Lab Tests and Life Science as Station Orbits Higher Today

A docked Russian cargo craft automatically fired its engines this morning boosting the International Space Station’s altitude a little higher. During the rest of the day, the Expedition 55 crew supported life science and swapped out station hardware. Russia’s Progress 69 resupply ship docked to the Zvezda service module fired its thrusters boosting the station’s orbit today.
