The Mercury Program Essay, Research Paper
Project Mercury, the first manned U.S. space project, became an official NASA program
on October 7, 1958. The Mercury Program was given two main but broad objectives: 1. to
investigate man s ability to survive and perform in the space environment and 2. to develop basic
space technology and hardware for manned space flight programs to come.
NASA also had to find astronauts to fly the spacecraft. In 1959 NASA asked the U.S.
military for a list of their members who met certain qualifications. All applicants were required to
have had extensive jet aircraft flight experience and engineering training. The applicants could be
no more than five feet eleven inches tall, do to the limited amount of cabin space that the Mercury
modules provided. All who met these requirements were also required to undergo numerous
intense physical and psychological evaluations. Finally, out of a field of 500 people who met the
experience, training, and height requirements, NASA selected seven to become U.S. astronauts.
There names, Lieutenant M. Scott Carpenter; Air Force Captains L. Gordon Cooper, Jr., Virgil
Gus Grissom, and Donald K. Deke Slayton; Marine Lieutenant Colonel John H. Glenn, Jr.;
and Navy Lieutenant commanders Walter M. Schirra, Jr., and Alan B. Shepard, Jr. Of these, all
flew in Project Mercury except Deke Slayton who was grounded for medical reasons. He later
became an American crewmember of the Apollo-Soyuz Test Project.
The Mercury module was a bell shaped craft. Its base measured exactly 74.5 inches wide
and it was nine feet tall. For its boosters NASA chose two U.S. military rockets: the Army s
Redstone, which provided 78,000 pounds of thrust, was used for suborbital flights, and the Air
Force Atlas, providing 360,000 pounds of thrust, was used for orbital fights. The Mercury craft
was fastened to the top of the booster for launch. Upon reaching the limits of Earth s atmosphere
the boosters were released from the module, and fell into uninhabited ocean.
The first Mercury launch was performed on May 5, 1961. The ship, Freedom 7, was the
first U.S. craft used for manned space flight. Astronaut Alan Shepard, Jr. remained in suborbital
flight for 15 minutes and 22 seconds, with an accumulated distance of 116 miles.
The second and final suborbital mission of the Mercury Project was launched on July 21,
1961. Gus Grissom navigated his ship, Liberty Bell 7, through flight for just 15 seconds longer
than the previous mission.
The next Mercury flight was accomplished using an Atlas booster. On February 20,1962
it fired up and launched John Glenn, Jr., inside Friendship 7, into orbit. Glenn orbited Earth three
times and when he returned the country celebrated.
Just three months later on May 24 Scott Carpenter also orbited Earth three times in Aurora
On October 3, 1962 Walter Schirra, Jr. entered Earth s orbit in his ship, Sigma 7. He
completed 6 orbits and then completed the first splashdown in the Atlantic Ocean. All previous
splashdowns and recoveries were performed in the Pacific.
The final Mercury mission was the longest. Launched into orbit on May 15, 1963, Faith 7,
with Gordon Cooper, Jr. inside, went around Earth 22 times in 34and a half hours. On May 16 it
too splashed down in the Atlantic Ocean where it was recovered, successfully ending the Mercury
The Mercury Project, five years and $392.6 million dollars after it began, came to a close.
The entire project was highly successful, achieving both of its goals. It paved the way for the next
generation of NASA spacecraft: Gemini.
