Debris/Ice/TPS Assessment and Integrated Photographic Analysis of Shuttle Mission STS-80

A debris/ice/thermal protection system (TPS) assessment and integrated photographic analysis was conducted for Shuttle mission STS-80. Debris inspections of the flight elements and launch pad were performed before and after launch. Icing conditions on the External Tank were assessed by the use of computer programs and infrared scanned data during cryogenic loading of the vehicle, followed by on-pad visual inspection. High speed photography of the launch was analyzed to identify ice/debris sources and evaluate potential vehicle damage and/or in-flight anomalies. This report documents the ice/debris/thermal protection system conditions and integrated photographic analysis of Shuttle mission Space Transportation System (STS-80) and the resulting effect on the Space Shuttle Program.

Locating and Determining the Nature of a Persistent Hard X-Ray Source GROJ1814-12

The nature of the persistent hard X-ray source GROJ1814-12 discovered by BATSE a year ago is puzzling. Several potential X-ray sources are in the approximately 25 ft radius error box. Our XTE scanning observation attempted to determine the exact position of the hard X-ray source with respect with other sources. No obvious candidate is emerging from the analysis. A report is being prepared by the observing group. The persistent hard X-ray source GROJ1814-12 might be an example of a low-mass X-ray binary producing a strong flux of hard X-rays, and therefore be of the greatest importance for the theory of neutron star emission.

Investigation Into The Effects of Microsecond Power Line Transients On Line-Connected Capacitors

An investigation was conducted into the effect of power-line transients on capacitors used by NASA and installed on platform primary power inputs to avionics. The purpose was to investigate whether capacitor voltage rating needs to be derated for expected spike potentials. Concerns had been voiced in the past by NASA suppliers that MIL-STD-461 CS06-like requirements were overly harsh and led to physically large capacitors. The author had previously predicted that electrical-switching spike requirements representative of actual power-line transient potentials, durations and source impedance would require no derating. This investigation bore out that prediction. It was further determined that traditional low source impedance CS06-like transients also will not damage a capacitor, although the spikes themselves are not nearly as well filtered. This report should be used to allay fears that CS06-like requirements drive capacitor voltage derating. Only that derating required by the relatively long duration transients in power quality specification need concern the equipment designer.
