In February, NASA and the European Space Agency will meet in Washington, DC, to select one of the two missions designed to study the outer Solar System.
What do they choose: to go to Saturn’s moon Titan, or to send a pair of orbiters to explore Jupiter and some of its moons?
Jupiter’s icy moon Europa (left) and Misty Saturn’s moon Titan (right) are the two main objectives of the proposed space poletov.Na two moons, by the scientists could support life. Perhaps some form of life is there now? Each of the flights would cost nearly $ 4 billion. (Image: NASA / JPL)
Titan may be the only place in the solar system besides Earth where present on the surface zhidkosti.Orbitalny apparatus Cassini and its probe Huygens, which landed on the moon in 2005, found many interesting features, including river systems, dunes and lakes of liquid ethane and methane. This organic soup potentially could give rise to the development of life forms. (Image: ESA / NASA / USGS)
To study Titan orbiter NASA will develop, and a balloon and a lander designed to descend to the surface of the lake of methane will provide the European Space Agency (ESA). Air inside the balloon, the heated atmosphere of Titan, would allow the ball to drift at an altitude of about 10 kilometers from the surface for six months or more. (Image: ESA / NASA)
In addition, the flight to Titan will provide researchers the opportunity to better understand the icy moon of Saturn’s moon Enceladus (Enceladus), at the south pole is seen enormous emissions of water vapor and ice. The energy source of these eruptions is unclear. According to experts, before going into orbit around Titan, the main probe will be able to complete at least seven flybys of the moon during a two-year tour of the Saturn system. (Image: ESA / NASA)
The second proposed mission involves sending two orbiters to study Jupiter and several of its sputnikov.Vklad NASA - the orbiter to study in Europe, which is believed to have a liquid water ocean beneath the icy poverhnostyu.ESA in turn would direct its orbiter on study of Ganymede, which is the largest satellite in the solar system and the only satellite has its own magnetic field.

The spacecraft Galileo photographed close-up face of Europe in 1996, revealing interesting details, reminiscent of floating ice on Zemle.Orbitalny NASA’s able to take pictures with a resolution of up to six times sharper than the sharpest images existing in Europe. In addition, it will be possible to obtain for analysis 3000 times dannyh.Kartografiya surface could help to choose the best place in the future landing sites for future missions. The bottom of the inner ocean of Europe, as scientists assume, is a rock that would ensure the availability of nutrients, and this in turn increases the chances of success when looking for signs of life.

Working in tandem in the orbit of Jupiter, the two orbiters could spend the simultaneous measurement of its magnitosfery.Eto intense magnetic field surrounds the planet, accelerating charged particles and producing intense radiation fluxes and the aurora, including the picture in the photo shine at the North Pole of the planet.
