Perigee 160. A nautical mile or sea mile is a unit of Length. It corresponds approximately to one minute of Latitude along any meridian. In Physics, an orbit is the gravitationally curved path of one object around a point or another body for example the gravitational orbit of a planet around a star In Celestial mechanics, an apsis, plural apsides (ˈæpsɨdɪːz is the point of greatest or least distance of the Elliptical orbit of an object from 5 kilometres (86. 7 nmi) (1st orbit)

Objectives

With Apollo looming on the horizon, Gemini project managers wanted to accomplish a rendezvous immediately after reaching orbit, just as it would have to be done around the Moon.

The Agena (designated RM-81 by the USAF) was a rocket upper stage developed by Lockheed for the ill-fated WS-117L US Reconnaissance satellite Conrad had originally hoped for a Gemini flight around the Moon, but had to settle for the highest Earth orbit ever reached by an American manned spacecraft (1374 kilometer altitude). Gordon's first space-walk once again proved more difficult than ground simulations, and had to be cut short when he became overtired. Extra-vehicular activity ( EVA) is work done by an Astronaut away from the Earth and outside of a Spacecraft. A second, two-hour "stand-up" space walk went more smoothly: Gordon even fell asleep while floating halfway out the hatch. An experiment to link the Agena and Gemini vehicles with a 30 meter tether (which Gordon had attached during his space-walk) and rotate the joined pair was troublesome. Conrad had problems keeping the tether taut, but was able to generate a modicum of "artificial gravity. " The mission ended with the first totally automatic, computer-controlled reentry by the U. S. , which brought Gemini XI down only 4. 5 kilometers from its recovery ship.

Experiments

An Atlas launch vehicle launches GATV-5006 into orbit for the Gemini 11 mission.
An Atlas launch vehicle launches GATV-5006 into orbit for the Gemini 11 mission. The SM-65 Atlas was a missile built by the Convair Division of General Dynamics. In Spaceflight, a launch vehicle or carrier rocket is a Rocket used to carry a payload from the Earth's surface into Outer space.

The 12 scientific experiments were (1) synergistic effect of zero-g and radiation on white blood cells, (2) synoptic terrain photography, (3) synoptic weather photography, (4) nuclear emulsions, (5) airglow horizon photography, (6) UV astronomical photography, (7) Gemini ion wake measurement, and (8) dim sky photography. Weightlessness is a phenomenon experienced by people during Free-fall.

Reentry

The reentry was the first computer-controlled reentry in the US space program. They landed only 4. 5 km away from the intended landing site and were recovered by USS Guam.

The Gemini 11 mission was supported by the following U. S. Department of Defense resources; 9,054 personnel, 73 aircraft and 13 ships.

Insignia

On the Gemini 11 crew insigina, stars are used to mark the major milestones of the mission. The first orbit Agena rendezvous is marked by a small gold star just above the earth, to the left. The Agena docking is marked by a large star on the left. The star at the top marks the record high apogee (1,374 km) reached by Gemini 11. Finally the star on right marks Dick Gordon's spacewalk. The docking, record apogee and spacewalk are also shown on the patch by the Agena, orbital apogee path and spacewalking astronaut. The patch is done in US Navy colors, blue and gold. Conrad and Gordon were both members of the US Navy.

Capsule location

The capsule is on display at the California Science Center in Los Angeles, California. The California Science Center (sometimes spelled California ScienCenter) is a state agency and museum located in Exposition Park, Los Angeles Los Angeles (lɑˈsændʒələs los ˈaŋxeles in Spanish) is the largest City in the state of California and the American West
