At that time NASA was still debating placing a chimpanzee in orbit as part of the Mercury-Atlas subprogram, with NASA headquarters questioning the wisdom of the Manned Spacecraft Center launching another unmanned Mercury mission. The NASA Public Affairs Office issued a press release stating "The men in charge of Project Mercury have insisted on orbiting the chimpanzee as a necessary preliminary checkout of the entire Mercury program before risking a human astronaut." prior to the flight.

Famous quotes containing the word history:
“He wrote in prison, not a History of the World, like Raleigh, but an American book which I think will live longer than that. I do not know of such words, uttered under such circumstances, and so copiously withal, in Roman or English or any history.”
—Henry David Thoreau (1817–1862)
“A poet’s object is not to tell what actually happened but what could or would happen either probably or inevitably.... For this reason poetry is something more scientific and serious than history, because poetry tends to give general truths while history gives particular facts.”
—Aristotle (384–323 B.C.)
“The history of all hitherto existing society is the history of class struggles.”
—Karl Marx (1818–1883)
