Of course, we’ve learned in the past few years that Moon isn’t so dry and definitely isn’t boring, and the same goes for Mercury as its been studied by […]

Closest to Mercury
The MESSENGER spacecraft is making its closest approach to the surface of the planet Mercury right now, just 199 km (123.7 miles) above the surface. It has also reached a new milestone, a full 3,000 orbits of the planet. Before the spacecraft arrived in 2011, we had only imaged half of Mercury’s surface during a […]
Mercury’s Volcanoes
Here is some more interesting news coming out about Mercury from the MESSENGER spacecraft. It was long thought that Mercury didn’t really have major, explosive volcanism in the past, like the Mount St. Helens eruption of 1980. For that, you need volatiles, or compounds that boil at relatively low temperatures, astronomically speaking. When the planets […]
MESSENGER Milestone
Last week, NASA announced that the MESSENGER spacecraft surpassed a huge milestone having returned 200,000 images of Mercury back to Earth. We say, congratulations! You deserve the best high-five ever! MESSENGER is now in its second extended mission studying Mercury and its environment. As the first spacecraft to orbit the innermost planet to the Sun, […]
Now Introducing: Mercury Mappers
It’s here! A brand new citizen science project! Everyone, welcome Mercury Mappers to our happy family. Technically, it is still in “beta” which means that all the site content isn’t in place, but we are so excited to have the data and tools up and running that we’re going ahead and sharing it anyway. This […]
