NASA's Space to Ground is your weekly update on what's happening aboard the International Space Station.


What's the coldest place you can think of? Temperatures on a winter day in Antarctica dip as low as −120ºF (−85ºC). On the dark side of the Moon, they hit −280ºF (−173ºC). But inside NASA's Cold Atom Laboratory on the International Space Station, scientists are creating something even colder.


NASA Flight Engineer Serena Auñón-Chancellor, Expedition 57 Commander Alexander Gerst of ESA (European Space Agency) and Soyuz commander Sergey Prokopyev of the Russian space agency Roscosmos undocked from the International Space Station at 8:40 p.m. EST to begin their trip home.


The Expedition 57 commander handed over control of the International Space Station today in a traditional ceremony. He and two of his crewmates will then head back to Earth Wednesday just in time for the holidays.


Today - Airway Monitoring: Today the crew performed the setup activities for the upcoming Airway Monitoring US Lab (ambient) session.


The Copernicus Sentinel-2A satellite takes us over Mount Triglav in Slovenia. At 2800 m above sea level, the mountain is the highest in the country and a significant source of national pride, even featuring on the Slovenian coat of arms.


Today - Molecular Muscle: Crewmembers removed the Molecular Muscle samples from the Kubik-5 facility and inserted the samples into the MELFI-3 (Minus Eighty-Degree Laboratory Freezer for ISS).


Half of the Expedition 57 crew is getting ready to depart International Space Station while the other half is getting used to life on orbit. Amidst those preparations, all six space residents are researching what microgravity does to their bodies while keeping the orbital lab in tip-top shape.


The Expedition 57 crew were allowed to catch a few extra hours of sleep today after a lengthy spacewalk Tuesday by the two cosmonauts on board.


Expedition 57 Flight Engineers Oleg Kononenko and Sergey Prokopyev of Roscosmos completed a spacewalk lasting 7 hours and 45 minutes.


Today - Molecular Muscle: Crewmembers performed sample inserts into the Kubik incubator facility, photography documentation, and a status check of the experiment run.


When traveling in space, astronauts experience physiological changes normally associated with aging, such as bone loss, muscle deterioration and altered immune systems.
