Slide 2
Warm-up In 3-5 sentences write what you know about the three
main space missions. To refresh your mind, the three we are talking
about are Mercury, Gemini, and Apollo.
Slide 3
Objectives Understand the three different space missions and
what they did throughout their time.
Slide 4
Project Mercury Initiated in 1958, completed in 1963 Project
Mercury was the United States' first man-in-space program.
Slide 5
Mercury Objectives The objectives of the program was to Orbit a
manned spacecraft around Earth To investigate man's ability to
function in space To recover both man and spacecraft safely
Slide 6
Requirements for Spacecraft The spacecraft must be fitted with
a reliable launch-escape system to separate the spacecraft and its
crew from the launch vehicle in case of impending failure. The
pilot must be given the capability of manually controlling
spacecraft attitude. The spacecraft must carry a retrorocket system
capable of reliably providing the necessary impulse to bring the
spacecraft out of orbit. A zero-lift body utilizing drag braking
would be used for reentry. The spacecraft design must satisfy the
requirements for a water landing.

Project Mercury Astronauts Lieutenant Commander Alan Shepard
(U.S. Navy) Captain Virgil I. (Gus) Grissom (U.S. Air Force)
Captain Leroy G. (Gordon) Cooper (U.S. Air Force) Lieutenant
Commander Walter M. Schirra (U.S. Navy) Captain Donald K. (Deke)
Slayton (U.S. Air Force) Lieutenant Colonel John H. Glenn (U.S.
Marine Corps) Lieutenant Malcolm S. (Scott) Carpenter (U.S. Navy)
Top row (L-R): Shepard, Grissom, Cooper Bottom row (L-R): Schirra,
Slayton, Glenn, Carpenter
Slide 8
Mercury Spacecraft one-shaped one-man capsule with a cylinder
mounted on top. The blunt end was covered with an ablative heat
shield to protect it against the 3,000 degree heat of entry into
the atmosphere. The dimension of it were 6.5 feet long and 6.2 feet
in diameter.

Slide 10
Project Gemini The second U.S. manned space program that was
announced in January 1962.
Slide 11
Project Gemini - Goal To subject two men and supporting
equipment to long duration flights -- a requirement for projected
later trips to the moon or deeper space. To perfect methods of
entering the atmosphere and landing at a preselected point on land.
To rendezvous and dock with orbiting vehicles and to maneuver the
docked combination by using the target vehicle's propulsion system
To gain additional information concerning the effects of
weightlessness on crew members and physiological reactions of crew
members during long duration flights. To provide the astronauts
with zero-gravity, rendezvous, and docking experience required for
Apollo
Slide 12
Project Gemini Spacecraft 5.8 meters long 3 meters in diameter
3180 kilograms (8400 pounds) It was designed as a two-man
spacecraft
Slide 13
Gemini Astronauts The Sixteen Astronauts Neil A. Armstrong,
Frank Borman, Charles 'Pete' Conrad, Jr, James A. Lovell, Jr, James
A. McDivitt, Elliot M. See, Thomas J. Stafford, Edward H. White II,
and John W.Young

Slide 15
Apollo The Apollo program was the third human spaceflight
program by NASA.
Slide 16
Apollo Objectives To establish the technology to meet other
national interests in space. To achieve preeminence in space for
the United States To carry out a program of scientific exploration
of the Moon To develop man's capability to work in the lunar
environment.
Slide 17
Apollo Spacecraft Command Module - designed to carry three
astronauts from launch to lunar orbit and back to an Earth ocean
landing. 11.42 feet tall 12.83 feet in diameter 12,250 pounds
Service Module it supported the command Module, with a service
propulsion engine and an RCS with propellants, and a fuel cell
power generation system with liquid hydrogen and liquid oxygen
reactants. 24.6 feet long 12.83 feet in diameter Weighed just over
54,000 pounds
Slide 18
Apollo Spacecraft Landing on the Moon Lunar Module - was
designed to descend from lunar orbit to land two astronauts on the
Moon and take them back to orbit to rendezvous with the Command
Module (Neil Armstrongs crew was the first to actually do the lunar
landing and walk on the moon on their mission, making Neil
Armstrong the first man to walk on the moon.)

the goals of the three space missions.
