Space missions
**Going though the missions of humans from Earth to Space

Project Mercury :
It begun in 1958 and was completed in 1963.
It was the 1st U.S program to establish a human presence in space. The objectives of the program, which made 6 human flights from 1961 to 1963, were:
[*To successfully orbit a manned spacecraft around Earth
*To investigate humankinds' ability to function in space
*To recover both occupant and spacecraft.]
Each Mercury spacecraft carried one astronaut. There were seven Mercury astronaut, all military test pilots. Six of them flew aboard the Mercury
Spacecraft. ( the six are: Alan Shepard, Gus Grissom, Gordon Cooper, and Wally Schirra )
The seventh, Duke Slayton, was grounded due to a minor medical ailment but eventually flew as a crewman aboard the Apollo-Soyuz Test Project in 1975.

Apollo 11:
Apollo 11 was the spaceflight that landed the first humans on the Moon, Americans Neil Armstrong and Buzz Aldrin, on July 20, 1969, at 20:18. Neil Armstrong became the first to step onto the lunar surface six hours later on July 21 at 02:56. Together they collected 47.5 pounds of lunar material for return to Earth. The third member of the mission, Michael Collins, piloted the command spacecraft alone in lunar orbit until  Apollo spacecraft had three parts: a Command Module with a cabin for the three astronauts, and the only part that landed back on Earth; a Service Module which supported the Command Module with propulsion, electrical power, oxygen, and water; and a Lunar Module for landing on the Moon. They returned to Earth and landed in the Pacific Ocean on July 24.

Project Gemini:
Project Gemini was NASA's second human space flight program. It happened in between Project Mercury and Apollo 11. Its objective was to develop space travel techniques to support Apollo's mission to land astronauts on the moon. Gemini achieved missions long enough for a trip to the moon  and back; perfected working outside the spacecraft with extra- vehicular and pioneered the orbital manevuversion necessary to achieve rendezuous and docking.
