Circumlunar Trajectory
A circumlunar trajectory, trans-lunar trajectory or lunar free return is a type of free return trajectory which takes a spacecraft from Earth, around the far side of the Moon, and back to Earth using only gravity once the initial trajectory is set. Background[edit] The first spacecraft to fly a circumlunar trajectory was Luna 3. Circumlunar trajectories were also used by Apollo missions prior to lunar orbit insertion,[1] to provide a free return to Earth in the event of a propulsion system malfunction on the way to the Moon

race. It was based on the Soyuz 7K-OK[1] with several components stripped out to reduce the vehicle weight. The most notable modifications included the removal of the orbital module (the orbital module was replaced by a support cone and a high-gain parabolic antenna) and a reserve parachute; and the addition of the gyro platform and star navigation sensors for the far space navigation. The spacecraft was capable of carrying two cosmonauts

Far Side Of The Moon
The far side of the Moon, sometimes figuratively known as the dark side of the Moon, is the hemisphere of the Moon
Moon
that always faces away from Earth. The far side's terrain is rugged, with a multitude of impact craters and relatively few flat lunar maria. It has one of the largest craters in the Solar System, the South Pole–Aitken basin. Although both sides of the Moon
Moon
experience two weeks of sunlight followed by two weeks of night, the far side is sometimes called the "dark side of the Moon," with "dark" meaning "unseen" rather than lack of light.[1][2][3][4] About 18% of the far side is occasionally visible from Earth

due to libration. The remaining 82% remained unobserved until 1959, when the Soviet Union's Luna 3

to carry a crew of two from lunar orbit to the surface and back. Designed for lunar orbit rendezvous, it consisted of an ascent stage and descent stage, and was ferried to lunar orbit by its companion Command/Service Module (CSM), a separate spacecraft of approximately twice its mass, which also took the astronauts home to Earth. After completing its mission, the LM was discarded. It was capable of operation only in outer space; structurally and aerodynamically it was incapable of flight through the Earth's atmosphere. The Lunar Module was the first manned spacecraft to operate exclusively in the airless vacuum of space

Spacecraft
used for human spaceflight carry people on board as crew or passengers from start or on orbit (space stations) only, whereas those used for robotic space missions operate either autonomously or telerobotically.

Centaur (rocket Stage)
Centaur is a rocket stage designed for use as the upper stage of space launch vehicles and is currently used on the Atlas V. Centaur was the world's first high-energy[clarification needed] upper stage, burning liquid hydrogen (LH2) and liquid oxygen (LOX), and has enabled the launch of some of NASA's most important scientific missions over its 50-year history. Centaur was the brainchild of Karel J. "Charlie" Bossart (the man behind the Atlas ICBM) and Dr. Krafft A. Ehricke, both Convair employees.[3] Their design was essentially a smaller version of the Atlas, with its concept of using lightweight "stainless steel balloon" tanks whose structural rigidity was provided solely by the pressure of the propellants within

Trans-lunar Injection
A trans-lunar injection (TLI) is a propulsive maneuver used to set a spacecraft on a trajectory that will cause it to arrive at the Moon. Typical lunar transfer trajectories approximate Hohmann transfers, although low-energy transfers have also been used in some cases, as with the Hiten
Hiten
probe.[1] For short duration missions without significant perturbations from sources outside the Earth- Moon
Moon
system, a fast Hohmann transfer is typically more practical. A spacecraft performs TLI to begin a lunar transfer from a low circular parking orbit around Earth. The large TLI burn, usually performed by a chemical rocket engine, increases the spacecraft's velocity, changing its orbit from a circular low Earth
Earth
orbit to a highly eccentric orbit
