Underneath their flight suits, the astronauts wore a biosensor suit that measured blood pressure, body temperature, respiration and heart rate. Film recorded during the flight was used for study of astronaut behavior in microgravity. However, only one of the twelve Gemini experiments addressed human life in space. The experiment examined the effects of radiation and microgravity on isolated human blood cells.
The inside of the Gemini capsule is very small—so small that the astronauts had to put on their space suits and open the capsule hatch if they wanted to stand up. While in space, they ate three freeze-dried meals a day, went to the bathroom using hoses and bags, and cleaned house just by opening the hatch—everything that wasn't attached was sucked out into space!
On the bottom of the craft, you can see the pattern that was burned into the heat shield when the capsule reentered the Earth's atmosphere. The outer surface vaporized from a solid to a gas. As it boiled away, it carried away heat. The black pattern on the heat shield is made of the carbon residue left behind.
The pattern isn't centered on the heat shield because the capsule came into the atmosphere at an angle. Entering at an angle gave the capsule some lift, like a wing. The commander could adjust the reentry flight path if needed.
Gemini 11 capsule Gemini 11 took astronauts Dick Gordon and Pete Conrad into space, setting an altitude record of miles 1, kilometers. Gemini 11 launch. History Project Gemini bridged the gap between the Mercury program, the first project to put an astronaut in space, and the Apollo program, which landed humans on the moon.
The official objectives of the program were: "To subject man and equipment to space flight up to two weeks in duration; To rendezvous and dock with orbiting vehicles and to maneuver the docked combination by using the target vehicle's propulsion system; To perfect methods of entering the atmosphere and landing at a predetermined point on land; To gain additional information concerning the effects of weightlessness on crew members and to record the physiological reactions of crew members during long duration flights.

The major objectives assigned to Gemini according to the Kennedy Space Center were: To test an astronaut's ability to fly long-duration missions up to two weeks in space.
To understand how spacecraft could rendezvous and dock in orbit around the Earth and the moon. To perfect re-entry and landing methods. To further understand the effects of longer space flights on astronauts A brief summary of the Gemini flight results reveals how successful the Gemini program was. Gemini V: August , first week-long flight, first fuel cells. Gemini IX-A: June , third rendezvous.
