【据美国NASA网站2008年11月4日报道】NASA为美国国家海洋气象局(NOAA)研发的最新极轨运行环境气象卫星NOAA-N Prime已于4日运抵范登堡空军基地,准备于2009年2月4日由联合发射联盟的“德尔它”-2(Delta II)火箭发射发射。

NOAA-N Prime卫星由洛克希德·马丁公司建造,与2005年5月发射的NOAA-N卫星类似。

这颗卫星是洛·马太空系统公司建造的“先进的电视红外观测卫星”-N系列中的最后一颗。这颗卫星将提供一个极轨平台,支持环境监视仪器对地球大气、地表及云层进行成像与测量。

NOAA-N Prime准备发射

Nation's Newest Advanced Polar Operational Environmental Satellite Being Readied for Launch


Wednesday January 21, 2009, 1:00 pm EST

SUNNYVALE, Calif., Jan. 21 /PRNewswire/ -- The NOAA-N Prime spacecraft, a Polar Operational Environmental Satellite (POES), is being prepared for launch from Vandenberg Air Force Base aboard a United Launch Alliance Delta 2 rocket on February 4, 2009. Lockheed Martin (NYSE: LMT - News) built NOAA-N Prime at its Space Systems Company Sunnyvale facility.

NOAA-N Prime is the latest and final spacecraft in the Advanced TIROS-N (ATN) satellite series. All have been designed and built for the National Aeronautics and Space Administration (NASA) and the National Oceanic and Atmospheric Administration (NOAA) by Lockheed Martin since the first Television and Infrared Observational Satellite (TIROS) weather satellite launch in April 1960. Most of the spacecraft in the series have operated far longer than originally expected, earning them a reputation as the workhorse of the civil space Earth-imaging inventory.

"This team has been totally dedicated to providing NASA and NOAA with satellites to extend NOAA's ability to provide environmental data products to users, and reaching this milestone is always very satisfying," says Jeff Vanden Beukel, Lockheed Martin TIROS program director. "Our long-standing partnership with our NASA and NOAA customers is a source of genuine pride for Lockheed Martin."

A constellation consists of two POES satellites circling the planet in nearly north-south orbits. As the Earth rotates, the entire globe, one swath at a time rolls into view of the satellites' instruments. The instruments are continually sensing the entire depth of the atmosphere and report on the following environmental measurements:
    -- Atmosphere Temperatures and Moisture Soundings
    -- Sea-surface Temperatures
    -- Land-surface Temperatures
    -- Cloud Cover and Heights
    -- Precipitable Moisture
    -- Total Ozone
    -- Clear Radiance
    -- Incoming and Radiated Heat

Together these data comprise irreplaceable inputs to the numerical weather forecast model and are vital to weather and climate forecasting. Separately or in combination, the data are utilized to produce sea-surface temperature maps, ice condition charts, snow cover analysis, vegetation maps and other forecasting and management tools.

Additionally, NOAA-N Prime carries an enhanced complement of microwave instruments for the generation of temperature, moisture, surface, and hydrological products in cloudy regions where visible and infrared instruments have diminished capability. NOAA-N Prime also carries search and rescue instruments that are used internationally for locating ships, aircraft, and people in distress. The use of satellites in search and rescue has been instrumental in saving more than 24,500 lives since the inception of the Search and Rescue Satellite-Aided Tracking (SARSAT) system.

The NOAA-N Prime satellite will operate in a circular, near-polar orbit of 464 nautical miles above the Earth with an inclination angle of 98.73 degrees to the equator. Its orbital period, which is the time it takes to complete one orbit of the Earth, will be approximately 102.14 minutes.

The NOAA-N Prime orbit is sun-synchronous, rotating eastward about the Earth's polar axis 0.986 degrees each day, approximately the same rate and direction as the Earth's average daily rotation about the sun. The rotation keeps the satellite in a constant position with reference to the sun for constant scene illumination throughout the year.

