This [space] serves as an ongoing dedication to the late Carl Sagan. I will frequently update this page with all things Sagan, science & cosmos-related, in support of scientific literacy & understanding amongst the ever-increasing hominid population on our organic spaceship, Earth.
Keep looking up & remember: we are all star stuff, contemplating the stars, as our origins exist within the cosmos.
May this page bring you closer to your own individual enlightenment, further your knowledge of the universe & allow you to achieve wisdom & connectivity toward all living things for which we all share the same biological, chemical & atomic makeup.
If humans are ever to inhabit the moon, the lunar poles may well be the location of choice: Because of the small tilt of the lunar spin axis, the poles contain regions of near-permanent sunlight, needed for power, and regions of near-permanent darkness containing ice — both of which would be essential resources for any lunar colony.
The area around the moon’s Shackleton crater could be a prime site. Scientists have long thought that the crater — whose interior is a permanently sunless abyss — may contain reservoirs of frozen water. But inconsistent observations over the decades have cast doubt on whether ice might indeed exist in the shadowy depths of the crater, which sits at the moon’s south pole.
Now scientists from MIT, Brown University, NASA’s Goddard Space Flight Center and other institutions have mapped Shackleton crater with unprecedented detail, finding possible evidence for small amounts of ice on the crater’s floor. Using a laser altimeter on the Lunar Reconnaissance Orbiter (LRO) spacecraft, the team essentially illuminated the crater’s interior with laser light, measuring its albedo, or natural reflectance. The scientists found that the crater’s floor is in fact brighter than that of other nearby craters — an observation consistent with the presence of ice, which the team calculates may make up 22 percent of the material within a micron-thick layer on the crater’s floor.
