Astronauts will be sent to the captured asteroids

11.04.2013

Asteroids are one of the smallest space objects, but they have long attracted the attention of the scientific community. Amateur astronomers are trying to find them; professionals study the composition, calculate the trajectory, try to understand their "pedigree". Enthusiast billionaires are even planning attempts to generate super-profits by mining asteroids. But first of all, everyone is interested in the threat of asteroid collisions with the Earth and methods of preventing global and local disasters.

Many hypotheses have been put forward, in what way it is better to change the trajectory of a celestial body or even destroy it. But they all have drawbacks and require careful testing. Surprisingly, however, the possibility of capturing asteroids, transporting them to Earth is being considered. Here, astronauts will be sent to them for a full-scale study of these celestial bodies. Sounds fantastic, but this is exactly the kind of strategy being considered by the National Aerospace Agency NASA.

It should be noted that such plans are in perfect agreement with the long-term plans for the development of the space industry, adopted by the administration of President Obama. According to them, by 2025 the first flights of astronauts to asteroids located at a relatively small distance from the Earth should take place. Then the time will come for a manned flight to Mars.

The study of asteroids in the course of manned missions is not limited to studying the possibility of removing space threats from the Earth. As already mentioned, these space objects are rich in minerals, and their extraction and transportation to Earth is another task to be solved.

So, NASA is currently working on planning a mission to capture asteroids with a robot, deliver it to Earth, and then study it by astronauts. To accomplish this ambitious task, no doubt, it will require the cooperation of a number of large companies, the joint work of research and engineering teams from various countries, the development of new technologies and unique devices. It is possible that the colossal efforts will eventually be justified.

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

Petgugu Global cat litter 15.04.2024

Taking care of pets can often be a challenge, especially when it comes to keeping your home clean. A new interesting solution from the Petgugu Global startup has been presented, which will make life easier for cat owners and help them keep their home perfectly clean and tidy. Startup Petgugu Global has unveiled a unique cat toilet that can automatically flush feces, keeping your home clean and fresh. This innovative device is equipped with various smart sensors that monitor your pet's toilet activity and activate to automatically clean after use. The device connects to the sewer system and ensures efficient waste removal without the need for intervention from the owner. Additionally, the toilet has a large flushable storage capacity, making it ideal for multi-cat households. The Petgugu cat litter bowl is designed for use with water-soluble litters and offers a range of additional ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

Electronic helmet for truck drivers 14.04.2024

Road safety, especially for drivers of heavy construction equipment, is a top priority for engineers and scientists. In light of this, the German Fraunhofer Institute for Structural Strength and System Reliability has introduced a new product - an electronic helmet, which is designed to protect drivers from serious injury when driving construction vehicles. A new electronic helmet developed by a team of engineers from the Fraunhofer Institute opens up new perspectives for the safety of truck and construction equipment drivers. The device is capable of monitoring the level of shaking in the car cabin and warning the driver of possible danger. The basis of the helmet's operation is a built-in piezoelectric sensor, which generates electricity during physical deformation. This mechanism allows the device to respond to intense vibrations typical of construction equipment. When the level of deformation exceeds safe values, an alarm system is activated on the helmet, ... >>

Antivitamins instead of antibiotics 13.04.2024

The problem of bacterial resistance to antibiotics is becoming increasingly serious, posing a threat to the effective treatment of infections. In light of this, researchers are looking for new ways to combat superbugs. One of the promising directions is the use of antivitamins that can have an antibacterial effect. Antivitamins, although known as the opposite of vitamins, have proven to be a promising tool in the fight against bacterial antibiotic resistance. A study conducted by scientists from the University of Göttingen in Germany confirmed their potential in creating new drugs to combat dangerous infections. With the rise of antibiotic-resistant superbugs, there is a need to find alternative treatments. Antivitamins are molecules similar to vitamins, but capable of inhibiting bacterial activity without harm to the human body. At the moment, science knows only three antivitamins: rose ... >>

Power plant on bacteria 02.09.2000

A group of biochemists from the University of Michigan (USA) has assembled a fuel cell that runs on bacteria.

Bacteria, like other living cells, decompose glucose and convert the resulting energy into adenosine triphosphate, the universal energy currency of the cell. In the course of this process, a flow of electrons arises, which activates all the systems of the cell.

Biochemists have introduced molecules into the outer membrane of bacteria that divert part of the electron flow to themselves. A fuel cell fueled by a glucose solution generates a voltage of 0,6 volts at a current of up to 17 milliamps. After some improvement, it is supposed to use such batteries in portable communications equipment.

Meanwhile, in one of the universities in Israel, a method is being developed to divert part of the energy from human cells in a similar way. Then it will be possible to feed with its own electricity, for example, an implanted hearing aid or a heart pacemaker.
