MSFC Skylab electrical power systems mission evaluation

The design, development, and operation of the Skylab electrical power system are discussed. The electrical systems for the airlock module of the orbital workshop and the Apollo telescope mount are described. Skylab is considered an integral laboratory, however, both cluster and module hardware distinct sections are included. Significant concept and requirement evolution, testing, and modifications resulting from tests are briefly summarized to aid in understanding the launch configuration description and the procedures and performance discussed for in-orbit operation. Specific problems encountered during Skylab orbital missions are analyzed.

MSFC Skylab Apollo Telescope Mount thermal control system mission evaluation

The Skylab Saturn Workshop Assembly was designed to expand the knowledge of manned earth orbital operations and accomplish a multitude of scientific experiments. The Apollo Telescope Mount (ATM), a module of the Skylab Saturn Workshop Assembly, was the first manned solar observatory to successfully observe, monitor, and record the structure and behavior of the sun outside the earth's atmosphere. The ATM contained eight solar telescopes that recorded solar phenomena in X-ray, ultraviolet, white light, and hydrogen alpha regions of the electromagnetic spectrum. In addition, the ATM contained the Saturn Workshop Assembly's pointing and attitude control system, a data and communication system, and a solar array/rechargeable battery power system. This document presents the overall ATM thermal design philosophy, premission and mission support activity, and the mission thermal evaluation. Emphasis is placed on premission planning and orbital performance with particular attention on problems encountered during the mission. ATM thermal performance was satisfactory throughout the mission. Although several anomalies occurred, no failure was directly attributable to a deficiency in the thermal design.

MSFC Skylab student project report

The Skylab Student Project some 4000 students submitted experiments from which twenty-five national winners were selected. Of these, eleven required special flight hardware, eight were allowed to obtain data using hardware available for professional investigations, and the remaining six were affiliated with researchers in alternate fields, since their proposals could not be accommodated due to complexity or similar incompatibility. The background of the project is elaborated and experiment performance results and evaluations are touched upon.

MSFC's utilization of existing design technology in the Skylab program

In the design of Skylab use was made in a number of cases of technological experience obtained in connection with earlier phases of the space program. In the development of the payload shroud use was made of Saturn V flight data. The shroud thrusting joint system was an adaptation of a system flown on the Titan IIIC. Scientific airlock hardware for Skylab was available from the Apollo Program. The design of the Orbital Workshop was based on the technology base provided by Saturn programs. Details regarding the repair tools used for correcting orbital workshop meteoroid shield/solar array anomalies which occurred during the ascent are discussed along with a commercial concept for coolant resupply, giving attention to aid provided by already existing technological developments.

MSFC engineering support to Skylab operations

Major engineering support provided during the Skylab mission from the Marshall Space Flight Center and its contractors to the Mission Control Center at Houston was essential to Skylab success. The need for this type of support was anticipated during premission preparations due to the complexity and first-flight nature of the Skylab, but the requirements were greatly magnified by the problems encountered early in the mission. The MFSC engineering support organization and its interface to the Mission Control Center is described. The importance of close cooperation between the operating and engineering organizations in this type of mission is discussed. Illustrations are given from more than 1800 systems analysis actions worked out during the nine-month Skylab mission by more than 600 support engineers.
