Private companies for flights to the moon

01.06.2019

NASA has selected three private companies that will take care of flights to the moon and deliver equipment to the surface as part of the CLPS (Commercial Lunar Payload Services) project. Delivery of cargo to the moon on a commercial basis is part of the Artemis lunar program, according to the website of the aerospace agency.

For the first phase of the CLPS project, nine companies of various sizes were selected, from startups participating in the Google Lunar XPRIZE competition to large aerospace corporations. The mission of CLPS is to promote the development of lunar landers and commercial lunar delivery services. From among the initial applicants for contracts, NASA had to choose companies that would carry out the full cycle of delivering cargo to the Moon: from launch to landing.

Now the agency has decided on the companies that will receive contracts, and also called the estimated time frame. Astrobotic Technology (the company received $79,5 million) will deliver cargo to the Lake of Death until July 2021, by the same time Intuitive Machines ($77 million) will land the device in the Ocean of Storms, and Orbit Beyond's lander ($97 million) will land on the moon in the Sea of ​​Rains until September 2020.

In February, NASA published a preliminary list of possible lunar experiments, and by the end of the summer of 2019, the agency Head of NASA James Bridenstine noted that scientific instruments will appear on the surface of the moon next year and this will help to send people back to the moon within five years, and on this Since it is planned that one of the astronauts will be a woman.

Before the end of this summer, the agency will decide how to distribute the equipment among the companies that will deliver it to the moon. A NASA press release specifically states that the original nine companies that participated in the first phase of CLPS will also be able to participate in the development of scientific instruments and instruments that will go to the moon.

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, ... >>

Terminator Skin 06.02.2018

Scientists at the University of Colorado have developed a new type of flexible, self-healing and fully recyclable "electronic skin" with applications ranging from robotics and prosthetics to the most advanced biomedical devices.

The skin has built-in sensors to measure pressure, temperature, humidity and air flow, says assistant professor Jinliang Xiao, head of the university's department of chemistry, Wei Zhang. In addition, the development has several distinctive properties, he says. Made from a new type of polymer known as polyimine and coated with silver nanoparticles, it exhibits superior mechanical strength, chemical stability and electrical conductivity.

"What's unique here is that the polyimine chemistry we're using allows the e-leather to self-heal on the one hand, and be completely recycled at room temperature if needed," says Prof Xiao. "With millions of tons of e-waste generated around the world every year, the recyclability of our e-skin is a good economic and environmental solution."

Many people are familiar with the movie The Terminator, in which the film's main villain's skin "heals" seconds after being crushed, smashed, or hit by a bullet, Xiang says. In real life, things look less exciting - healing of cut or broken electronic skin, including sensors, is carried out using a mixture of three commercially available ethanol-based compounds.

Another advantage of the new electronic is that it can be easily used on curved surfaces such as human and robot arms.
