On April 26th and 27th, 2008, NASA Ames Research Center hosted a two-day weekend workshop entitled "Astronomy Enabled by Ares V.” The primary goal of the workshop was to begin the process of bringing the Ares V designers together with senior representatives of the astronomical community to discuss the feasibility of using the Ares V heavy-lift launch vehicle to enable both new astronomical telescope architectures and new science. When developed in the latter part of the upcoming decade Ares V will be by far the most capable launch vehicle, with mass and volume launch capability many times that now available. The vehicle is understood to be the main workhorse in carrying humans and cargo to the Moon and beyond and, as such, is a key lynchpin for NASA's new space transportation architecture. Participants included experts from academia, industry, and NASA, including representatives of the Constellation architecture. Participants considered, in the context of identified astronomy needs: (1) Are there telescope concepts or missions capable of breakthrough science that are either enabled or significantly enhanced by the capabilities of an Ares V? (2) What demands do large telescopes place on the payload environment of the Ares V, such as mass, volume, fairing shape, cleanliness, acoustics, etc.? (3) What technology and environmental issues need to be addressed to facilitate launching observatories on an Ares V? (4) Is there a trade-off between mass and complexity that could reduce launch risk and, thereby, the cost of building large telescopes? We report on the results of this workshop, which included discussion on the operations model for such large-investment astronomical facilities. Such an operations model might well involve human and or robotic maintenance and servicing, in order to fully capitalize on the science potential of such facilities.
