Hera Swings Past Mars, Sees Deimos From a New Angle

Gravitational slingshots are now a common part of space missions where the trajectory of a spacecraft is altered using the gravity of another body. These often bring fabulous opportunities for an extra bit of bonus science such as that demonstrated by ESA’s Hera mission on its way to asteroid Dimorphos. It’s following up on the DART 2022 impact but to get there, it’s used the gravity of Mars. It came within 5,000 km of the red planet and on its way, was able to take a look at Mars’ smaller moon Deimos from its far side.
