Comet Churyumov-Gerasimenko with the module “Fily” reached the nearest point to the Sun
Apparatus “Rosetta” was launched into space in March 2004 with a spaceport in Kourou to study the comet 67P/ Churyumov-Gerasimenko. To the destination apparatus has arrived in 2014 and is currently in orbit around the comet. November 12, 2014 on the surface of the investigated object was launched module “Fily”. He entered the history of space exploration, as the first probe successfully landing on a comet for the first time and managed to drill the surface for the taking of soil samples. Thanks to this unique scientific mission scientists expect to obtain detailed data about the physical and chemical structure of the comet, which will greatly expand human knowledge about the origin of the Universe.
According to him, the closer to the star in recent months, the comet’s activity has steadily increased. This is evidenced by the comparison of Photographs taken by Rosetta, the robot lander with a difference a year last summer and now. Continue reading
Flight to Mars is planned by several countries, who are ready to launch to the red planet manned spacecraft within the next 30 years. However, despite such promising prospects, scholars continue to argue about the feasibility of such a flight.
You should start with the fact that one-way flight will take on a variety of calculations, from 7 to 9 months. Such a long flight is very dangerous as the technical side (increasing the probability of hardware failures) and physiological and also the psychological side. Will the astronauts be so many months in a confined space with very limited contacts? How will it affect the human body for long periods in a weightless condition? How great is the danger of radiation in interplanetary space? All these questions become very relevant in the context of emerging in a not too distant future flight to the red planet.
However, should carefully consider possible consequences and unforeseen circumstances that may confront astronauts involved in such a long expedition. First of all, you should bear in mind that absolutely not possible to interrupt the mission due to any circumstances, or to deliver to Mars new reserves in case of shortage. In this case the crew can only rely on their own strength. Continue reading
While the Solar system in General and Earth in particular is the only house people, we need to know about this house. And what? Humanity is grappling over the years, it would seem, not so complicated questions, and no answers.
1. The Oort Cloud. Does the Oort cloud
The Oort cloud is the biggest mystery of the Solar system. People have never seen this hypothetical plot of the Universe, which, according to theories, is a place of formation of the comets with a long period of treatment. Scientists believe that the Oort cloud is located at a distance from 50 thousand to 100 thousand. E. from our Sun. Its outer boundaries lie on the boundary of the Solar system, and billions of bodies out of the Oort cloud is gravitationally bound to the Sun.
2. The anomaly of the spacecraft “pioneer”. Why probes pioneer deviate from the course?
Space probes “pioneer 10” and “pioneer 11” were launched in 1972 and 1973, respectively, to study the outer limits of the Solar system. NASA scientists have observed significant deviations of vehicles from the course, due probably to the action of gravity of the Sun. When more detailed calculation of the acceleration of the spacecraft found a very weak force of unknown nature, which operated on them. Continue reading
