Unwrapped: Five Decade Old Lunar Selfie

Posted on Posted in NASA, TweetTagged , , Leave a comment

Here is one of the most famous pictures from the Moon — but digitally reversed. Apollo 11 landed on the moon in 1969 and soon thereafter many pictures were taken, including an iconic picture of Buzz Aldrin taken by Neil Armstrong. The original image captured not only the magnificent desolation of an unfamiliar world, but Armstrong himself reflected in Aldrin’s curved visor. Enter modern digital technology. In the featured image, the spherical distortion from Aldrin’s helmet has been reversed. The result is the famous picture — but now featuring Armstrong himself from Aldrin’s perspective. Even so, since Armstrong took the picture, the image is effectively a five-decade old lunar selfie. The original visor reflection is shown on the left, while Earth hangs in the lunar sky on the upper right. A foil-wrapped leg of the Eagle lander is prominently visible. Preparations to return humans to the Moon in the next few years include the Artemis program, an international collaboration led by NASA. via NASA https://ift.tt/3kIK31E

Wikipedia article of the day is Transandinomys. Check it out: Article-Link Summary: Transandinomys is a genus of rodents in the tribe Oryzomyini of the family Cricetidae—a grouping of medium-sized, soft-furred rice rats. It includes two species—T. bolivaris and T. talamancae—found in forests from Honduras in Central America to southwestern Ecuador and northwestern Venezuela in South America. The upperparts—brownish in T. bolivaris and reddish in T. talamancae—are much darker than the whitish underparts. Both species are characterized by very long vibrissae (whiskers), but those of T. bolivaris are particularly long. In addition, several other morphological differences distinguish the two, including wider first upper molars in T. bolivaris. Both species live on the ground, are active during the night, eat both plant and animal matter, and construct nests of vegetation. They are hosts to various external parasites. They are in no apparent danger of extinction and have been assessed as least-concern species on the IUCN Red List.
