Bone cells and now heart cells are on the space research agenda for the Expedition 62 crew. The International Space Station continues gearing up for more space investigations recently delivered aboard the SpaceX Dragon resupply ship.

NASA Flight Engineer Jessica Meir turned her attention today to a new experiment exploring cardiac activity in microgravity. She tended to heart cells swapping media that nourishes the samples being observed and manipulated with magnetic sensors. The results could inform measures to keep astronauts healthy on long-term missions and possibly treat heart conditions on Earth.

Bone health is also important for humans living and working on and off the Earth. Over in the Japanese Kibo laboratory module, NASA astronaut Andrew Morgan worked in the Life Science Glovebox servicing bone cell samples for an experiment that began in February. That research is comparing samples nurtured in weightlessness to a set of samples that are magnetically levitated in a lab on Earth. Insights could prove valuable when treating bone ailments such as osteoporosis.

The pair also split their time on several other investigations ranging from radiation detection to protein crystals. Radiation detectors were retrieved from Dragon and installed throughout the station to characterize the orbital lab’s radiation dosage and distribution. The crew also looked at protein crystals that grow better in space than on Earth, for a pair of studies, PCG-10 and JAXA Moderate Temp PCG, supporting the development of more effective medications.

Commander Oleg Skripochka focused on Russian communications gear throughout the day testing two-way audio and video satellite links. He also spent some time exploring advanced photography techniques to locate Earth targets.
