TASS: Space – the Comet Churyumov

Comet Churyumov-Gerasimenko with the module “Fily” reached the nearest point to the Sun

Apparatus “Rosetta” was launched into space in March 2004 with a spaceport in Kourou to study the comet 67P/ Churyumov-Gerasimenko. To the destination apparatus has arrived in 2014 and is currently in orbit around the comet. November 12, 2014 on the surface of the investigated object was launched module “Fily”. He entered the history of space exploration, as the first probe successfully landing on a comet for the first time and managed to drill the surface for the taking of soil samples. Thanks to this unique scientific mission scientists expect to obtain detailed data about the physical and chemical structure of the comet, which will greatly expand human knowledge about the origin of the Universe.

According to him, the closer to the star in recent months, the comet’s activity has steadily increased. This is evidenced by the comparison of Photographs taken by Rosetta, the robot lander with a difference a year last summer and now. Continue reading

How long to fly to Mars

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

Space when observed with the naked eye

Comets and meteors

Unlike stars and planets that the naked eye perceives as a luminous point, the comet is observed in the form of an elongated spot, in which through careful observation can see the relatively bright concentration – “head” and a conical “tail”. With the aid of the telescope each year find 5-10 comets, but rarely any of them are so bright that accessible to observation with the naked eye. Like planets, comets move around the Sun. But unlike the planetary orbits of the trajectory of comets typically have very elongated. The periods of revolution around the Sun fills the interval from a few years (comet Encke is for 3.28 years) to several thousand years (comet Hale-BOPP – 3000 years).

Comet Hale-BOPP

The comet nucleus, from which emerge jets of gas, plasma and dust all the more intense, the closer to the perfect Sun the comet is a huge (from kilometers to tens of kilometers in diameter) snowball. It is composed of molecules containing hydrogen, oxygen (e.g., H 2 O), carbon and nitrogen, as well as from dust, which escapes as ice sublimation (i.e., in the transition to the gaseous state under the action of radiation of the Sun). In the core there are larger solid particles. Continue reading
