A pair of Expedition 52 astronauts from NASA aboard the International Space Station today explored how microgravity causes bone loss in space. The commander from Roscosmos also worked on life support maintenance tasks throughout Wednesday.
NASA astronauts Peggy Whitson and Jack Fischer studied a new drug therapy to determine its potential to prevent bone loss. The duo worked inside the Destiny lab module and used a bone densitometer to measure bone minerals in mice living in the Rodent Research habitat. The new drug may slow or reverse bone loss in astronauts during spaceflight and possibly help patients on Earth suffering bone loss syndromes.
Commander Fyodor Yurchikhin was on the opposite side of the station today doing plumbing work and transferring water from the new Progress 67 cargo craft into the Zvezda service module. The veteran cosmonaut also replaced water hoses and worked on air purification gear.
