They dived to the bottom of hell, under the thick neon-methane atmosphere of Pluto. Flew in the snow storms of ammonia, every second fearing a break in the dark about huge needles durable as steel, water ice. They managed to find an area where there are mountains. The mystery of Pluto has been solved at last — this planet belongs to our Solar system. She captured her during the journey of the Sun through the Galaxy.

SEARCH OF THE WANDERERS
Amateur astronomer William Herschel, discoverer of Uranus
The discovery of Pluto, which for a long time officially considered the ninth planet of the Solar system, has its own history. Before the advent of telescopes humanity were well known five celestial bodies called planets (from the Greek for “Wanderers”, “wandering”): mercury, Venus, Mars, Jupiter, Saturn. During the four following centuries managed to open two more major planets, Uranus and Neptune. Continue reading
Russian scientists in collaboration with foreign partners have classified the threats to the health of astronauts during long expeditions, including during the flight to Mars, said “Interfax-AVN” on Monday, the Deputy Director of the Institute of biomedical problems Russian Academy of Sciences Valery Bogomolov.
“Three years ago, with our international partners, we determined the risk matrix and the degree of our knowledge about these risks, the degree of protection. This list is big enough, it about 15 positions,” said Vladimir Bogomolov, commenting on sending to the ISS first annual expedition consisting of Russian Mikhail Kornienko and American astronaut Scott Kelly.
The annual flight of the astronauts arranged, in particular, in order to prepare future long interplanetary flights.
According to the scientist, it is not only about physiological parameters, for example, about the influence of space flight on the cardiovascular system, the motor area or sensory abilities.
“Takes into account such factors as the adequacy of medical supplies on Board the spacecraft for the relief of disease,” – said V. Bogomolov.
He recalled that the flight, e.g. to Mars and back will take more than 500 days. Continue reading
NASA experts will soon do something that previously could only dream of and fantastic to shoot movies – get inside the comet. If all goes according to plan, tomorrow from the spaceport at Cape Canaveral launched the Deep Impact spacecraft, which will install a copper tube in the path of the comet Tempel 1. It is expected that celestial body will meet 372 kg heavy probe in a milestone for all Americans day – 4 July. After collision at a speed of 37 thousand km/h on the surface of the comet forms a crater the size of a ten-storey house.
The probe (it is a probe, not just RAM) immediately after the collision and the subsequent explosion will take samples of rocks that make up the nucleus of Tempel 1, and cameras mounted on the spacecraft, will take off the “dock” from beginning to end. All the information you plan to transmit it immediately to Deep Impact, located at a safe distance. “We will take the most powerful camera,” said astronomer Michael A’hearn, principal investigator of the project from the University of Michigan. For the clash will be the NASA orbital telescopes. In addition, the orbital meeting, which, according to forecasts, will remind fabulous fireworks will be visible using conventional ground-based telescopes. Continue reading
