* [[Mercury 4]][[July 21]], [[1961]] -- "Liberty Bell 7": Suborbital flight. Astronaut: [[Virgil Grissom|Virgil (Gus) Grissom]]. The flight was identical to Shepard's, but an accident upon spashdown caused the loss of the spacecraft when it filled with seawater. Grissom escaped unhurt. Substantial controversy ensued as Grisson reported that the hatch had blown prematurely without his authorization. Engineering teams concluded this was unlikely. Mrs. Grissom was not invited to the White House as per a forming tradion with previous Astronaut Wives upon successful mission completion. Subsequent independent technical review of the incident has raised doubts as to the veracity of the incident report conclusions that Grissom blew the hatch and was responsible for the loss of the spacecraft. |

The Mercury program was a manned spaceflight program undertaken by the United States of America, conducted during the years (1959-1963). It was devoted to the goal of putting a man in orbit around the Earth. It was followed by the Gemini and Apollo programs.
Mercury spacecraft were one-man spacecraft. They were very cramped; it was said that the Mercury spacecraft were not ridden, they were worn.
The program included 20 unmanned launches. Not all of these were intended to reach space and not all were successful in their objectives. The fifth flight in 1959 launched a monkey named Sam into space. Other space-farers were Miss Sam the monkey and Ham and Enos, both chimpanzees.
The name Mercury comes from the Roman god (it is also the name of the innermost planet of the solar system).
Six manned flights took place under the Mercury program:
A seventh flight was cancelled when astronaut Deke Slayton was disqualified for medical reasons.
