Few reports concerning these phenomena are ever published in peer reviewed scientific journals, and rightfully or wrongfully, the lunar scientific community rarely discusses these observations. Most lunar scientists will acknowledge that transient events such as outgassing and impact cratering do occur over geologic time : the controversy lies ...
The orbits of the Moon and planets are integrated numerically along with the orientation of the Moon called physical libration. [23] At the Moon's surface, the beam is about 6.5 kilometers (4.0 mi) wide [24] [i] and scientists liken the task of aiming the beam to using a rifle to hit a moving dime 3 kilometers (1.9 mi) away. The reflected light ...
The most significant improvement of position observations of the Moon have been the Lunar Laser Ranging measurements, obtained using Earth-bound lasers and special retroreflectors placed on the surface of the Moon. The time-of-flight of a pulse of laser light to one of the retroreflectors and back gives a measure of the Moon's distance at that ...
Like Apollo 8, Apollo 10 orbited the Moon but did not land. A list of sightings of Apollo 10 were reported in "Apollo 10 Optical Tracking" by Sky & Telescope magazine, July 1969, pp. 62–63. [17] During the Apollo 10 mission The Corralitos Observatory was linked with the CBS news network. Images of the spacecraft going to the Moon were ...
Reports of transient lunar phenomena range from foggy patches to permanent changes of the lunar landscape. Cameron [2] classifies these as (1) gaseous, involving mists and other forms of obscuration, (2) reddish colorations, (3) green, blue or violet colorations, (4) brightenings, and (5) darkening.
Figure 1: A map showing the path of the lunar shadow as it crosses the earth. In this case, the star is Antares and the predicted date is 2027 September 7th. The left (western) ellipse represents moonrise for that region of the globe. The right (eastern) ellipse represents moon set for that region. The northern and southern path limits are shown.
The Moon's surface can scatter a laser beam and produce a sufficiently strong enough signal to be detected on Earth, resulting in ranging measurements that were accurate to within 120 meters (390 ft). Beyond this though the effects of terrain became problematic, and when combined with a returned signal strength that is both weak and temporally ...
Geological studies of the Moon are based on a combination of Earth-based telescope observations, measurements from orbiting spacecraft, lunar samples, and geophysical data. . Six locations were sampled directly during the crewed Apollo program landings from 1969 to 1972, which returned 382 kilograms (842 lb) of lunar rock and lunar soil to Earth [8] In addition, three robotic Soviet Luna ...
