Physics and biology research filled the majority of the science schedule aboard the International Space Station today. The Expedition 64 crew also put on their technician caps and worked hardware, including life support gear and air conditioning systems.

NASA astronaut Kate Rubins swapped out sample containers Tuesday morning on an experiment platform that can be placed outside Japan’s Kibo laboratory module. Scientists use experiments installed on the outside of the station to understand how space radiation and extreme temperatures affect a variety of materials. Results may improve the design of future spacecraft and the production of stronger, safer materials on Earth.

Rubins then spent the afternoon working on hardware maintenance servicing life support hardware and science gear. She first swapped batteries and chips inside ammonia measurement kits, then installed a pair of portable science freezers inside the Kibo and U.S. Destiny lab modules.

Immune system studies continued throughout Tuesday in the Russian segment of the orbiting lab. Cosmonauts Sergey Ryzhikov and Sergey Kud-Sverchkov processed their own blood and saliva samples in the morning and evening to understand how spaceflight stresses the immunity of a crew member.

Ryzhikov, the station commander on his second space mission, also refilled freon bottles to maintain the orbiting lab’s air conditioning system. Kud-Sverchkov cleaned ventilation fans and filters before checking radiation readings and smoke detectors.

The Expedition 64 trio is nearing its second full week aboard the International Space Station and is beginning the work week with a host of biomedical studies today. The three station crew members will also bring in the 20th year of continuous human habitation of the orbital lab on Nov. 2.

Flight Engineers Kate Rubins and Sergey Kud-Sverchkov with Commander Sergey Ryzhikov started Monday collecting mass measurements before splitting up for the rest of the day. After waking up, they attached themselves to a device that applies a known force to a crew member and uses the resulting acceleration to calculate an astronaut’s mass in microgravity.

Rubins spent part of the day on lab maintenance tasks replacing water filters and collecting microbe samples from station surfaces for analysis. She then serviced and inspected an array of science hardware including a Japanese external experiment platform, fluid physics research gear and finally the Advanced Plant Habitat.

Ryzhikov then joined Kud-Sverchkov for a variety of studies exploring how their bodies are adapting to microgravity. The Russian duo logged their meals and drinks throughout the day for an investigation that seeks to understand bone loss in space. The pair also worked on an experiment to improve exercise techniques to sustain long-term space exploration missions. Kud-Sverchkov later collected and stowed his saliva samples for a study looking at how the human immune system adapts to microgravity.

On Nov. 2, Rubins with fellow crewmates Ryzhikov and Kud-Sverchkov will be part of 20 years of humans continuously orbiting Earth aboard the station. They are the 64th long-term crew to live and work on the orbiting lab. The first crew to board the station was Expedition 1 on Nov. 2, 2000, with Commander William Shepherd of NASA with Roscosmos Flight Engineers Sergei Krikalev and Yuri Gidzenko.

It is back to work for three Expedition 64 crewmates today following a day of rest on Thursday. The trio is ramping up space research while continuing the upkeep of the International Space Station.

NASA astronaut Kate Rubins began her day replacing batteries in devices that detect smoke and compounds in the station’s atmosphere. She then serviced a variety of research hardware including Spectrum which images proteins in fluorescent light. Rubins then worked on a device that applies a known force to a crew member and uses the resulting acceleration to calculate an astronaut’s mass in microgravity.

Station Commander Sergey Ryzhikov had a light duty day Friday. The two-time resident of the orbiting lab spent some time dusting and cleaning crew quarters before replacing components in the Russian toilet.

First-time space flyer Sergey Kud-Sverchkov inspected Russian hardware today including a food warmer and an onboard control system. The cosmonaut Flight Engineer also configured a pair of laptop computers with assistance from mission specialists on the ground.

Three Expedition 64 crew members are sleeping in today following the departure of their Expedition 63 crewmates the day before. Back on Earth, NASA astronaut Chris Cassidy and Roscosmos cosmonauts Anatoly Ivanishin and Ivan Vagner have begun the flight back to their home space agencies.

The International Space Station is quiet today as Commander Sergey Ryzhikov and Flight Engineers Kate Rubins and Sergey Kud-Sverchkov rest after preparing their crewmates for the short ride to Earth on Wednesday. The trio will resume their normal schedule on Friday and begin revving up advanced space science to improve life for humans on and off the Earth.

The next crew to visit the orbiting lab is targeting early to mid November to launch aboard the SpaceX Crew Dragon spacecraft from Florida. Four Commercial Crew astronauts, Mike Hopkins, Victor Glover and Shannon Walker of NASA with JAXA (Japan Aerospace Exploration Agency) astronaut Soichi Noguchi, are planned to live and work on the station until Spring.

NASA astronaut Chris Cassidy and cosmonauts Anatoly Ivanishin and Ivan Vagner of the Russian space agency Roscosmos landed on Earth at 10:54 p.m. EDT in Kazakhstan. The trio departed the International Space Station in their Soyuz MS-16 spacecraft at 7:32 p.m.

Cassidy now has spent a total of 378 days in space, the fifth highest among U.S. astronauts.

After post-landing medical checks, the crew will split up to return home; Cassidy will board a NASA plane back to Houston, and Vagner and Ivanishin will fly home to Star City, Russia.

Remaining aboard the station is the three-person crew of Expedition 64 with NASA astronaut Kate Rubins, and station commander Sergey Ryzhikov and Sergey Kud-Sverchkov of Roscosmos. Upon the arrival of the SpaceX Crew-1 mission targeted to launch in November, the station’s long-duration crew will expand to seven people for the first time with the addition of NASA astronauts Michael Hopkins, Victor Glover and Shannon Walker, and Soichi Noguchi of the Japan Aerospace Exploration Agency.

Watch NASA TV for Crew Return to Earth

The Soyuz MS-15 spacecraft is seen as it lands in a remote area near the town of Zhezkazgan, Kazakhstan with Expedition 62 crew.

NASA Television and the agency’s website are now broadcasting live coverage of the return to Earth of NASA astronaut Chris Cassidy and cosmonauts Anatoly Ivanishin and Ivan Vagner of the Russian space agency Roscosmos. The Soyuz MS-16 spacecraft carrying the trio is expected to make its deorbit burn at 10 p.m. to set the spaceship on its re-entry through Earth’s atmosphere for a landing in Kazakhstan at 10:55 p.m.

While on station, Cassidy contributed to hundreds of experiments, including a study of the influence of gravity on electrolytic gas evolution, a complex electrochemical process with multiple applications on Earth and in space. Electrolysis generates bubbles that can be used to create pressure differentials in microfluidic devices, such as skin patches, used to deliver medications. Microgravity makes it possible to single out bubble growth and study its effect on the process.

During this latest mission, Cassidy served as commander of Expedition 63, contributed to hundreds of experiments, and welcomed SpaceX Demo-2 crew members Robert Behnken and Douglas Hurley of NASA– the first astronauts to launch to the space station on an American spacecraft from American soil since the retirement of the space shuttle in 2011.

Cassidy and Behnken completed four spacewalks, totaling 23 hours and 37 minutes, to upgrade station batteries. The final spacewalk was the 10th for both astronauts, making them two of only four only U.S. astronauts to complete 10 spacewalks. Cassidy now has spent a total of 378 days in space, the fifth highest among U.S. astronauts.

Cassidy also worked with Astrobee, cube-shaped, free-flying robots that may one day assist astronauts with routine duties, and conducted research for the Onco-Selectors experiment, which leverages microgravity to identify targeted cancer therapies.
