What does the Moon’s North Pole look like?

The Moon's North Pole

This image of the moon’s north polar region was taken by the Lunar Reconnaissance Orbiter Camera, or LROC. One of the primary scientific objectives of LROC is to identify regions of permanent shadow and near-permanent illumination. Since the start of the mission, LROC has acquired thousands of Wide Angle Camera images approaching the north pole. From these images, scientists produced this mosaic, which is composed of 983 images taken over a one month period during northern summer. This mosaic shows the pole when it is best illuminated, regions that are in shadow are candidates for permanent shadow.

Perspective on solar power

The left square, labelled “world,” is around the size of Austria. If that area were covered in solar thermal power plants, it could produce enough electricity to meet world demand. The area in the center would be required to meet European demand. The one on the right corresponds to Germany’s energy demand.

I wonder how this theoretical area compares to total oil spill area coverage or areas affected by coal strip-mining.

Dona, the charity robot

DONA is the robot that interactively solicits donations from passers-by. The robot roams around in a public outdoor space and solicits donations from passers-by by engaging them through pet-like inter-action.
