SPACE DEBRIS RESEARCH IN CHINA(2000-2002)

Space debris is is referred to as the human made pollution in the space environment.Ever since the first launch of man made satellite in 1957, millions of kilograms of objects have been sent into the space. Large space objects that are traceable and cataloged by ground base telescope and radar reach around 9 000, becoming grave threat to the social development of human beings as well as astronautics.

斯蒂芬·戈罗夫教授编《美国空间法:本国和国际规章》(1985年英文版)

<正> 近三十年来,空间科技的迅速发展,使人类活动越过空气空间进入外层空间。为了解决各国在探索、利用和开发外层空间一系列问题,形成了国际法的一个新分支外层空间法。外空法的特点是:历史短,发展快,虽然在长期、广泛的实践和惯例方面,同国际法的其他部门相比,显得单薄一些,但却拥有内容丰富的国际条约、公约、协定和各国的有关法律、规章、条例及一些案例等等。作为空间大国之一的美国在处理空间事业大发展中出现的各种法律问题日益增多。美国戈罗夫教授编辑的《美国空间法:本国和国际规章》正是为了适应这方面的需要而出版的。     

中国1987—1990年科学实验卫星中空间辐射剂量信息的热释光分析方法

本文介绍了实验卫星中空间辐射剂量信息的热释光分析方法。应用LiF(Mg,Cu,P)探测器及程序加热方法,分析测定了几次实验卫星中空间辐射日平均剂量,均在20mrad/d以下。应用LiF(Mg,Ti)和Caso_4(Tm)探测器及发光曲线反卷积分析方法,研究了探测器本底荧光与低温峰影响的减除技术和高LET粒子造成的微观剂量分布不均匀情况。     

非线性微分方程y′=sum from i=0 to n (a_i(x)y~i)解空间的显易结构

文章给出了非线性微分方程,具有“第一显易结构”的充分必要条件。     

The radiation controlled balloon (RACOON)

The RACOON concept permits the flight of large, low-cost polyethylene balloons for several weeks at stratospheric altitudes without ballast. The theory of operations is described. The RACOON balloon ascends each morning and descends at night. This movement of 15 to 20 km in altitude provides an ideal platform for vertical soundings and sampling measurements in the stratosphere. Results of a number of globe-circling flights are presented.     

The James Webb Space Telescope (JWST)

The James Webb Space Telescope is a 6.5 m, infrared space telescope designed to be launched in 2013 aboard an Ariane 5. The JWST program is a cooperative program with the Goddard Space Flight Center (GSFC) managing the project for NASA. The prime contractor for JWST is Northrop Grumman Space Technology (NGST). JWST’s international partners are the European Space Agency (ESA) and the Canadian Space Agency (CSA). JWST will address four major science themes: end of the dark ages: first light and reionization; the assembly of galaxies, the birth of stars and protoplanetary systems; and the formation of planetary systems and the origins of life. We discuss the design of the observatory and review recent progress on the JWST program.     

The performance of the GMS (HIMAWARI)

The pserformance of the GMS (HIMAWARI) during the three years since it was launched in the middle of 1977 has been described with emphasis in the measurements of meteorological parameters such as sea surface temperature, cloud vectors and center position of typhoons alluding to their accuracy.     

The Scanning Sky Monitor (SSM) on ASTROSAT

The Scanning Sky Monitor is one of the experiments onboard the ASTROSAT, an Indian multiwavelength astronomy satellite mission. This experiment will detect and monitor X-ray transients in the energy band 2–10 keV. It is similar in design to the ASM on RXTE. It consists of position-sensitive proportional counters with one-dimensional mask. We describe the configuration of the experiment. We also discuss some of the results obtained using a detector which has already been fabricated and tested in our laboratory.     

The Living With a Star (LWS) Sentinels

This paper gives a short account of the development of the living with a star Sentinels element. The Sentinels element is the heliospheric portion of the NASA program focused on improving our understanding of geo-effective events in the Sun–Earth connected system. The primary objectives of Sentinels are the investigation of the initiation and evolution of solar transients in the inner heliosphere, the acceleration and propagation of solar energetic particles, and the long term climatic change and structure of the inner heliosphere into which all of these geo-effective structures erupt. Due to the large volume of space to be covered, Sentinels will have to rely on, besides a dedicated mission, the observations of spacecraft from other programs of NASA and international partners along with a robust theoretical and modeling effort. The upcoming Sentinels Science and Technology Definition Team will develop specific details of this element.     

The Planetary Laboratory for Image Analysis (PLIA)

The observation, characterization, and understanding of planetary atmospheres are key components of Solar System exploration. Their study requires, among other observations, the use of image data acquired from spacecrafts. The basic tasks that are generally used to work with planetary image data are: image navigation, projection, image processing, limb-darkening correction, composition of multiwavelength images and mosaicing. We illustrate the mathematical techniques required for the study of planetary images obtained from spacecrafts using as an example our own software package (PLIA). We present examples of analysis of Galileo SSI, Cassini ISS and Venus Express VIRTIS observations covering a large range of image peculiarities. The paper is organized as a guide for anyone willing to replicate one or several of the capabilities incorporated in the PLIA software. An open source version of PLIA for astronomical image processing is available.     

The accuracy of ionogram-derived N(h) profiles

At the Millstone Hill station the Incoherent Scatter Radar (ISR) and a Digisonde 256 are simultaneously operating. Some characteristic true heights determined by both instruments are compared with each other, possible reasons for observed difference are indicated.     

The United Nations Basic Space Science Initiative (UNBSSI)

Since 1991 the United Nations Office for Outer Space Affairs has been conducting a series of workshops on basic space science under its United Nations Programme on Space Applications. Up to 2004 the workshops focussed on capacity building efforts in basic space science, in particular for the benefit of developing countries. From 2005 onwards the workshops and their related activities contributed to the celebration of the International Heliophysical Year 2007. Together these activities and workshops constitute the United Nations Basic Space Science Initiative of the United Nations Office for Outer Space Affairs. This paper reflects on the achievements and outcomes of the Initiative and informs about considerations for its future evolution.     

The International DORIS Service (IDS): Toward maturity

DORIS is one of the four space-geodetic techniques participating in the Global Geodetic Observing System (GGOS), particularly to maintain and disseminate the Terrestrial Reference Frame as determined by International Earth rotation and Reference frame Service (IERS). A few years ago, under the umbrella of the International Association of Geodesy, a DORIS International Service (IDS) was created in order to foster international cooperation and to provide new scientific products. This paper addresses the organizational aspects of the IDS and presents some recent DORIS scientific results. It is for the first time that, in preparation of the ITRF2008, seven Analysis Centers (AC’s) contributed to derive long-term time series of DORIS stations positions. These solutions were then combined into a homogeneous time series IDS-2 for which a precision of less than 10 mm was obtained. Orbit comparisons between the various AC’s showed an excellent agreement in the radial component, both for the SPOT satellites (e.g. 0.5–2.1 cm RMS for SPOT-2) and Envisat (0.9–2.1 cm RMS), using different software packages, models, corrections and analysis strategies. There is now a wide international participation within IDS that should lead to future improvements in DORIS analysis strategies and DORIS-derived geodetic products.
