Mercury is a mystery.
Just two spacecraft have ever flown by the closest planet to the sun. Now the BepiColombo mission, a joint European-Japanese science undertaking, is on track to orbit and closely observe the cratered planet in 2025.
The endeavor, involving two research spacecraft hitching a ride on a larger vessel (the Mercury Transfer Module), just completed its first flyby of Mercury on Oct. 1, and it sent back black-and-white images of the planet from some 620 miles (1,000 km) to 1,500 miles (2418 km) above the planet's surface.
"It was an incredible feeling seeing these almost-live pictures of Mercury," Valentina Galluzzi, a scientist working on the BepiColombo mission, said in a statement.

Once BepiColombo starts orbiting Mercury in 2025 (after numerous flybys to fall into the planet's orbit), the probes will start researching the planet's elusive history.
"For example, [the mission] will map the surface of Mercury and analyse its composition to learn more about its formation," writes the European Space Agency. "One theory is that it may have begun as a larger body that was then stripped of most of its rock by a giant impact. This left it with a relatively large iron core, where its magnetic field is generated, and only a thin rocky outer shell."
