Life Science, Spacewalk Preps as Station Orbits Higher
 Astronaut Nicole Mann is pictured inside the seven-window cupola as the SpaceX Dragon cargo craft approaches the space station on Nov. 27, 2022.   Science and spacewalk preparations kept the Expedition 68  crew busy throughout Wednesday. Meanwhile, the International Space Station  is orbiting slightly higher after a docked cargo craft fired its engines during the morning.  NASA astronauts Nicole Mann  and Frank Rubio  began the morning cleaning and stowing biology hardware used to transfer research samples from the SpaceX Dragon resupply ship  into the space station’s U.S. Destiny laboratory module. Those samples will soon be examined to understand how microgravity affects the regeneration of skeletal stem cells  possibly improving therapies for bone conditions on Earth and in space.  NASA Flight Engineer Josh Cassada  started his day supporting student-designed botany experiments packed inside specialized tubes delivered aboard Dragon. Flight Engineer Koichi Wakata  of the Japan Aero...
