NASA reveals details of DAVINCHI probe mission to Venus

James Garvin from the Goddard Space Flight Center (the name of NASA’s large research laboratory) spoke about the main tasks of the DAVINCHI mission, in which it is planned to launch an automatic probe to Venus in 2029.

NASA reveals details of DAVINCHI probe mission to Venus

The name of the mission stands for Deep Atmosphere Venus Investigation of Noble Gass, Chemistry, and Imaging – “Investigation of noble gases and chemistry of the deep part of the atmosphere of Venus, and imaging.” The flight to Venus will take 6.5 months. After that, the device will make two flybys of the planet, during which the probe will analyze the clouds of Venus and measure the amount of ultraviolet radiation absorbed by the day side of the planet, as well as the amount of heat radiated by the night side. Approximately two years after launch, a landing probe will separate from the main vehicle and descend through the atmosphere of Venus to sample gases on its way to the surface. A probe about a meter in diameter will take about an hour to reach the surface. At an altitude of 30 kilometers, under a layer of opaque clouds, the device will take many photographs.

The DAVINCI probe will have a small inlet on the outside of the high-pressure capsule through which atmospheric samples at various altitudes will be drawn in for analysis. Experts hope to obtain detailed data on each layer of the planet’s atmosphere. After landing in the Alfa Reggio mountains, the device will work for up to 20 minutes, but the main scientific data will be obtained during the descent.

During the mission, scientists hope to obtain at least 60 Gb of compressed new data about the atmosphere of Venus. The DAVINCI team, in particular, hopes to establish whether Venus really had oceans of liquid water in the past, and if so, when and why they disappeared.

US Army tests Microsofts 22 billion augmented reality glasses

The US military has completed intensive testing of Microsoft’s new multifunctional glasses. The soldiers of the 70th Army wore glasses for three weeks, playing three 72-hour scenarios, including movement towards the enemy, attack and defense.

The results of the test report, which will be published in September, will determine whether the US Congress will approve the next $424.2 million test cycle, as well as whether purchases of the device, which is planned to spend another $21.9 billion, will begin. It should be noted that these 22 billion included not only the cost of the glasses themselves, but also spare parts, as well as technical support services for 10 years.

The glasses are a “head display” of the type used by fighter pilots. From a technical point of view, this is a heavily modified version of the HoloLens glasses. The screen of the device, which is always in front of the soldier’s eyes, displays a map of the area, instructions from commanders and other data (for example, an image of a thermal imager).

Elon Musk already has 100 million followers on Twitter A

Despite the fact that Elon Musk has not posted anything on Twitter for a week, his account on this social network is becoming more popular day by day. He recently passed the milestone of 100 million subscribers. To Cristiano Ronaldo, who is in last place in the top 5 most massive Twitter accounts, Musk is only 1.3 million subscribers.

Just over four years ago, at the beginning of 2018, Musk had only 18 million followers on Twitter, and at the time of signing the recent deal to buy Twitter, Musk had 83.6 million followers on the social network. In other words, Ronaldo will not stay in fifth place for long.

It must be said that Musk is used by Twitter not only as a platform for communication, but also for manipulation – very often his messages influenced the quotes of stocks and cryptocurrencies. And you can also remember his tweet about Coca-Cola and cocaine – he became the second most popular in the history of the platform, having collected more than 4.5 million likes.

Is ray tracing now on smartphones Arm introduced the Immortalis G715

Arm has announced a new family of GPUs aimed at the next generation of gaming smartphones. The first solution was a GPU called Immortalis-G715. This is a model that offers hardware accelerated ray tracing. At the same time, it was noted that the G715 will not replace the solutions of the Mali series.

Along with this, the company also introduced two new Mali GPUs with many improvements. For example, they support Variable Rate Shading (VRS) and other technologies, and offer 15% better performance and improved energy efficiency than previous models.

Arm didn’t say much about ray tracing in the Immortalis-G715. So far, no tests or full-fledged comparisons have been presented, so it is not yet possible to assess the quality of work and the number of frames per second. At the same time, ready-made solutions will have to wait until 2023. However, Arm still shared a video that demonstrates the capabilities of the new graphics solution.

Previously, a new super-powerful Cortex-X3 processor core was reported. Less productive solutions were also presented.
