Comets of the Solar system

Comets: the oldest inhabitants of the Solar system

J. L. Lagrange (1813) was also based on firmly established facts – the presence of comets that definitely move in elliptical orbits, including short-period. He explained the origin of comets gigantic volcanic explosions – emissions (eruption) with giant planets. It is, in principle, could explain the nature of the orbits of short-period comets. Subsequently, the views of La Grange shared and developed a number of scientists, among which the most important contribution of the Soviet astronomer S. K. Bo, who worked in this direction with the 20-ies to 80-ies of our century. He has eliminated the biggest internal difficulty is the concept of Lagrange – the necessity of the ejection of cometary masses (nuclei) with the “surface” of the giant planets with their powerful gravity fields, the overcoming of which requires an initial speed of 60 km/s and more. Giant planets also have thick (the length of many thousands of miles) and very dense atmosphere, in the middle of the twentieth century has been very problematic the very existence of a solid surface planets – giants beneath these atmospheres.

Soon everyone will fly into space

Long-standing plans by British billionaire Richard Branson about the organization of space flights is nearing realization. Recently, the head of the Virgin group of companies presented the public with aircraft with a rocket engine called SpaceShipTwo, which will be used for commercial flights into space.

“I know that there are literally thousands wanting to be in space to be able to look out the window, admiring the beautiful Land,” — said the billionaire. At the presentation of SpaceShipTwo in California, he said, dreamed of going into space since then, as seen on TV landing on the moon. Presents the aircraft will undergo tests over the next 18 months, before the first tourists will be able to take a short excursion outside the Earth’s atmosphere. About three hundred people have already applied for the flight is $200 thousand during the six minutes of weightlessness.

SpaceShipTwo, built from lightweight composite materials based on carbon and is equipped with a rocket engine on a hybrid fuel. The basis for its development was the project SpaceShipOne — aircraft, lifting into the air booster. He became the world’s first private space ship and made a series of flights in 2004, reports the BBC . Continue reading
