This technology enables the NIRSpec instrument of JWST to perform spectroscopy on up to 100 objects at a time. Microshutters provides giant step beyond fixed slit spectroscopy in that this technology will permit faster mapping and cataloging of faint infrared objects due to the number of objects that can be imaged at one time.

        The success criteria were met for all three units (life, radiation, and environmental) that were tested. The TRL6 Test Plan demonstrated:

The robustness of the microshutter arrays.

The performance testing shows the arrays will survive launch environments and once on station will operate for many years in the harsh radiation environment of space.

The production team thoroughly understands the manufacturing processes and techniques in order to repeatedly produce high quality arrays suitable for space flight use.
