NASA's DAVINCI space probe plunged into the hellish atmosphere of Venus.

last year, NASA has been selected about DAVINCI MISSION As part of their Discovery program. Explore the origin, development and condition[{” attribute=””>Venus in unparalleled detail from near the top of the clouds to the planet’s surface. Venus, the hottest planet in the solar system, has a thick, toxic atmosphere filled with carbon dioxide and an incredible pressure of pressure is 1,350 psi (93 bar) at the surface.

Named after visionary Renaissance artist and scientist Leonardo da Vinci, the DAVINCI mission Deep Atmosphere Venus Investigation of Noble gases, Chemistry, and Imaging will be the first probe to enter the Venus atmosphere since NASA’s Pioneer Venus in 1978 and USSR’s Vega in 1985. It is scheduled to launch in the late 2020s.

Now, in a recently published paper, NASA scientists and engineers give new details about the agency’s Deep Atmosphere Venus Investigation of Noble gases, Chemistry, and Imaging (DAVINCI) mission, which will descend through the layered Venus atmosphere to the surface of the planet in mid-2031. DAVINCI is the first mission to study Venus using both spacecraft flybys and a descent probe.

DAVINCI, a flying analytical chemistry laboratory, will measure critical aspects of Venus’ massive atmosphere-climate system for the first time, many of which have been measurement goals for Venus since the early 1980s. It will also provide the first descent imaging of the mountainous highlands of Venus while mapping their rock composition and surface relief at scales not possible from orbit. The mission supports measurements of undiscovered gases present in small amounts and the deepest atmosphere, including the key ratio of hydrogen isotopes – components of water that help reveal the history of water, either as liquid water oceans or steam within the early atmosphere.

The mission’s Carrier, Relay, and Imaging (CRIS) spacecraft has two instruments on board that will study the planet’s clouds and map mountainous regions as Venus flies overhead, and will also launch a small five-instrument lander that will provide many new measurements. . with very high accuracy descends to the surface of infernal Venus.

“This dataset on chemicals, environments and origins will paint a picture of the layers of Venus’s atmosphere and how they interact with the surface of the Alpha Reggio Mountains, which are twice the size of Texas,” said Jim Garvin, lead author. From a research article in the Journal of Planetary Science and principal investigator DAVINCI at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “These measurements will allow us to assess historical aspects of the atmosphere, as well as detect specific types of rock on the surface, such as granite, as well as look for features in the landscape that can tell us about erosion or other shaping processes.”

DAVINCI will send a probe one meter in diameter to withstand the high temperatures and pressures near the surface of Venus to probe the atmosphere above the clouds near the surface of what could be an ancient continent. In the final kilometers of free fall (artist’s impression shown here), the spacecraft will capture stunning images and chemical measurements of Venus’ deepest atmosphere for the first time.

DAVINCI will use three types of Venus Gravity Assistants, which provide fuel by using the planet’s gravity to change the speed and/or direction of the CRIS flight system. The first two gravity assistants will help prepare CRIS for its ultraviolet and near-infrared remote sensing flyby of Venus, generating more than 60 gigabytes of new atmospheric and surface data. The third Venus gravity assist will create a spacecraft to launch a probe for entry, descent, flag and landing, and for subsequent transmissions back to Earth.

The first flyby of Venus will take place six and a half months after launch, and it will take two years for the spacecraft to be able to re-enter the atmosphere over the Alpha region under perfect “noon” illumination to measure the landscape. Venus Venus at a scale of 328 feet (100 meters) to over a meter. These sensors allow landing-style geological surveys in the mountains of Venus without the need for a landing.

When CRIS is about two days from Venus, the spacecraft’s flight system will launch, along with the three-foot (meter) titanium spacecraft inside it. The probe will begin interacting with the upper atmosphere of Venus at an altitude of 120 kilometers above the surface. The scientific probe will begin scientific observations after the heat shield is removed about 67 kilometers above the surface. With the heat shield removed, the probe inlets could absorb atmospheric gas samples for detailed chemical measurements like those made in[{” attribute=””>Mars with the Curiosity rover. During its hour-long descent to the surface, the probe will also acquire hundreds of images as soon as it emerges under the clouds at around 100,000 feet (30,500 meters) above the local surface.

