The Stellar Imager (SI) Vision Mission is an ultraviolet/optical,
deep-space telescope designed to image stars similar to our sun with 0.1
milliarcsecond resolution. In addition to providing previously unattainable
views of the surfaces and, via spatially-resolved asteroseismoloy, interiors
of solar and other type stars, SI will reveal the inner regions and winds
of active galactic nucleii (AGN) and the dynamics of many systems and
processes throughout the universe.
The Principal Investigator of the Stellar Imager concept development is
Dr. Kenneth Carpenter of the ExoPlanets and Stellar Astrophysics Laboratory.
He leads a large collaborative team of about a dozen Goddard personnel plus
co-investigators at about 18 academic, aerospace, and international external
institutions established for the Vision Mission Study and expanded, at a low
level of effort, in the following years.
Goddard's role is to continue to foster and coordinate the further development
of the science program goals and the mission architecture to satisfy those goals
and to pursue and encourage the development of the technologies needed to enable
the mission in the late 2020s.
