Potential astrophysics science missions enabled by NASA's planned Ares V

NASA's planned Ares V cargo launch vehicle with its 10 m diameter fairing and ~60,000 kg payload mass to L2 offers the potential to launch entirely new classes of missions, such as 8-m monolithic aperture telescopes, 12- to 16-m aperture x-ray telescopes, 16- to 24-m segmented telescopes and highly capable outer planet missions. This paper summarizes the current Ares V baseline performance and reviews potential mission concepts enabled by these capabilities.
