Soviet Steps Toward Permanent Human Presence in Space
SALYUT: Soviet Steps Toward Permanent Human Presence in Space December 1983 NTIS order #PB84-181437 Recommended Citation: SALYUT: Soviet Steps Toward Permanent Human Presence in Space–A Technical Mere- orandum (Washington, D. C.: U.S. Congress, Office of Technology Assessment, OTA- TM-STI-14, December 1983). Library of Congress Catalog Card Number 83-600624 For sale by the Superintendent of Documents, U.S. Government Printing Office, Washington, D.C. 20402 Foreword As the other major spacefaring nation, the Soviet Union is a subject of interest to the American people and Congress in their deliberations concerning the future of U.S. space activities. In the course of an assessment of Civilian Space Stations, the Office of Technology Assessment (OTA) has undertaken a study of the presence of Soviets in space and their Salyut space stations, in order to provide Congress with an informed view of Soviet capabilities and intentions. The major element in this technical memorandum was a workshop held at OTA in December 1982: it was the first occasion when a significant number of experts in this area of Soviet space activities had met for extended unclassified discussion. As a result of the workshop, OTA prepared this technical memorandum, “Salyut: Soviet Steps Toward Permanent Human Presence in Space. ” It has been reviewed extensively by workshop participants and others familiar with Soviet space activities. Also in December 1982, OTA wrote to the U. S. S. R.’s Ambassador to the United States Anatoliy Dobrynin, requesting any information concerning present and future Soviet space activities that the Soviet Union judged could be of value to the OTA assess- ment of civilian space stations. -

Extension of Upper Limit Servers and Spectral Analysis of the X-Ray Binary GRO J1744−28
Extension of Upper Limit Servers and spectral analysis of the X-ray binary GRO J1744−28 Master's Thesis in Physics Presented by Ole K¨onig Wednesday 31st July, 2019 Dr. Karl Remeis-Sternwarte & ECAP Friedrich-Alexander-Universit¨atErlangen-N¨urnberg Supervisor: Prof. Dr. J¨ornWilms Abstract This thesis is about applications in the field of X-ray astronomy. It is divided into a software development and data analysis part. The Upper Limit Servers allow the user to generate long-term lightcurves of X-ray sources. They combine historical data and calculate upper limits in real-time. A web-based front- end provides facile querying, plotting and downloading of the data. They utilize data from 12 satellites including current observatories such as XMM-Newton, back to ROSAT, Einstein, Ariel V and Uhuru. This enables the user to query 50 years of X-ray data and, for instance, study outburst behavior of transient sources. Part I of this thesis describes the software layout, database format, as well as nine X-ray missions, which I implemented. In particular, the implementation of catalog calls, image footprints, point spread functions, and vignetting is described. The count rate is converted to a flux by approximating the spectral shape with an absorbed power-law or black body. In order to outline possible applications of this software, I interpret four lightcurves. In the second part, the spectral analysis of the low-mass X-ray binary GRO J1744−28 is presented. The ∼29 ks data was taken with the Nuclear Spectroscopic Telescope Array (NuSTAR) in 2017 February, during the source's fourth reactivation phase after three years of quiescence. -
