Expedition 59

Expedition 59

Expedition 59 began March 15, 2019, and will continue until June 2019. According to NASA, the Expedition 59 crew, which consists of NASA astronauts Anne McClain, Nick Hague and Christina Koch; Russian cosmonauts Oleg Kononenko and Aleksey Ovchinin; and Canadian Space Agency astronaut David Saint-Jacques, will perform dozens of experiments in areas ranging research on the human body, research on regolith simulants, test free-flying robots inside the station and study the complex dynamics of the Earth’s atmospheric carbon cycle. Additionally, several spacewalks will be performed to upgrade the outpost.

Expedition 57

Expedition 57

Expedition 57 began Oct. 4, 2018, and continued until Dec. 20, 2018. The crew was tasked with performing dozens of experiments and overseeing the arrival of several cargo resupply vehicles and perform spacewalks. The initial three-person crew — European Space Agency astronaut Alexander Gerst, NASA astronaut Serena Aunon-Chancellor and Russian cosmonauts Sergey Prokopyev — was expected to be joined by Russian cosmonaut Aleksey Ovchinin and NASA astronaut Nick Hague on Oct. 11, 2018. However, an abort during their ascent in Soyuz MS-10 prevented them from joining the crew. They were instead joined by Russian cosmonaut Oleg Kononenko, NASA astronaut Anne McClain, and Canadian Space Agency astronaut David Saint-Jacques.

Expedition 56

Expedition 56 began June 3, 2018, and continued until Oct. 4, 2018. The six person crew — NASA astronauts Drew Feustel, Ricky Arnold and Serena Aunon-Chancellor; Russian cosmonauts Oleg Artemyev and Sergei Prokopyev; and European Space Agency astronaut Alexander Gerst — is tasked with performing experiments that study the behavior of atoms in extreme conditions, explore microbial growth aboard the outpost and other tests to expand navigation capabilities for future travel beyond low-Earth orbit.

Expedition 55

Expedition 55 began Feb. 27, 2018, and continued until June 3, 2018. Its six-person crew — NASA astronauts Scott Tingle, Drew Feustel and Ricky Arnold; Russian cosmonauts Anton Shkaplerov and Oleg Artemyev; and Japan Aerospace Exploration Agency astronaut Norishige Kanai — was tasked with performing experiments studying Earth’s atmosphere and the effect of microgravity on bone marrow in addition to materials sciences and biological sciences. The increment also saw several visiting vehicle arrivals and performed two spacewalks.

Expedition 54

Expedition 54

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.

Expedition 53

Expedition 53 began Sept. 2, 2017, and continued until Dec. 14, 2017. Consisting of NASA astronauts Randy Bresnik, Mark Vande Hei and Joe Acaba; Russian cosmonauts Sergey Ryazansky and Alexander Misurkin; and European Space Agency astronaut Paolo Nespoli, the six-person crew performed experiments that studied cosmic ray particles, the manufacturing of fiber optic filaments in microgravity as well as targeted therapies to improve muscle atrophy, among others. Additionally, three spacewalks were performed and several cargo ships resupplied the multinational outpost.

Expedition 52

Expedition 52 began June 2, 2017, and continued until Sept. 2, 2017. Russian cosmonauts Fyodor Yurchikhin and Sergey Ryazansky; NASA astronauts Jack Fischer Peggy Whitson and Randy Bresnik; and European Space Agency astronaut Paolo Nespoli spent the three-month increment performing studies over more efficient solar arrays, the physics of neutron stars and new drugs that could potentially fight osteoporosis. One spacewalk was performed and three cargo ships supplied the outpost during that time period.

Expedition 51

Expedition 51

Expedition 51 began April 10, 2017, and continued until June 2, 2017. Over two months, the five-person crew — NASA astronauts Peggy Whitson and Jack Fischer; Russian cosmonauts Oleg Novitskiy and Fyodor Yurchikhin; and European Space Agency astronaut Thomas Pesquet — oversaw two spacewalks and a single cargo ship arrival. Additionally, among the dozens of experiments performed during their stay the crew studied the microorganisms present aboard the ISS and measured the charges of cosmic rays.
