The eminent site XKCD has published this picture that compares the surface areas of notable rocky celestial bodies in our solar system. The four giant planets are excluded because they lack mappable surfaces. The arrangement would be laid out nicely on the type of Ringworld that Larry Niven proposed in some of his stories — link >>>
One of my favourite science fiction authors, pulp queen Leigh Brackett, was born one hundred years ago on December 7, 1915. She wrote interplanetary adventures in a dramatic solar system: canals and ancient horrors on Mars, jungles and dark science on Venus, and so on. Her stories frequently moved in the borderland between SF and fantasy, because the genre boundaries were less clearcut in those days.
Leigh Brackett’s final feat was the manuscript to Star Wars V: The Empire Strikes Back, which so far is my favorite in the Skywalker Saga. Unfortunately she died before the completion of the movie.
Here is an article commemorating her centenary — link >>>
Wanderers is a short science fiction film by Erik Wernquist, a digital artist from Stockholm, Sweden. He explains its underlying idea:
The film is a vision of our humanity’s future expansion into the Solar System. Although speculative, the visuals in the film are based on scientific ideas and concepts of what our future in space might look like, if it ever happens. All locations depicted in the film are digital recreations of actual places in the Solar System, built from real photos and map data where available.
NASA’s Messenger probe has been investigating Mercury for some years. Among other things, it has photomapped 100 percent of the planetary surface. Mercury has one unique terrain feature: extremely long escarpments created by the planet’s slow shrinking due to internal cooling.
