SpaceX Crew Dragon spacecraft successfully returned from the ISS

08.03.2019

The Crew Dragon spacecraft, developed by Elon Musk's SpaceX to deliver and return astronaut crews to the International Space Station (ISS), has successfully splashed down in the Atlantic Ocean after the first Demo-1 test mission. The return and splashdown could be seen on the NASA broadcast.

Crew Dragon undocked from the ISS, after a six-hour flight entered the atmosphere and, braking with the help of four parachutes, splashed down in the Atlantic Ocean about 400 kilometers east of Cape Canaveral.

The first-ever test launch of Crew Dragon took place on March 2 from the Kennedy Space Center in Florida, the next day the ship successfully docked to the ISS. It was a test flight without astronauts. On board the ship was only a humanoid mannequin, nicknamed Ripley.

The NASA-approved Crew Dragon certification program consists of four flight tests: two tests of the crew rescue system (from the launch pad and in flight), as well as two flights to the ISS - uncrewed and manned. Thus, Crew Dragon has already successfully passed the tests of the crew rescue system with an accident simulation at the start, and also successfully completed its first flight without a crew.

At the end of June, Crew Dragon will make another unmanned flight to test the emergency crew evacuation system in flight, and in July, if all goes well, will make its first manned flight with astronauts on board - astronauts Robert Behnken and Douglas Hurley will go on a 15-day expedition to the ISS.

The current contract with NASA requires SpaceX to use a new Crew Dragon capsule every time. At the same time, NASA's contract with Boeing allows you to use the same Starliner ship again. Perhaps in the future, NASA will allow SpaceX to reuse the Crew Dragon, as it did with the cargo version of the Dragon.

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, ... >>

Major risk factor for gambling addiction 07.05.2024

Computer games are becoming an increasingly popular form of entertainment among teenagers, but the associated risk of gaming addiction remains a significant problem. American scientists conducted a study to determine the main factors contributing to this addiction and offer recommendations for its prevention. Over the course of six years, 385 teenagers were followed to find out what factors may predispose them to gambling addiction. The results showed that 90% of study participants were not at risk of addiction, while 10% became gambling addicts. It turned out that the key factor in the onset of gambling addiction is a low level of prosocial behavior. Teenagers with a low level of prosocial behavior do not show interest in the help and support of others, which can lead to a loss of contact with the real world and a deepening dependence on virtual reality offered by computer games. Based on these results, scientists ... >>

Traffic noise delays the growth of chicks 06.05.2024

The sounds that surround us in modern cities are becoming increasingly piercing. However, few people think about how this noise affects the animal world, especially such delicate creatures as chicks that have not yet hatched from their eggs. Recent research is shedding light on this issue, indicating serious consequences for their development and survival. Scientists have found that exposure of zebra diamondback chicks to traffic noise can cause serious disruption to their development. Experiments have shown that noise pollution can significantly delay their hatching, and those chicks that do emerge face a number of health-promoting problems. The researchers also found that the negative effects of noise pollution extend into the adult birds. Reduced chances of reproduction and decreased fertility indicate the long-term effects that traffic noise has on wildlife. The study results highlight the need ... >>

Laser ignition 15.01.2012

Engineers from the Romanian Institute of Laser, Plasma and Radiation Physics and two Japanese companies have created an automotive spark plug using a three-beam ceramic laser. It gives flashes with a duration of 0,8 nanoseconds at a frequency of up to a hundred per second. Three beams cause flashes of a combustible mixture at three points of the cylinder at once.

Laser ignition provides a more complete combustion of the mixture with less harmful emissions. In addition, the electrodes of the candle do not burn - they simply do not exist. While the laser candle is somewhat longer than usual, the developers intend to reduce it.

Toyota has already become interested in the new ignition system.
