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

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.
The instrumentation of the station includes: two infrared and ultraviolet spectrometers, two additional spectrometer, a small color camera and a telescopic camera with high resolution, the detector plus cosmic dust.
The station configuration includes a 32-bit processor Mongoose, operating at a frequency of 12 MHz. This chip is a close relative MIPS R3000 chip, which was mounted, in particular, in the Sony PlayStation.
Data home the probe will use a very weak communication channel, the bandwidth of which is only 700 bits per second. Time lag when “communication” with the probe is more than 4 hours. According to NACA, to download the whole archive scientist will need more than 9 months.
July 14, 2015 flyby sostolsya system “Pluto — Charon” at a distance of 12 500 km from the surface of Pluto. In General the device will conduct observations only 9 days, which will gather approximately 4.5 gigabytes of information.
In 2016-2020, the device may explores some of the objects in the Kuiper belt. But because of the extremely limited supply of fuel, any trajectory correction after the passage of Pluto will be possible in a very small range (approximately 1 degree), and therefore the selected route depends, will there be an extended portion of the mission. The expected end of the mission – 2026.
Interestingly, the flight from earth to the moon it took the probe 8 hours 35 minutes and took place at a speed of 58 thousand km/h, a record speed for the spacecraft launched toward the moon. But, be aware that the speed of the device (in contrast to missions focused on Earth satellite) is not decreased to reach lunar orbit.
Pluto is on average removed from the Sun at a distance of 5 913 520 000 kilometres (5.9 billion), or 39.5 C and. E.; the Earth is 149 600 000 km (149 million). Making simple calculations we obtain the approximate values:
The average distance from Earth to Pluto: ≈5.7 billion km (≈38.5 C and. E.), the smallest possible distance: ≈4.3 billion km (≈29. E.), the greatest possible distance. ≈7.5 billion km (≈50 a. E.).
The fact that Pluto’s orbit is inclined to the Ecliptic plane (the plane of Earth’s orbit) of 17°, which means that if we want to get the exact value we will not just fold and take away, and apply more complex formulas. Secondly, the Earth and Pluto move at different speeds and complete the circle in their orbits over different periods of time: the Earth is one year, Pluto — 248 years. Therefore, in order to obtain an accurate average value, we have to expect a certain average distance for 248 years, and there is not enough with a simple formula (high + low)/2.
The discovery of Pluto was made February 18, 1930, using images obtained in January of the same year. The name “Pluto” was suggested by the Venice Bernie, 11-year-old English schoolgirl, who until his death (30 April 2009) I lived in England. May 1, 1930, it was officially announced that the planet will be named after Pluto.
