Matt Taylor – the adventures of Rosetta
Caught the comet British astrophysicist Matt Taylor told the guests of the festival 360° about the Rosetta mission. about why study comets in General, and about their own role in this Grand project. We have selected a few interesting quotes from Kinot-speech for those who for some reason missed the lecture or watched the broadcast.
About comets in General
I will tell you about their history, about their view on what the Rosetta mission, because I am only a small part of a huge team. So why do we study comets?
This film, created by Polish Studio Platige Image jointly with ESA] was released shortly before docking of the probe Philae from the comet. Its task is to explain the purpose of our mission. We hope to learn more about the evolution of the Solar system – where did we come from? Therefore, it is important to understand how on Earth there was water.
Here’s what we know about comets after all observations. Their Central core is very small if to compare with the “tail” of dust and gas that the comet emits. Continue reading
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
One of the major negative biological factors of outer space, along with gravity, is radiation. But if the situation with the gravity on different bodies in the Solar system (e.g. on the moon or Mars) will be better than the ISS, with radiation, things are more complicated.
On the origin of cosmic radiation is of two types. It consists of galactic cosmic rays (GCR) and heavy positively charged protons emanating from the Sun. These two types of radiation interact with each other. In the period of solar activity, the intensity of galactic rays decreases, and Vice versa. Our planet is protected from solar wind by the magnetic field. In spite of this, some of the charged particles reaches the atmosphere. The result is a phenomenon known as the Aurora Borealis. High-energy GCR almost stopped by the magnetosphere, but they do not reach the Earth’s surface in dangerous quantities due to its dense atmosphere. The orbit of the ISS is above the dense layers of the atmosphere, but inside the radiation belts of the Earth. Because of this, the level of space radiation on the station is much higher than on Earth, but substantially lower than in the open space. Its protective properties of the Earth’s atmosphere pribliziteljny 80-cm layer of lead. Continue reading
