This space paper model is a Space Capsule of Nasa’s Project Gemin, the papercraft is designed by T. Noteboom. A space capsule is an often manned spacecraft which has a simple shape for the main section, without any wings or other features to create lift during atmospheric reentry. Capsules have been used in most of the manned space programs to date, including the world’s first Vostok and Mercury manned spacecrafts, as well as in later Soviet Voskhod, Soyuz, Zond/L1, L3, TKS, US Gemini, Apollo, Chinese Shenzhou and currently developing US, Russia, India manned spacecrafts. A capsule is the specified form for the Crew Exploration Vehicle.
Gemini capsule was built in 1961 and the first capsule was delivered in 1963. The spacecraft was 19 feet long and 10 feet wide with a launch weight of 8,490 pounds. The Gemini capsule first flew with a crew on March 23, 1965.
Gemini was the first manned spacecraft to include an onboard computer, the Gemini Guidance Computer, to facilitate management and control of mission maneuvers. Unlike the Mercury, it used ejection seats, in-flight radar and an artificial horizon – devices similar to those used in the aviation industry.
Unlike Mercury, which could only rotate around the axes of pitch, yaw, and roll to change its orientation in space, the Gemini spacecraft was designed also to translate in all three perpendicular axes, and also to alter its orbital inclination and altitude. It used these capabilities to dock with the Agena target vehicle, which had its own rocket engine which could be used to perform larger altitude changes.
A major difference between the Gemini and Mercury spacecraft was that Mercury had all systems other than the reentry rockets situated within the capsule, most of which were accessed through the astronaut’s hatchway. In contrast, Gemini housed power, propulsion, and life support systems in a detachable Equipment Module located behind the Reentry Module, which made it similar to the Apollo Command/Service Module design. Many components in the capsule itself were reachable through their own small access doors.
The original intention was for Gemini to land on solid ground instead of at sea, using a Rogallo wing rather than a parachute, with the crew seated upright controlling the forward motion of the craft. To facilitate this, the airfoil did not attach just to the nose of the craft, but to an additional attachment point for balance near the heat shield. This cord was covered by a strip of metal which ran between the twin hatches. This design was ultimately dropped, and parachutes were used to make a sea landing as in Project Mercury. The capsule was suspended at an angle closer to horizontal, so that a side of the heat shield contacted the water first. This eliminated the need for the landing bag cushion used in the Mercury capsule.
Early short-duration missions had their electrical power supplied by batteries; later endurance missions used the first fuel cells in manned spacecraft.
Project Gemini was the second human spaceflight program of NASA, the civilian space agency of the United States government. Project Gemini was conducted between projects Mercury and Apollo, with ten manned flights occurring in 1965 and 1966.
Its objective was to develop space travel techniques in support of Apollo, which had the goal of landing men on the Moon. Gemini achieved missions long enough for a trip to the Moon and back, perfected extra-vehicular activity, and orbital maneuvers necessary to achieve rendezvous and docking. All manned Gemini flights were launched from Cape Canaveral, Florida using the Titan II GLV launch vehicle. [Source: Wiki]
