One of the first rumors about the Samsung Galaxy S24 Ultra smartphone tells us that the next flagship of the Korean giant may lose one of the cameras.

The Samsung Galaxy S24 Ultra may not have a 3x zoom telephoto.  But the periscope module will remain

According to well-known insider Ice Universe, the Galaxy S23 Ultra can only get one camera – based on the periscope module. But the usual “telephoto” with a three-fold zoom may disappear.

What approximation the periscope module will provide in this case is unclear. Now, we recall, the Samsung flagship is one of the most versatile smartphones in terms of the capabilities of its cameras, as it has a conventional camera with a three-fold optical zoom, and a periscope camera with a 10-fold. Perhaps the changes in the S24 Ultra will be due to the use of a periscope module with a variable focal length. Or the 3x zoom will be replaced by a crop from the main camera, as is done on the iPhone with a 2x zoom.

Ice Universe was the first to accurately talk about the new trend of smartphones with waterfall screens, the notch in the iPhone X, the new design of the iPhone 14 and Samsung’s 200-megapixel image sensor.

Moon flip: Odysseus lander capsized

Moon flip Odysseus lander capsized

Intuitive Machines’ Nova-C lunar lander may have capsized during its descent to the lunar surface on February 22.

Company representatives, speaking at a press conference on February 23, said that according to their information, the lander is on its side at some distance from the intended landing point near the Malapert A crater in the south polar region of the Moon. Intuitive Machines CEO Steve Altemus noted that this could be caused by the module’s overspeed descent, which descended about three times faster than expected.

A few hours after landing, Intuitive Machines announced that the lander was in an upright position. However, as Altemus noted, this information was based on outdated telemetry data.

Engineers have not yet received images from the module, as they are busy setting up radio receivers. Intuitive Machines CTO Tim Crane added that they are also working to determine what data rates they can get if the lander is on its side and some antennas are therefore unusable.

On the side of the lander, facing the surface, there is only one payload – a piece of art created by artist Jeff Koons. Other commercial and scientific payloads, including those provided by NASA, continue to operate and continue to collect data, as they did during the flight to the Moon and during the descent to the surface. One of the science instruments provided by NASA may have saved the mission. Engineers were able to use data from a navigation Doppler lidar developed at NASA Langley Research Center to replace faulty laser rangefinders on the lander.

Problems with laser rangefinders were discovered after the module reached lunar orbit on February 21. Engineers decided to use these instruments to more accurately measure the orbit, which turned out to be more elliptical than expected. The lasers, however, did not fire and engineers determined that a physical switch had not been turned on before launch.

“It felt like a blow. We were preparing to lose the mission,” Altemus recalled. Then Crane discovered that it was possible to obtain data from the two lasers of the NASA instrument. This process also ensured that NASA’s payload was more thoroughly tested than originally expected.

The goal of the Nova-C payload was to achieve technology readiness of TRL 6 on a scale of 1 to 9, which involves testing a prototype technology in an appropriate environment. The TRL (Technology Readiness Level) is a technique used to assess the degree of readiness of a technology for industrial use. Due to the successful use of this technology during landing, engineers have established a TRL level of 9, which means that the technology has passed all the necessary tests and is successfully used in an industrial environment.

Altemus added that the fact that the Nova-C lander ended up in an elliptical orbit was an “accident” that prompted engineers to activate the laser rangefinder earlier than planned and detect the problem. “It was luck and a little happy coincidence for us.”

One of the payloads that is not yet operational is EagleCam, a student-developed camera designed to be ejected from the lander about 30 meters from the lunar surface to film the landing process. But the ejection did not occur after the lander’s software was changed to allow the use of navigation Doppler lidar data. The EagleCam is mounted on the side of the module and will be ejected later in the mission, which could remain on the lunar surface for 9 to 10 days, providing images of the lander.

Crane noted that based on the operation of the optical navigation sensors on the lander, it is likely that the module is within two to three kilometers of the planned landing site. NASA’s Lunar Reconnaissance Orbiter is scheduled to fly over the area in the coming days and take images to determine the exact landing site.

Researchers were able to synthesize 5 rare isotopes on Earth. Understanding the origin of heavy elements in the Universe reaches a new level

1708786025 Researchers were able to synthesize 5 rare isotopes on Earth

The research at the Facility for Rare Isotopes (FRIB) at Michigan State University synthesized five new isotopes: thulium-182, thulium-183, ytterbium-186, ytterbium-187 and lutetium-190. This is the first time that scientists have managed to obtain these isotopes on Earth; they have not been found on our planet before.

Mergers of ultra-dense neutron stars are considered one of the possible scenarios for the formation of heavy elements such as gold and silver. This study brought scientists closer to understanding the processes that occur during such fusions and the formation of heavy elements.

