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.

Two veteran International Space Station crew members will swap command of the orbiting lab during the traditional Change of Command Ceremony this afternoon.

The six-member space station crew will gather together at 4:15 p.m. EDT when Expedition 63 Commander Chris Cassidy of NASA ceremonially hands control of the station to Expedition 64 cosmonaut Sergey Ryzhikov of Roscosmos. Ryzhikov will officially begin his command on Wednesday when Cassidy and Flight Engineers Anatoly Ivanishin and Ivan Vagner undock from the station at 7:32 p.m. inside the Soyuz MS-16 crew ship. All the activities will be broadcast live on NASA TV.

Meanwhile, science and maintenance activities are moving right along inside the space station. Cassidy and NASA Flight Engineer Kate Rubins both had time set aside today collecting blood, saliva and urine for stowage and later analysis. Rubins then checked out research hardware and plumbing gear before familiarizing herself with station systems.

Ryzhikov and Vagner spent a couple of hours swabbing surfaces in the Russian segment of the station collecting microbial samples and placing them in petri dishes for incubation and analysis. Vagner also joined Ivanishin to test the Lower Body Negative Pressure suit for its ability counteract some adverse effects of long-duration spaceflight and prepare the duo for the return to Earth’s gravity.

New space flyer Sergey Kud-Sverchkov synchronized cameras with clocks on station laptop computers and worked on Russian plumbing tasks. The cosmonaut also is getting used to living and working in space for the first time.

Two veteran International Space Station residents will have a Change of Command ceremony on Tuesday before the Expedition 63 crew returns to Earth the following day. Meanwhile, the Russian portion of the crew has temporarily sealed a leak on the orbiting lab.

Commander Chris Cassidy of NASA will hand over control of the space station to cosmonaut Sergey Ryzhikov on Tuesday. The duo will be joined by the rest of their crewmates for the traditional event live on NASA TV starting at 4:15 p.m. EDT.

Cassidy will spend one more night in space with Flight Engineers Anatoly Ivanishin and Ivan Vagner before departing the station on Wednesday inside the Soyuz MS-16 crew ship. They will undock from the Poisk module at 7:32 p.m., re-enter the Earth’s atmosphere just over three hours later and parachute to a landing in Kazakhstan at 10:55 p.m. (Oct. 22, 7:55 a.m. Baikonur time). All the activities will be broadcast live on NASA TV.

Expedition 64 officially begins when Cassidy undocks with his two Russian crewmates. New station Commander Ryzhikov will stay in space until April with Flight Engineers Kate Rubins of NASA and Sergey Kud-Sverchkov of Roscosmos.

Russian crew members were able to temporarily seal the air leak teams have been investigating aboard the station. The leak, which has been investigated for several months, continues to pose no immediate danger to the crew at the current leak rate. Roscosmos engineers are working with the station crew to develop a forward plan to permanently seal the suspected leak location.
