Scientific paper

Lockheed Martin has been using developing deployable shade structures for years. This paper describes one year's development program, which produced three successive versions of Sun Shield models, culminating in a 3.8m×2.8m automatically deploying version. This development effort was in support of future spacecraft (James Webb Space Telescope / JWST, Terrestrial Planet Finder / TPF) that use Sun-isolating shields to deflect the Sun's heat and thus allow the spacecraf to passively cool to the cold-space sink. The configuration chosen was a late-1999 configuration of JWST, of which the largest of the scale models was 1/6 scale. The technologies developed are applicable to a wider range of applications such as light baffles and solar sails.
