Science research continues and yields new information about bone loss research aboard the International Space Station.
The five-member crew aboard the International Space Station was back at work Thursday researching how living in space affects the human body. Two of today’s experiments looked at how microgravity weakens bones and alters DNA.
Commander Peggy Whitson joined Flight Engineer Thomas Pesquet for the OsteoOmics bone loss study. The experiment compares bone loss in the free-floating environment of microgravity versus magnetic levitation on Earth and observes the molecular changes that place. Results may improve the health of crews in space and humans on Earth, possibly counteracting bone loss and preventing bone diseases.
Pesquet later checked samples for the Genes In Space experiment that is based on a winning proposal submitted during a student science competition. That study is testing new technology to track how a space mission alters an astronaut’s DNA and impacts their immune system.
The rest of the crew, including NASA astronaut Jack Fischer and cosmonauts Fyodor Yurchikhin and Oleg Novitskiy, split their time between loading a Russian cargo craft, crew orientation and systems maintenance.
Earlier, in the previous day, more discussion of current science research that details the altering of DNA in space-faring astronauts:
The Expedition 51 quintet studied how long-term space missions affect bone loss and explored new ways to exercise in space today. The crew also reviewed emergency procedures and equipment onboard the International Space Station.
Astronauts Peggy Whitson and Thomas Pesquet set up samples today for the OsteoOmics bone study that will last four weeks on the station. Doctors are researching the molecular mechanisms that impact the bones of astronauts living in space. The experiment could lead to therapeutic insights improving the health of astronauts in space and humans on Earth.
New Flight Engineer Jack Fischer performed an ultrasound scan of his leg muscles with assistance from Whitson and remote guidance from ground personnel. The ultrasound data is being collected for the Sprint study that is exploring the benefits of high-intensity, low-volume exercise to maintain muscle, bone and heart functions.
Whitson and Fischer then joined veteran cosmonaut Fyodor Yurchikhin for a couple of hours of emergency training. The trio took note of safety gear locations, followed escape paths to the docked Soyuz vehicles and inspected hatches for proper clearances.
