Until just a few years ago, a plot of mass versus size of other worlds would have looked pretty sparse and uninformative. But thanks to the tireless efforts of exoplanet astronomers, we now know fairly precise masses and radii for hundreds of distant worlds.

Curiosity has driven onward from Namib dune across a highstanding unit of rock called the Naukluft Plateau. Despite some frustrating sols lost to a short circuit in the RTG and DSN troubles, the rover has made progress, and performed lots of 3D imaging of weirdly wind-eroded rocks.

Ever wanted to stand on Mars and watch a sunset? Unfortunately for many of us, it will never be something that we get to experience in person. But thanks to our robotic emissaries on Mars, and some careful processing of images from NASA's Planetary Data System, we can get a sense of what it’s like.
