NASA will launch a new Jupiter probe

NASA announced on the 24th, will be launched in August 2011 a new Jupiter probe, "Juneau", which took an in-depth exploration of Jupiter.
U.S. space agency said, "Juno" by the U.S. Lockheed - Martin Corporation to build, under the NASA Jet Propulsion Laboratory in charge of running the entire mission. It is estimated that in 2016, "Juno" are expected to arrive around Jupiter running on the track. It can be about a year running 32 laps around Jupiter, through its exploration, scientists hope to understand this giant planet Jupiter's formation, evolution and structure.
"Juno" project chief scientist Scott Bolton 24 in a press release said that Jupiter formed very early, catch the sun and leave behind the formation of interstellar material left behind by many, the giant planets of the solar system called the "original model . " He said: "Earth, Jupiter's large mass makes it able to retain the original composition, which provides us with a history of the solar system the way back."
Jupiter from the sun more than 640,000,000 km, the distance between the sun and the earth is 5 times. Despite so far away from the sun, "Juno" power supply system is still designed in the form of solar panel power supply, so it's very high energy efficiency design requirements.
"Juno" before, the United States in 1989 specifically to detect the launch of Jupiter's "Galileo" probe, was a great deal of data about Jupiter's survey. "Galileo" was in September 2003 in accordance with the procedure in the crash of Jupiter.
"Juno" NASA is "Frontiers" plan to implement the second exploration projects. The first is the January 2006 launch of the "New Vision" probe, which now also fly to Pluto on the way.
美国宇航局24日宣布，将于2011年8月发射一个新的木星探测器“朱诺”，展开对木星的深入探测。
　　美宇航局介绍说，“朱诺”由美国洛克希德-马丁公司建造，宇航局下属喷气推进实验室负责整个探测任务的运行。预计到2016年，“朱诺”将飞抵绕木星运行的轨道上。它每年大约可绕木星运转32圈，通过它的探测，科学家希望了解木星这颗巨行星的形成、进化和结构等。
　　“朱诺”项目首席科学家斯科特·博尔顿在24日的一份新闻公报中说，木星形成得非常早，捕获了太阳形成后遗留下的许多星际物质，堪称太阳系巨行星的“原始模型”。他说：“与地球不同，木星的超大质量使得它的原始成分得以保留下来，这为我们提供了一条回溯太阳系历史的途径。”
　　木星距离太阳超过6.4亿公里，是地球与太阳距离的5倍。尽管距太阳如此遥远，“朱诺”供电系统仍设计成太阳能电池板供电形式，因此它的能效设计要求极高。
　　在“朱诺”之前，美国曾于1989年发射过专门探测木星的“伽利略”探测器，获得了大量有关木星的探测数据。“伽利略”已于2003年9月按程序坠毁在木星。
　　“朱诺”是美国宇航局“新疆界”计划实施的第二个探测项目。第一个是2006年1月发射的“新视野”号探测器，它如今还在飞往冥王星的途中。
