In the wee hours of Tuesday morning, we’ll be treated to a total lunar eclipse. But the spacecraft at the Moon will get a solar eclipse instead, as the Earth crosses in front of the Moon. 359 more words

The Moon has a wobble. Observations of the Moon show a wobble (Libration) during its synchronously locked orbit around Earth.
The trouble with Libration is that a picture (or in this case, a video) can explain so much better the effect an elliptical orbit and the rotational synchronicity can have on the image an astronomical body has when observed from Earth. 8 more words

After decades of searching, NASA scientists have detected the veil of dust kicked up by tiny meteoroid impacts on the moon. The Apollo astronauts and many spacecraft had tried to detect sunlight reflected from the dust and failed. 115 more words
Scientists, using cameras aboard NASA’s Lunar Reconnaissance Orbiter (LRO), have created the largest high resolution mosaic of our moon’s north polar region. The six-and-a-half feet (two-meters)-per-pixel images cover an area equal to more than one-quarter of the United States. 156 more words

The first American spacecraft to photograph the moon up close did its work in the last 15 minutes of its life. On the morning of July 31, 1964, the Ranger 7 spacecraft was falling toward the lunar surface at the end of a three-day trip that was always intended to culminate in a suicide plunge. 283 more words
I really don’t get tired of these. ;-) So here are some more!
The Gravity Recovery And Climate Experiment (GRACE) mission, a pair of identical spacecraft, deployed together, which measure tiny variations in their separation to probe the Earth’s gravity field with unprecedented precision. 138 more words
