The first South Korean lunar probe sent the first photo of the Earth and the Moon

The Danuri probe, which became South Korea's first lunar probe, sent back to Earth the first image of the Earth and the Moon. Thus, engineers confirmed the functionality of the camera, which examined the far side of the Moon from an unusual distance, according to the website of the Korean Astronomy and Space Science Institute… Continue reading The first South Korean lunar probe sent the first photo of the Earth and the Moon

Spectrometer based on LEGO constructor will make studying physics cheaper

German physics teachers made a universal spectrometer in the Czerny-Turner scheme using LEGO constructors and scrap materials. The authors showed that it can be used to study the spectra of atomic emission, transmission, reflection and fluorescence. Reconfiguring the device for different tasks takes a few minutes, and the total cost of the device does not… Continue reading Spectrometer based on LEGO constructor will make studying physics cheaper

Ozonation of the air caused the skin to create an oxidative field around a person

Chemists from Germany, the USA and Denmark have found that substances secreted by human skin lead to the formation of an oxidative field around it. Scientists placed four people in a sealed mock-up office and began ozonizing the air to a level close to the maximum permissible concentrations. The experiment showed that ozone interacts with… Continue reading Ozonation of the air caused the skin to create an oxidative field around a person

Engineers have learned to touch the touch screen without contact

Engineers from China and Germany have created the GhostTouch device, which allows contactless control of capacitive touch screens, taking advantage of their design features and susceptibility to electromagnetic interference. The device can accurately simulate taps and swipes in different directions on the screens of many popular smartphones without touching them. Despite the fact that the… Continue reading Engineers have learned to touch the touch screen without contact

NASA has fixed a glitch in Voyager 1's telemetry sending system.

The Voyager 1 team solved the problem of sending anomalous telemetry that had been coming from the probe for several months. It turned out that the cause of the failure was a faulty on-board computer, which was mistakenly assigned the operation of sending data. The problem has now been fixed, according to NASA's website. Voyagers… Continue reading NASA has fixed a glitch in Voyager 1's telemetry sending system.

The first launch of the SLS rocket was postponed due to a hydrogen leak

The first flight of the SLS super-heavy launch vehicle carrying the Orion spacecraft was postponed due to problems with a hydrogen leak in one of the rocket's core stage engines. The new launch date is set for September 2, 2022. The first launch attempt was broadcast on YouTube. Artemis 1 is the first flight of… Continue reading The first launch of the SLS rocket was postponed due to a hydrogen leak

Starlink satellites will be able to connect directly to regular smartphones

The new generation of Starlink satellites will allow anyone with a smartphone to connect to the mobile network and the Internet, even from places where there is no terrestrial coverage. The connection speed will be from two to four megabits per second. This was announced by SpaceX CEO Elon Musk and T-Mobile President Mike Sievert.… Continue reading Starlink satellites will be able to connect directly to regular smartphones

Argo AI tested self-driving cars with a bird model on a quadcopter

Argo AI showed off one of the challenges its self-driving cars face during testing at the proving ground. To test how cars react to diving and low-flying birds, engineers decided to hang a bird model on a quadcopter and fly it over the test site at car level. The best way to train a self-driving… Continue reading Argo AI tested self-driving cars with a bird model on a quadcopter

The Swedes showed the superiority of buttons and knobs over touch controls in a car

Drivers spend significantly less time operating vehicle functions, such as changing the radio station or selecting the climate control temperature, when they do so using mechanical buttons and knobs rather than a touchscreen. These are the conclusions reached by the Swedish publication Vi Bil├Ągare, which conducted a study with 12 machines and 4 common tasks.… Continue reading The Swedes showed the superiority of buttons and knobs over touch controls in a car

Americans have developed a clamshell monitor with two screens

The American company Mobile Pixels Inc presented a clamshell monitor: it consists of two separate screens, the angle between which can be adjusted. The monitor project was published on the Kickstarter crowdfunding platform; it has already raised almost $1.7 million. In most cases, people who are not satisfied with one monitor use a combination of… Continue reading Americans have developed a clamshell monitor with two screens
