Mission overview

Expedition 52/53 launch and docking

Soyuz MS-05 launched on July 28, 2017, transporting Randy Bresnik, Sergey Ryazansky and Paolo Nespoli, who would make up the Expedition 52/53 crew.^[5] MS-05 docked with the Rassvet module six hours later.^[6]

September 2017 - Research Mission Started

Expedition 53/54 launch and docking

Soyuz MS-06 launched on September 13, transporting Alexander Misurkin, Mark T. Vande Hei and Joe Acaba.^[7] MS-06 docked with the (Poisk (MRM-2) module six hours later.

Dragon Brought Back ISS Experiments

On September 17, the SpaceX CRS-12 Dragon cargo spacecraft was released by Bresnick and Nespoli using the Canadarm2, clearing the Harmony module's docking port.^[8] It touched down in the Pacific Ocean southwest of Long Beach, California.^[9] It landed with the Lung Tissue Experiment,^[9] which grew lung tissue using stem cells in microgravity,^[10] the CASIS PCG7 study,^[9] which grew larger versions of the protein LRRK2 to help study Parkinson's disease,^[11] and mice from the Rodent Research-9 study,^[9] that looked at cartilage loss in hip and knee joints.^[12]

September research

Nespli and Ryazanskiy were the subjects of a bone marrow experiment^[13] that looked at the negative effects of microgravity on bone marrow and blood cells produced in bone marrow.^[14] Bresnik was the subject of a study on physiological changes due to microgravity,^[13] he is one of 33 astronauts that had signed on to participate in NASA's Biological Specimen Repository.^[15] Vande Hei worked on a camera for the Meteor experiment,^[16] which took high-resolution video and images of the Earth's atmosphere for space-based observations of meteor chemical composition.^[17] Acaba installed a Fast Neutron Spectrometer^[16] that had a better suited technique for measurements in mixed radiation fields.^[18] Ryazanskiy, Nespoli and Bresnik took measurements of themselves for Sarcolab-3,^[16] to investigate the deterioration of the calf muscle where it joins the Achilles tendon.^[19] Bresnik and Nespoli also tested out a Miniature Exercise Device-2 (MED-2)^[20] that used small robotic actuators to provide motion and resistance for crew workouts in a smaller package than previous exercise devices.^[21] Acaba setup hardware for the Veggie-3 experiment^[22] that grew Extra Dwarf Pak Choi, Amara Mustard and Red Romaine Lettuce to set the ground work to feed future long-duration missions to space.^[23] Ryazanskiy and Acaba installed radiation sensors on the U.S. portion of ISS^[24] to characterize the radiation environment aboard the station.^[25]

October 2017 - Three EVAs and a Progress

EVA 1 - Robotic Arm work

On October 5, Bresnik and Vande Hei completed a 6 hour and 55 minute spacewalk.^[26] They replaced of the two Latching End Effectors (LEE) on Canadarm2.^[26] They also were able to get ahead by removing insulation from a DC switching unit and preparing a flex hose rotary couple.^[26] This was Vande Hei's first spacewalk and Bresnik's third of their careers.^[26]

EVA 2 - Lubrication and camera fix

For their second spacewalk in less than a week, Bresnik and Vande Hei completed a 6 hour and 26 minute spacewalk on October 10.^[27] They lubricated the LEE they installed on October 5, replaced a faulty camera system, replaced a smudged lens cover and removed two handrails outside the Tranquility module.^[27] This would be Vande Hei's second space walk and final one of this mission.^[27]

Progress MS-07 resupply

After a scrubbed launch attempt on October 12,^[28] the Progress MS-07 resupply ship launched from Baiknour Cosmodrome on October 14^[29] and docked with the station on October 16 about 252 miles over eastern China.^[30] The Progress had three tons of food, fuel and supplies for the station.^[31]

EVA 3 on October 20, 2017

EVA 3 - Canadarm2 camera install

On October 20, Bresnik and Acaba exited the station for their 3rd spacewalk of the mission.^[32] They installed a new camera system on the end of Canadarm2's LEE, an HD camera on the starboard truss of the ISS and replaced a fuse on the Dextre robotic arm.^[32] Bresnik also installed a new radiator grapple bar, prepped one of two spare pumps and started work on the second.^[32] This was Bresnik's 5th career spacewalk, bringing his total EVA hours to 32, and Acaba's third spacewalk, bringing his total hours to 19.^[32]

November 2017 - Science and Cygnus

Science ambassadors, space culture and research

In addition to their duties as researchers and maintenance technicians, astronauts Vande Hei and Acaba shared their science and technology studies with students from Shaker Heights High School in Cleveland, Ohio.^[33] The crew also documented life aboard the station for the CSA's study called "At Home in Space",^[33] testing a hypothesis that despite their different backgrounds, due to the isolation and confined environment of the ISS, astronauts share a common space culture.^[34] Vande Hei also setup gear to analyze the air in the space station for dust^[35] to highlight any health impacts and maintain crewmember well being.^[36] Nespli participated in a Fine Motor Skills study^[35] and how those motor skills are affected by a microgravity environment.^[37] To monitor microgravity vision impairment,^[38] Misurkin, Ryazanskiy, Nespoli and Vande Hei examined each other's eyes.^[39]

Cygnus CRS OA-8E "S.S. Gene Cernan" resupply

After a scrubbed launch attempt on November 11,^[40] the Cygnus resupply ship, named after Gene Cernan, launched atop an Orbital ATK Antares rocket on November 12^[41] from the Wallops Flight Facility in Virginia.^[42] The spacecraft docked with the ISS on November 14 with 7,400 pounds of research and supplies.^[43] The Bigelow Expandable Activity Module (or BEAM) was outfitted in late November for future stowage operations by removing excess gear including inflations tanks and sensors.^[44] The old gear from BEAM and trash was placed into the Cygnus resupply ship for disposal.^[44] The spacecraft was detached from the station on December 5 by Vande Hei, Acaba and ground controllers.^[45]

December 2017 - Station handover to Expedition 54

On December 13, with an official change of command ceremony, Expedition 53 Commander Randy Bresnik handed the station over to Expedition 54 Commander Alexander Misurkin.^[46] They undocked from the station on December 14, ending Expedition 53 and starting Expedition 54.^[47] They touched down later that day southeast of Dzhezkazgan in Kazakhstan.^[48] At the end of the mission, Bresnik had logged 150 days in space over two missions, Ryazanskiy had 306 days over two missions and Nespoli logged 313 days over three missions.^[48]
