This paper reviews recent advances and future challenges in analytical and experimental methods for understanding and verifying the deployment of inflatable structures in space.
A concept has been studied for remote sensing of sea surface salinity form space using a large deployable mesh antenna system.
Experiments have confirmed the feasibility of an innovative, new class of very simple, reliable, low mass, low packaging volume, and low-cost self-deployable structures for space and commercial applications.
Analytical simulation of the inflation process of inflatable structures is key to assessing their robust deployment in space environment.
The Mars Pathfinder mission promises to reap a harvest of geological information about Mars. One of the nearly half dozen instruments making this science data possible is the alpha proton X ray spectrometer (APXS). Using a curium source and backscattering techniques, the APXS will determine the elemental composition of rocks and the soil around the landing site. To ensure information of high fidelity, the APXS sensor face must be aligned to within 20° to the surface of each rock and soil sampling location and be held there for up to 10 hours. This is accomplished through the anthropomorphic deployment mechanism (ADM). The ADM mounts on the back of the Mars rover. Working with the rover, the ADM both actively and passively positions the APXS sensor head against a chosen target. The ADM is an amalgamation of unique solutions to some very challenging design problems. The resulting design is light, flexible, and nearly autonomous. Its straightforward operation rivals that of the human arm in simplicity and elegance.
Overview of ADEPT technology for low ballistic coefficient mechanically deployable entry vehicles.
This is an overview of the National Aeronautics and Space Administration (NASA) Advanced Composite Solar Sail System (ACS3) technology demonstration project mechanisms, their development, the testing they underwent, as well as the lessons learned in those activities. This overview includes an overall description of the primary deployment mechanisms and ground support equipment (GSE) needed for packaging the solar sail system.

Self-deploying space station requirements for inflatable sections
Dispensing system uses a rotating drum, transfer arm, and stationary drum to deploy, reel in, and store an attached hose. This system which eliminates torsion and minimizes strain and wear of flexible hoses, is used for handling flexible cables that have one end permanently attached to an outlet or connector.
