우주 의학은 국제 우주 정거장에서 최우선 연구 과제였습니다.ISS) 월요일에 4명의 Expedition 68 우주비행사가 치료 중인 뼈 상태를 탐구했습니다. 궤도를 도는 연구소의 3명의 우주비행사는 하루 종일 다양한 물리학을 공부하고, 보급선을 포장하고, 스테이션 하드웨어를 정비했습니다.
Osteopromotive Bone Adhesive study.
Living in microgravity may affect skeletal stem cells and bone tissue regeneration, or bone repair. Researchers are studying a bone graft adhesive on the space station with the potential to reverse the effects of weightlessness on stem cells and bone tissue. Results may also benefit therapies for conditions on Earth such as osteoporosis. The astronauts will stay focused on the bone research activities through Wednesday.
Two cosmonauts worked on several different space physics experiments throughout Monday. Commander Sergey Prokopyev explored the behavior of clouds of highly charged particles, or plasma crystals, in a specialized chamber. Observations may lead to improved spacecraft designs, as well as a better understanding of plasmas on Earth. Flight Engineer Dmitri Petelin studied the physics of fluids exposed to magnetic and electric fields in microgravity.
The cosmonauts also worked on cargo activities and lab maintenance. Prokopyev stowed items for disposal inside the ISS Progress 81 cargo craft ahead of its departure in February. Petelin removed navigation hardware from the inside the ISS Progress 82 resupply ship and then photographed the internal area of the Nauka multipurpose laboratory module to assess its potential stowage volume. Roscosmos Flight Engineer Anna Kikina spent her day servicing life support and electronics systems.
