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
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
