The planet Mars is one of the brightest objects in our night sky, even visible to the naked eye and resembles a bright red star. About every two years, our planet and Mars is a maximum converging. Such an event in astronomy is called “confrontation”. At this point, Mars will be only fifty-five millions of miles from Earth. People capitalize on that by sending to the Red Planet during the confrontation spaceships. So how much to fly to Mars ?
The orbit of Mars and Earth
The complete journey from Earth to Mars takes between 150 to 300 days to allow for the speed run, the location of the planets and the length of the path, which must pass the spacecraft. In this case the dominant factor is only the amount of fuel. The more fuel, the faster it will take flight.
History of flights to Mars
The first ever space ship, committed trip Earth-Mars, was created by NASA’s Mariner 4. It was launched in late November 1964 and appeared on Mars July 14, 1965. Mariner 4 reached Mars in 228 days. Continue reading
Thanks to the flight to Pluto the earthlings had the opportunity to see a completely unknown distant world, but the planet itself asked scientists puzzle that requires resolution, said in an interview with radio Baltkom, the Russian astronomer who discovered the brightest comet of the decade ISON Artem Novichonok.
“We, first of all NASA employees,as well as all humans, had the opportunity to see a completely unknown distant world located on the outskirts of the solar system and he was totally not as what we expected. This world presents a lot of surprises and much more when the device will reset all data”, – said the scientist.
“First of all we are talking about data relating to the formation of the solar system in General and the formation of those distant objects, one of which is Pluto. Learning of this mission, we see a completely unusual structure, we see that the surface of Pluto and its satellite Charon are very young, suddenly, their bodies are very small, cold, much less the Earth and explain this geological activity is quite young mountains, the age of which children on the part of the solar system is very young, the plains are also very young, completely devoid of craters. All of these processes obyasnite does not work. Continue reading
The universe (cosmos) is a whole world around us, limitless in time and space and infinitely diverse in forms, which takes forever moving matter. The eternity of the Universe in part you can imagine on a clear night with billions of different size luminous shimmering dots in the sky, representing the distant worlds. Rays of light at a speed of 300 000 km/s from the most remote parts of the Universe reach the Earth about 10 billion years.
According to scientists, the universe resulting from Big Bang 17 billion years ago.
It consists of clusters of stars, planets, cosmic dust and other cosmic bodies. These bodies form a system of planets with satellites (for example. Solar system), galaxies, Metagalaxy (accumulation of galaxies).
Galaxy (postdegree. galaktikos – milk, milky, from the Greek gala – milk) — a vast stellar system that consists of many stars, star clusters and associations, gaseous and dust nebulae, as well as individual atoms and particles scattered in space. Continue reading
