Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

The threat of space debris to the Earth's magnetic field 01.05.2024

More and more often we hear about an increase in the amount of space debris surrounding our planet. However, it is not only active satellites and spacecraft that contribute to this problem, but also debris from old missions. The growing number of satellites launched by companies like SpaceX creates not only opportunities for the development of the Internet, but also serious threats to space security. Experts are now turning their attention to the potential implications for the Earth's magnetic field. Dr. Jonathan McDowell of the Harvard-Smithsonian Center for Astrophysics emphasizes that companies are rapidly deploying satellite constellations, and the number of satellites could grow to 100 in the next decade. The rapid development of these cosmic armadas of satellites can lead to contamination of the Earth's plasma environment with dangerous debris and a threat to the stability of the magnetosphere. Metal debris from used rockets can disrupt the ionosphere and magnetosphere. Both of these systems play a key role in protecting the atmosphere and maintaining ... >>

Solidification of bulk substances 30.04.2024

There are quite a few mysteries in the world of science, and one of them is the strange behavior of bulk materials. They may behave like a solid but suddenly turn into a flowing liquid. This phenomenon has attracted the attention of many researchers, and we may finally be getting closer to solving this mystery. Imagine sand in an hourglass. It usually flows freely, but in some cases its particles begin to get stuck, turning from a liquid to a solid. This transition has important implications for many areas, from drug production to construction. Researchers from the USA have attempted to describe this phenomenon and come closer to understanding it. In the study, the scientists conducted simulations in the laboratory using data from bags of polystyrene beads. They found that the vibrations within these sets had specific frequencies, meaning that only certain types of vibrations could travel through the material. Received ... >>

100 Mbps for ISS 03.05.2020

A four-year-old project to create satellite systems for high-speed communication between space and ground stations is undergoing field testing. The equipment delivered earlier to the ISS made it possible to establish a downlink laser communication channel with a bandwidth of 100 Mbit/s with the ground station. The developer of technology and equipment was Sony.

Developed by Sony in collaboration with the Japan Aerospace Exploration Agency (JAXA) and the National Institute of Information and Communications Technology (NICT), the communication equipment is based on laser optical disc recording technology. Sony has a wealth of experience in this. By adapting data encoding mechanisms for writing to disk for transmission over an optical (laser) channel, the company was able to help develop the foundations of laser space communications.

Communication equipment was delivered to the ISS in September last year. Then it was mounted on an open Japanese Kibo module. Tests and equipment adjustments were carried out about once a week, when the weather allowed. For the first time, the SOLISS (small optical link for the International Space Station) downlink laser was installed on October 25, 2019. The first bi-directional link using a 1,5 µm laser was installed with a ground station on 5 March. The first HD images from the ISS were received via a laser Ethernet channel on March 11.

A series of experiments with equipment for laser communication will last until June 2020. It is assumed that communication via SOLISS channels will provide real-time transmission of large data arrays both between space stations, which will be required in further lunar and Martian missions, and between spacecraft and ground stations.