Stars can be considered as nuclear furnaces in which the synthesis of elements from hydrogen to iron occurs. However, to create elements heavier than iron, a special condition is required – the collision of neutron stars.

At the end of the life cycle of massive stars, their iron cores remain, which cannot synthesize heavy elements. The energy that kept these stars from collapsing due to their own gravitational influence is running out. This leads to nuclear collapse and supernova explosions. However, this collapse can be stopped when electrons and protons become a sea of ​​neutrons, which are prevented from merging by an aspect of quantum physics called “degeneracy.” This degeneracy pressure can be overcome if the star’s core has sufficient mass, resulting in the collapse and “birth” of a black hole. But sometimes the initial mass is not enough and the stars “regenerate” into neutron stars.

Moreover, it is not the end of nuclear fusion if the neutron star exists in a binary system with another massive star that also eventually “degenerates” into a neutron star.

These super-dense stars, with masses one to two times greater than the Sun, orbit each other in narrow orbits and emit gravitational waves. Gravitational waves carry away angular momentum from the system, causing the neutron stars to move closer together and emit gravitational waves with greater intensity. This continues until they eventually merge with each other.

Given the extreme nature of the process, neutron star collisions in such binary systems create an extremely aggressive environment. For example, this event releases a substance rich in neutrons. This substance is believed to be important for the synthesis of gold and other heavy elements. Free neutrons can be captured by other atomic nuclei. These atomic nuclei then become heavier, giving rise to superheavy unstable isotopes. These unstable isotopes eventually decay into stable elements such as gold, which are lighter than superheavy elements but heavier than iron.

If scientists could recreate the superheavy elements involved in this process, they could better understand the process of creating gold and other heavy elements. The synthesis of five new isotopes – thulium-182, thulium-183, ytterbium-186, ytterbium-187 and lutetium-190 – allows scientists to recreate the conditions under which heavy elements are formed. They are created by bombarding the dam with platinum ions in FRIB. While it is likely that these particular isotopes are not present in neutron star debris, their creation on Earth is a step toward creating transitional superheavy elements that can later decay into stable elements, including gold.

Mercedes-Benz plans to diversify its electric strategy: hybrids and electric vehicles will account for only half of sales until 2030

Mercedes Benz plans to diversify its electric strategy hybrids and electric

Mercedes-Benz is the latest automaker to scale back its electric vehicle ambitions. In 2021, the company published an electrification plan that would see it sell only battery-electric vehicles from 2030, at least in countries with suitable infrastructure. On February 22, Mercedes presented its annual results for 2023, from which it became clear that the company doubts that markets will be ready to accept only electric vehicles by that date.

Mercedes isn’t abandoning electric vehicles, but now says it expects electrified vehicles, including hybrids and battery-electric vehicles, to account for half of all sales in the second half of this decade. The company said it is taking the necessary steps to transition to an all-electric model, but also aims to meet different customer needs by offering options with an all-electric powertrain or electrified internal combustion engines until at least the 2030s.

This change has long been discussed in Mercedes conference rooms. CEO Ola Källenius warned in September 2022 that even Europe would not be ready for an all-electric lineup by 2030.

For electric vehicle fans, this is yet another example of corporate response to declining consumer demand. It is believed that electric vehicles have become one of the new technologies that go through a cycle of hype, first generating high expectations and then disappointment.

Global electric vehicle sales grew 31% in 2023, but that’s half the growth rate achieved in 2022. In the US, automakers such as Ford and General Motors have already admitted that their electric vehicle plans were too ambitious or did not target the right market segments, such as full-size pickup trucks. Even startups like Rivian and Lucid are projecting significant production cuts in 2024.

Car dealers who are skeptical of electric vehicles could be blamed for this. They, receiving record profits, complain that they have to master new technology. But one of the reasons many consumers don’t feel confident buying electric vehicles is discomfort. An electric vehicle owner who can charge at home knows that he will wake up every morning with a fully charged battery, but this contrasts with the need for weekly or more frequent visits to gas stations. In addition, drivers are accustomed to fast refueling, which is problematic for electric vehicles even with fast charging.

Electric vehicles also remain more expensive compared to internal combustion engine vehicles. This is due to the high cost of lithium-ion batteries. Once the price of batteries drops below $100 per kWh, the cost of electric vehicles could become comparable to the price of cars with internal combustion engines.

Battery prices are gradually falling, but not fast enough. In November, BloombergNEF published a study that showed battery prices fell 14% year-on-year, but at more than $130 per kWh, it’s clear why electric vehicles still cost thousands of dollars more than their gas-powered counterparts.

Instead, we can expect more adoption of hybrid electric vehicles and PHEVs (plug-in hybrids). Hybrid vehicles provide a cost-effective alternative to simply burning liquid hydrocarbons and help reduce carbon dioxide emissions.
