On November 14, 2003, the astronomers stained the farthest object of the most known object was made in orbit. They called him Apprehension after the goddess of the ocean inuit. This is a cold, red dwarf planet Billions of billions of miles are creepy in billions of miles before a close approach to our star than our star. The next periodlion occurs in July 2076 and astronomers want to take advantage of this rare earth flying a mission to the mysterious object.
The group of researchers from Italy offers a mission to reach Seedna in seven to 10 years using advanced technology. One paper The archive available in the pre-printed website shows the concepts of two experimental restrictions in a nuclear fusion rocket engine and a new job in Beydan Technology. Propulation technologies can reduce more than 50% of travel time compared to the traditional methods of space travel, collecting clues related to the early formation of the solar system of scientists and explore the theoretical Oort cloud.
When discovered, Sedna was about 8 billion miles (13 billion kilometers) from the Sun. About 8 billion kilometers. (The most famous dwarf planet has a 3.7 billion mile of the sun. At the farthest distance, Seedna is 84 billion miles away from the Sun. The Seedna will be about 7 billion miles away from the Sun. It will be about 7 billion miles away from the Sun, but still far away from the Sun. The ship is close enough to reach the sky object before he returns from a distance from a distance.
The spacecraft has previously went to distances. Voyager started the interdal trip in 1 and 2 in 1977 and has so far over 15 billion miles and 12.7 billion miles. To reach the Neptuna Voyager for 2 to 12 years. According to current technology, scientists estimate During the closest approach, while using Venus, Earth, Jupiter and Neptune, it will last 20-30 years to reach Seedna while using Neptune as weight. This means that the launch window reached Seedna, still means fast approach without open plans in place.
Instead, researchers behind the new study offer us alternative methods to get us faster. The first is currently a direct evolving missile engine (DFD) rocket engine (DFD) developed in the Plasma Physics Laboratory of Princeton. The Fusion-powerful missile engine produces both thrust and electricity from a nuclear fusion reaction that provides more power than chemical missiles.
“DFD,” Researchers wrote on paper, which offers high strikes and sustainable acceleration. “However, they will not be able to support the main engineering and deep space radiation, but it cannot support long-term missions and provide power for tools on the plane. It is still unknown.
Is built on the second concept Available solar sailing technologyStill experimental in his own right. Sun sails are connected to the energy produced by solar photons and light and use the space to advance. Researchers heat sun sails, leave molecules or atoms, and provide acceleration in a process known as a thermal desorption.
The sun sail, which helps the Jupiter’s gravity, can reach Seedna in seven years without the need to carry heavy fuel, according to paper. The idea comes with a set of own difficulties. “When the sun sails are widely studied for deep space applications, the feasibility study for Sedna mission requires an assessment of structural integrity and structural integrity and structural integrity and power existence.”
Despite a little time advantage, the sun sailing mission allowed only to a flyby of Seedna, the DFD engine can enter a spacecraft in the orbit of the dwarf planet for a longer mission. Either the mission will ensure the first direct observation of the unexplored region and help the solar system of scientists to better understand the larger border of the home system.
