Imaging of Mercury during MESSENGER's third flyby

Imaging of Mercury during MESSENGER's third flyby
Imaging of Mercury during MESSENGER's third flyby As MESSENGER approaches for its third flyby of Mercury, it will capture images covering the last major swath of the planet not previously imaged by any mission. On its way out, its view will be very similar to the one it had during flyby 2. After the third flyby is completed, only the poles will remain unimaged by MESSENGER. NASA / JHUAPL / CIW
