Post flight operation of a high peak power neodymium YAG laser aboard the G-449 payload flown on Space Shuttle Columbia mission 61-C

The Nd Yag laser flown on board the G-449 payload completed its postflight testing successfully. There was no indication that the laser had undergone any electronic or optical component failure. A postflight video was taken immediately following the return of the payload to the laboratory. Early anticipation of vibration and temperature changes contributed to the successful operation of the laser. Photographic material resulting from post flight videotape are presented. NASA safety reviews and recommendations supplied the insights which helped contribute to the successful operation of the Nd Yag laser. The safety review data is part of the technical presentation and gives some insight into why the system survived the severe environment of temperature and vibration during the flight of Space Shuttle 61-C.

Systems report for payload G-652: Project origins

Experiments conducted to investigate possible hardware configurations and methodologies for a Get Away Special payload designated G-652 are discussed. Test data collected from the operation of a free electron laser wiggler using simulated ram glow phenomenon are described. Results of an experiment to synthesize organic compounds within a primordial atmosphere using a laser induced plasma are discussed. An experiment is described which utilized neutron bombardment to assess the risk of genetic alterations in embyros in space.

Laser investigations for payload G-652 prior to filing pre-flight accommodation requirements

In anticipation of presenting the preflight accommodations requirements to NASA for approval, the physics, biology, electronic and chemistry aspects of laser experiments which are most advantageous to the flight are investigated. Preliminary laboratory evaluation was targeted with the realization that future flights of the shuttle may begin in 1988. It is the consensus that during the holding time before the resumption of flights, there is an extra margin of perfection which is possible and that the period prior to flight is advantageous technologically. The problems that can be encountered in space flown laser systems are addressed and the analysis of data is offered as a model for preflight accommodation requirement filing.

Results of the joint utilization of laser integrated experiments flown on payload GAS-449 aboard Columbia mission 61-C

The high peak power neodymium YAG laser and the HeNe laser aboard GAS-449 have demonstrated the survivability of the devices in the micro-gravity, cosmic radiation, thermal, and shock environment of space. Some pharmaceuticals and other materials flown in both the active and passive status have demonstrated reduction in volume and unusual spectroscopic changes. X-ray detectors have shown cosmic particle hits with accompanying destruction at their interaction points. Some scattering in the plates is in evidence. Some results of both active and passive experiments on board the GAS-449 payload are evaluated.
