Astronomical and Sortie Payload EVA Operations

Greater numbers of spacecraft and payloads are being developed for on-orbit astronomical viewing and data acquisition. Based on cost savings potentials, more consideration is now being given to on-orbit servicing and associated crew operations. Accordingly, integration of crew functions at program onset and continuing throughout the development phases becomes essential to aid in achieving mission success. Through cross coupling of these crew operations and associated equipment, simulations, and training with standard classes and families of spacecraft, substantial cost benefits to a variety of programs can be realized. Thus, can be established a logical and proven crew operations data and performance base for the future.
