Governmental agencies charged with protecting the health of the population and agriculture have several main strategic
objectives including the detection of harmful agents, the identification of vulnerable biological targets, the prediction of
health outcomes and the development of countermeasures. New technologies are urgently needed in several critical
areas of bio-chemical defense: economical and minimally invasive biosensors for field use in humans and other species
important for agriculture and infrastructure, universal analytical platforms for broad-based, early warnings of threats
and technologies guiding the development of countermeasures. A new technology called Stress Response Profiling
(SRP) was recently developed by the Gaia Medical Institute. SRP provides a universal analytical platform for
monitoring health status based on measurements of physiological stress. The platform is implemented through handheld
devices that can be used for noninvasive detection of early-stage health problems. This paper summarizes SRP
features, advantages and potential benefits for critical areas of homeland defense.
A concept study was performed in 1994 to develop a mission design for a telescope to achieve the highest possible spatial resolution in the 10 - 30 micron range within a $DOL200 million mission cost cap. The selected approach for the resulting Mid-InfraRed Optimized Resolution Spacecraft (MIRORS) concept design utilizes a partially filled five meter aperture. A simple deployment scheme permits this spacecraft to be fit within the volume envelope and mass capabilities of a Med-Lite launch vehicle. Low bandwidth cryogenic actuators, which dissipate no heat once set, will align the optics after on-orbit thermal stability is achieved. Image stabilization, fine point and stray-light control are achieved through use of a novel actuated Offner relay. Image reconstruction techniques developed for IRAS will be used to deconvolve nearly diffraction-limited images at 10 microns (FWHM approximately 0.5 arcsec). A Lissajous orbit about the L2 sun-earth libration point (sun-earth- L2 on a straight line) is adopted because its extremely stable thermal environment results in correspondingly high telescope mechanical stability and optical performance. This orbit, combined with a spacecraft configuration which incorporates an inflatable sunshield and a deployable four- stage v-groove thermal shield, enables the optics to radiatively cool <25 K. The large format focal plane will be actively cooled to <8 K by a vibration-free, long-life sorption refrigerator.
