Background:

The Review of United States Human Space Flight Plans Committee (also known as the Augustine Committee) was a group reviewing the human spaceflight plans of the United States. Their goal was to ensure the nation is on “a vigorous and sustainable path to achieving its boldest aspirations in space.” The review was announced by the Office of Science and Technology Policy (OSTP) on May 7, 2009. It covered human spaceflight options after the time NASA planned to retire the space shuttle. A summary report was provided to the OSTP Director John Holdren and NASA administrator Charles Bolden on Sept. 8, 2009. The report was publically released on Oct. 22, 2009.

Value Added:

In support of the Human Spaceflight Commission, Aerospace prepared the Human Rated Delta IV Heavy Constellation Impact Study Report to examine the nation’s vision for future human space exploration. The Human Rated Delta IV Heavy Study assessed the technical, cost, and schedule feasibility of replacing the Ares I with a human-rated Delta IV Heavy, and its effect on the overall Constellation architecture. This study examined the impacts to a Shuttle Derived Heavy Lift Vehicle capability, such as the Ares V. It also examined the impacts to the Orion crew vehicle and the solid rocket motor industrial base, as well as the capabilities for exploration beyond low Earth orbit (LEO). Additionally, Aerospace assessed the impacts on national security space if NASA replaces Ares I with a human-rated version of Delta IV H for low Earth orbit human missions. This report was briefed to NASA senior leadership in March 2009. Subsequently, Gary Pulliam, supported by Ray Johnson, briefed the publicly releasable Executive Summary of the Human Rated Delta IV Heavy Study to the committee. The committee asked for further written detail behind the development schedule for the Human Rated Delta IV Heavy Vehicle and the impacts of replacing Ares I on the solid rocket motor industrial base. Aerospace used information available in the full report and other sources to prepare a detailed response to the committee. Aerospace’s Human Rated Delta IV Heavy Constellation Impact Study technical operating report was publicly released in August 2009.
