What are weather satellites used for?

These satellites are located in geostationary orbits, that is, they seem to hang above the surface of the Earth. Every 30 minutes, such a satellite sends to Earth a photograph of the cloudy layer of the atmosphere over a certain area of the surface.

The combination of such photographs gives a complete picture of weather conditions, the movement of cloud masses and cyclones and allows you to make more accurate weather forecasts.

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

The solar wind creates an electrical charge on Phobos 29.10.2017

NASA is considering the Martian moon Phobos as a potential home base for studying Earth from the Red Planet, but powerful solar winds could derail those plans.

A new NASA study shows that the solar wind - a stream of electrically charged particles that "blows" the Sun into space - creates a complex electrical environment on Phobos that could affect astronauts and any scientific equipment that could be carried to the irregularly shaped satellite on future missions. .

Because Phobos has no atmosphere or magnetosphere, it passes directly through the solar wind and absorbs electrically charged particles during the day, leaving a void at night. As a result, negatively charged electrons from the solar wind fill this void and statically charge the satellite.

"We have found that astronauts or rovers could pick up significant electrical charges when passing the night side of Phobos - the side facing Mars during the Martian day. Although these charges are not large enough to harm astronauts, they are sufficient to affect sensitive equipment. " said William Farrell, lead author of the study at the Goddard Space Flight Center.

Theoretically, astronauts could be flown to Phobos, from where they would remotely control robots on the surface of Mars, reducing the significant time delay experienced by operators on Earth.
