NASA plans to build a repair station in orbit

12.12.2016

The American space agency NASA plans to entrust the maintenance of orbital stations and spacecraft to the Restore-L automatic satellite, which will be able to refuel and repair them.

So, the device will receive a navigation system and robotic arms, which are controlled by special software. He is able to capture satellites and return them to their proper place after service work.

The first tests of the system will take place in 2020, when the robot will try to refuel another device in orbit.

In the future, Restore-L will be used to monitor space debris and test an asteroid delivery system to the Moon. The maintenance program will also extend the life of the satellites.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

First steam-powered rocket 11.01.2019

An amazing spaceship that never runs out of fuel is ready to revolutionize space exploration.

A project called World Is Not Enough (abbr. WINE) solved the problem of lack of fuel for long-haul flights. Instead of using fuel from an auxiliary tank, it simply extracts water from the environment and turns it into steam. Yes, yes, a steam space rocket, just like in Jules Verne's novels, is not fiction, but reality.

"This technology can be used to get to the Moon, Ceres, Europa, Titan, Pluto, asteroids - anywhere in space where there is enough water and optimally low gravity," says Phil Metzger, a researcher at the University of Central Florida.

With NASA money, Honeybee Robotics has already built the first microwave-sized prototype space steam engine. Metzger performed the basic calculations using computer simulations, and when it came time to test the WINE prototype, UCF provided him with materials that mimic the astroid - in order to test as close as possible to real conditions whether the ship could drill through the ice.

According to Metzger himself in a press release, the launch was successful. "WINE successfully drilled through ice in a vacuum, turned it into rocket fuel and took off on a jet of steam." His invention may indeed be the solution to the problem of long-distance space travel. Astronomers have already established that many planets, their moons (including our own) and asteroids have a lot of water - however, all of it is in a frozen state. But where will the machine get the energy to start drilling? The inventors have foreseen this too: WINE also has a solar panel that can generate enough energy to drill and turn ice into steam.

And, of course, one of the most important advantages of such a strategy is its cheapness. A steam engine costs an order of magnitude less than a rocket engine, while it can receive fuel virtually free of charge and in an almost unlimited amount.
