The far side of the Moon, with Mare Marginis and Mare Smythii visible, photographed by Apollo 16 in 1972. It is much more cratered than the near side of the Moon. On 26 April 1962, NASA's Ranger 4 space probe became the first spacecraft to impact the far side of the Moon, although it failed to return any scientific data before impact. [34]
Mercury is visible as a black dot below and to the left of the center. The dark area above the center of the solar disk is a sunspot. The antumbra (from the Latin ante "before" and umbra "shadow") is the region from which the occluding body appears entirely within the disc of the light source.
Clementine's camera reveals (from right to left) the Moon lit by earthshine, the Sun's glare rising over the Moon's dark limb, and the planets Saturn, Mars, and Mercury (the three dots at lower left). Planetshine is the dim illumination, by sunlight reflected from a planet, of all or part of the otherwise dark side of any moon orbiting the body.
Trailers make “Fly Me to the Moon” look cute at best, when in fact it’s quite clever: a smarter-than-it-sounds, space-age sparring match of the Rock Hudson/Doris Day variety, in which the ...
In the summer, the moon is closer to the celestial equator, as well as Earth's horizon due to the tilt of the planet's axis. This is why we see more vibrant-colored moons in the summer.
The poles of the Moon are therefore in the dark for half a draconic year (or with only part of the Sun visible) and then lit for half a draconic year. The amount of sunlight falling on horizontal areas near the poles depends on the altitude angle of the Sun. But these "seasons" have little effect in more equatorial areas.
Lunar Crater Radio Telescope 3D conceptual design Concept of operations for building LCRT. The Lunar Crater Radio Telescope (LCRT) is a proposal by the NASA Institute for Advanced Concepts (NIAC) to create an ultra-long-wavelength (that is, wavelengths greater than 10 m, corresponding to frequencies below 30 MHz) radio telescope inside a lunar crater on the far side of the Moon.
The ages of the mare basalts have been determined both by direct radiometric dating and by the technique of crater counting.The radiometric ages range from about 3.16 to 4.2 billion years old (Ga), [4] whereas the youngest ages determined from crater counting are about 1.2 Ga. [5] Updated measurements of samples collected by the Chang’e-5 mission show that some lunar basalts could be as ...