“The probe will touch-down in the Alpha Regio mountains but is not required to operate once it lands, as all of the required science data will be taken before reaching the surface.” said Stephanie Getty, deputy principal investigator from Goddard. “If we survive the touchdown at about 25 miles per hour (12 meters/second), we could have up to 17-18 minutes of operations on the surface under ideal conditions.”

DAVINCI is tentatively scheduled to launch June 2029 and enter the Venusian atmosphere in June 2031.

“No previous mission within the Venus atmosphere has measured the chemistry or environments at the detail that DAVINCI’s probe can do,” said Garvin. “Furthermore, no previous Venus mission has descended over the tesserae highlands of Venus, and none have conducted descent imaging of the Venus surface. DAVINCI will build on what Huygens probe did at Titan and improve on what previous in situ Venus missions have done, but with 21st century capabilities and sensors.”

NASA Goddard is the principal investigator institution for DAVINCI and will perform project management for the mission, provide science instruments as well as project systems engineering to develop the probe flight system. Goddard also leads the project science support team with an external science team from across the US. Discovery Program class missions like DAVINCI complement NASA’s larger “flagship” planetary science explorations, with the goal of achieving outstanding results by launching more smaller missions using fewer resources and shorter development times. They are managed for NASA’s Planetary Science Division by the Planetary Missions Program Office at Marshall Space Flight Center in Huntsville, Alabama.

Major partners for DAVINCI are Lockheed Martin, Denver, Colorado, The Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland, NASA’s Jet Propulsion Laboratory, Pasadena, California, Malin Space Science Systems, San Diego, California, NASA’s Langley Research Center, Hampton, Virginia, NASA’s Ames Research Center at Moffett Federal Airfield in California’s Silicon Valley, and KinetX, Inc., Tempe, Arizona, as well as the University of Michigan in Ann Arbor.

Realme will prepare for independence from OPPO

Realme has been one of the fastest growing technology companies in the market since its founding in May 2018. This young brand was born under the mighty OPPO, which is why they use a lot of technology required for their products.

However, now we are seeing the first sign that could indicate a separation of the two brands, or at least more independence between Realme and OPPO. This is after the disappearance of goods from the first official OPPO online store in China.

Realme is withdrawing its products from the OPPO Mall in China

According to ITHome, it is no longer possible to find Realme products in OPPO Mall. It is important to note that this is the official online store for Chinese OPPO products, where we can also find several OnePlus products.

Now, if the user follows any link to the Realme section, he will encounter the following message: “This product has been discontinued, we will look for other products.” Note that the tag subsection has also been removed from the application.

However, the official Realme Mall continues to operate and has the brand’s usual portfolio of products. As such, Chinese users now have to head to Realme’s independent store if they want to purchase any of their hardware.

While no reason has been put forward for Realme’s departure from OPPO Mall, the reason seems to be the young brand’s independence. This is the thesis that has received the most agreement among publications related to the technology sector.

This will not be the first time that a sub-brand has parted ways with its founding company after achieving great market success. Take, for example, the Redmi branch, which now operates independently of Xiaomi.

Realme has been one of the fastest growing brands in recent years, even with the pandemic and shrinking smartphone market. Therefore, it is not surprising that the next step will be greater independence from OPPO with its own decision-making structure.

NASA reported on a mysterious rocket that crashed into the Moon behind two craters

NASA photographed the crash site of a mysterious rocket that crashed on the far side of the moon in March, and an unidentified spacecraft left behind a strange double crater that has puzzled scientists.

Pictures of the crash site were taken by NASA’s Lunar Reconnaissance Orbiter (LRO) on May 25. breast June 24. The images show that the lost piece (of which the origin is still disputed) somehow created two overlapping holes when it collided with the other side of the ship. lua Traveling at 5,770 miles per hour (9,290 km/h).
