THE ENGINEERING DESIGN OF THE ORBITING ASTRONOMICAL OBSERVATORY

The Orbiting Astronomical Observatory (OAO) is designed to provide an accurately stabilized, unmanned platform for astronomical observations from well above the earth's atmosphere. Of primary immediate interest is the observation of stellar radiation in the ultraviolet range, which is severely limited even in balloon experiments because of absorption in the ozone layers. The OAO is a 3600-pound spacecraft that will be placed in orbit by an Atlas Agena D. It can handle optical systems up to 48 inches in diameter, 10 feet in length, weighing 1000 pounds. The key design requirements of the spacecraft are discussed. The reasons behind the configuration are then explained, followed by a discussion of the major subsystems showing how they have been designed to meet the exacting requirements astronomical observation.

The High Energy Astronomical Observatory.

The High Energy Astronomical Observatory (HEAO) is an earth satellite platform designed specifically around the very large and heavy instruments now required to make a significant advance in high-energy astrophysics. This new field of astronomy includes X-ray, gamma-ray, and cosmic-ray studies. The state of knowledge in high-energy astrophysics is discussed, giving attention to X rays, gamma rays, the diffuse component, emission mechanisms, and particle astrophysics. The observational objectives of the HEAO are considered together with the HEAO configuration and the experiments under study for the first HEAO, the HEAO-B, and the HEAO-C. HEAO-A is to be placed in orbit in 1975.-

The Organization and Management of the Virtual Astronomical Observatory

The U.S. Virtual Astronomical Observatory (VAO; http://www.us-vao.org/) has been in operation since May 2010. Its goal is to enable new science through efficient integration of distributed multi-wavelength data. This paper describes the management and organization of the VAO, and emphasizes the techniques used to ensure efficiency in a distributed organization. Management methods include using an annual program plan as the basis for establishing contracts with member organizations, regular communication, and monitoring of processes.

Zelenchukskaya Radio Astronomical Observatory

This report summarizes information about Zelenchukskaya Radio Astronomical Observatory activities in 2012. Last year a number of changes took place in the observatory to improve some technical characteristics and to upgrade some units to the required status. The report provides an overview of current geodetic VLBI activities and gives an outlook for the future.
