Paper Abstract
Over the last two years, we have studied system concepts for the International X-ray Observatory (IXO) with the goal of
increasing the science return of the mission and to reduce technical and cost risk. We have developed an optical bench
concept that has the potential to increase the focal length from 20 to 25 m within the current mass and stability
requirements. Our deployable bench is a tensegrity structure formed by two telescoping booms (compression) and a
hexapod cable (tension) truss. This arrangement achieves the required stiffness for the optical bench at minimal mass
while employing only high TRL components and flight proven elements. The concept is based on existing elements, can
be fully tested on the ground and does not require new technology.
Our design further features hinged, articulating solar panels, an optical bench fully enclosed in MLI and an instrument
module with radially facing radiator panels. We find that our design can be used over a wide range of sun angles, thereby
greatly increasing IXO's field of regard, without distorting the optical bench. This makes a much larger fraction of the
sky instantaneously accessible to IXO.
