On Tuesday, the dawn of our time the world’s attention will focus on Jupiter. In the surrounding thick, swirling cloud layer breaks into built by NASA’s Juno probe. Will enter its orbit to a year to take pictures of the solar system’s largest planet.
Powered by solar probe Juno reaches for his five-year voyage – the fifth from the Sun, the largest planet of the solar system, Jupiter – said NASA on its website.
his mission (costing $ 1.1 billion) probe launched in August 2011. on the way, beat nearly 3 billion kilometers.
We have already Jupiter were heard Voyager, Pioneers, Galileo, Ulysses, Cassini and New Horizons, a year ago, in 2015., reached Pluto. Most of them with different objectives, Jupiter passed just over the road. Galileo orbited Jupiter only (or even introduced in its atmosphere probe of measuring apparatus).
NASA decided that Juno will be orbited Jupiter for a year. During this time, has sent back to Earth pictures – the best approximation of the surface of this planet, ever made. Jupiter Images longer pass Although some probes and the Hubble Space Telescope. Researchers say, however, that the best photos will go only into their hands. Juno descends closer to the surface and provide detailed images: the polar regions, clouds or aurora clearing.
In contrast to the rocky Earth or Mars – Jupiter is a gas giant, built primarily of hydrogen and helium. The scientists hope that their research can tell a lot about the fundamental processes of formation and early evolution of the solar system.
When Juno doleci to Jupiter (according to our time will be Tuesday morning), fires the main engine, so that will slow down and enter into orbit around the planet. The precise maneuver will be mission critical, because if the braking was going to fail – Juno distance from Jupiter. Firing the engine will last approx. Half an hour, so that Juno will enter orbit polar planet.
As the message of the radio signal between Jupiter and the Earth takes 48 minutes, in case of problems mission controllers at Jet Propulsion Laboratory (NASA) California will not be able to intervene on a regular basis. They can only wait and listen for signals suggesting that the engine Juno was fired as planned.
“Everything depends on it” – he stressed the agency quoted the AP chief of a team of researchers from the mission Juno Scott Bolton of Southwest Research Institute in Texas.
While space probes reach the vicinity of Jupiter from the 70s, still a lot of things on this planet do not know how many are on the water, whether it has a dense core, and why shrinking the Great Red stain – distinctive, they became a huge anticyclone, blowing on Jupiter south of the equator at least several hundred years.
during the Juno mission is to spy on the surface of Jupiter by a thick layer of clouds, crossing 5 thousand. kilometers closer to her than any other probe.
The aim of the mission is to determine “how are formed solar systems” – explained Bolton during a meeting with the media.
Because of the large distance from the sun previous flights close to Jupiter was carried out with the use of nuclear power. Juno is the first probe, which was heard as far away thanks to solar power. Juno (having more or less the size SUV) is equipped with three solar panels, like the blades of a windmill. Set so that most of the trip maximize the effect of the sun.
On board the Juno is nine instruments to investigate Jupiter’s gaseous interior and the turbulent atmosphere. There are also three figurines Lego, representing the Roman god Jupiter, the goddess Juno and Galileo Galilei (Galileo).
When Juno fulfill its tasks in 2018. Finally “dives” in Jupiter’s atmosphere and burn. For details on the mission, visit http://tinyurl.com/Jupitermission (PAP)
