Dawn probe will explore the dwarf planet Ceres

11.04.2015

The US National Aeronautics and Space Administration (NASA) has announced the status of the Dawn mission to study the dwarf planet Ceres.

The Dawn probe, launched in September 2007, will be the first spacecraft in history to explore two space objects in the solar system while in their orbits. In 2011-2012 this automatic interplanetary station has already studied the asteroid Vesta, and earlier this year reached its second goal - the planet Ceres, which is located in the asteroid belt.

Currently, Dawn, relying on its engines and the gravity of Ceres, is gradually approaching the dwarf planet to enter a circular orbit. NASA emphasizes that all systems of the apparatus are fully operational, and scientific instruments are ready to perform their tasks.

Now the probe is located approximately 42 thousand km above the surface of Ceres. The main scientific program will begin when the distance is reduced to 13,5 thousand km - reaching this height is scheduled for April 23.

As it descends, the station will send higher and higher resolution images of the planet to Earth. By analyzing them, the researchers hope to unravel the nature of the mysterious bright spots on the surface of the object, which were discovered in February.

On May 9, 2015, the completion of the first phase of the scientific program is scheduled, after which Dawn will move to a lower orbit for further exploration of Ceres.

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, ... >>

Mining platinum on asteroids 19.06.2022

American startup Astroforge wants to become the first company on Earth to master the mining of minerals in space.

The startup, which has just emerged from stealth mode, is working on a technology to extract resources from asteroids with a diameter of 20 meters to 1,5 kilometers, according to TechCrunch. How exactly this system will work is still unknown, but Astroforge promises to demonstrate it in low Earth orbit as early as 2023 and to arrange the supply of minerals from space before the end of this decade.

The startup was founded by two former SpaceX, NASA and Virgin Orbit engineers - Matt Gialich and Jose Acain - and recently completed the Y Combinator acceleration program. Immediately after leaving the business incubator, Astroforge received $13 million in seed investment to develop its project. Entrepreneurs believe that they can solve a problem that has not yet been given to any aerospace company, and in the foreseeable future they will offer humanity an unlimited source of resources. To do this, Astroforge has already enlisted the support of several large organizations.

The startup aims to mine six platinum group metals, including platinum itself (the cost of 1 ton is more than $30 million) and iridium (the cost of 1 ton is more than $196 million). Mining stations will most likely have cargo bays designed for 200 kg or so. The use of much larger volumes for cargo will be inefficient when mining small asteroids with a diameter of 20 meters to 1,5 kilometers. This also means that Astroforge ships will work with objects without any significant gravitational fields.

Astroforge relies on two partner companies: OrbAstro and SpaceX. The first will provide the startup with production facilities for assembling the first devices, and the second will provide space on the Falcon 9 rocket as part of one of the missions scheduled for next year.

Astroforge has also already identified a number of reprocessing candidate asteroids that are in a suitable orbit and have an appropriate concentration of platinum group metals. Of the 10 million asteroids that are relatively easily accessible from the Earth's orbit, according to the startup, about a million can become development objects.

The first space mission involving Astroforge is scheduled for the second half of 2023, with full commercialization by the end of the decade.
