Because of the precession of the lunar orbit, each year different stars are occulted.

Of these, 24 people have traveled beyond Low Earth orbit, to either lunar or trans lunar orbit or to the surface of the moon three of the 24 did so twice Jim Lovell, John Young and Eugene Cernan.

On the first lunar swing by, Hiten released a small orbiter, Hagoromo (named after the feather mantle of Hiten ), into lunar orbit.

For ten days, the astronauts put both Apollo spacecraft through their paces in Earth orbit, including an undocking and redocking of the lunar lander with the command vehicle, just as the landing mission crew would perform in lunar orbit.

Zond 3 proceeded on a Mars trajectory, but not at a time when planetary encounter would occur.

December 24 Apollo program U.S. spacecraft Apollo 8 enters orbit around the Moon.

Wernher von Braun initially pushed for a flight engineering concept that called for an Earth orbit rendezvous technique (the approach he had argued for building his space station), but in 1962 he converted to the lunar orbit rendezvous concept that was subsequently realized.

Grey remains in orbit aboard the Freedom command module while Walker and Anderson land on the moon in the lunar module Liberty .

The Moon's orbit is subtly perturbed by the Sun and Earth in many small, complex and interacting ways.

The Apollo Extension Series ( Apollo X ,) proposed up to 30 flights to Earth orbit, using the space in the Spacecraft Lunar Module Adapter (SLA) to house a small orbital laboratory (workshop).

The 18.6 year nodes cycle also has an influence when the ascending node of the lunar orbit is in the vernal equinox, the lunar declination can go as far as 28 each month.

The Apollo Lunar Module (LM), originally designated the Lunar Excursion Module (LEM), was the lander portion of the Apollo spacecraft built for the US Apollo program by Grumman Aircraft to carry a crew of two from lunar orbit to the surface and back.

At first called the Lunar Circle, Lunar Society became the formal name by 1775.

Apollo 9 was the third manned mission in the United States Apollo space program and the first flight of the Command Service Module (CSM) with the Lunar Module (LM).

Service Propulsion System The SPS engine was used to place the Apollo spacecraft into and out of lunar orbit, and for mid course corrections between the Earth and Moon.

The term eclipse is most often used to describe either a solar eclipse, when the Moon's shadow crosses the Earth's surface, or a lunar eclipse, when the Moon moves into the Earth's shadow.

Did you see the lunar eclipse yesterday?

The European spacecraft SMART 1 , the second ion propelled spacecraft, was in lunar orbit from 15 November 2004 until its lunar impact on 3 September 2006, and made the first detailed survey of chemical elements on the lunar surface.

She drives her moon chariot across the heavens.

The photos covered 19,000,000 km² of the lunar surface.

The LK (, from Lunniy Korabl , lunar ship ) was a piloted lunar lander developed in the 1960s as a part of the Soviet attempts at human exploration of the Moon.

We learn about its orbit, the period of its orbit and so on.

In China, they celebrate New Year by the lunar calendar.

The crater Ångström on the Moon is named in his honour.

A lunar crater was named after Dalton.

For testing purposes, satellites in low earth orbit have been destroyed by ballistic missiles launched from earth.

Privately funded lunar exploration has been promoted by the Google Lunar X Prize, announced 13 September 2007, which offers US 20 million to anyone who can land a robotic rover on the Moon and meet other specified criteria.

However, because Earth is moving in its orbit around the Sun at the same time, it takes slightly longer for the Moon to show the same phase to Earth, which is about 29.5 days (its synodic period).

Sirius has an elliptical orbit.

For example, see the isotopes of bismuth.

Josephus tells us that Herod died after a lunar eclipse.

The half silvered sphere of the moon also shows the Lunar phase.

We call this the orbiting mode.

This is a picture here taken from orbit.

As it arrived, the spacecraft did not go into orbit around the asteroid, but remained in a station keeping heliocentric orbit close by.

A lunar month is shorter than a calendar month.

A lunar month is shorter than a calendar month.

The lunar month is shorter than the calendar month.

The 30 day month is an approximation of the lunar cycle.

Ida is the introverted, lunar nadi, and refers to the right hemisphere of the brain.

In 1958, Oberth was back in Feucht, Germany, where he published his ideas on a lunar exploration vehicle, a lunar catapult , and on muffled helicopters and airplanes.

At the shorter extreme, Encke's Comet has an orbit that does not reach the orbit of Jupiter, and is known as an Encke type comet.

Another hypothesis suggests that its orbit may be evidence for a large planet beyond the orbit of Neptune.
