Astronomy Science ~ Planet Mars adventure save the dream that has yet to materialize. The red planet is the goal of the next man, since astronaut Eugene Cernan became the last man stand on the Moon 42 years ago. The US space agency, NASA, did not want to be careless. The fastest trip to Mars takes six months

Now two scientists, Francesco Topputo und Edward Belbruno, proposes new paths that not only remove the dependency of the constellation of the planets, but it also requires less fuel than the concepts of NASA. During each trip to Mars using a route called Hohmann transfer orbit. The service gives the window a short time because it depends on a constellation of Earth and Mars, so that the travel time ranges from a maximum of six months.

Unfortunately the exact constellation occurs only once every two years. Beyond that, the spacecraft not only have to fly longer, but also faced with greater risk. Hohmann transfer orbit also requires every maneuver spacecraft went into orbit before the braking, because the plane go faster than Mars itself.

Instead the proposed route does not require Tapputo Belbruno and braking maneuvers. In the concept of the so-called low-energy transfer, the aircraft does not fly directly to Mars, but bounced at low speed.

Mars moves faster in its orbit track will appear on the back and hugged the plane in the gravitational force. This phenomenon is known as the Ballistic Capture. "Therein lies the magic. Like a fly in formation," said Belbrunno the scientific journal "Scientific American."

So aircraft no longer require a braking maneuver, which saves fuel by 25 percent-This method is not new. Belbruno been projected flight path unmanned spacecraft belonging to Japan, Hiten to the Moon in 1991. At that time he was using the same technique.

Belbruno proposals received by NASA. "This opens up a new perspective for us," said James Green NASA's planetary science division director of the scientific journal "Scientific American." With that method, NASA, can save resources and money.
