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.

Sport in space begins with a football in zero gravity

So, according to the company, Space Island Group, might look like orbiting the stadium. The game tourists in the ball channels could broadcast live .

Weightless — what is not a reason to invent a whole new class of sports? After all, space sports of one type or another, more than likely. Especially due to the rapid development of the private aerospace business and the increased number of space tourists. Is it any wonder that competition in zero-gravity invented today?

If we talk about professional cosmonauts or astronauts, sports games in orbit for them is obvious. Given the fact that in the future the crews of the expand, and the missions will be very long, like missions to the moon or Mars.

A peaceful “battle” with each other under conditions of zero gravity could help space travelers not only to diversify the flight, but also to maintain health, physical and mental. But for space tourists sport in space can be a great added attraction. Continue reading

Space probe approaching Pluto after 9 years

The NASA probe New Horizons close to Pluto and will be able to enter the planet’s atmosphere in July of this year

Span New horizons near Pluto in the artist’s impression of NASA.

The ship, which was launched back in 2006 has come nearer to the outer body at a distance that allows you to make high-quality pictures of its surface.

NASA may have to adjust its trajectory in case of detection of unknown cosmic bodies, reports Russia Today .

Apart from the modern equipment on Board the spacecraft is an urn with the remains of the discoverer of Pluto Clyde Tombaugh (1906-1997), CDs with a message to aliens, U.S. coins, flags and postage stamps. On Board the SPACECRAFT is the CD 434 738 names of people who participated in the campaign NASA “Send your name to Pluto” (Send Your Name to Pluto).

Task apparatus is the study of the atmosphere and the ground layers of Pluto, moreover, New Horizons will create a map of the surface of the farthest planet in our System. Continue reading
