What is the Gemini project?

The Gemini project was the second American space program with a crew. Its primary goal was to develop the techniques and equipment needed for later landing of the Moon during the Apollo program. The capsules used for the Gemini project could accommodate two astronauts, stay in orbit for up to two weeks, make space flights and dock with another spacecraft. The Gemini project eventually included eleven crew missions that tested things such as endurance, docking and maneuvering in space.

The Gemini spacecraft project was launched on the Titan II, a transferred intercontinental ballistic missile. Titan II used hypergolic fuels, hydrazine and nitrogen tetroxide that are ignited in contact. The capsules themselves for the Gemini project were much smaller than the Apollo capsules, and in very cramped conditions it was able to hold only two astronauts. The size of the spacecraft was limited by matter that could be lowered in orbit, as well as the need to enter the capsule safely.

GEMINI KEOAPSLE was the first to include removable modules; It included a service module for fuel, power supply and life support, a module of re -entering the capsule and returning to the ground, and a command module for astronauts. Gemini capsules could use missiles to control their movement around the ground and often maneuver in a pre -planned orbit to meet another vehicle. Originally, batteries were used for power supply, but in later missions were added fuel cells with oxygen in hydrogen, the first fuel cells that were summer on a spacecraft with a crew.

Later Gemini missions have shown the protocols for circulating in orbit and using an anchored Agena missile to increase the higher orbit. Extra vehicular activity (EVA), commonly known as "Space Walking", was first used on the Gemini project to work on the outside of the spacecraft. The Gemini Astronauts project eventually remained up to two tRescue in Space, verifies that the human body and spacecraft equipment could last during a long voyage to the Moon. After completing the Apollo project, a larger version of the Gemini spacecraft for ferry supplies and people into space was designed, but the plan was later eliminated.
