China is planning an ambitious “one stone and two birds” project for the outer planets of Jupiter and Uranus, launching a pair of spacecraft simultaneously with a single rocket around 2030.

The mission is called Tianyuan 4, and the two largest Jupiter-bound probes will be sent to Uranus, while a smaller spacecraft will be sent to explore Uranus.

Launched simultaneously by Changjun 5 rockets, the pair use two flybys of Venus and two flybys of Earth to place the spacecraft on an outer solar system trajectory before determining their intended paths.

China previously said it was in the planning stages of Jupiter exploration, but at the 2022 International Space Conference in Paris on Sept. 21, Wang Qiong of the China National Aeronautics and Space Administration (CNSA) announced the establishment of a new Center for Space Technology and Lunar Exploration. . Details.

The main spacecraft will be designed to study the Jupiter system and eventually enter orbit around Callisto to explore its more distant Galilean moons.

According to the CNSA statement, a small spacecraft weighing a few hundred kilograms will make a long journey to Uranus, indicating that the spacecraft could fly close to the asteroid on its way away from the Sun.

“Scientific targets are still being explored,” CNSA’s Wang Qiong said after the presentation. Previous announcements have focused on extensive surveys of Callisto as the main target, which could reveal much about the history of the Moon and Jupiter, or irregular satellite surveys of Jupiter, which could provide insight into the solar system’s early days.

CNSA had previously considered landers as part of the Carilsto-focused mission profile, but Wang says the latest concept does not include landers other than orbital ones.

Meanwhile, China launched its first independent interplanetary mission in 2020, sending the Tianyuan-1 orbiter and Colony spacecraft to Mars.

Tienwon 2 will launch around 2025 and land on Kamo’oalewa, an underground satellite orbiting the Sun in Earth orbit, collecting samples and returning around 2026.

Tianyuan 3 will be a complex double-launched modular Mars return mission, expected to deliver the first samples collected from Mars to Earth as early as 2028.

Wang also added that with the plan to build an international lunar research base in the 2030s, “the goal is to promote the use of manpower, create a new kind of international cooperation in space exploration, and promote the peaceful use of spacecraft.” space”.

Adobe Fresco is now available in the Microsoft Store

Adobe Fresco is now officially available for download from the Microsoft Store, giving users a new way to access the Adobe digital painting app. Previously, the app was only available through the Adobe website. The store version is still provided and managed by Adobe, which means it is not actually hosted on the Microsoft platform. Either way, it was an easier way to access it.

Adobe Fresco is now available in the Microsoft Store

Fresco is one of Adobe’s most advanced creative tools, a digital drawing and painting application designed primarily for touch devices. It’s actually available on iPad and iPhone, but not on macOS. So it’s really designed for touch screens, even on Windows 11.

According to Adobe, Fresco has the largest and “most advanced selection of brushes” in the world, thousands of which are available in the Adobe Library. The purpose of this app is to mimic real life as much as possible. So when you use watercolor for example, you will see the colors blend in real time. You can also paint in oils and use many other tools to create your desired piece of art. Fresco supports layers, layer masks and other features you would expect from a graphic design tool. Because it’s part of the Adobe Creative Cloud, it’s also linked to assets from Photoshop or Illustrator.

Meanwhile, in addition to being able to share finished work, Fresco has built-in real-time streaming capabilities to make it easier for you to share your knowledge with others. Plus, you can export a time-lapse of your drawing and painting process when you’re done.

However, this version of Fresco lacks support for ARM-based devices such as the Surface Pro 9 with 5G or the Surface Pro X. This is what Adobe originally promised back in 2019 when Surface Pro X arrived. Three years later, he still hasn’t done it. Recently at the Snapdragon Summit, the company confirmed its intention to release an ARM version in 2023, so let’s hope it won’t be long.

xrOS: óculos de realidade aumentada da Apple terão novo sistema operacional

fans Apple waiting for the launch of the headset augmented reality (RA) companies at the beginning of 2023 – in January, to be more precise; however, the change was revealed in an interesting detail. The tech giant announced that the hardware operating system will be called “realityOS‘, however the name will be xroOS, according to the latest reports. The effort invested by the pros has increased in recent months, indicating that the launch of the device is close.

According to recent announcements, Apple’s operating system for the augmented reality headset will be called xrOS.

One suggested reason for the name change is that the “xrOS” designation for international consumers will make it easier to identify the type of content that will be projected with the AR headset. Letters”XR” is an abbreviation for “andXcourted Rreality”, indicating the availability of resources possible with augmented reality, in free translation and interpretation.

Apple’s augmented reality glasses still don’t have a set release date

That is: based on the assumption that the equipment will play mixed content such as RA, as well as virtual reality resources (van), the consumer will be informed about what can be found easily. On the one hand, part of the intended experience is to combine real-time graphical information with the use of the environment and, at the same time, immerse the person in a differentiated experience with aspects of virtual reality, with a headset display.

The equipment will be able to play mixed content, such as AR itself, as well as virtual reality (VR) resources.

