2006年1月19日,新的地平线宇宙飞船从阿纳斯五号火箭上的卡纳维拉尔角发射升空。
这次任务的目标是探索冥王星和神秘的柯伊伯带。
如果成功,美国将是第一个完成太阳系初步侦察的国家。
但这不是一般的旅程。
冥王星于1930年由Clyde W. Tombaugh发现,离地球超过29亿英里,有一个椭圆轨道,需要248年才能绕太阳转。
自发现以来,冥王星仅完成了其完整轨道的百分之三十五。
因此,当New Horizons到达目的地时,科学家们没有完整的测量结果来确认其确切的位置。
根据他们对这些有限数据的计算,他们预测在2015年夏天,即推出后九年半的飞行时间。

关键任务集成电路
AMI Semiconductor(安森美半导体于2008年收购)在New Horizons太空船的发展中发挥了至关重要的作用。
AMIS产生了Rad Harddened by Design(RHBD)错误检测&
用于ICs LLC的校正(EDAC)编码器/解码器(编解码器),这是一家领先的抗辐射设计解决方案公司。
EDAC集成电路(IC)为航天器的固态存储器记录设备提供数据故障保护,以防止辐射效应和其他环境噪声。
如果没有这个关键组件,检索到的数据可能会损坏或丢失,从而导致项目失败。
IC设计始于1995年,采用AMIS 1微米CMOS工艺。
为了实现深空探测所需的辐射抗扰性,IC在设计阶段应用了RHBD技术。
该IC于1997年制造,于1998年初通过了空间资格测试,并运往NASA工程师。
芯片被整合到太空飞行器中,并在2006年发射之前进行了大量测试。
这些测试对于确保New Horizons能够在近十年的长途旅行中幸存下来至关重要。

今天,安森美半导体和集成电路有限责任公司继续设计和制造空间,航空和高可靠性专用集成电路(ASIC),以满足各种应用的恶劣辐射环境。
通过使用安森美半导体商用110 nm数字ASIC流程的先进设计和工艺技术,客户可以从缩短的设计和制造周期时间以及优越的价格中受益。
成功!
新视野到达冥王星
2015年7月14日,太空探测器在冥王星7,800英里范围内通过,成为第一个探测矮人植物的太空船。
不到二十四小时后,NASA收到数据和图像以确认其成功。
第一张令人惊叹的照片展现了高达11,000英尺的冰山,与落基山脉的高度相当。
在接下来的几个月里,科学家们将处理和分析在这一历史事件中捕获的数据。
根据第一印象,这肯定是一个惊人的启示。

关于新视野
约翰斯·霍普金斯大学应用物理实验室(APL)位于马里兰州劳雷尔,负责设计,建造和运营新视野号航天器并管理美国宇航局科学任务理事会的任务。在为期九年半的飞行中,它飞行了超过30亿英里
其中包括2007年与木星的近距离接触。新地平线处于良好状态,新地平线的首席研究员艾伦·斯特恩表示,该太空船有足够的力量可以持续到2030年代中期。
到那时,距离太阳将近93亿英里。
美国宇航局尚未决定他们是否会在2015年之后为新地平线提供资金。
更新:
截至2016年10月25日,一年多以后,New Horizons已经将所有信息传回地球,这是自2015年7月飞行以来的15个月过程。阅读更多信息:http://bit.ly/

On January 19, 2006, the New Horizons spacecraft was launched from Cape Canaveral aboard an Atlas V rocket. The goal of this mission was to explore Pluto and the mysterious Kuiper Belt. If successful, the United States would be the first nation to complete the initial reconnaissance of the solar system. But this was no ordinary journey. Discovered in 1930 by Clyde W. Tombaugh, Pluto is more than 2.9 billion miles from earth, has an elliptical orbit and takes 248 years to circle the sun. Since its discovery, Pluto has only traversed thirty five percent of its full orbit. As a result, scientists did not have a complete set of measurements to confirm its exact position when New Horizons reached its destination. Based on their calculations with this limited data, they predicted a fly-by in summer, 2015, nine and a half years after launch.
NASA's New Horizons Spacecraft
Mission Critical Integrated Circuit
AMI Semiconductor (acquired by ON Semiconductor in 2008) played a vital role in the development of the New Horizons spacecraft. AMIS produced a Rad Hardened by Design (RHBD) Error Detection & Correction (EDAC) Coder/Decoder (Codec) for ICs LLC, a leading rad hard design solutions company. The EDAC integrated circuit (IC) provides data fault protection against radiation effects and other environmental noise for the spacecraft’s solid state memory recording device. Without this critical component, data retrieved could be corrupt or lost, rendering the project a failure. The IC design began in 1995 and used the AMIS 1-micron CMOS process. In order to achieve the radiation immunity required for deep space exploration, ICs applied RHBD techniques during the design phase. Manufactured in 1997, the IC passed space qualification testing in early 1998 and shipped to NASA engineers. There the chip was integrated into the space vehicle and underwent extensive testing prior to the 2006 launch. These tests were essential to ensure that New Horizons could survive it’s nearly decade long excursion.
ON Semiconductor & ICs, LLC Rad Hard Solutions
Today ON Semiconductor and ICs, LLC continue to design and manufacture Space, Aerospace and Hi-Reliability Application Specific Integrated Circuits (ASICs) that meet the harsh radiation environments for a variety of applications. By combining advanced design and process techniques using the ON Semiconductor commercial 110 nm digital ASIC flow, customers benefit from reduced design and manufacturing cycle times and superior pricing.
Success! New Horizons Reaches Pluto
On July 14, 2015, the space probe passed within 7,800 miles of Pluto, making it the first spacecraft to explore the dwarf plant. Less than twenty-four hours later, NASA received data and images to confirm its success. The first stunning photos reveled ice mountains as high as 11,000 feet, comparable to the height of the Rockies. Over the next several months, scientists will process and analyze data captured during this historic event. Based on first impressions, this is sure to be a spectacular revelation.
First detailed images shows ice mountains the size of the Rockies
About New Horizons
The Johns Hopkins University Applied Physics Laboratory (APL) in Laurel, Maryland, designed, built, and operates the New Horizons spacecraft and manages the mission for NASA’s Science Mission Directorate. During the nine and a half year flight, it traveled over three billion miles that included a close encounter with Jupiter in 2007. New Horizons is in excellent condition, and Alan Stern, the principal investigator of New Horizons, says the spacecraft has enough power to continue into the mid 2030s. By that time, it will be nearly 9.3 billion miles from the sun. NASA has yet to decide if they will fund New Horizons beyond 2015.
Update:
As of October 25th of 2016, more than a year later, New Horizons has transmitted back all information to Earth in what has been a 15 month process since the fly by in July 2015. Read more here: http://bit.ly/2ePZ1ln
