Known in ancient Rome, the largest of all, the planet Jupiter was named after the chief deity of the Romans. Gas giant planet located outside the asteroid belt. Its mass is 2.5 times the mass of all the planets available in our system. Jupiter rotates at a speed of 13 km/s and the time it completes one rotation around its axis passes 9 hours and 55 minutes, and around the Sun planet moves almost 12 earth years.
Jupiter can be observed even in a simple telescope, it emits a white glow and is visible in the night sky, and with him his companions are visible, four of them. Jupiter is a very interesting internal structure. Stone core is surrounded by a metal “frozen” hydrogen, which covers a layer of liquid hydrogen. Jupiter has an atmosphere that consists of hydrogen and helium 99% and 1% of other gases: methane, ethane, water and ammonia. The three main layers in the atmosphere of ice giant form crystals of ammonia, methane and ammonium, water crystals, sometimes in the form of small droplets of liquid that are constantly moving in a vortex, forming a visible telescope in the dark bands.

Most American space programs in recent years have been privatized, and now, the sometimes slow bureaucracy, making stupid things like launching the Shuttle Challenger in very cold weather, when the sealing rings holders solid propellant booster unflexible, corporations aim to make a lot of money.
Last week’s rocket explosion Antares (Tuesday) and “space Spike 2” by “Virgin Galactic” (on Friday) were disasters and, considering the death of one pilot “space Spike” and serious injury of the second, tragedies.
The role of greed here?
Bruce Gagnon, coordinator of the “Global network against the militarisation and nuclear power in space,” said:
“With the privatization of space launch services, the pressure to “cut corners” and save money will be enormous. The idea of launching ships with gullible tourists on Board ships, developed primarily for profit, and least for security – it is scary.” Continue reading
World-renowned cosmonaut training Center in Star city near Moscow, founded in 1960. Legends and equipped with unique equipment, Star city is of great interest to visitors.
Our company offers a variety of programs of tours and excursions in Star city will allow you to see how you train and prepare astronauts to visit the huge pool-the hydro. test your endurance in the human centrifuge training. try on a space suit and try a real “space” food.
In our directory of tours you can find an option excursion to Star city any type – from study tours to multi-day tour with the real elements of the programme of training astronauts.
Excursions to the Star city will be interesting and informative for both adults and children. We offer various options for exciting excursions to the Star city for students.
Flights in zero gravity
Wanted to feel lighter than cotton and is free to float in the air?
You have a chance to realize his dream and visit the artificial conditions of weightlessness, while flying on a special plane-laboratory IL-76 MDK — as do the astronauts, golowasch work in space. Continue reading
NASA: landing on Mars is a large Mars Rover
“Mars Science Laboratory” .
The power supply of the Rover (Rover) “Mars Science Laboratory” will be implemented from plutonium isotope generator. Therefore, the Rover can operate day and night.
In the development of some instruments for this Rover brings together specialists from many countries, including Russia.
Attention! The crew of “Mars-500” on the red planet!
Russian and European space Agency are conducting a joint experiment, simulating the flight of a manned spaceship to Mars and return to Earth.
The project is called “Mars-500” and is based at the Institute of biomedical problems of RAS. The calculations for the project was executed by the Corporation “Energia” S. P. Korolev. Continue reading
Astronomers have determined that comets from the far reaches of our Solar system do not threaten the Earth. The discovery was made after computer modeling of the behavior of these objects. Article researchers appeared in the journal Science . and its summary is contained in the press release of the University of Washington, where the authors of the article.
In their study, the astronomers modeled the penetration into the inner part of the Solar system comets from the Oort cloud – a region whose borders, according to various estimates, are spaced from 2 to 50 thousand astronomical units. The temporal interval was modeled astronomers, was about 1.2 billion years.
Previously, scientists were convinced that the majority of comets with a long period (from 200 to millions of years) period of treatment, currently there are about 3200, with the outer part of the Oort cloud. It was believed that comets from the inner part of the cloud protects the Solar system gravitational field of Saturn and Jupiter, which do not allow these bodies to “annoy” the Earth and other small planets.
