The side of the orbit of the moon that is closest to the Earth is the lunar perigee.
Mercury . . . carried one astronaut at a time, into low earth orbit. Gemini . . . carried two astronauts at a time, into low earth orbit. Apollo . . . carried three astronauts at a time, into low earth orbit, trans-lunar injection, lunar orbit, and two of them to a lunar landing.
the first test of lunar module in lunar orbit was in 1964 using Apollo10, the space craft, sent by the USA sorry if this isnt a good answer :(

No. The moon's orbit is tilted by about 5 degrees relative to Earth's orbit around the sun. This is why we do not see eclipses every month.
The moon's orbit is inclined about 51/2 degrees relative to the plane of the Earth's orbit. For one thing, this explains why we don't have a lunar eclipse at every Full Moon, and a solar eclipse at every New Moon.

The relative concentration of elements on lunar surface compared to earth's surface is known as regolith.

No. A lunar eclipse occurs when the Earth passes between the Sun and Moon. Earth's orbit is an intangible imaginary ellipse that does not cast a shadow.

The Moon, Sun and Earth are not perfectly aligned every month. Therefore there is not an eclipse every full Moon. The reason the alignment is usually not perfect is that the Moon's orbit is tilted relative to the plane of the Earth's orbit around the Sun.

The earth's orbit of the sun and the moon's orbit of the earth are not on the same plane; one of the two orbits is tilted about five degrees with respect to the other, so the moon usually misses the earth's shadow.
why does a lunar or solar eclipse not occurs every month?
The Moon itself is nearly circular, as is its orbit around the Earth. Lunar perigee (the point in the orbit nearest the Earth) is 363,104 km (225,622 miles) Lunar apogee (the point farthest from the Earth) is 405,696 km (252,087 miles) This gives an elliptical eccentricity of 0.054 (So technically, the orbit is an ellipse.)
