The presentations were scheduled during a meeting of the Society for Photo-optical Instrumentation Engineers, or SPIE, Sunday through Thursday.
The National Aeronautics and Space Administration said many of its presentations will involve the JWST -- a 21st-century space observatory that will peer back more than 13 billion years in time to understand the formation of galaxies, stars and planets and the evolution of our own solar system.
The JWST -- a joint project of NASA, the European Space Agency and the Canadian Space Agency -- is expected to be launched into space in 2013.
During the SPIE meeting, NASA scientists were to present, among other things, the JWST's cryogenic composite structure and the instrument's wavefront sensing and control subsystem that keeps all 18 individual mirror segments perfectly configured to act as one large mirror.
SPIE is an international society advancing an interdisciplinary approach to the science and application of emerging technologies of nanotechnology, photonic devices and solar energy.
