CubeSats fly free after leaving the NanoRacks CubeSat Deployer on the International Space Station earlier in the week.

The crew was back at work today with more life science studies and human research. Cygnus cargo transfer work is ongoing as robotics controllers prepare for an external video survey.

Mice continue to be observed today for the Rodent Research-3 study. The astronauts are measuring their bone density to learn how microgravity affects muscles and bones and potentially helping crews in space and citizens on Earth stay healthier.

Astronaut Jeff Williams scanned his leg with an ultrasound today for the long-running Sprint study. The research is exploring new space exercise techniques that may minimize muscle and bone loss on long duration missions. The cosmonauts were collecting blood and saliva samples for analysis as they explore how living in space affects the human body.

Cargo transfers are over half way complete as the Cygnus commercial space freighter targets a mid-June departure from the Unity module. The Canadarm2 robotic arm will link up with the DEXTRE robotic hand tonight. Robotics controllers will then conduct a video scan of the external RapidScat system that monitors weather patterns on the Earth’s oceans.
