. December. This meteor shower is less active than others, usually give about 10 meteors per hour; However, the terms of view will be perfect for Skywatch. The moon will be determined approximately 18:00 in the East of the US, so it will not light up each other in this meteor.

Although Ursidi usually produce the most meteors just before dawn, when its radiant, small dipper (or Ursa is smaller), highest in the sky, you will be able to see meteors throughout the night during the top of this shower. In the northern geographical widths, the whistling Ursida is above the horizon all night.

Showers to look after next year

Quadruple (January)

The four percent occur in December and January and peak during the first week of the year. This meteor shower has a sharp climax, which means that most of his activities occur in the narrower time. Quadrants usually produce many meteors for fireballs – these are, meteors that are very bright-with up to 120 meteors per hour during the shower top.

Number Confirmed planets outside our solar system known as exoplains – rose to 6,000, said NASA. There is a great diversity in these distant worlds, the Space Agency says, with findings, including rocky planets, lion worlds and gas giants that include their stars.

Quite more discoveries is probably on the way. As a result of continuous monitoring of NASA’s Exoplanetic Science Institute (Nexss), more than 8,000 potential planets were identified and awaiting confirmation. It planned with future missions, including Nancy Grace Roman Space Telescope and the worldwide Observatory in the world, the American Space Agency hopes for more planets such as land and worlds with possible signs of life.

Country you A walk today may not be the same planet born before 4.5 billion years ago. Many scientists believe that the country has collided in their infants with another world of Mars, and that instead of being destroyed, it is transformed, which includes the mass of that foreign body to become the planet we know. Recent research adds another layer of relevance to that hypothelicated cosmic event: scientists believe that without that other body, the basic conditions for life on earth may never appear.

The team from the University of Switzerland claims that, due to its proximity, the proto-country that existed before this potential collision lost the volatile elements that are essential to form complex molecules. Every hydrogen, carbon or sulfur, their analysis suggests, evaporates in the first three million years after proto-earth formation. And so the country has evolved without external entries, they say, would probably be the dry world, hosting on the development of complex life.

On the other hand, if the body is formed in the periphery of the solar system – a region that produces heavy waters and other volatile elements – and then hit the rocky planet such as proto-chemical wealth, which is characterized by our planet today, even after the initial aggressive evaporation process. This hypothesis coincides with other proposals that indicate an alien origin of water, according to which icy meteorites bombed the primitive country and put their molecules.

In the studio published in sciences, researchers have precisely measured the radioactive decay of two isotopes, Manganese-53 to Hrom-53, in both terrestrial patterns and meteoretic fragments on Earth. Since these spaceships are formed at the same time as the sun and planets of the solar system, analyzing traces of them and their composition is equivalent to opening a time capsule from the past. By calculating the radioactive decay of Mangan-53, the researchers discovered a point in time when the planets stopped sharing the material with their surroundings and fixed the chemical elements that would retain forever.

Their results show that Proto-Earth sealed its elements only three million years after the birth of the solar system. Moreover, they found that the ratio of the early planet manganese to chromium was very low, suggesting that the proto-earth is an extremely hot world, capable of ejection manganese. Since this element is less volatile than other important elements, such as hydrogen, carbon or sulfur, and you have also avoided.

“Thanks to our results, Proto-Earth was a dry rocky planet in the beginning. It was only a collision with ThEI, and fully brought life,” the first author of the report said in the Unizmetula in the Bern Press Release.

Theia was the name of the hypothetical body that the proto-country passed about 4.5 billion years. Researchers believe that the influence will occur between 30 and 100 million years after the start of the solar system – it is, several tens of millions of years after the ancestor of our planet was a very dry world.

However, the arrival of water and other volatile elements is not equated with the immediate phenomenon of life. Only water does not produce life, but creates a much more favorable chemical and physical environment for other molecules and, with them, biological processes that are substrates. In that sense, Theia set the stage, but did not set fire to the spark.

When the suit did not produce current results, musk gone jingoistiity. A few months earlier, in February 2014. Russia attacked Ukraine, illegally collecting the Crimean Peninsula and launched a global wave of convictions against Moscow. Musk drove that wave in his successful Push that the Congress and Obama administration is to wind a rocket for the signature of the United Lansion Association, Atlas V, because he relied on Russian RD-180 engines. (The suit was eventually settled from the court.) The combination helped to violate the entrance on the movements of the authorities.

