Expedition 54 began Dec. 14, 2017, and continued until Feb. 27, 2018. The six-person crew consisted of Russian cosmonauts Alexander Misurkin and Anton Shkaplerov; NASA astronauts Mark VAnde Hei, Joe Acaba and Scott Tingle; and Japan Aerospace Exploration Agency astronaut Norishige Kanai. Over 2.5 months, the increment worked on science experiments that studied bacteria, the manufacture of fiber optics in microgravity, and gathered data about space debris in low-Earth orbit, to name a few. The crew also supported three spacewalks and oversaw the arrival and departure of a couple cargo spacecraft.
