This paper gives a brief description of the space policy and activities of the Federal Republic of Nigeria implemented through National space Research and development Agency, (NASRDA) Abuja, Nigeria. NASRDA is one of the research institutions under the aegis of the Nigeria Federal Ministry of Science and Technology with a mission to pursue the research and development of space science and technology.The NASRDA policy aims at ensuring that Nigeria vigorously pursues the attainment of Space Capabilities as an essential tool for its socio-economic development and the enhancement of the quality of life of its people.

1. Introduction

1.1. National space policy and visions

Since the Russians launched SPUTNIK into the orbit in 1957, space exploration and the exploitation of space resources have become dominant factors in communication, national security, natural resources management, prediction, navigation and management of natural disasters. The spin-offs of space exploration are generating new products, new ideas and solutions in medicine, manufacturing industry, agriculture, microwave engineering, food technology and material science. Thus space technology can impact on the socio-economic development of any Nation when integrated into the development strategy. In view of the above, Nigerian government decided to evolve a space policy to address the space needs of the nation. Following the Nigeria space policy, National Space Research and Development Agency (NASRDA) was established to administer the space programme in Nigeria.