Another big jump came in 2017. years. Spacex started using his missile cores again, which dramatically led to the price of giving orbit. (Eight years later, his falcon 9 and the falcon remain the only rockets in their classes in severity with reusable core.) But nothing was more important than the continuous development of Mueller. It became one of the most sought after in the history of aviation, although, as a former employee he told me, “performance-wise, it is terrible.” Its power and efficiency are nothing special. “We did not have the resources to make a lot of design and analysis,” he added. “And so we just tested all the beloved shit from the engine. We are hot for thousands of times. Now they have a motor that is super robust.”

Today, thanks to the part to nine Merlin reusable motors, Falcon 9 can take a kilogram on a low country in orbit for one-third of the previous costs; Falcon heavy, who uses 27 Merlins, falls back again. About 85 percent of the Falcon 9 missions goes into space with previously used first phases. 2022., Spacex jumped from performing about 30 launches a year at more than 60, and last year, 138. NASA’s Launch area and people to explore people are now completely controlled musk. The whole new space economy grew around him, the one who relies on his cheap space to access the network of small spacecraft in a small country. Take the planet laboratories, satellite imagery company. Hundreds of his spacecraft carried Falcon 9.

Indeed, no one is trying to make up for; They just try to find niches in the ecosystem of dominated musk. He is building rockets optimized to reach geostationary orbits, which are further, even what many of his customers follow musk lead and contain their satellite constellations closer to the country. Beginners like a rocket lab and firefly diameter are for their ingenuity. But their current operating missiles are tiny Comparison in a state to transport, most, a few thousand pounds, as opposed to 140,000 for falcones hard.

“Svemirx is the cornerstone in the space industry. And then there is other foundations, such as Firefly. We are very complementary for Spacex,” says Jason Kim, director of Firefly Aerospace. “It’s kind of like air, land and seas. No range – all kinds of transport.” (Kim is not alone in this thinking; Firefly just went to the public in the valuation of $ 8.5 billion; the market cap of rocket laboratories is about $ 21 billion.)

For one thing, the systems imagines that the process data is relatively slow compared to those on the territory. They would constantly bombing them with radiation, and “obsolescence would be a problem” because repairs or upgrades would be confused hard. Hajimiri believes that data centers in space could, one day, be a sustainable solution, but hesitant to say when it can come on that day. “It would definitely be feasible in a few years,” he said. “The question is how effective they would be and how much it would be profitable.”

The idea of ​​simply putting data in the orbit is not limited to emergency networks of technicians or deeper thought of academics. Even some are elected officials in cities in which companies like Amazon hope build data centers to build a point. Tucson, Arizona, Nikki Lee Hall is poetically about his potential during the August’s hearing, in which the Council unanimously voted the proposed data center in his city.

“Many people say data centers don’t belong to the desert,” Lee said. But “if it is really a national priority,” then the focus must be in the “putting dollars and development dollars in the data centers that will exist in the universe. And that may sound wild and a little scientific fiction.”

That is true, but that happens in an experimental level, not industrial. Starting called StarCloud hopes to launch the cooler size satellite several nvidia chips in August, but the launch date is pushed back. Lonestar data systems have landed the miniature data center, transmitting valuable information such as imaginary dragons of the song, on the moon a few months ago, although the land rolled over and died in an attempt. More such startups are planned for the following months. But “it is very difficult to predict how fast this idea will become economically feasible,” said Matthew Weinzierl, an economist from Harvard studying market forces in space. “Space based data centers can also have some niches used, such as processing data based on space and providing opportunities for national security,” he said. “Being a meaningful rival to earth centers, however, will need to compete for costs and services as well as everything else.”

For now, it is much more expensive to put the data center in space than it is putting in, tell, Virginia’s Data Center Valley, where mighty demand could double in the next decade if unregulated. And as long as the stay on Earth remains cheaper, the profit motivated companies will favorize the partial expansion of the data center.

However, there is one factor that could encourage Openai and others to look at the sky: there is not much regulation up. The construction of land data on Earth requires municipal licenses, and companies can be tense local governments whose inhabitants are worried that data development can break their water, raise their planet or overheat your planet. In the universe, there is no appeal neighbors, Michelle Hanlon, a political scientist, and a lawyer leading the Center for Air and Space Law at the University of Mississippi. “If you are an American company looking to put data centers in space, then before it is better, before the congress is like” Oh, we have to regulate it. “
