The Moon appears to be more yellowish near the horizon. This is for the same reason the Sun and/or sky appears to be orangey-red at sunrise/sunset. When the Moon appears near the horizon, the light coming from it has to pass through more layers of atmosphere. This scatters the blue away, and leaves yellow, orange, and red. [10]
The moon will gradually become more visible in the coming days, reaching its first-quarter stage by Jan. 6 and becoming a full moon by Jan. 13, according to NASA.
Surveyor 3 on the Moon. The first image returned by Luna 3 showed the far side of the Moon. This is a list of robotic space probes that have flown by, impacted, orbited or landed on the Moon for the purpose of lunar exploration, as well as probes launched toward the Moon that failed to reach their target.
The Moon's maximum and minimum declination vary because the plane of the Moon's orbit around Earth is inclined by about 5.14° with respect to the ecliptic plane, and the spatial direction of the Moon's orbital inclination gradually changes over an 18.6-year cycle, alternately adding to or subtracting from the 23.5° tilt of Earth's axis.
The Moon's elongation is its angular distance east of the Sun at any time. At new moon, it is zero and the Moon is said to be in conjunction. At full moon, the elongation is 180° and it is said to be in opposition. In both cases, the Moon is in syzygy, that is, the Sun, Moon and Earth are nearly aligned.
Diurnal libration is the small daily libration, an oscillation due to Earth's rotation, which carries an observer first to one side and then to the other side of the straight line joining Earth's and the Moon's centers, allowing the observer to look first around one side of the Moon and then around the other—since the observer is on Earth's ...
At this location the selenographic colongitude at sunrise is defined as 0°. Thus, by the time of the Full Moon the colongitude increases to 90°; at Last Quarter it is 180°, and at the New Moon the colongitude reaches 270°. Note that the Moon is nearly invisible from the Earth at New Moon phase except during a solar eclipse.
On 26 March 2019, Vice President Mike Pence announced that NASA's Moon landing goal would be accelerated by four years with a planned landing in 2024. [26] On 14 May 2019, NASA Administrator Jim Bridenstine announced that the new program would be named Artemis, after the goddess of the Moon in Greek mythology who is the twin sister of Apollo.