NASA's Goddard Space Flight Center, in Greenbelt, Md., is responsible for the procurement, development, launch services, and verification testing of the spacecraft, instruments, and unique ground equipment. Following deployment of the spacecraft from the launch vehicle, Goddard is responsible for the mission operation phase leading to injection of the satellite into orbit and initial in-orbit satellite checkout and evaluation.

Following the launch and a comprehensive on-orbit verification period that lasts 45 days, NASA will turn operational control of the satellites over to NOAA. NOAA will operate the satellites from the Satellite Operations Control Center in Suitland, Md., along with the nation's other environmental satellites that it operates.

NOAA's environmental satellite system is composed of two types of satellites: Geostationary Operational Environmental Satellites (GOES) for national, regional, short-range warning and "now-casting"; and Polar Operational Environmental Satellites (POES) for global, long-term forecasting and environmental monitoring. Both GOES and POES are necessary for providing a complete global weather monitoring system. Both also carry search and rescue instruments to relay signals from people in distress.

Lockheed Martin Space Systems Company, a major operating unit of Lockheed Martin Corporation, designs and develops, tests, manufactures and operates a full spectrum of advanced-technology systems for national security and military, civil government and commercial customers. Chief products include human space flight systems; a full range of remote sensing, navigation, meteorological and communications satellites and instruments; space observatories and interplanetary spacecraft; laser radar; ballistic missiles; and missile defense systems; and nanotechnology research and development. During its five decades of service to the international space community, Space Systems Company has produced some 900 spacecraft, including 380 classified missions and over 150 small satellites.

Headquartered in Bethesda, Md., Lockheed Martin Corporation is a global security company that employs about 140,000 people worldwide and is principally engaged in the research, design, development, manufacture, integration and sustainment of advanced technology systems, products and services. The corporation reported 2007 sales of $41.9 billion.

NOAA-N'上的5台(套)遥感载荷:

* High Resolution Infrared Radiation Sounder (HIRS/4)
The HIRS/4 instrument measures scene radiance in the IR spectrum. The data is also used to determine
ocean surface temperatures, total atmospheric ozone levels, precipitable water, cloud height and
coverage, and surface radiance.
* Advanced Microwave Sounding Unit-A (AMSU-A)
The AMSU-A measures scene radiance in the microwave spectrum. Data from this instrument is used to
calculate global atmospheric temperature and humidity profiles from the Earth’s surface to the upper
stratosphere.
* Microwave Humidity Sounder (MHS)
The MHS is a new instrument for the NOAA series of satellites. It measures profiles of atmospheric
humidity, cloud liquid water content, and provides qualitative estimates of the precipitation rate.
* Solar Backscatter Ultraviolet Radiometer (SBUV/2)
The SBUV/2 measures solar irradiance and Earth radiance (backscattered solar energy) in the near
ultraviolet spectrum (160–400 nm).
* Advanced Very High Resolution Radiometer (AVHRR/3)
The AVHRR/3 detects energy in the visible and IR portions of the electromagnetic spectrum. The instrument
measures reflected solar (visible and near-IR) energy and radiated thermal energy from land, sea,
clouds, and the intervening atmosphere.

高分辨率红外辐射探测仪4型(HIRS/4)
先进微波探测单元-A(AMSU-A)
微波湿度计(MHS)
太阳反向散射紫外辐射计2型(臭氧探测仪)(SBUV/2)
先进甚高分辨率辐射计3型(AVHRR/3)

欢迎了解相关情况的网友提供载荷的详细介绍、参数,有兴趣也可以和风三的载荷比较一下。

好像是地面设施上的氮气供应系统出问题了,故障不排除都不能泄掉已经加注的液氧。(个人理解)
darklighter 发表于 2009-2-4 18:40 | 显示全部楼层
根据NASA任务网站:http://www.nasa.gov/mission_pages/NOAA-N-Prime/main/index.html
发射尝试取消的原因:用来为火箭液氧贮箱和控制系统加压的地面氮气系统出现问题。新的发射时间取决于气象条件以及地面设施的修复情况。

据刚刚进行的气象简报,气象满足发射条件概率:明日20%,周五、周六40%,周日60%。
