Planetary Exploration Timelines: A Look Ahead to 2016

Emily Lakdawalla • December 31, 2015 • 19

How many planetary exploration missions are there, and where are they? These days, it's hard to keep track, because there are so many. I plan to begin the new year by taking stock of active missions, figuring out what each has set out to do and accomplished so far, but first I want to step back to consider the spread of missions across the solar system as a whole.

People often ask me to produce one of my scale-comparison montages featuring the small moons of the outer solar system. I'd love to do that, but Galileo's best images of Jupiter's ringmoons lack detail compared to Cassini's images from Saturn.

The not-planets

Now that I have a reasonable-resolution global color view of Pluto, I can drop it into one of my trademark scale image montages, to show you how it fits in with the rest of the similar-sized worlds in the solar system: the major moons and the biggest asteroids.

Adding Churyumov-Gerasimenko to my scale comparison of comets and asteroids

Having found a color photo of the comet, I finally added Churyumov-Gerasimenko to my scale comparison of comets and asteroids visited by spacecraft.