Because these approaches require powerful resources to run, despite being portable and lightweight, the hardware must also be powerful. Users will have access to new applications designed to provide unique experiences using product features. A wide range of options is expected, such as cards, messengers adapted for the mentioned technologies and much more.

Unfortunately, while the news was positive for those concerned, sources weren’t able to pinpoint the launch window. Therefore, many expect the presentation to take place in early 2023. Expectations are recommended to be controlled, because this is Apple’s first attempt in the segment, and unforeseen events may occur.

Portugal has been “sending” SMS for 27 years. Peaked in 2012

Portugal has been "sending" SMS for 27 years.  Peaked in 2012

The text messaging service, launched in 1995 in Portugal, peaked in 2012 with over 27 million SMS sent, and according to ANACOM data, that number has dropped to 10 million in 2021.

The world’s first SMS (Short Message Service) was sent 30 years ago, on December 3, 1992, by Briton Neil Papworth, a telecommunications engineer at Sema Group Telecoms, in the United Kingdom.

A Merry Christmas message was sent from Neil Papworth’s computer to Vodafone’s Richard Jarvis’ Orbitel 901 mobile phone.

The historic moment reached a new level in December 2021 when the first 15-character SMS was auctioned off as NFTs (“Non Fungible Tokens” or “Non Fungible Token”) for 107,000 euros during an event hosted by Aguttes in France. .

In Portugal, the messaging service was launched in October 1995 when TMN (currently MEO) and Telecel (currently Vodafone) were in the mobile carrier market, according to data sent to the Lusa Autoridade Nacional de Comunicações (ANACOM) agency.

In October 1995, Telecel first launched the feature for contract services that were not prepaid, a small percentage of the customer base, said Lusa Nuno Taveira, a former product manager for SMS and “messaging” at Vodafone.

One of the turning points in the development of SMS was in February 2000, when an agreement was signed between the three existing operators (after the introduction of Optimus in 1998, now NOS) allowing users to communicate between different networks, the regulator cites.

The first data available in ANACOM refers precisely to the year 2000, when the number of SMS reached 550 million, i.e. about seven SMS per active user per month.

The peak of SMS traffic was reached in 2012, when each effective user sent 180 messages per month, for a total of 27,860,126 messages.

However, according to ANACOM, this number is decreasing. In 2021, 68 SMS were sent per effective user per month (-62% compared to 2012), for a total of 10,729,392.

Another turning point for SMS in Portugal was the introduction of prepaid services, which allowed mobile services to become mainstream, said Lusa Teresa Salema, president of Fundação Portuguesa das Comunicações.

“We must remember that the mobile network first grows in higher segments. It was only after 1995, with the introduction of prepaid services, that we had a greater mass, and at that time, text messages also appeared with greater intensity and reached an absolute level. records,” he said, noting the arrival of the “famous MIMO developed at the time by Portugal Telecom in the laboratories of Aveiro.”

There are now more popular alternative ways to send messages, “instant messaging” such as Whatsapp or Messenger apps available for “smartphones” that combine text with the ability to send images, sounds, documents or popular GIFs.

In 30 years, SMS has had a peak in usage and is now in decline. But its use in advertising and marketing, from a security point of view, as an authentication factor or to create a particular spelling, such as using “k” to mean “it”, is a legacy that continues today.

However, the President of the Portuguese Communications Foundation stated that the technology currently available to the public involves the integration of several factors.

“There are three things that are needed because, in addition to the equipment, access to networks with the bandwidth and speed that we currently have with optical fiber or 5G is needed. And “cloud” (cloud). These are three things that we need to have the services that we have now,” he analyzed.

Teresa Salema, who worked at the Companhia Portuguesa Rádio Marconi in the early 1990s and has a three-decade career in the sector, also defended that technology exists to “improve the quality of life as well as the health of the planet.” .

While there are better ways to send messages these days, Teresa Salema points out that all technology eventually finds its place.

“The fixed network has its own space. And SMS also has its place,” he stressed.

In the case of SMS, its popularity and widespread use via mobile phones ended with another service that had gained relevance earlier: pagers or the “beep-beep” service, he recalled.

“Today, in our museum, we only have what a written message of this type looked like. It was almost like a telegram, so it was even shorter than an SMS.”

In addition, the Fundação Portuguesa das Comunicações, now 25 years old, has a dual mission of “preserving and displaying the entire heritage of the communications sector in Portugal” through the Communications Museum in Lisbon.

Teresa Salema said the history of communication is “much longer” compared to the decade in which SMS was born, and in Portugal it is “five centuries ago, in 1520, with the creation of the postal service”.

“At one time, King D. Manuel created a postal service specifically to support the Portuguese maritime expansion. Because, as is obvious, any economic development is based on a communication network,” he stressed.

The Museum of Communications now has an exhibition to mark its 25th anniversary where you can “touch and experience objects” of old and working technologies such as the typewriter, fax, telex and some GSM equipment, including Nokia co the famous game “Snake”.
