The Exploration Systems Architecture Study (ESAS) is the official title of a large-scale, system level study released by the National Aeronautics and Space Administration (NASA) in November 2005 in response to American president George W. Bush's announcement on January 14, 2004 of his goal of returning astronauts to the Moon and eventually Mars — known as the Vision for Space Exploration (and unofficially as "Moon, Mars and Beyond" in some aerospace circles, though the specifics of a manned "beyond" programme remain vague).

“For women who do not love us, as for the “disappeared”, knowing that we no longer have any hope does not prevent us form continuing to wait.

—Marcel Proust (1871–1922)

—Hannah Arendt (1906–1975)

—Ralph Waldo Emerson (1803–1882)
“It’s worth living abroad to study up on genteel and delicate manners. The maid smiles continuously; she smiles like a duchess on a stage, while at the same time it is clear from her face that she is exhausted from overwork.”
—Anton Pavlovich Chekhov (1860–1904)
