Over the past four years SSG has been working with the support of JPL to develop light weight, high performance optical systems for earth orbit and deep space missions. These programs, which include both ground demonstrations and flight instruments, achieve the improved weight and performance through a combination of two main features: multifunctional design and silicon carbide optics and structures. Multifunctional designs include aperture sharing telescopes and spectrometers that not only perform science, but can be used for optical navigation and laser communication. SiC, in monolithic form for optics and in composite form for fracture-tough structures, enables very light weight systems that are passively athermal to cryogenic temperatures. Ground demonstrations of several of these technologies have led to the upcoming flight demonstrations on DS-1 and EO-1, as well as candidate telescopes for other technology flights. These advances are currently being extended to the next level of multifunctionality in a sensorcraft demonstration, in which a SiC telescope performs science, optical navigation, and optical communication, while the structure serves as both the telescope bench and spacecraft bus. This paper presents a general discussion of multifunctional designs and SiC optical systems in the context of recent, present, and future work.
