Chinese researchers are preparing to implement innovative robotic systems and platforms to operate the National XNUMXm Aperture Spherical Radio Telescope (FAST), which is nicknamed the "Chinese Sky Eye" and is considered the world's largest single-disk radio telescope.

The joint efforts of the Guizhou Radio Astronomy Observatory and ten other scientific organizations, including the National Astronomical Observatory of the Chinese Academy of Sciences and the Harbin Institute of Technology, are aimed at developing robotic maintenance systems for the telescope.

FAST has an area equivalent to 30 standard football fields, which creates a challenge for its maintenance. The introduction of robotic solutions is aimed at increasing the efficiency of the telescope and increasing the duration of scientific observations.

The main focus is on the development of intelligent robots for testing and maintaining various telescope systems, such as supporting cables and feeders, drives and laser targets on the reflector, as well as monitoring radio interference and meteorological measurements of the feed booth.

Particular importance is attached to the all-weather intelligent robot for measurements in the aft cabin. This device is designed for accurate and reliable measurements in conditions typical of the FAST radio telescope and its surroundings.

The robot, developed by the National Astronomical Observatory, is a unique multifunctional measurement device based on microwave technology designed to operate in the difficult climatic conditions of Guizhou Province.

Another important robot is designed to service laser targets on a reflector. This solution, developed jointly by the National Astronomical Observatory, the Institute of Automation of the Chinese Academy of Sciences and the Guizhou Radio Astronomy Observatory, includes an intelligent device for controlling and maintaining laser targets.

These robotic systems will effectively solve complex maintenance and surveillance tasks that previously faced challenges due to weather conditions and complexity of scale.

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 ... >>

Quantum data protection algorithm 23.11.2023

QuantumCTek Co from China, specializing in quantum information technology, has introduced a new method for ensuring cybersecurity of data in cloud storage. Researchers have used random quantum numbers as encryption keys, increasing the level of data security from quantum computing.

The presented innovative cybersecurity solution based on quantum technologies provides a new level of data protection in the cloud. By using random quantum numbers as encryption keys and applying quantum key distribution (QKD), the system successfully demonstrates quantum security as well as efficiency and fault tolerance. This is an important advance in the field of cybersecurity, which can be extremely useful in the face of the growing threat of cyber attacks and the development of quantum computing.

The basis of the method is the Shamir key distribution algorithm, which allows you to share private information between a certain group of people. This information remains secret until the majority of the group members pool their knowledge.

To improve efficiency and reduce costs, the researchers implemented an additional erasure encoding step within the ciphertext before data transmission using quantum key distribution (QKD). This not only ensures quantum security, but also increases fault tolerance.

The new solution is a practical application of the synthesis of quantum technologies and cryptography, providing quantum key security, guaranteeing the security of user data when uploading it to servers and transmitting data across distributed cloud storage nodes.

The researchers also conducted tests to see if their method could be used not only to transmit data, but also to store it. Experiments including encryption/decryption, key information and data storage confirmed the effectiveness of the new approach.

The solution is technologically and engineering viable, complies with quantum cryptography standards, and provides effective protection against the challenges presented by quantum computing. Given the potential of quantum computers to solve problems orders of magnitude faster than modern computers, the development of a new generation of cybersecurity becomes more than urgent.
