Crew Maintains Station Operations and Space Research

The well-lit Middle Eastern cities along the Persian Gulf coast of the Arabian Peninsula to the north of Iran were photographed from the International Space Station during an orbital night pass.

The Expedition 63 crew serviced a variety of International Space Station hardware today ensuring research, power and life support systems continue operating in good condition. Heart research and team psychology studies also filled today’s science schedule.

Commander Chris Cassidy of NASA wrapped up science rack swap work that he began on Monday. He finished moving and reinstalling three advanced science facilities, known as EXPRESS racks, in three different lab modules. The rack exchanges will support future experiments being delivered on an upcoming Cygnus resupply mission from Northrop Grumman.

Afterward, Cassidy collected water samples from the potable water dispenser for analysis on Earth and on the station. The veteran astronaut also inspected U.S. module hatches and replaced pipes in the orbiting lab’s restroom, known as the Waster and Hygiene Compartment.

Three-time space station cosmonaut Anatoly Ivanishin strapped himself on an exercise bike this morning for an assessment of his cardiac activity in space. First-time space flyer Ivan Vagner assisted Ivanishin attaching sensors to the test subject and monitoring his activities during the hour-long test.

The Russian duo then checked battery temperatures and connections before studying how international space crews interact with mission controllers around the world. Ivanishin went on to set up advanced Earth observation gear while Vagner worked on power system diagnostics.

A glacier, pictured from the International Space Station, in the Laguna San Rafael National Park ends at the Rio Nevado in Aysén, Chile. The Expedition 63 crew started the workweek checking out hardware supporting life science, combustion research and ongoing Earth observations. A Russian cargo craft docked to the International Space Station is also being packed with old gear for disposal toward the end of the year. The multitude of microgravity research that takes place every day on the orbiting lab, requires regular maintenance and monitoring by the crew or scientists on the ground. The ongoing research supports innovative applications and insights benefitting Earth and space industries. Today, Commander Chris Cassidy serviced an advanced space microscope and swapped components supporting safe combustion investigations. Cassidy first configured the Light Microscopy Module , part of the Fluids Integrated Rack , which supports basic physics and biology research. Next, the veteran N

The Northrop Grumman Cygnus resupply ship is pictured about 30 meters away from the space station approaching its capture point near the Canadarm2 robotic arm. Credit: NASA TV At 4:38 a.m. EST, Expedition 64  Flight Engineer Soichi Noguchi of the Japanese Aerospace Exploration Agency used the International Space Station’s robotic Canadarm2 to grapple the Northrop Grumman Cygnus spacecraft as Flight Engineer Michael Hopkins of NASA monitored Cygnus systems during its approach. Next, ground controllers will command the station’s arm to rotate and install Cygnus, dubbed the S.S.  Katherine Johnson , on the Earth-facing port of the station’s Unity module . NASA Television coverage of installation will begin at 6 a.m., and installation of the Cygnus spacecraft to the space station is expected to be completed later this morning. Cygnus will remain at the orbiting laboratory for a three-month stay. Watch live on the agency’s website or on the NASA app. Learn more about space station activi

Three spaceships are pictured attached to the space station as the orbital complex flew 261 miles above the Bay of Bengal. Two NASA astronauts are getting their tools and spacesuits ready for Sunday’s spacewalk to ready the International Space Station for new solar arrays. Meanwhile, the rest of the Expedition 64 crew focused on a variety of space research on Thursday. NASA Flight Engineers Kate Rubins and Victor Glover are finalizing their preparations for a planned six-and-a-half hour spacewalk set to begin Sunday at 6 a.m. EST. NASA TV will begin its live spacewalk beginning at 4:30 a.m. Rubins and Glover configured spacewalk tools and checked U.S. spacesuits today before calling down to experts in Mission Control to report on their readiness. The duo today also continued reviewing the spacewalk procedures they will use to upgrade power channels that will soon support new solar arrays. Those solar arrays will be shipped on upcoming Space Dragon cargo missions for installation th
