Observation of Light Curves of Space Objects Hirohisa Kurosaki Japan
Observation of Light Curves of Space Objects Hirohisa Kurosaki Japan Aerospace Exploration Agency Toshifumi Yanagisawa Japan Aerospace Exploration Agency Atsushi Nakajima Japan Aerospace Exploration Agency Abstract Geostationary orbit and low earth orbit have many artificial satellites, and the accidents of these satellites affect every area such as weather forecasts and communications. In the optical observation, the periodical change of the brightness which is caused by the type and the shape of the satellite is seen. In the case of LEO debris, since the movement is fast, it crosses the field of view in several seconds. We used an observation method to get the data of LEO debris. In case of the GEO debris, the rate of motion is slow in comparison with LEO debris. Fixed stars are observed by the same position on the image when the telescope is operated in sidereal tracking mode. Then, space objects are recorded on the image with streaks of light. In this paper, the observation and the detection method of light curve of geostationary orbit debris are discussed. Observing the changes of the operative satellites with some time intervals may help to detect the abnormalities and accidents of them. 1. INTRODUCTION Artificial satellites that have finished their missions and used rockets are called space debris. Most of them are not under any control. The space debris problem must be solved to perform future space development and maintain safety. Many artificial satellites indispensable for human activities circle the earth. If one of these satellites malfunctions, many human activities are impacted. An artificial satellite is monitored to control its trajectory while it is in operation. -

These approaches are 23 complicated since the ABI does not have a “green” (0.55 µm) spectral band. Despite this 24 limitation, representative true color images can be built. -

During the decade from 1989–1998, NASA used two types of launch systems, one consisting of several families of expendable launch vehicles (ELV) and the second consisting of the world’s only partially reusable launch system—the Space Shuttle. A significant challenge NASA faced during the decade was the development of technologies needed to design and implement a new reusable launch system that would prove less expensive than the Shuttle. Although some attempts seemed promising, none succeeded. This chapter addresses most subjects relating to access to space and space transportation. It discusses and describes ELVs, the Space Shuttle in its launch vehicle function, and NASA’s attempts to develop new launch systems. Tables relating to each launch vehicle’s characteristics are included. The other functions of the Space Shuttle—as a scientific laboratory, staging area for repair missions, and a prime element of the Space Station program—are discussed in the next chapter, Human Spaceflight. This chapter also provides a brief review of launch systems in the past decade, an overview of policy relating to launch systems, a summary of the management of NASA’s launch systems programs, and tables of funding data. The Last Decade Reviewed (1979–1988) From 1979 through 1988, NASA used families of ELVs that had seen service during the previous decade. -

That has now changed due to a number of factors, among the more dominant being economics, advanced and improved technologies and national imperatives.
